12:01 AM veegee: Trojan's seemingly high spec of 2.7V/cell equalization voltage actually correct.
12:08 AM veegee: Actually the voltage doesn't matter for equalization at all. It's entirely about the current and specific gravity of the electrolyte. Once the specific gravity stops rising, that's when you know it's absolutely fully charged. On a chemistry level, that makes perfect sense. The current is what drives the reaction and puts the sulfur back into the electrolyte
12:08 AM veegee: I just set a "safe" limit of 17V for a 6 cell battery, which it'll never rise to and set the equalization current to about 4A/100Ah for a couple of hours and that brings it to full charge every time
12:09 AM veegee: Need to test some flooded NiCd and NiFe just for fun
01:34 AM miss0r: veegee: Interesting!
01:34 AM miss0r: Let me know once you have a result
02:04 AM Deejay: moin
02:18 AM veegee: miss0r in Canada, we have our own shitty brand from Canadian Tire (maybe like harbour freight but shittier). They sell a group 31 deep cycle battery, 105Ah for a little under $200 CAD. I checked the reviews only after I bought it and they're pretty bad. Most people report failure within 2 years.
02:19 AM veegee: So far, I've been cycling it under lab conditions to 50% DoD and it's holding its capacity very well (using my custom charge profile)
02:19 AM veegee: 50 cycles so far. If it gets to 300, that's passable for this brand
02:21 AM veegee: Rolls Surrette, Trojan etc. mid-grade batteries are rated for 2,000 cycles to 50% DoD and their "industrial" cells are rated to over 4,000 cycles to 50% DoD with a 20 year service life
02:23 AM veegee: I believe it. Lots of renewable energy/off grid installations use them and get very good service life. Can't find anyone complaining about their mid-grade cells. Also very reasonably priced
02:23 AM veegee: just under $200 CAD/kWh
02:24 AM veegee: US Battery XC2 cells are on the same level, 2,000 cycles to 50% DoD and they publish modern charging techniques to keep improving service life
02:27 AM veegee: AGM is a waste of money for any deep cycle applications. For some reason, no one seems to be making an AGM deep cycle battery that can do more than 1,250 cycles to 50% DoD. They're also twice the cost. Completely pointless
02:30 AM veegee: Tubular gel (OPzV) seems to have excellent cycle life and service life and doesn't suffer from acid stratification. Can't find any pricing information though :(
02:58 AM sensille: is anyone here using a tumbler to finish milled aluminum parts?
03:27 AM miss0r: veegee: that makes me sad to hear. as I have installed AGM batteries in my offroad-camper convertion. :)
03:27 AM miss0r: sensille: y es, it happens
03:30 AM sensille: miss0r: do you have any information on which medium to use?
03:31 AM miss0r: sensille: Honnestly I can't remember the name I used some time ago that made a damn good surface finish. But I've gotten decent results with a medium hardness ceramic peddle
03:31 AM miss0r: The triangular ones... hang on, let me get a bag
03:31 AM miss0r: Gunson 77161
03:32 AM miss0r: but beware; these only give a good result with somewhat hard alu. (T6 preferably)
03:32 AM sensille: great, thanks. and do you use it in a rotating tumbler or a vibrating one?
03:32 AM miss0r: I've heard talk of using a progressively finer mix over a few tumbling runs for an excellent result
03:33 AM miss0r: both. but I seem to be getting the best result with the vibrating one
03:33 AM miss0r: (for alu that is)
03:33 AM sensille: hm. i want to build one, and rotating seems to be a bit easier
03:34 AM sensille: but good to know, i'll look closer into vibrating ones
03:34 AM miss0r: but one of those adjustable speed vibrators
03:34 AM miss0r: dirt cheap and it lets you fine tune it
03:35 AM miss0r: sensille: Part straight from the vibrating tumbler: https://imgur.com/a/U08jUO5
03:36 AM miss0r: also, when looking for a vibrator. Choose one with a very short stroke length. i.e. the offcenter mass should not be off center by alot. you want small fast vibrations with the softer metals
03:37 AM XXCoder: funny when off context
03:37 AM miss0r: hehe indeed :D
03:37 AM sensille: very nice
03:39 AM sensille: should be that hard to build... so only off-center by a few mm?
03:40 AM miss0r: yeah. I made mine adjustable. but I found that doing the softer materials I always end up with a very short stroke. (I engraved a line) and that is probably only 1.2-1.5 mm off center
03:42 AM miss0r: but to be fair, I don't feel it's an exact science. It will probably depend alot on the design/selfresonance of your tub ect.
03:42 AM miss0r: so I guess adjustable is the way to go
03:45 AM sensille: do you know roughly what rpm to use? i guess the motor doesn't have to be that powerful at that stroke length
03:46 AM miss0r: excellent question. I've never measured the rpm...
03:47 AM miss0r: I actualy have no idea. it almost sounds like my electrical shaver.
03:47 AM miss0r: a model with the blade is oscilating side to side
03:47 AM miss0r: perhaps a bit slower :D
03:47 AM miss0r: it takes more power than you'd think :) once you have everything moving around, it takes alot actualy
03:48 AM miss0r: well.. again, it always depends on the size of tub/size of parts/mass of media ect. it has to be able to throw/vibrate that stuff around
03:50 AM miss0r: anyway. I better get back to vacuuming before the misses gets home :D cya
03:50 AM sensille: thanks for the info :)
05:33 AM JT-Cave: morning
05:33 AM XXCoder: yo
06:22 AM Tom_L: morning
06:39 AM JT-Cave: tad warmer today
06:40 AM XXCoder: yo
06:40 AM Tom_L: 37F
06:40 AM JT-Cave: nice
06:41 AM Tom_L: hi 44
08:57 AM JT-Cave: supposed to rain this afternoon
08:57 AM JT-Cave: that will make a big mess
10:01 AM sensille: miss0r: maybe this motor?
10:01 AM sensille: https://www.ebay.de/itm//202473747760
10:44 AM miss0r: sensille: I'm sure its fine for alot of purposes. The thing to keep in mind is the strength of the end bearing. It has to take alot of beating :) THAT and the motor power. That thing looks like a beast. So Its probably fine. But its all about what sort of tub size and shape you are going for
10:45 AM sensille: small, workpieces maybe up to 100x60mm
10:46 AM miss0r: in batches of what? 200? :D
10:46 AM miss0r: I think it will be fine
10:46 AM sensille: "a few" :)
10:46 AM miss0r: in that case. I'm sure it will be fine.
10:47 AM miss0r: also, it seems its ment for a belt drive. I would say it goes to reason that the end bearing is then meant to take a noticeable sideload. Perhaps that motor is quite suitable
10:47 AM sensille: so hard to decide when you have no idea what to expect :)
10:47 AM miss0r: yeah
10:48 AM sensille: good point. so i might not even need an extra set of bearings
10:48 AM miss0r: are you going to drive it with an h-bridge and a PWM drive signal?
10:48 AM miss0r: I guess you'll find out :)
10:49 AM sensille: at first i just want to drive it with my lab power supply
10:50 AM miss0r: Indeed
10:50 AM miss0r: anyway, I was just in the shop for a quick smoke, I'm off again :)
11:13 AM sensille: Loetmichel: do you know by any chance which t-nuts fit into the 6040 profile? it looks a bit too small to be standard
11:14 AM sensille: "Nut6 Typ I" might fit, but is a bit undersized
11:21 AM Loetmichel: no idea
11:21 AM Loetmichel: i made my own
11:22 AM sensille: i was afraid of that :)
11:23 AM sensille: from al?
11:24 AM roycroft: i would not make a t-nut out of aluminium
11:24 AM roycroft: make them out of steel, preferably steel that can be somewhat hardened, and distort the bottom of the thread after you cut it
11:25 AM sensille: i can't work with steel yet
11:26 AM sensille: but i want to use 12 or 15 of them to fix the spoilboard
11:26 AM Tom_L: JT-Cave, this thaw has already created a mess
12:22 PM _unreal_: making my inverter PCB so I can have working signals to the arduino for the laser ether grbl ctrler
12:24 PM gloops: https://www.ebay.co.uk/itm/Metal-lathe-3-Meter-Between-Centers/324492129388?
12:24 PM gloops: lot or iron there for £11
12:37 PM _unreal_: eheheh 11 euro's
12:37 PM _unreal_: granted moving cost's would be huge and repair
12:39 PM roycroft: not 11 euros
12:39 PM roycroft: 11 pounds
12:40 PM roycroft: the one smart thing the brits did was not adopt the euro
12:40 PM _unreal_: oh pounds
12:40 PM _unreal_: dont know what that translates to, to dollars regardless
12:41 PM _unreal_: when I get it all working I'm going to clean up the design files a bit
12:41 PM _unreal_: and post my designs on thingverse for this laser etcher
12:41 PM _unreal_: should be an other SMASH shit
12:41 PM roycroft: one pound sterling has been equivalent to roughly US$1.50 for a long time
12:42 PM _unreal_: one of my publications got half a mill downloads as I recall after 6 months
12:42 PM roycroft: i don't track it, but i use that as a ballpark figure
12:42 PM SpiritHorse: no it hasn't
12:42 PM SpiritHorse: GBP has fluctuated, wildly, like every major currency
12:42 PM SpiritHorse: unless you're one of those that thinks 1.22 is "close enough" to 1.50
12:42 PM roycroft: i did not say how roughly :)
12:43 PM roycroft: and yes, for quick calculation. $1.22 is close enough to $1.50
12:43 PM _unreal_: ugh. IRC mortal combat
12:43 PM SpiritHorse: hehehe
12:43 PM roycroft: as in getting a sense of cost
12:43 PM SpiritHorse: a 23% difference... "close enough"
12:43 PM SpiritHorse: good stuff
12:43 PM roycroft: if i'm going to actually buy something from the uk i check the current exchange rate
12:43 PM roycroft: yes, 23% difference is just fine for getting a rough idea
12:44 PM _unreal_: ARG.... HURRY.... hate waiting for PCB's to mill
12:44 PM _unreal_: such slow feed rates
12:44 PM SpiritHorse: hurry up and wait is more like it :>
12:44 PM _unreal_: I'm using .5 mm rasps
12:44 PM roycroft: there's "is this in the realm of being reasonable?" and "seems like it might work out - now it's time to crunch the numbers precisely"
12:44 PM _unreal_: tiny tiny tuny but never wear out
12:45 PM _unreal_: just soooo damn frail
12:45 PM _unreal_: cant tell ya how many I break
12:45 PM _unreal_: typically stupid shit too
12:45 PM _unreal_: My fav is turning on limits so I can back off of something only to forget
12:45 PM _unreal_: then try to zero the bit and CNAP
12:45 PM _unreal_: snap
12:45 PM roycroft: if i see something for sale in sterling, i multiply by 1.5 in my head and see if it makes sense
12:46 PM roycroft: it's harder to both keep track of needing to multply by 1.22 and to actually multiply by 1.22 in my head
12:46 PM _unreal_: if I was smart I should have started up the soldering iron
12:46 PM _unreal_: sigh
12:46 PM _unreal_: 1min left on the milling job
12:48 PM roycroft: i spent a lot of time yesterday routing the power cord from my bandsaw motor to where i think i'm going to mount the power switch, only to find the cord is a wee bit too short for where i expect i want to mount the switch
12:48 PM roycroft: there's another path for routing the power cord that i do not prefer, but is safe and would get me the extra length, so i may spend a lot of time today redoing that
12:49 PM roycroft: but i'm not sure if i need to reroute or not, and i need to use my bandsaw to finish refurbising the bandsaw
01:25 PM PasstScho: Hi! I'm wondering if someone can help me finding the right mesacard setup for my machine... It is a 5 axis VMC with 2 axis tool changer and atc spindle -> here is an overview http://188.110.50.33/machine_setup_overview.pdf (gpios not drawn but quite some necessary).
01:27 PM PasstScho: I'm having a 5i20 already but i think it will not be enought for 8stepgens, 6 encoder with index + mpg wheel and various gpios. All signals should have isolation from computer.
01:51 PM miss0r: 'evening
01:52 PM Jymmm: miss0r: hi
01:52 PM miss0r: hello Jymmm, long time no see
01:56 PM Jymmm: miss0r: Life just been in the way
01:56 PM miss0r: yup
01:56 PM zeeshan: https://photos.app.goo.gl/6ox2Tp4icZVe8ySd9
01:56 PM zeeshan: any way to hold this without making special vise jaws? :D
01:57 PM zeeshan: i just need to remove the holding stock from the opposite side
01:57 PM miss0r: a powerfull magnetic chuck?
01:58 PM zeeshan: im trying to use a regular milling vise
01:58 PM zeeshan: the only thing i can come up is a swivel in a vise jaw
01:59 PM miss0r: well.. thats not ideal. A slight bump on one direction will dislodge it then
01:59 PM Tom_L: zeeshan, double back tape?
01:59 PM Tom_L: superglue
02:00 PM miss0r: that is doable too, yeah
02:00 PM Tom_L: i usually just make softjaws to fit
02:01 PM zeeshan: i just added another image
02:01 PM JT-Cave: yea it's just starting to get melted here
02:01 PM W1N9Zr0: got b-blocks? you could squeeze it on the opposite corners with them
02:01 PM W1N9Zr0: *v-blocks
02:01 PM zeeshan: problem is i have 8 of pairs to make and ofcourse each pair has has a different frigging angle
02:01 PM miss0r: zeeshan: That last ċicture of yours seems ALOT more complicated than just milling some softjaws
02:01 PM zeeshan: i just uploaded another image showing the concept....
02:02 PM Tom_L: but the straight end against some shorter dowel pins and tape it
02:02 PM zeeshan: yes but ill need to machine 4 sets of soft jaws
02:02 PM Tom_L: the pins will help keep it from shifting
02:02 PM Tom_L: stuff em on a belt sander :)
02:02 PM zeeshan: haha
02:02 PM miss0r: hehe
02:03 PM miss0r: zeeshan: Why 4 sets?
02:03 PM Tom_L: what? you can't hold +- .001 on a sander????
02:03 PM zeeshan: v-blocks hmm i don't see it
02:03 PM Tom_L: me either
02:03 PM miss0r: Tom_L: I assume you are referring to inches :P if you are talking in mm, you'd have to sneak up on it a bit :D
02:04 PM zeeshan: i was thinking i could use a couple of my balls bearings with flats on them
02:04 PM Tom_L: meh
02:04 PM zeeshan: but that was a failure haha
02:04 PM miss0r: Yeah, I don't see how that would work either.
02:04 PM Tom_L: just stick them to a plate with a couple or three dowel pins
02:04 PM miss0r: Tom_L: That would absolutly work.
02:05 PM zeeshan: with double sided tape?
02:05 PM Tom_L: if you're just shaving off the back position doesn't matter
02:05 PM miss0r: use super glue, and just heat it off afterwards
02:05 PM W1N9Zr0: https://i.imgur.com/n1kZCgw.png v-blocks, take your pick on orientation
02:05 PM zeeshan: yes thats all im doing, facing the 3/16 grip stock
02:05 PM Tom_L: zeeshan, yeah with the pins to push against with the shell mill
02:05 PM miss0r: W1N9Zr0: how would you even start to compress that? :D
02:06 PM htasta: PasstScho: You should ask here as I think you need a combination of cards: https://forum.linuxcnc.org/27-driver-boards
02:06 PM Tom_L: don't take 3/16 deep cuts though
02:06 PM W1N9Zr0: if you have through-holes, you could clear around holes while holding grip stock, then bolt it down to something and clear the rest
02:06 PM Tom_L: you're making it too hard
02:06 PM miss0r: zeeshan: How big is the part and what is it made of?
02:06 PM zeeshan: aluminum, about 6x9
02:07 PM zeeshan: "
02:07 PM miss0r: hehe
02:07 PM miss0r: I would just super glue that directly to a support plate and remove the top
02:07 PM miss0r: I probably wouldn't even use dowels
02:07 PM zeeshan: i've never done the double side tape + glue method
02:07 PM zeeshan: i know it works, just makes me uncomfortable
02:07 PM miss0r: I wouldn't even bother with the tape.
02:07 PM Tom_L: do what suits you best then
02:08 PM miss0r: I know it takes a bit of cleaning afterwards, but I usualy just heat the part with a hot air gun afterwards, till it just drops off
02:08 PM miss0r: regular superglue lets go at around 100c
02:08 PM zeeshan: tom_l don't hate :D
02:08 PM PasstScho: htasta, Ok, thanks! I think so, too
02:08 PM zeeshan: i like overthinking about odd shapes like this
02:08 PM zeeshan: cause gripping this stuff always kicks my ass
02:08 PM Tom_L: no matter to me. there's always more than one way to approach something
02:09 PM zeeshan: i've always done soft jaws
02:09 PM Tom_L: then do softjaws
02:09 PM zeeshan: its the 4 different pairs that forced me to look at alternatives
02:09 PM _unreal_: My signal inverter is working
02:09 PM _unreal_: but just found an other connection that is not working WTF
02:09 PM zeeshan: wait a sec............
02:10 PM _unreal_: issues with a poor quality PCB
02:10 PM zeeshan: can't i just make two half circles in the vise jaw and drop some pins in??
02:10 PM miss0r: why is it you'd need four different pairs?
02:10 PM _unreal_: poor coper clad bond to the FR4
02:10 PM _unreal_: :(
02:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/SoftJaws1.jpg
02:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/SoftJaws3.jpg
02:10 PM zeeshan: theres 2 of these parts miss0r
02:10 PM zeeshan: and then 6 more , each has a different angle on it
02:10 PM Tom_L: if you think the end shape is thick enough without warpage from the jaws
02:10 PM zeeshan: er 3 more pairs i mean
02:10 PM miss0r: lol :D
02:11 PM zeeshan: its 1" thick
02:11 PM zeeshan: its not going to warp
02:11 PM zeeshan: those are some sexy soft jaws
02:11 PM Tom_L: all you need is to change 1 jaw per part
02:11 PM Tom_L: the one side is flat
02:12 PM miss0r: zeeshan: its easy to end up with some complicated jaws: https://imgur.com/a/nuqXalR
02:12 PM zeeshan: good point
02:12 PM Tom_L: hell if you're good, you could get more than one part from a single set
02:12 PM miss0r: indeed
02:12 PM Tom_L: just slide it over a bit
02:12 PM zeeshan: miss0r... were you using those slots w/ pins?
02:12 PM Tom_L: now let's see just how good ya are !
02:13 PM miss0r: jo.. thats the outline of some cooling fins on a design on mine, so I could hold on to the back :D
02:13 PM miss0r: s/jo/no
02:13 PM miss0r: Tom_L: No pressure though :D
02:13 PM zeeshan: i saw a visejaw similar to what you're showing there
02:13 PM Tom_L: never
02:13 PM zeeshan: but it had pins that stack inside slots...
02:14 PM zeeshan: they could be adjusted for odd shaped parts
02:14 PM Tom_L: who cares what they look like as long as they fit the profile
02:14 PM JT-Shop: https://gnipsel.com/images/wood-working/dust-collection/dust-manifold-03.jpg
02:14 PM Tom_L: fancy
02:14 PM zeeshan: nice JT
02:14 PM miss0r: another idea, while we're spitballing here: You *could* just use three seprate "open" vices.
02:15 PM miss0r: bah. I'm still loading that image from JT. I feel like I'm back in the dialup days here
02:15 PM Tom_L: stand em on end with a square block and bandsaw em :D
02:15 PM zeeshan: haha
02:15 PM Tom_L: no?
02:15 PM zeeshan: my bandsaw would cut them with a 3/8" taper
02:15 PM zeeshan: ok maybe not 3/8
02:15 PM zeeshan: but like 1/32" haha
02:16 PM miss0r: and you sound like that is *not* what you wanted? :S
02:16 PM miss0r: looking good, jt
02:16 PM zeeshan: i think what we're concluding is I need to buy an EDM
02:16 PM miss0r: I have one you can buy cheaply :)
02:16 PM miss0r: but I think shipping it "overthere" will cost a minor fortune
02:22 PM JT-Shop: I'm even slower being throttled till the end of the month
02:23 PM miss0r: sucks
02:23 PM miss0r: My issue is that I am connected through the 4G network. The copper lines "out here" sucks
02:23 PM Tom_L: JT-Shop, is irc like reading txt over a 300baud modem?
02:23 PM JT-Shop: zeeshan, I do crazy shapes all the time without any special vice jaws
02:24 PM JT-Shop: well not quite that slow
02:24 PM Tom_L: :)
02:24 PM Tom_L: i never could quite outread a 1200baud one
02:24 PM JT-Shop: zeeshan, if those are through holes just drill them while the plate is square then mount the part to a fixture plate and mill the profile
02:26 PM Tom_L: aparently he's got 3/16" excess to shave off the back
02:26 PM JT-Shop: machine to thickness before doing the profile
02:27 PM JT-Shop: all the parts I made last week were strange shapes
02:27 PM * JT-Shop goes to clean up on aisle 3
02:28 PM Tom_L: or buy the right material to start with
02:29 PM miss0r: damn. I remember seeing this guy doing a engine head resurface by dragging it across a concrete sidewalk tile... Couldn't find the video though. Was about to suggest that :D
02:34 PM JT-Shop: LOL
02:34 PM JavaBean: you know... i worry that the concrete wouldn't be flat enough for that
02:34 PM miss0r: oh realy? :D
02:35 PM Tom_L: @ 1:13 pm
02:36 PM PasstScho: still here
02:36 PM Tom_L: jt can help you
02:37 PM JT-Shop2: PasstScho: what do you need?
02:38 PM Tom_L: It is a 5 axis VMC with 2 axis tool changer and atc spindle -> here is an overview
02:38 PM PasstScho: <PasstScho> Hi! I'm wondering if someone can help me finding the right mesacard setup for my machine... It is a 5 axis VMC with 2 axis tool changer and atc spindle -> here is an overview http://188.110.50.33/machine_setup_overview.pdf (gpios not drawn but quite some necessary).
02:38 PM PasstScho: <PasstScho> I'm having a 5i20 already but i think it will not be enought for 8stepgens, 6 encoder with index + mpg wheel and various gpios. All signals should have isolation from computer.
02:38 PM Tom_L: add a sserial card for sloer io like limits etc
02:38 PM Tom_L: slower*
02:40 PM Tom_L: http://store.mesanet.com/index.php?route=product/product&product_id=123
02:40 PM JT-Shop2: hmm 8 stepgens and 6 encoders, yeah the 5i20 would be the greatest place to start
02:40 PM PasstScho: yep, but I guess that's gonna be the easy part. I don't have a good plan which cards to use for the many stepgen & encoder inputs
02:40 PM JT-Shop2: mesaus.com
02:40 PM PasstScho: *i mean the IOs over serial
02:40 PM JT-Shop2: let me go to the other shop and see
02:42 PM PasstScho: hostmot2 driver does not seem to support enough modules on 5i20, so i'm gonna need a second one... but so many options and none really seems to fit good
02:44 PM JT-Shop: 7i88 will work for up to 8 step/dir
02:44 PM JT-Shop: 7i89 is 8 channel encoder
02:45 PM JT-Shop: for I/O you could use 7i69
02:46 PM JT-Shop: the above two use cards like 5i25, 6i25, 7i92M and 7i80DB
02:46 PM Tom_L: is it isolated?
02:46 PM Tom_L: looks like it should be
02:47 PM Tom_L: or at least 5v ttl
02:47 PM JT-Shop: I don't see a 5i25_7i88_7i89.bit but that don't mean Peter doesn't have one
02:48 PM JT-Shop: I know for sure this pc does not have the latest firmwares
02:48 PM PasstScho: where to find a list of firmwares?
02:49 PM zeeshan: miss0r i can't wait to get access to starlink :D
02:49 PM PasstScho: http://linuxcnc.org/docs/html/drivers/hostmot2.html#_configurations <== im always checking this list but i guess it is outdated?
02:49 PM JT-Shop: store.mesanet.com look for the 5i25 and support
02:49 PM Tom_L: in the card specification -> support software
02:50 PM JT-Shop: hostmot2 is the LinuxCNC interface not the firmware that is flashed to the 5i25 etc
02:50 PM Tom_L: linuxcnc.org is usually lagging behind a little on the very latest
02:50 PM Tom_L: for supported cards
02:50 PM JT-Shop: http://www.mesanet.com/software/parallel/5i25.zip
02:51 PM zeeshan: @JT-shop i am on your website, i remember you building a log splitter
02:51 PM zeeshan: still have that on there?
02:51 PM JT-Shop: should be, engine backfired yesterday a blew up the bendix
02:52 PM zeeshan: bendix?
02:52 PM zeeshan: starter?
02:53 PM JT-Shop: aye
02:53 PM zeeshan: i cant find it the link :{
02:53 PM JT-Shop: lol me neither
02:53 PM zeeshan: i remember it was a good design
02:53 PM zeeshan: and saying why don't you split the wood by hand haha
02:53 PM zeeshan: now I NEED one haha
02:53 PM JT-Shop: https://gnipsel.com/files/splitter/
02:54 PM zeeshan: look at that, you have is designed in solidworks :D
02:54 PM JT-Shop: https://gnipsel.com/images/splitter/
02:54 PM zeeshan: do you mind if go off your design?
02:54 PM JT-Shop: help yourself
02:54 PM JT-Shop: use a better engine lol
02:55 PM JT-Shop: I only used the 190cc Intek because I had a pile of them on the shelf
02:55 PM PasstScho: i'm checking the manuals of those cards to get an idea...
02:55 PM JT-Shop: one of few automatics I built for Briggs at the end of the assembly line so we got finished engines to test with
02:56 PM zeeshan: i have an old lawnmower that i can steal a briggs from
02:56 PM * JT-Shop wanders back to the other shop to clean up
02:56 PM PasstScho: both cards don't seem to be isolated but I guess I can use the isolator card between?
02:56 PM JT-Shop: might get a smaller pump if the engine is small
02:57 PM JT-Shop: isolated from what?
02:57 PM PasstScho: galvanically isolated from computer
02:58 PM zeeshan: https://gnipsel.com/files/splitter/Photos/IMG_0671.JPG
02:58 PM zeeshan: BEEFY
02:58 PM Tom_L: zeeshan, this is JT we're taling about here
02:59 PM PasstScho: theres a 5i25_7i88x2.bit file so i could use the 5i25 with this 7i88 card and connect 7i89 + serial gpio expander & serial mpg cards to my 5i20?
03:00 PM zeeshan: it's no harbor freight log splitter that's for sure
03:00 PM Tom_L: hah
03:00 PM JT-Shop: I've never used a 5i25 and 5i20 at the same time, that's a question for pcw who is not here at the moment
03:01 PM PasstScho: hm, aren't those cards independently useable in one computer?
03:01 PM JT-Shop: dunno, never tried it
03:02 PM Tom_L: in theory
03:02 PM JT-Shop: 7i92M might be better it only has an Ethernet cable to the pc
03:02 PM zeeshan: jeez you even built the sump too
03:02 PM JT-Shop: aye
03:02 PM JT-Shop: clean the metal good when welding tanks or you learn new cuss words
03:03 PM Tom_L: at our age there are still new ones?
03:03 PM PasstScho: 5i23 could replace 5i20 and 5i25
03:03 PM zeeshan: i hate welding the last 1/4" of an enclosed tank
03:03 PM zeeshan: i'll prolly just by the hydraulic powerpack
03:03 PM zeeshan: *buy
03:04 PM zeeshan: the log splitter I want to build because I used a friends princess auto one and it's garbage
03:04 PM zeeshan: princess auto is the canadian harbor freight
03:04 PM Tom_L: i was gonna say.. that sounded familiar from another friend up there
03:09 PM JT-Shop2: 5i23 is just a bigger 5i20
03:10 PM PasstScho: 5i23 has enough gates for 8stepgen & 8encoders, so i could connect 7i88, 7i89 & serial cards + io-expander?
03:11 PM PasstScho: and isolators... hm now i get it... it's just getting a lot stuff ;)
03:11 PM Tom_L: if you have an extra sserial on it yes
03:12 PM JT-Shop2: no, the 5i23 is for 50 pin cards like the 7i33ta
03:12 PM JT-Shop2: 7i47s works with 5i20 or 5i23
03:13 PM Tom_L: does he need the analog for spindle?
03:13 PM Tom_L: the plain 7i47 would give a couple more io
03:13 PM PasstScho: ah damn there's 25 & 50 pin!
03:13 PM Tom_L: heh
03:13 PM PasstScho: spindle needs pulse too, no analog
03:14 PM JT-Shop2: DB25 cards can use Smart Serial cards for more I/O
03:17 PM PasstScho: starting an excel sheet now or i'll never get it all in my brain xD
03:17 PM Tom_L: the 7i47 (s) will do sserial
03:19 PM JT-Shop2: I've never messed with one even though I have one in stock
03:19 PM Tom_L: i've tested it on mine
03:19 PM JT-Shop2: cool
03:19 PM * JT-Shop2 can't seem to find a starting point for cleaning up the big shop
03:20 PM PasstScho: hm, do i get this right... those smart serial cards can be read serially so don't need the host card's fpga for stepgen & encoder?
03:24 PM JT-Shop2: when you plug a smart serial card in it is auto magically discovered
03:25 PM W1N9Zr0: i have a similar question actually, are encoders and stepgens on sserial usable for main axis or spindle? or are they only good for less realtime stuff like pendants, and accessories like toolchanger?
03:26 PM internut: I think you could encode the position of the spindle, but, why?
03:26 PM PasstScho: W1N9Zr0, 7i88 is for differential step/dir so it should do time critical stuff
03:26 PM internut: car engines do it
03:26 PM Tom_L: W1N9Zr0, slower stuff like switches and pendants only
03:26 PM JT-Shop2: do you see any smart serial cards with stepgens or encoder?
03:27 PM Tom_L: i doubt you will
03:27 PM W1N9Zr0: there's a pendant board that has en encoder interface
03:27 PM PasstScho: wait and smart serial != 25pin damn xD
03:27 PM Tom_L: that encoder is for the pendant MPG
03:27 PM Tom_L: W1N9Zr0,
03:27 PM W1N9Zr0: so sserial is polled at a slower rate than the on-board stepgen and encoder right?
03:28 PM Tom_L: basically yes
03:28 PM Tom_L: dunno about polled slower but it's a slower interface
03:28 PM Tom_L: don't use it for timing critical things
03:29 PM Tom_L: an encoder @6krpm isn't the same as a MPG on a pendant
03:30 PM JT-Shop2: the pendant encoder is for single ended mpg
03:46 PM PasstScho: JT-Shop2, http://188.110.50.33/mesa_card_setup.pdf <== now if i got it right - might this work?
03:49 PM Tom_L: he can't look.. his data is out for the month
03:50 PM htasta: hahahaahhaha
03:50 PM Tom_L: seems like alot of extra cards to me but i'm not familiar with all of them
03:50 PM PasstScho: damn he must be in germany xD
03:50 PM Tom_L: middle of nowhere usa
03:51 PM Tom_L: his new cellphone ate all his wifi and he didn't know it
03:51 PM JT-Shop2: PasstScho: I'm completely out of data and keep getting popups from the sat saying stop your out of data
03:52 PM JT-Shop2: it might open in a while...
03:52 PM PasstScho: ok, thanks anyways for your help!
03:52 PM Tom_L: i had that happen once on my cable connection but they never shut me down, just complained alot
03:53 PM Tom_L: PasstScho, what is tnat 2nd card?
03:53 PM Tom_L: first one a 6i25?
03:54 PM PasstScho: JT-Shop2, i can write it... i'd connect a 7i98 to an extra lan card and it's three 25 connectors get 7i88 stepgen, 7i89 encoder & 7i74 serial with 7i73 mpg & 7i64 io card
03:54 PM PasstScho: Tom_L, main one is 7i98
03:54 PM Tom_L: you don't like the 50pin cards?
03:55 PM Tom_L: that might be alot to drive off an ethernet card. that may be a PCW question
03:55 PM Tom_L: it may be fine, i'm just not familiar with that card
03:55 PM JT-Shop2: yea and check to see if the 7i98 has firmware to support those cards
03:56 PM PasstScho: i do but only 5i23 supports enought modules and they also need a lot of dougther cards
03:56 PM Tom_L: you might be better off with a pci pcie mesa card as the 1st one
03:57 PM Tom_L: i'd talk to PCW before you commit
03:57 PM JT-Shop2: you might look at a 7i76 and 7i78 and the 7i73 can connect to the 7i76
03:57 PM PasstScho: Tom_L, i will check again with 5i23 but i think it will be more because of separate isolation cards
03:57 PM Tom_L: lately you might find him quicker on the forum
03:58 PM PasstScho: i will ask pcw when i checked with 5i23
03:58 PM Tom_L: there's definitely more than one way to go
03:58 PM PasstScho: custom made cards for 5i23 would also be an option but i don't want too many projects...
03:58 PM Tom_L: i know ethernet takes a big chunk out of the fpga but timing wise it may work fine, i dunno
03:58 PM JT-Shop2: pcw has been active on the forum lately
04:01 PM * JT-Shop2 might even have some Mesa cards if UPS can find his house Monday
04:01 PM Tom_L: looks like i'll be goin down some muddy county roads this week.
04:02 PM Tom_L: i knew it wouldn't pay to wash the car
04:03 PM PasstScho: JT-Shop2, not sure if shipping from US to Germany is a good idea... I think I need to check a local dealer first
04:05 PM JT-Shop2: shipping is the big issue during the pandemic, I have a package to Austria that went to the Bahamas and now it's bouncing around the US
04:07 PM Tom_L: collecting all the germs it possibly can
04:07 PM PasstScho: uff I don't want to hear that xD somehow I think my setup will be so special that i need stuff from US...
04:08 PM PasstScho: which shipping company did you use?
04:08 PM CaptHindsight: sounds lie a Disney story, package takes a vacation
04:08 PM JT-Shop2: USPS
04:08 PM CaptHindsight: lie/like
04:08 PM Tom_L: CaptHindsight, cast away
04:08 PM PasstScho: usually ups are the best (and most expensive)... not a good sign ;)
04:09 PM JT-Shop2: PasstScho: http://store.mesanet.com/international-dealers
04:09 PM PasstScho: i ordered big stuff from china with cheaper companys and that went fine
04:09 PM JT-Shop2: that's the international dealers for Mesa
04:10 PM PasstScho: thanks, there are some in my area
04:14 PM CaptHindsight is now known as CaptBattery
04:19 PM PasstScho: still checking but i prefer the 7i98 version. Cable length and isolation is included cheap. With 5i25 and 5i52 i'd have to use isolators and deal with 3x50pin flat cables from the computer :-/
04:19 PM PasstScho: gotta ask pcw these days...
04:23 PM JT-Shop2: try the forum
04:30 PM PasstScho: yep, need to write & ask a bit more - but going to sleep now
04:31 PM PasstScho: Thank you very much for your help!
04:31 PM Tom_L: aim to please
04:32 PM JT-Shop2: yw
04:33 PM PasstScho: ah one last question before i sleep... does anyone know if delta asda-b2 servo controls can be position controlled by serial interface? (not time critical, just tool changer) I know A2 series can, but B2 does not seem to...?
04:41 PM JT-Shop2: never messed with one
04:46 PM * JT-Shop2 found the MIA pop rivet tool and in the process recovered 24 square feet of floor
04:48 PM PasstScho: gn8
04:57 PM CaptBattery: https://www.botfactory.co/page/products
04:57 PM CaptBattery: cheap CNC router frame with HP inkjet cartridges for printing PCB's
05:03 PM XXCoder: "cheap" "get a quote now"
05:11 PM roycroft: well i think i've partially disassembled my bandsaw for the last time, other than some tweaking of the fence and table
05:11 PM roycroft: the last two parts are partially in paint
05:12 PM * roycroft is so ready to move on from that project
05:14 PM roycroft: i'm fairly certain the channel tired of hearing about it as well
05:18 PM XXCoder: lol
05:18 PM XXCoder: nice to see that youre finishing it up though
05:19 PM JT-Shop2: roycroft: did you see the final dust manifold photo
05:19 PM XXCoder: i dont think i saw that either?
05:20 PM JT-Shop2: https://gnipsel.com/images/wood-working/dust-collection/dust-manifold-03.jpg
05:21 PM XXCoder: nice
05:21 PM XXCoder: i guess use clips on those red and green tabs?
05:21 PM roycroft: no, i didn't see it
05:22 PM roycroft: nice
05:22 PM roycroft: the end caps are on and hoses connected now
05:22 PM roycroft: that looks pretty finished
05:22 PM JT-Shop2: red is blocked of and green is open
05:22 PM JT-Shop2: makes it easy to spot which tool is connected
05:23 PM XXCoder: ahh nice indeed
05:23 PM roycroft: i don't like all that flex hose, but it looks like the runs are fairly short, so it will probably work ok
05:23 PM JT-Shop2: I move the green blast gate from tool to tool
05:23 PM roycroft: if not you can always put some sections of rigid pipe in
05:24 PM JT-Shop2: I move things around based on what I'm doing so flex is a must
05:24 PM JT-Shop2: everything is on wheels in this shop
05:24 PM roycroft: i'm using flex hose myself now, so there's that
05:24 PM roycroft: yeah, all my machines are mobile to
05:24 PM roycroft: i just added a cyclone pre-colletor
05:25 PM JT-Shop2: I have a small cyclone that I used with the table saw
05:25 PM roycroft: my plan is to pull rigid ducting from that overhead, split it in two directions, and then add flex drops down to the machines
05:25 PM roycroft: the overhead part will be 5", and i'll drop to 4" at each machine
05:26 PM XXCoder: cyclpones is awesome
05:26 PM roycroft: https://www.woodcraft.com/products/oneida-air-systems-molded-super-dust-deputy-cyclone
05:26 PM roycroft: that's the one i got
05:27 PM roycroft: woodcraft had it on sale for $129 a couple months ago, bundled with some 4" adapters, so i just got it, got a 55 gallon barrel to park it on and spliced it into my existing 4" system
05:28 PM JT-Shop2: https://www.woodcraft.com/products/oneida-air-systems-4-super-dust-deputy-deluxe
05:28 PM roycroft: my dust collector has a 6" inlet, so when i'm ready to go with the rigid ducting, i can easily hook up the dust collector side with a piece fo 6" flex ducting
05:28 PM roycroft: and since there will be no chips in that segment, flex ducting will be fine
05:29 PM JT-Shop2: I have that one, need to have an outside vacuum source so it's quieter
05:29 PM roycroft: yeah, i parked my dust collector in the lean-to next to my garage shop to save space and, especially, noise
05:29 PM roycroft: that's why i really need the rigid ducting - i have to go about 15' before i get to my first drop
05:30 PM roycroft: if i just replace that section with rigid i'm sure it will be a big win
05:30 PM JT-Shop2: I'm not there yet, need to put the air compressor and dust collector under the lean too
05:30 PM roycroft: my compressor has been living in the lean to for years
05:30 PM roycroft: also to keep things quiet
05:30 PM roycroft: i must say, though, the maintenance i did on it a couple weeks ago was the biggest win
05:31 PM roycroft: getting the tank emptied of all the water really helped - it doesn't cycle nearly as much nw
05:31 PM roycroft: and there was also a small air leak in the water filter inside my shop
05:31 PM roycroft: that made more noise than i realised, and also contributed to excessive cycling
05:31 PM roycroft: i replaced the filter, and it is so quite now
05:32 PM JT-Shop2: nice
05:32 PM JT-Shop2: I don't use much air out in this shop, the machine shop air compressor is in the garage as well as the rotary phase converter
05:32 PM roycroft: i was going to get the 4" dust deputy, but when that 5"/6" one went on sale it seemed a better thing to do, especially since my dust collector has a 6" inlet
05:33 PM roycroft: i get a fair amount of sawdust accumulation in my tablesaw
05:34 PM roycroft: the previous owner said he did not, but he had a 5" duct connected to it at his shop, and a much shorter run to the dust collector
05:34 PM roycroft: i have to manually empty my table saw base every 2-3 months
05:35 PM roycroft: manually meaning i put a shop vac hose on my duct collector line and stick it inside the cabinet to suck all the sawdust out
05:35 PM roycroft: i'd rather not have to do that
05:37 PM roycroft: i expect that in my situation it's more the long run of 4" flex hose that's the issue, and even if i just replaced 15' of that with 4" rigid duct it would work a lot better
05:45 PM * JT-Shop2 recovers 16 square feet of floor and calls it a day... save some for tomorrow night
06:01 PM JavaBean: 16square feet??? what tool did you get rid of??? can I have it?
06:03 PM Tom_L: prepare yourself... https://www.nytimes.com/2021/02/20/us/texas-storm-electric-bills.html
06:03 PM JT-Cave: cleaned a spot on the shelves for some hard wood that was on saw horses
06:04 PM roycroft: i've already read and heard all about that
06:04 PM XXCoder: tom yeah glad I live at region with far more reliable power
06:04 PM roycroft: texas is already on the verge of turning blue
06:04 PM roycroft: this storm may push it over the top, and it may finally join the civilised world
06:06 PM Tom_L: i think it affects the whole grid
06:06 PM roycroft: the issue is that texas has its own grid that is isolated from the rest of the country
06:06 PM roycroft: and is therefore not subject to federal regulation
06:07 PM Tom_L: i think we got a similar notice and we're on the grid
06:07 PM roycroft: texas completely deregulated its power utilities a few years ago
06:07 PM roycroft: and this is the result
06:07 PM Tom_L: same with natural gas
06:07 PM roycroft: yes
06:08 PM XXCoder: roy not completely
06:08 PM XXCoder: thats why they are calling for.... more deregulation
06:08 PM XXCoder: its like seeing leaky tire and asking for drill to add more holes to see if it can hold air now
06:08 PM * roycroft is fortunate to live in a city that has one of the oldest public power/water utilities in the nation, and that utility actually serves it ratepayers instead of raping them
06:09 PM roycroft: eweb has been around since 1911
06:11 PM zeeshan: one thing i know about usa is when shit goes bad, the people come together and make sure things improve
06:11 PM roycroft: we have some of the cheapest electric rates in the nation and more than 95% of our power is produced by non-carbon emitting sources
06:11 PM JavaBean: only additional "deregulation" i have heard about is them trying to tell the EPA to get fu$#@$#
06:11 PM roycroft: then you know nothing about the usa
06:11 PM zeeshan: roycroft what state?
06:11 PM roycroft: because that is a blanket statement that is patently false in many parts of the nation
06:11 PM roycroft: i'm in oregon
06:12 PM roycroft: where we're blessed to have a lot of hydropower
06:12 PM JT-Cave: zeeshan, is trg still around?
06:12 PM zeeshan: i look at the usa as one entity :)
06:12 PM XXCoder: hey fellow COW state guy
06:12 PM zeeshan: yes
06:12 PM roycroft: you could not be more wrong about that, zeeshan
06:12 PM JT-Cave: I forget where he is
06:12 PM zeeshan: NJ
06:12 PM roycroft: if you choose willful ignorance that is your perogative, certainly
06:12 PM roycroft: but it won't benefit you
06:12 PM JT-Cave: no, the irc channel
06:12 PM zeeshan: oh, i don't think hes there anymore haha
06:13 PM Tom_L: roycroft, as an ousider looking in i can see how that happens
06:13 PM JT-Cave: ah ok
06:13 PM JT-Cave: looks like it's chow time here
06:13 PM zeeshan: https://www.instagram.com/trgcoating/?hl=en
06:13 PM zeeshan: he does some really nice work
06:14 PM JT-Cave: yes he does
06:14 PM Tom_L: fwiw, dell bought emc and isn't using the name anymore
06:14 PM roycroft: i'm going to work on my bandsaw fence a bit more, i think
06:14 PM zeeshan: roycroft: i try to think positive
06:14 PM roycroft: the last part of the installation is not going to be fun
06:14 PM XXCoder: nd belive that companies will for reals prep for cold?
06:14 PM roycroft: the main fence itself is cast iron, and hollow with supporting ribs
06:14 PM XXCoder: they didnt in 2008. they didnt in 2011. and they didnt in 2021
06:15 PM zeeshan: hope they will now :D
06:15 PM roycroft: the end of the fence has a plasti bumper that sits on top of a rail mounted to the real of the table
06:15 PM zeeshan: frozen pipes suck.
06:15 PM XXCoder: you can hope. ill just push for actual regulation
06:15 PM roycroft: but my table is not deep enough for the real rail to line up with that knob, so i'm going to have to install a mounting plate for the knob inside the fence
06:16 PM roycroft: which, being rough cast iron, is a mess on the inside
06:16 PM zeeshan: xxcoder: totally agree, building codes make a difference
06:16 PM roycroft: i don't think that texas will fix the power grid soon
06:16 PM XXCoder: im not talking about building codes.
06:16 PM roycroft: but if the state starts turning blue, they'll probably end up voting to connect to the eastern and/or western grid, and subject themselves to federal regulation
06:17 PM XXCoder: im talking about regulations on power centers, like prepping for cold, supplies to last for a week even if everything is shut down, etc
06:17 PM roycroft: at which time they'll start fixing the grid
06:17 PM JT-Cave: zeeshan, geez I forget his first name is it Tony?
06:17 PM roycroft: but as long as folks like abbott are in charge, nothing is going to get done
06:17 PM zeeshan: tom
06:17 PM XXCoder: and yes, actually installing heaters on windmills.
06:17 PM zeeshan: its been a while :D
06:17 PM JT-Cave: ah yes
06:17 PM roycroft: which is why i think this storm may be what turns the state blue
06:18 PM roycroft: the wind generators account for only about 10% of texas' electricity
06:18 PM XXCoder: 12% but yeah
06:18 PM zeeshan: XXCoder building codes also apply to industry.
06:18 PM roycroft: most of it is natural gas plants, which also froze up
06:18 PM XXCoder: zee yes but thats not my point.
06:18 PM JT-Cave: I don't do instragram so I'll just text him
06:18 PM roycroft: not in texas, for the most part :)
06:18 PM zeeshan: he has whatsapp too
06:18 PM roycroft: they don't have much in the way of building codes or zoning in texas to begin with
06:19 PM roycroft: there are highly toxic, mostly unregulated chemical plants directly adjacent to elementary schools in texas
06:19 PM roycroft: and the state does not inspect them at all
06:19 PM zeeshan: i heard there was stuff like that happening in Louisiana too
06:19 PM roycroft: yes
06:20 PM roycroft: but not here
06:20 PM roycroft: nor in most of this country
06:20 PM zeeshan: There are some issues in the south that hopefully will get resolved
06:20 PM roycroft: this is why making blanket generalizations about the usa does not serve one well
06:20 PM zeeshan: cmon man
06:20 PM roycroft: every state is different
06:20 PM zeeshan: most of the USA is pretty good
06:20 PM zeeshan: some southern states are kind of in the 80s still
06:20 PM roycroft: most of the usa by population
06:20 PM roycroft: by area, i'm not so sure
06:21 PM zeeshan: but that's not all of usa right
06:21 PM roycroft: and you mean the 1880s
06:21 PM zeeshan: haha
06:21 PM zeeshan: you know what's kind of interesting
06:21 PM Tom_L: living in oregon roycroft how do you seem to know so much about texas?
06:21 PM zeeshan: so many companies moved out of the california cause their regulations are so strict
06:21 PM zeeshan: they mostly moved to texas lol
06:22 PM zeeshan: i wonder what is going through their minds
06:22 PM roycroft: less than a month ago a black sheriff's deputy who died in louisiana was denied a graveyard plot because the rules at that graveyard were that only white people could be buried there
06:22 PM zeeshan: roycroft yea thats really backwards thinking
06:22 PM XXCoder: zee I wonder what they think of texas now
06:22 PM zeeshan: people are people
06:22 PM roycroft: i've been to texas multiple times, i know people who live in texas, and i am fairly aware of current events
06:23 PM zeeshan: when i was in wyoming
06:23 PM zeeshan: i felt like an alien haha
06:23 PM roycroft: i liked wyoming when i visited there
06:23 PM roycroft: it's a beautiful state
06:23 PM zeeshan: its beautiful
06:23 PM zeeshan: absolutely gorgeous.
06:23 PM roycroft: i tried to blend in, and felt welcomed there
06:23 PM roycroft: but that was back when my hair was shorter
06:23 PM roycroft: and i'm white
06:23 PM zeeshan: the west end of south dakota is nice too
06:24 PM zeeshan: can't believe there's actual cowboys haha
06:24 PM zeeshan: roy i totally understand that every state is different, i definitely feel/see it when driving through
06:24 PM roycroft: i should probably head back to the shop to figure out how to remodel the fence
06:25 PM zeeshan: but working with the contractors on site, boy they are really hard working
06:25 PM roycroft: i'm leaning towards milling out the appropriate section so it is square and straight, and drilling/tapping the insert that holds the pad
06:25 PM roycroft: vs. trying to weld it in
06:25 PM roycroft: since the fence is cast iron, i'm not sure i want to have a go at welding on it
06:26 PM roycroft: i've welded cast iron before
06:26 PM zeeshan: it's not too bad, but i would avoid it
06:26 PM roycroft: always cast iron to cast iron, though, never cast iron to steel
06:26 PM roycroft: four drilled and tapped holes would do the trick, and would look fine
06:26 PM zeeshan: this is a fence for a vertical bandsaw?
06:27 PM roycroft: yes
06:27 PM roycroft: this is a wood bandsaw, but there are fences for metal bandsaws as well
06:27 PM roycroft: although i think they're much more common on wood bandsaws
06:30 PM * roycroft notes that the biden administration has already agreed to help texans pay their power bills, amongst the other help it's providing, and that the previous administration denied 40% of fema claims from the wildfires, claiming people did not document that they lived where they claimed, even though people provided documentation
06:31 PM roycroft: we still have thousands of people in southern oregon and just outside eugene who are still homeless because fema refused to give them fema trailers to stay in
06:49 PM bjorkintosh: roycroft, of course fema refused to help. they should have had the common sense to be super rich in the first place!
07:23 PM CaptBattery is now known as CaptHindsight
07:50 PM veegee: I've got a great pitch for the dragons den
07:50 PM veegee: Here's the pitch:
07:51 PM veegee: I'm looking for $0 for 100% to install a vent shaft in the den connected to a chlorine gas supply and a pump
07:51 PM veegee: When I flick the switch from the outside, all the exits lock shut and the chamber becomes pretty gas tight
07:52 PM veegee: Then it pumps in chlorine gas and in just a few minutes, the world becomes a better place for everyone
08:00 PM htasta: huh?
08:03 PM veegee: htasta a device that reduces the amount of greed and evil in the world
08:03 PM htasta: oh, ok lol
08:03 PM veegee: Yeah I'll even do the installation for free myself
08:06 PM CaptHindsight: how Canadians solve it https://www.youtube.com/watch?v=pnsroOL-MEk
08:11 PM bjorkintosh: a ... gas chamber, veegee??
08:11 PM veegee: bjorkintosh bingo
08:23 PM bjorkintosh: it's so final though!
08:36 PM veegee: These guys are all just small timers though
08:36 PM veegee: They're not really the ones driving the wealth inequality and general suffering
08:37 PM veegee: They're just the tiny maggots taking advantage of the system
09:03 PM Tom_L: still think my threads look better
09:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/Pressure_test_cap3.jpg
09:05 PM XXCoder: yeah
09:05 PM Tom_L: but i suppose in a pinch you could do that
09:05 PM Tom_L: did he take more than one pass?
09:05 PM Tom_L: generally single point takes multiple passes
09:06 PM XXCoder: bunch of passes yeah
09:06 PM Tom_L: i skipped alot of it
09:07 PM Tom_L: did he do one or multiple?
09:07 PM Tom_L: with a 'tap' like threadmill i think you'd do a single round
09:08 PM Tom_L: but they're limited to one size
09:08 PM XXCoder: basically go in, go nearer center, back out then go out more than before, repeat
09:08 PM XXCoder: few times
09:08 PM _unreal_: so testing out my USB scope cam
09:08 PM XXCoder: its some odd thread size it seems
09:08 PM Tom_L: he didn't use the index on the lathe?
09:09 PM _unreal_: aside from the lense being horribly scratched. once you get past the focus point its great.
09:09 PM Tom_L: odd or not, it's doable
09:09 PM Tom_L: that cup i did was 1.6" iirc
09:09 PM Tom_L: no particular size just random
09:09 PM XXCoder: hmm ok
09:10 PM Tom_L: just gotta calculate the major minor pitch diameters
09:11 PM Tom_L: been having fun with the threadmills lately
09:12 PM roycroft: speaking of tapping, i mostly got my fence fitted and modified, but i was getting tired (i had to go to work at 5am again today for a few hours), and the final step is drilling/tapping for some 4-40 screws
09:13 PM roycroft: so i decided to quit for the day and do that tomorrow, when i'm more easily able to focus
09:13 PM XXCoder: tom nice :) yeah i think threadmills is better, in least for certain diameters
09:13 PM XXCoder: lasts much longer too
09:14 PM * roycroft wants to try threadmills some day
09:16 PM Tom_L: i'd struggle if i didn't have the macro i wrote for them
09:16 PM roycroft: well i don't have a cnc mill at this point, so they're right out for me for now
09:17 PM XXCoder: latest in resin dumbassery https://youtu.be/dUcuLd3ElS4
09:17 PM XXCoder: return to making epoxy screws and drill
09:21 PM roycroft: i just clicked on that
09:21 PM roycroft: i watch for about 4 seconds, and wondered "why?"
09:21 PM roycroft: and closed the window
09:21 PM XXCoder: he does crazy stuff with epoxy heh
09:22 PM XXCoder: im learning a lot of what not to do!
09:22 PM Tom_L: roycroft, glad you did that for me :)
09:23 PM roycroft: i'm sometimes too adventurous for my own good
09:23 PM XXCoder: lol
09:25 PM roycroft: a new round of boeing planes have been grounded
09:26 PM Tom_L: what this time?
09:26 PM roycroft: i guess the faa don't take kindly to airplanes whose engines fall off
09:26 PM roycroft: 777
09:26 PM Tom_L: the one the engine blew up?
09:26 PM XXCoder: yeah? whats happening ahh yea that one
09:26 PM Tom_L: it stayed attached
09:26 PM Tom_L: mostly
09:26 PM XXCoder: they shouldnt have replaced ceo with business one, but keep engineeer
09:26 PM Tom_L: they shouldn't have closed the wichita factory :)
09:27 PM Tom_L: too many fuckups since then
09:27 PM Tom_L: spirit still builds the tubes though
09:27 PM XXCoder: of course results of that epoxy stuff is crap. lol
09:28 PM roycroft: they should not have moved the corporate offices from seattle to chicago
09:28 PM roycroft: that's when it all started
09:29 PM XXCoder: it started with replacing engineer ceo witg business ceo
09:29 PM XXCoder: planes is HARD to do so.
09:29 PM XXCoder: trying to cheapen it is big mistake
09:29 PM roycroft: is that what precipitated the move to chicago?
09:30 PM Tom_L: we've got an excess of engineers here
09:30 PM XXCoder: roy if I recall timeline correctly yeah
09:30 PM Tom_L: alot of em go down to gulfstream etc
09:30 PM roycroft: i'll go along with that then
09:31 PM roycroft: i know it was when they moved to chicago that i saw things going downhill
09:31 PM Tom_L: it ended up good for us though
09:31 PM Tom_L: spirit not only does boeing work but airbus and others now too
09:32 PM roycroft: if the change in ceo is what caused the move then that would be the real beginning
09:32 PM XXCoder: i just have feeling that it means I might not be rehired for bit more
09:32 PM Tom_L: airbus moved a bunch of engineers out to the college campus in a new building
09:32 PM Tom_L: XXCoder, it's still slow here as well
09:32 PM XXCoder: sucks
09:33 PM XXCoder: im thinking about some sorta entry level work at home stuff
09:33 PM Tom_L: my one kid has managed to keep his job but the other one was layed off twice
09:33 PM Tom_L: he's going back for HVAC as a backup
09:33 PM XXCoder: like data entry, because my back isnt recovering and my dizzyness is stubborn
09:37 PM XXCoder: any of you guys know possibly good one?
09:38 PM Tom_L: not off hand
09:38 PM XXCoder: ok
09:39 PM roycroft: funny you should mention that though
09:39 PM roycroft: i'm going to interview on tuesday for a volunteer position at the country fair
09:39 PM XXCoder: nice
09:39 PM roycroft: the position would be membership/elections secretary
09:39 PM roycroft: and it would involve a fair amount of data entry
09:40 PM roycroft: i've been wanting for several years to get a staff position at the fair so i would not have to keep working at a booth
09:40 PM Tom_L: i volunteered part time for the red cross data entry few years back
09:40 PM Tom_L: they always need drivers
09:41 PM XXCoder: roy interesting. may be a way to get experence for that heh
09:41 PM Tom_L: paid positions
09:41 PM roycroft: and this would be the perfect position - it would involve an hour or 2 per week throughout most of the year, 10 hours or so per week for a few weeks before the board election, and zero work during the fair itself
09:41 PM roycroft: so i'd be totally free to enjoy the fair, with no responsibilities
09:41 PM XXCoder: nice
09:41 PM Tom_L: they cancelled our state fair this last year
09:41 PM roycroft: my booth gig is not too bad
09:42 PM roycroft: but i'd rather not have to have to work any shifts during the fair
09:42 PM roycroft: the country fair was cancelled last year, and this year as well
09:42 PM roycroft: they had a virtual fair last year
09:43 PM roycroft: if i'm honest, that's another reason i'm interested in this position
09:43 PM roycroft: i really look forward to the fair every year, and i felt a real loss last year when it was cancelled
09:43 PM roycroft: with this position, i'd be involved with it year-roudn
09:43 PM roycroft: round
09:44 PM * roycroft is thinking about how ugly 6-32 screws would look in his saw fence, because he really hates tapping 4-40 screw holes
09:44 PM Tom_L: you do wood projects for your booth?
09:44 PM roycroft: i do booth construction
09:44 PM roycroft: i don't sell at the booth
09:44 PM roycroft: it's herbal products
09:44 PM Tom_L: ahh
09:45 PM roycroft: the booths are permanent fixtures, but they need to be taken down to a shell every year after fair, and put back together before fair the next year
09:45 PM Tom_L: 4-40 in cast shouldn't be that bad
09:46 PM roycroft: basically, the fair site belongs to nature, and the fair borrows it for a few weeks per year
09:46 PM roycroft: the threaded holes will be in hot rolled steel
09:46 PM XXCoder: literal herbs or herb everyone talks about?
09:46 PM roycroft: although the mill scale is gone
09:46 PM roycroft: body cary products type of stuff
09:46 PM roycroft: and medicinal herbs
09:47 PM roycroft: the oregon country fair is a drug and alcohol free event
09:47 PM roycroft: wink wink nudge nudge say no more
09:47 PM roycroft: the public facing part of it absolutely is drug and alcohol free
09:47 PM XXCoder: interesting
09:48 PM XXCoder: i dont use any thc just cbd myself
09:48 PM roycroft: but behind the booths folks take a more relaxed approach to life
09:48 PM XXCoder: i make my own oil to save a lot
09:48 PM roycroft: i bring 10-15 gallons of homebrew to the fair with me
09:49 PM XXCoder: cool :)
09:49 PM Tom_L: my barber was selling moonshine last year
09:49 PM roycroft: if i give up the booth position i probably won't be able to do that any more
09:49 PM roycroft: i have a great situation right now - i work at one of the oldest booths at the fair, and we have camping right behind the booth
09:49 PM roycroft: so i can set up my tent there, and set up the kegs by my tent
09:50 PM roycroft: but with the staff position i'll be in a really crowed campsite and there will be no room for kegs
09:50 PM roycroft: i'm thinking i might keep my booth gig, sort of
09:50 PM roycroft: i'd get my wristband and parking pass with the staff position
09:50 PM roycroft: so the booth rep would not have to pay for that
09:51 PM roycroft: i'd volunteer to do the booth construction work and pack in and pack out still in exchange for a camping spot behind the booth
09:51 PM roycroft: i have a full size cargo van, and use that to haul everything too and from the fair for the booth
09:52 PM XXCoder: that camp out in middle of wastelands?
09:52 PM XXCoder: burning man something
09:52 PM roycroft: i also live 15 minutes away from the fair site, and the the booth rep lives in vancouver washington - 2 hours away
09:52 PM roycroft: it's 15 minutes west of eugene
09:52 PM XXCoder: ah not that then
09:52 PM roycroft: in veneta oregon
09:52 PM XXCoder: im bit concerned with covid and all
09:53 PM roycroft: that's why the fair is virtual
09:54 PM XXCoder: thats good
09:54 PM roycroft: they're not going to have a live event again until it's safe
09:54 PM XXCoder: maybe I can visit in future whats entry fee
09:54 PM roycroft: i think it's about $25/day
09:55 PM XXCoder: not bad
09:55 PM XXCoder: i wouldnt visit any "back of booth" as I dont drink or want anything else
09:55 PM XXCoder: but might be fn
09:55 PM XXCoder: fun
09:58 PM roycroft: https://www.youtube.com/watch?v=PCEJSEbpC8s
09:58 PM roycroft: conceptually, burning man would be neat to go to
09:58 PM roycroft: i like the idea of it
09:58 PM roycroft: but i've never been
09:58 PM roycroft: i don't like the middle of the desert part of it
09:59 PM XXCoder: heard it sucks now
09:59 PM XXCoder: but then whatever
10:02 PM Rab: I'd never pay to get into a gift economy.
10:09 PM roycroft: what is a "gift economy"?
10:09 PM XXCoder: tou pay for stuff by gifting I guess
10:09 PM XXCoder: like burning man
10:09 PM XXCoder: rab I dont think oregon one is like that
10:10 PM roycroft: oh, the barter stuff
10:10 PM roycroft: ocf is not about that
10:10 PM patb: gotta love wallmart
10:10 PM XXCoder: barter is what it actually is yeah
10:10 PM patb: extention cord 12.98
10:11 PM patb: +1000$ delivery
10:11 PM roycroft: there used to be a barter fair after the fair, but that was for vendors who did not want to haul their unsold goods back home
10:12 PM * roycroft has only been to a wal*mart once, and that was in north dakota, about 25 years ago
10:12 PM Tom_L: you take some of my junk home and i'll take some of yours...
10:12 PM XXCoder: last time i went to walmart was... 8 months ago. they have rice cooker for half price of others
10:12 PM XXCoder: before that it was 6 years? ago
10:12 PM roycroft: i actually wouldn't mind getting a craft booth at the fair
10:13 PM roycroft: but it takes years to get juried in, and then one only gets the right to sell there
10:13 PM roycroft: it usually takes years after that to find a booth to sell at
10:14 PM roycroft: simpsons are doing a west side story thing tonight
10:15 PM roycroft: i should say, they started with a spoof on a west side story song
10:15 PM roycroft: we'll see how the episode goes
10:16 PM Rab: roycroft, XXCoder, I specifically mean Burning Man (and related events) which charge a steep admission but mandate a cashless economy inside.
10:16 PM XXCoder: indeed. oregon one dont look like that like roy said
10:16 PM Rab: I haven't been to OCF so I can't comment, but it seems like a fine event. ;)
10:16 PM roycroft: my sense is that burning man is more a "libertarian" hippie fest
10:17 PM roycroft: ocf is just a bunch of hippies
10:17 PM roycroft: real hippies
10:18 PM Rab: The Rainbow Gathering is an example of a truly free event with a gift economy, but it's not my kinda thing.
10:18 PM roycroft: there's a food booth there - chez ray - that was run by the grateful dead's chef until he passed a couple years ago
10:20 PM roycroft: the vendor booths are about making money, but everything has to be made by the booth rep and crew - no outsourcing at all
10:20 PM roycroft: in fact, the utilikilt guy got kicked out a few years ago because he had started outsourcing zipper installation in some of his kilts
10:20 PM roycroft: he claimed that he did not sell any of those kilts at the fair, but they kicked him out anyway
10:21 PM roycroft: and as i alluded to earlier, to sell crafts there you have to submit samples to a jury who decided if your stuff is worthy or not
10:21 PM roycroft: but besides the craft and food booths, there are about a dozen music/performance stages
10:22 PM roycroft: several educational stages
10:22 PM roycroft: a really nice sauna/shower facility
10:22 PM roycroft: everything a hippie would ever want ;)
10:24 PM roycroft: now they're doing a billie ilish song
10:24 PM roycroft: quite the contrast to west side story
10:38 PM veegee: How do they weld grade 100 chain?
10:38 PM veegee: That is, my chain sling has a welded link connecting the hook to the chain
10:39 PM veegee: If you're manufacturing the entire chain, you can quench and temper it all at once
10:39 PM veegee: But how do you quench and temper the single link after welding it to the hook?
