02:40 AM pingufan: morning
02:45 AM pingufan: what happens when I use a 200W VFD drive with a 250W spindle motor? I do not need 250W at all. But the VFD I found is small enough to fit into my CNC enclosure.
02:45 AM pingufan: If the motor power is then only limited, it is ok.
02:59 AM CaptHindsight: the motor don't know
03:00 AM CaptHindsight: it only go by go muchy much there is power (v x a)
03:02 AM CaptHindsight: if there is only so much P ( v x a) it only have so much applied torque
03:03 AM CaptHindsight: no bad thing (smoke go boom) (make baby, etc)
03:03 AM CaptHindsight: only less https://en.wikipedia.org/wiki/Newton_metre
03:05 AM CaptHindsight: pingufan gone, he no stay for wisdom cnc
03:05 AM CaptHindsight: his cnc boom go
03:06 AM CaptHindsight: make baby, orange pumpkin, etc.
03:11 AM sensille: [x] baby
05:03 AM jthornton: morning
05:10 AM Tom_L: morning
05:12 AM Deejay: hi
05:21 AM jthornton: the builders are almost done with the lean to
05:29 AM XXCoder: damn guy at work had a dumbass day lol
05:29 AM XXCoder: fixture was too tight, so he hammered part in HARD
05:30 AM XXCoder: he really worked part out hard, and destroyed fixture and jammed part of fixture into part
05:30 AM XXCoder: setup was screwy too
05:39 AM jthornton: dang, bad day for him I guess
05:42 AM XXCoder: yeah
05:42 AM XXCoder: not knowing is okay, hes new
05:42 AM XXCoder: but not asking for help?
05:43 AM XXCoder: they have to make new fixture, THEN do setup again
05:43 AM jthornton: yea, if it don't look right ask for help
05:43 AM jthornton: was the part out of spec?
05:43 AM XXCoder: or fixture ois
05:43 AM XXCoder: in either case dont hammer part in, ever
05:44 AM XXCoder: first op was lathe, lathes easily make super duper accurate parts than mills
05:52 AM RyanS: i wonder if that's a similar reason that lathes have less chatter than mills comparing similar size machines. it's a concentric balanced load with more of a shearing cut.
05:53 AM XXCoder: the tech is also 5,000 years old
05:53 AM XXCoder: ;)
05:53 AM XXCoder: though cnc is slightly more recent
05:59 AM RyanS: hmm, a caveman with a pointy tool probably did a kind of milling process
05:59 AM XXCoder: lol maybe
06:00 AM XXCoder: early cnc mill you can really see orgin of drill press
06:00 AM XXCoder: im not sure on exact evolution and invention steps for cnc mill though
06:03 AM RyanS: http://www.oocities.org/unforbidden_geology/ancient_egyptian_copper_coring_drills.html Egyptian drill with abrasive media
06:03 AM RyanS: early water jet
06:03 AM XXCoder: precursor to drill press
06:03 AM XXCoder: one thing they have plenty of is sand
06:04 AM XXCoder: pretty cool
06:05 AM RyanS: it's like trying to sell abrasive media to an Egyptian
06:05 AM XXCoder: still possible, just not sand

08:59 AM perry_j1987: morning all
09:00 AM JT-Shop: morning
09:00 AM perry_j1987: got my coffee
09:01 AM JT-Shop: coffee long gone hours ago...
09:02 AM perry_j1987: just got in my first split thread die
09:03 AM JT-Shop: not familiar with that term
09:03 AM perry_j1987: split die with the setscrew to adjust
09:04 AM perry_j1987: i want to try adjusting some threads to be real tight
09:06 AM JT-Shop: ah ok, been a long time since I've seen one of those
09:08 AM perry_j1987: koolmist sent me a sample of their stuff to mix up
09:08 AM perry_j1987: was going to buy small bottle but everybody only sells gallon size now
09:33 AM JT-Shop: http://gnipsel.com/images/equipment-shed/lean-to-07.jpg
09:39 AM perry_j1987: looks like a nice spot for a bandsaw mill
09:39 AM JT-Shop: that and tractors and backhoe
09:40 AM JT-Shop: neighbor has a bandsaw mill so I just need to buy blades and stack it over here
09:40 AM perry_j1987: ah lucky
09:41 AM perry_j1987: where are you located? does he take requests heh
10:25 AM jym: Moring
10:29 AM skunkworks: moring?
10:31 AM Deejay: boring
10:34 AM skunkworks: pouring...
11:00 AM perry_j1987: wow koolmist sent me 3 bottles heh
11:24 AM pcw_home: Don't drink them all at once...
11:25 AM perry_j1987: heh
11:27 AM Loetmichel: *HRMMMPHH* let me tell you: getting old isnt nice... just went to the optician and ordered new glasses... 500 eur down the drain... varifocal lenses arent cheap :-(
11:34 AM perry_j1987: time to head to neverland
11:44 AM jym: skunkworks: lovely
11:45 AM jym: jthornton, etc all.... This is the wood stove flue pipe exiting the roof, https://i.imgur.com/KfDoQaN.jpg That's sealant (silicone?) that's cracking. Is that excessive heat or just the wrong sealant that was put on???
11:49 AM weenerdog: howdy gents
11:49 AM weenerdog: and gentettes
11:49 AM weenerdog: jt, choo round?
11:54 AM JT-Shop: a little
11:56 AM Tom_L: what's the lean to for?
11:56 AM Tom_L: didn't make the last shed big enough?
11:56 AM jym: Tom_L: is that to me?
11:57 AM JT-Shop: a place to put the tractors and backhoe and lumber that is drying
11:57 AM jym: JT-Shop did oyu see my pic?
11:57 AM Tom_L: no
11:58 AM weenerdog: jt, you know much about atv carbs?
11:59 AM weenerdog: specifically pilot screw adjustment and altitude
11:59 AM Loetmichel: weenerdog: you need mustie1 for that ;)
11:59 AM weenerdog: cool thx
12:00 PM weenerdog: the honda service manual is vague. they sell a high altitude jet, but they have instructions for "over 3000 feet" and "under 5000 feet"... i'm at 4100 :)
12:00 PM JT-Shop: weenerdog: never worked on an atv... lots of motorcycles and other equipment up to 18,900 cubic inch 20 cylinder diesel engines...
12:07 PM JT-Shop: that would be over 3000 feet...
12:13 PM JT-Shop: not yet jym
12:28 PM JT-Shop: jym: you have to use OSI Quad...
12:34 PM jym: JT-Shop That was there before we even bought the place.
12:35 PM jym: JT-Shop My biggest concern is if that's just mild residual heat AND the wrong sealant, OR a potential fire hazard because someone did a poor install
12:49 PM perry_j1987: just checked thingiverse for some sort of oil can to print for my mini lathe
12:49 PM perry_j1987: nothing popped out at me
12:49 PM MarcelineVQ: jym: all silicone (that I've seen) cracks eventually, even just from the consistent expansion/constraction of sunlight hitting it, but if you're worried then now's a good time to pull that flue cap off and inspect then install since you need to reseal anyway
12:50 PM jym: MarcelineVQ: I do get that it breaks down, but those heat burn marks????
12:51 PM MarcelineVQ: oh are those burn marks or is that older sealant? I thought it was just roofing tar
12:51 PM MarcelineVQ: Was there more than one pic?
12:51 PM jym: That's clear sealant (or was)
12:52 PM jym: https://i.imgur.com/KfDoQaN.jpg
12:54 PM MarcelineVQ: Oh okay you're worried that the silicon that has turned yellow-brown is burnt? I wasn't sure if you meant the black stuff at first. It'd definitely hard to tell from the picture whether that's just weathering or not. Do you have a thermometer you can leave on there as the stove runs?
12:56 PM MarcelineVQ: The fact that the roofing itself isn't having paint issues is a good sign at least
12:57 PM MarcelineVQ: Since heat would accelerate oxidization in the area over time
12:58 PM jthornton: could be bird shit too, if it's a triple wall it ain't burnt
12:59 PM MarcelineVQ: That'd be some carefully placed bird shit haha
01:00 PM jthornton: that rules out my birds they shit everywhere!
01:00 PM jym: It's NOT bird shit. IT's a double wall flue pipe
01:01 PM jthornton: double wall can get a bit warm if a flue fire has been going in there
01:02 PM MarcelineVQ: silicone turning yellow and cracking isn't rare, algae collecting dust can stain it and it cracks eventually anyway, but it's good to double-check things, I'd run the stove hot and stick a thermometer on the roofing next to the silicone
01:02 PM jthornton: if your concerned about the flue then call an expert
01:02 PM jym: But the roof cap extends out further than the 6"ID /10" ? OD
01:02 PM jym: sorry hard to explain
01:03 PM Tom_L: if you're worried about it, go to o'rileys and get some high temp silicone
01:06 PM jym: Tom_L: I can do that, and plan on it if it's just the wrong sealant on there. But that's BURNT sealan that's cracked, I don't know if that's excessive heat or just bad sealant,
01:10 PM MarcelineVQ: jym: have you run that stove yourself before?
01:12 PM jym: MarcelineVQ: Yes, but not on a regular basis. The sealant was semi-cracked about 3 years ago, but not charred as it is now.
01:13 PM MarcelineVQ: do you know if the pipe is double-walled the whole way up?
01:13 PM jym: imgur is being a PITA today, I'm trying to upload better pics
01:14 PM jym: MarcelineVQ: It SHOULD be, I don't know if it is at the stove, but I have no reason to think that it wouldn't be.
01:15 PM MarcelineVQ: alright then really just suggest to put an accurate thermometer right next to that silicone and run the stove hot for a day, you can determine at that time whether there's a general heat concern
01:15 PM jym: MarcelineVQ: I took off the spark arrestor and looked down, I didn't see eveidence of double to single wall
01:16 PM MarcelineVQ: you'll want to shade the thermometer somewhat if possible, sun can really throw those things off in my experience
01:16 PM jym: MarcelineVQ: I have an IR gun
01:17 PM MarcelineVQ: fancy
01:19 PM MarcelineVQ: I've got to do similar myself come to think of it, we're in a new place and the last guy that was in here did some installs and he's not known for looking up how to do things before doing them. Wouldn't be too surprising if my covers looks exactly the same as yours
01:22 PM jym: MarcelineVQ: I've just never seen silicone do that before personally, so it's that "unknown" factor.
01:22 PM MarcelineVQ: It's probably bathroom caulk <_<
01:22 PM jym: But I've never seen silicone "crack" before either.
01:22 PM MarcelineVQ: so residual acetone could brown like that
01:23 PM MarcelineVQ: oh? man that shit cracks all the time around here, even the rv stuff
01:23 PM jym: I dont know what oyu call that cone thing
01:24 PM jym: MarcelineVQ: REally? 100% PURE silicone cracks???
01:25 PM MarcelineVQ: I doubt it's 100% pure silicone, it'll have something in it depending on its purpose and a solvent (carrier really) that evaporates so that it's easier to apply. but yes even pure silicone can crack pretty easily because it accrues microtears that expand over time, and you get a lot of expansion and contraction oudoors from temperature
01:25 PM Tom_L: vent pipe flashing
01:26 PM jym: MarcelineVQ: Yeah, I've seen the newwwer bathroom caulk that LOOKS like 100% silicone, but it's laytex
01:26 PM jym: Tom_L: ty
01:26 PM Tom_L: or flue flashing
01:26 PM MarcelineVQ: Tom_L: ah thanks, I couldn't remember either
01:27 PM Tom_L: typically vent pipe flashing will have a rubber seal and flue flashing won't
01:29 PM MarcelineVQ: looks like boot is another term for it, though that's a new one to me
01:29 PM Tom_L: probably a locale thing
01:30 PM Tom_L: boot is a trunk here
01:30 PM Tom_L: bonnet, hood
01:30 PM Tom_L: boot is also something you put on your foot to kick ass
01:51 PM jym: There's rubber boot for water sealing too
02:04 PM * weenerdog scrolls up. certified woodstoveologist here. let me read
02:08 PM weenerdog: if it draws well i wouldn't sweat it. maybe automotive form-a-gasket stuff would do it?
02:09 PM weenerdog: something hitemp (see? i'm great at stating the obvious) :)
02:09 PM weenerdog: it looks fine tho
02:10 PM jym: weenerdog: So that blacked sealant that was originally clear, "looks fine" ???
02:11 PM weenerdog: i dunno. i'm a farmer, not a chemist.
02:13 PM weenerdog: it isn't gonna set anything on fire running into steel like that.
02:13 PM weenerdog: does it draw?
02:14 PM weenerdog: like... hold a bic lighter up to the draft. if its drawing well, as you get close, it should actually suck the bic so hard it goes out
02:14 PM Connor: CaptHindsight: What about this for paint? https://leblondusa.com/tips-for-repainting-a-lathe/
02:15 PM weenerdog: from that article, Connor - RUST? TRY OSPHO.
02:15 PM weenerdog: ospho is the trick for rusty stuff.
02:15 PM weenerdog: muy bueno
02:15 PM jym: weenerdog: it draws fine, My concern is the heat at the ceiling/roof adn if it's excesive
02:16 PM weenerdog: what does your thermometer gun say?
02:16 PM Connor: No rust really.. some slight brown/dark patina.
02:17 PM jym: weenerdog: I havne't been on the roof when the wood stove if going. it's slippery than hell
02:17 PM Connor: We're using evaporust on everything.. sonic cleaner on the smaller parts too.
02:17 PM weenerdog: thats called 'character' :)
02:18 PM weenerdog: jym, my redneck expert gut feeling analysis is its not a problem.
02:19 PM * jthornton goes outside to replace some hydraulic hoses...
02:19 PM weenerdog: if it stays sealed, in the immortal words of Dale Earnhardt (Sr.), drive it like you stole it :)
02:19 PM jym: jthornton: good luck with that
02:20 PM CaptHindsight: Connor: it's a water based acrylic https://www.paintdocs.com/docs/webPDF.jsp?SITEID=SWPROTECT&doctype=PDS&lang=E&prodno=B66W111
02:20 PM weenerdog: Connor, powder coating?
02:20 PM weenerdog: would that be feasible?
02:21 PM Connor: We do have a powder coat gun.. but nothing large enough to bake it in for the bed of the lathe.. smaller parts yes.
02:21 PM CaptHindsight: water based acrylics are low toxicity
02:22 PM Connor: CaptHindsight: What's the issue with water based acrylic?
02:22 PM Connor: Is that not good for this application?
02:22 PM Connor: I know nothing about paints..
02:22 PM weenerdog: toxicity shmoxicity, capt. if he was carful, we'd be having this conversation in #sewingmachins :)
02:22 PM weenerdog: i do not know much about paints
02:23 PM CaptHindsight: not as tough as epoxides or urethanes
02:23 PM CaptHindsight: how tough is up to you
02:23 PM CaptHindsight: sample and test
02:23 PM weenerdog: my personal aesthetic would cause me to clean it up, but screw painting it.
02:24 PM weenerdog: i like patina and surface rust rubbed smooth with use.
02:26 PM Connor: We have a Sherwin-Williams local..
02:26 PM Connor: I don't want to deal with HD or Lowes
02:26 PM Connor: Just trying to find a place that I could pick it up locally.
02:27 PM CaptHindsight: they don't stock industrial anyway
02:27 PM CaptHindsight: go to SW and get a 1-pint sample
02:28 PM Connor: Oh. Damn
02:28 PM Connor: Gloss, Semi-Gloss, Matt?
02:29 PM Connor: I was thinking Semi-Gloss, but Gloss might be easier to clean?
02:29 PM CaptHindsight: oils will wipe off gloss easier than from matt
02:31 PM Connor: That Rust-Oleum.. What was it?
02:33 PM CaptHindsight: Farm Implement
02:34 PM CaptHindsight: https://www.rustoleum.com/product-catalog/consumer-brands/specialty/farm-and-implement
02:34 PM Connor: Yea.. But, base.. Epoxy urethane acrylic?
02:36 PM CaptHindsight: it is an alkyd enamel, oil based
02:37 PM Connor: You think flood coolant would eat it up?
02:38 PM CaptHindsight: the most important thing is prep
02:39 PM CaptHindsight: for price, durability and safety I'd go epoxy primmer and then rustoleum top coat within 1 day of priming
02:40 PM CaptHindsight: lower price will be a DTM (direct to metal) water or oil based
02:40 PM Connor: So, we do need a primer on top of that farm and implement..
02:40 PM CaptHindsight: but likely will not hold up as long as epoxy primer and top coat
02:41 PM CaptHindsight: you can DTM the Rustoleum farm and Implement but the epoxy primer just bonds so well the metal and it's cheap and easy
02:42 PM CaptHindsight: I shot a forklift with it recently
02:43 PM CaptHindsight: had to use a chisel to get the cured paint off
02:43 PM CaptHindsight: epoxy dry time is like 1 hour
02:43 PM CaptHindsight: Rustoleum is dry to touch in a couple hours but a few days for full dry
02:45 PM Connor: CaptHindsight: I just sent you a DM.
02:49 PM jym: Kinda cool... Making Benchtop Metal Cutting Shears https://www.youtube.com/watch?v=LzpV6T9Yltc
02:57 PM Rab: Connor, I used the regular gloss Rustoleum from HD here, applied with an airless paint sprayer: http://reboots.g-cipher.net/container/shelving.jpg
02:57 PM Rab: It dried to the touch after a few hours, but kept outgassing for a long time...it was pretty stinky for several months. Now it's rock hard.
02:57 PM Rab: I'm sure the Farm & Implement type is even better.
03:02 PM CaptHindsight: yes, takes a few days for the solvents to evaporate
03:06 PM CaptHindsight: I used some isocyante urethanes for clear topcoats that cured incredibly hard ~$500/gal
03:06 PM CaptHindsight: we even had trouble sanding them
03:22 PM weenerdog: I dunno what they coat commercial grade pergo flooring with, but when I sawed it on my chop saw, it threw sparks when the blade kissed it
03:26 PM CaptHindsight: HDF core can contain fillers that are mineral/stones
03:26 PM CaptHindsight: sand size particles
03:32 PM weenerdog: high density fuckawhat?
03:32 PM weenerdog: fiber?
03:32 PM weenerdog: i know its tuff stuff
03:33 PM weenerdog: i dropped my makita chopsaw on it with a corner of the base hitting first and it didn't scratch or dent the stuff
03:33 PM CaptHindsight: fiberglass pultrusions are similar
03:33 PM weenerdog: whut is a 'pultrusion'?
03:34 PM weenerdog: new word
03:34 PM CaptHindsight: https://en.wikipedia.org/wiki/Pultrusion
03:34 PM weenerdog: gracias. reading.
03:34 PM weenerdog: well
03:34 PM CaptHindsight: https://www.youtube.com/watch?v=4MoHNZB5b_Y
03:34 PM weenerdog: thank you for edifying me :)
03:36 PM weenerdog: ingenious
03:36 PM CaptHindsight: https://www.strongwell.com/products/structural-shapes-and-plate/
03:36 PM weenerdog: thank you capt
03:37 PM CaptHindsight: https://www.strongwell.com/products/ballistic-and-storm-panels/
03:37 PM weenerdog: i bet it makes stout stuff
03:38 PM gloops: start windows 'normally' ???
03:38 PM weenerdog: lol
03:41 PM * weenerdog go to dinner party at friends' house :)
03:42 PM weenerdog: you guys have a good one. thanks for the knowledge!
03:43 PM JT-Shop: jym: thanks but luck never plays a part on changing hydraulic hoses, usually wrenches, rags, cussing, and a tube of Rectorseal will get the job done
03:51 PM _unreal_: just finished milling my upper section to the dust shoe
03:51 PM _unreal_: and got the magnets bedded in
03:51 PM _unreal_: everything is matched up nice
03:52 PM _unreal_: now I just need to design and mill out the lower part. but I'm going to wait on that till my supply of brush material shows up
03:52 PM _unreal_: speaking of I should check
03:59 PM roycroft: if the shoe fits, suck it
04:02 PM _unreal_: and my material is here. now I'm wishing I had looked for even shorter stock.... oh well 70mm will work
04:02 PM _unreal_: hair long but I can work around it
04:03 PM _unreal_: not sure if I have any more usable material :/
04:03 PM _unreal_: I think I'm going to use PVC board
04:03 PM _unreal_: easyer to mill and lighter then the poly board I just sued for the upper section
04:03 PM _unreal_: !! oooh its 5oclock somewhere :)
04:14 PM Deejay: gn8
04:14 PM JT-Shop: it's 5 o'clock at my sisters house
04:15 PM JT-Shop: s
04:15 PM _unreal_: 5:10 and drinking tequila
04:15 PM _unreal_: wooo haaa
04:17 PM _unreal_: I live very close to my father so he was just showing me the cutting board he finished bilding for his girl friend. and told me he had some left over wood. I told him COOL
04:17 PM _unreal_: let me see them and I'll make a cheese cutting board with a nice logo on it.
04:55 PM * roycroft is on vacation in 10 minutes
04:56 PM roycroft: just over 9 minutes :)
04:56 PM roycroft: less than 9 minutes now
04:57 PM CaptHindsight: how much stretch in a 3/8" wide MXL belt (9.5mm) with a distance of ~3" (75mm) between centers?
04:58 PM CaptHindsight: kevlar version
05:00 PM CaptHindsight: https://www.sdp-si.com/D265/HTML/D265T058.html
05:19 PM andypugh: CaptHindsight: Zero, at zero load. More with more load.
05:19 PM CaptHindsight: heh
05:20 PM CaptHindsight: greatest load is when switching directions
05:21 PM andypugh: Unless you know the load, it’s hard to quantify. For a finishing pass, you can probably ignore it.
05:22 PM CaptHindsight: ~50Ncm
05:22 PM CaptHindsight: .5Nm
05:23 PM andypugh: Wild guess… 0.05mm
05:24 PM andypugh: Maybe less. It’s in to the “I don’t care for what I make”
05:24 PM CaptHindsight: https://imgur.com/QoVC0eR
05:25 PM CaptHindsight: no difference measured with direct drive or with 2:1 pulleys and belt
05:25 PM CaptHindsight: 2.54mm pitch screw
05:27 PM CaptHindsight: I usually use belts with pulleys systems with much higher ratios
05:27 PM CaptHindsight: i just wanted to double the motor torque
05:27 PM CaptHindsight: 0.9 deg/step motor
05:40 PM CaptHindsight: looks like it ends up around 0.007%/N
05:46 PM CaptHindsight: in my case ~5um
06:12 PM jthornton: geez a guy placed an order just as I was switching from one hosting site to the new one and I don't have any contact info except his email and he doesn't seem to be responding...
06:13 PM jthornton: hmm he is a member of the forum...
06:14 PM andypugh: Who?
06:14 PM _unreal_: huh?
06:14 PM jthornton: jackh
06:14 PM jthornton: last on the forum 16 apr 2019
06:15 PM jthornton: so not been there in a while
06:23 PM jthornton: it's been quite fun setting up the new store, but I missed a few things...
06:25 PM _unreal_: store
06:25 PM _unreal_: ?
06:26 PM roycroft: so do you like woocommerce?
06:27 PM jthornton: mesaus.com
06:28 PM jthornton: so far it's better than opencart for sure, the functions.php is great being able to make it do what you want and not what some developer wants
06:28 PM jthornton: there's a couple of things yet to figure out like the footer but I'm getting there and the new store is live now
06:29 PM jthornton: hmm roycroft is in stealth mode lol
06:30 PM jthornton: the only thing I dislike is many basic functions are pay plugins
06:31 PM jym: Nice job restoring a 3ph grinder... https://youtu.be/yWMMuFsDIFs?t=1788
06:32 PM * jthornton checks his usage...
06:33 PM jym: That's the last 30 seconds if it matters
06:33 PM * jthornton wonders wtf is using bandwidth...
06:33 PM jthornton: I'm behind the 8 ball now lol
06:34 PM jym: It's only the first 1/3rd of the mont too
06:34 PM jym: month
06:35 PM jthornton: no shit, I should have a spare GB but I don't
06:35 PM jthornton: spending too much time working on the store during metered hours I guess
06:35 PM andypugh: jym: It’s not that nice, compared to https://www.ebay.co.uk/itm/283555813135
06:37 PM andypugh: Or https://www.ebay.co.uk/itm/223508819252
06:38 PM jym: andypugh: I have something for you... https://i.imgur.com/NgZJDeU.jpg
06:39 PM andypugh: And you can buy serious grinders, but they are expensive:

06:39 PM jthornton: wow
06:40 PM jym: andypugh: I don't need a $4000 grinder... EVER, but ty =)
06:41 PM CaptHindsight: jym: http://www.tkx.co.jp/images/grind/tkx_grind_2.jpg
06:42 PM jym: CaptHindsight: lmao
06:57 PM roycroft: no wonder zoro are so expensive - those long long urls they use must involve a lot of overhead
06:59 PM CaptHindsight: I only used the first half of it and the link still worked
06:59 PM roycroft: everything after the ? is just for tracking you, i'm sure
06:59 PM CaptHindsight: it's the built in redundancy redundancy
07:00 PM roycroft: everything before the ? is used to sell their product to you
07:00 PM CaptHindsight: didn't see the ? until now
07:00 PM roycroft: everything after the ? is used to sell you to other vendors by zoro
07:00 PM CaptHindsight: thought it was one without the ?
07:01 PM roycroft: i just pasted up to the ? and it worked fine
07:01 PM roycroft: https://www.zoro.co.uk/shop/power-tools/bench-grinders/ep312-h%2Fduty-double-ended-grinder-400v-3ph/ps/ZT1028508X
07:01 PM roycroft: that works
07:01 PM CaptHindsight: it's OK, my profile includes tampons, diamond dressing wheels, baby formula and automation equipment
07:02 PM roycroft: i just bought some gilsonite (asphaltum) from a fireworks supplier
07:02 PM roycroft: i wonder if that's going to get me on some fbi list
07:02 PM CaptHindsight: I'm a 32 yo woman from Bostwana that votes republican and frequents online bowling suppliers
07:02 PM roycroft: i got it to do some japanning
07:03 PM roycroft: which is not early as exciting a use as some might imagine
07:04 PM CaptHindsight: is it ok to give Best buy thw phone number for the white hosue when they ask for your number?
07:04 PM roycroft: anyway, here's a serious grinder for not nearly so much money:
07:04 PM roycroft: https://eugene.craigslist.org/tls/d/harrisburg-12-double-end-pedestal/6931137751.html
07:04 PM roycroft: if i had room for that i'd get it
07:07 PM CaptHindsight: those grinders spin the wheels in opposite directions
07:08 PM roycroft: then you can alternate wheels to help keep from getting dizzy while you're grinding
07:11 PM jym: CaptHindsight: NSA, not WH
07:19 PM roycroft: give them the number of trump's crapper tweeter phone
07:19 PM CaptHindsight: in always say "7" and that it['s a really old phone
07:20 PM CaptHindsight: going out to buy new fingers, my current ones can't type well
07:31 PM _unreal_: milling the bottom half
07:32 PM _unreal_: and OMG 2hrs to milling this stupid thing
07:33 PM _unreal_: you know its kind of funny. I've decided I dont want to deal with holding the vacuum
07:33 PM _unreal_: for the thing that will hold the vacuum for me
07:33 PM _unreal_: LOL
07:35 PM _unreal_: sigh.. I really want to add gearing to this cnc machine. so I can run the motors faster with power
07:39 PM _unreal_: ?
07:39 PM _unreal_: sigh
07:48 PM Rab: _unreal_, gearing will add backlash.
07:51 PM _unreal_: Rab, I'm refering to belt drive
07:53 PM Rab: That'd be pulleying
07:55 PM Rab: Or belting. I have 2.5:1 on my X/Y: http://reboots.g-cipher.net/rabbot/image/parts07.jpg
07:55 PM _unreal_: big difference?
07:57 PM Tom_L: Rab, what series belt is that?
08:00 PM andypugh: I like the T5 and T2.5 belts
08:01 PM andypugh: Though they might be too metric for many of you.
08:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Motormount1.jpg
08:01 PM Tom_L: i don't remember what those were
08:01 PM Tom_L: but they look similar to his only not as wide
08:05 PM andypugh: https://photos.app.goo.gl/g5nbXqc9MD63q7RF8
08:05 PM andypugh: Is the unconventional setup on my mill X
08:05 PM Tom_L: idler pulley?
08:06 PM andypugh: Multiply concentric rotating nut
08:06 PM andypugh: Yes, there is an idler/tensioner roller
08:07 PM Tom_L: the screw is stationary?
08:07 PM andypugh: Yes
08:07 PM Tom_L: that might work good on long beds too over belt systems
08:08 PM Tom_L: ie plasma or large router tables etc
08:08 PM Tom_L: where you would normally get alot of whip if the screw turned
08:09 PM andypugh: Looking at it, that’s not the final design, as I can’t see the preload collar or the inner bearing retainer.
08:10 PM Tom_L: which part is the bearing?
08:11 PM andypugh: This is the real thing, with vernier preload adjuster
08:11 PM andypugh: https://photos.app.goo.gl/3qsYLEW3CmjArPgG7
08:11 PM andypugh: Darker brown is the bearing.
08:11 PM Tom_L: that's what i was thinking
08:12 PM Tom_L: roller?
08:12 PM andypugh: Double angular contact
08:12 PM gregcnc: They look very narrow in the model, what size are those?
08:14 PM andypugh: I can’t remember. In the end I do recall I used a pair of double ones, as the singles were not available with thin enough section.
08:15 PM jym: andypugh: Did you see the pic from earlier?
08:16 PM andypugh: Same thing here: https://photos.app.goo.gl/8dMc9J4ssaCKwXzx9 Two double-row AC bearings preloaded as if they were single-row, purely for the overall envelope size.
08:16 PM Rab: Tom_L, HTD. Pretty stone age, others like GT3 have a better profile and less backlash.
08:16 PM Tom_L: i couldn't get GT3 in the sizes i needed
08:17 PM Rab: Having said that, it seems to perform OK in my simple application.
08:17 PM andypugh: Sleep time.
08:17 PM Tom_L: bye
08:35 PM roycroft: i just made a sample drawer pull with the template and jig that i have been working on
08:35 PM roycroft: it's a bit rough looking, because i made it out of pine with not the sharpest tooling
08:36 PM roycroft: when i make the batch will have new router bits and will be made of birch
08:36 PM roycroft: but the size is good, it's comfortable, and it looks good
08:37 PM MarcelineVQ: nice
08:37 PM MarcelineVQ: gonna sell drawers?
08:37 PM roycroft: when i make some real ones i'll take pictures
08:38 PM roycroft: no, i just made a bunch of drawers for my lathe stand and belt grinder stand
08:38 PM roycroft: and i have no way to open them easily at the moment
08:38 PM roycroft: but i tell you what
08:38 PM MarcelineVQ: oh I misread you said drawer pull
08:38 PM roycroft: i spent a bunch of time trying to find some drawer pulls ready-made
08:38 PM roycroft: and good quality, attractive wooden ones are all but impossible to find
08:39 PM MarcelineVQ: for a sane price at least
08:39 PM roycroft: i'm having the thought that i may be able to make money doing small batches of them
08:39 PM roycroft: well, the ones that i've found are in the $12-$25 dollar range (each)
08:39 PM roycroft: and while that might be pricey for shop fixtures, for high end furniture it's not bad at all
08:40 PM MarcelineVQ: no it's not bad at all
08:40 PM MarcelineVQ: *that's
08:40 PM roycroft: with my current shop setup i could probably make 10/hour
08:41 PM roycroft: so kind of hard to make good money that way
08:41 PM roycroft: but if i got a proper shaper, instead of using my router table, i could probably double that output easily
08:42 PM roycroft: and then there is profit to be had
08:42 PM roycroft: of course, i have the perpetual problem of having no more room for stationary machines
08:42 PM roycroft: and hardly any room for portable machines
08:42 PM * roycroft needs an extension or a whole new shop
08:43 PM MarcelineVQ: what's the setup that a shaper would addist with, you cut them all out in long passes then bandsaw them to size?
08:43 PM MarcelineVQ: *assist with
08:43 PM roycroft: i could use more robust cutters
08:43 PM roycroft: right now what i have to do is trace the outline of the drawer pull on the wood
08:43 PM roycroft: bandsaw the outer perimeter close to the line
08:43 PM roycroft: mount a template on it
08:43 PM roycroft: route the outside profile
08:44 PM roycroft: bandsaw the inside perimeter close to the line
08:44 PM roycroft: mount it in the jig
08:44 PM roycroft: route the inside profile
08:44 PM roycroft: if i had a shaper with a big cutter i could just rough cut the blanks, and not bother with the bandsawing bit
08:44 PM roycroft: it takes longer to bandsaw close to the line than to route the profile
08:45 PM roycroft: i have a 3hp spindle on the router table
08:45 PM roycroft: it's one of those 80mm water-cooled ones that folks use for cnc applications
08:45 PM roycroft: and that is fine, but my router bits are only 1/2" shank
08:46 PM roycroft: if i try to hog off too much material there would be too much vibration and it would be unsafe
08:46 PM roycroft: but if i had a shaper with a 1" spindle it would be fine
08:47 PM roycroft: although the inner profile has two curves with a 1/4" radious, so that would still be a problem
08:47 PM MarcelineVQ: hmm too bad you don't have 5th axis, you could make them all at once in one setup by using a form tool to shape the underside. like, have the pulls being cut as though they've been attached to the router bed like a drawer
08:47 PM roycroft: i had thought about something like that
08:47 PM MarcelineVQ: you can get pretty close with just 3 axis but it'd be blocky
08:47 PM roycroft: but if i were to do this to make money, i'd go after the high-end furniture market
08:48 PM roycroft: because i would want to make some really nice drawer/cabinet pulls
08:48 PM roycroft: not mass-market crap
08:48 PM roycroft: and folks in that market are generally tolerant of using power tools to make things
08:48 PM roycroft: but they draw the line at cnc
08:48 PM roycroft: they prefer craftsmen who operate machines/tools manually
08:48 PM MarcelineVQ: Hey now you can do nice and efficient at the same time, it's not like it's massss production :>
08:49 PM MarcelineVQ: Besides there's plenty of hand finished to do to cnc parts
08:49 PM roycroft: so if i got a cnc machine to make them i would lose part of my target demographic
08:49 PM MarcelineVQ: finishing
08:49 PM roycroft: yes, of course
08:49 PM roycroft: i'm not saying those folks are right in their thinking
08:49 PM roycroft: but they're the ones with the money that i want
08:49 PM MarcelineVQ: fair enough haha
08:49 PM roycroft: so i have to respect their thinking even if i don't agree with it
08:50 PM roycroft: and i have this ethical problem
08:50 PM roycroft: i would not be able to sleep well if i lied to my customers about using cnc machines
08:50 PM Tom_L: got an example of what you're making/
08:50 PM MarcelineVQ: I've got a particular liking for checkerboard type wood, you know the kind where you have 2 colors of cut ends and you glue them and plane them so that you have a 3d checkerboard log? that'd make really interesting furniture
08:50 PM Tom_L: ?
08:50 PM roycroft: the only way i know of to solve that problem is to not lie to them :)
08:51 PM roycroft: the sample i made is pretty crappy, tom_l
08:51 PM MarcelineVQ: it's important to not lie to your customers until you have time to employ a lobbyist or two
08:51 PM MarcelineVQ: That's when you've made it and can start being a complete fucker
08:51 PM roycroft: i'd rather wait until i get my new tooling and make one out of the proper material
08:51 PM roycroft: which will be in a week, since i'm going to the beach on monday for a few days
08:51 PM roycroft: and the tooling will arrive while i'm gone
08:52 PM roycroft: marcelinevq: that is the person i never want to be
08:52 PM roycroft: and i'm old enough now, having never been that person, that i think i probably never shall be that person
08:52 PM MarcelineVQ: I wouldn't sweat it, it's pretty unlikely for most people even if they wanted that
08:53 PM roycroft: i'd rather have trouble paying my bills than to be deceitful
08:53 PM roycroft: that's probably why i'm not a millionaire
08:54 PM roycroft: my goals in life are to treat people kindly and fairly, and to always be doing someting interesting
08:54 PM roycroft: accumulating a lot of money has never been a goal
08:54 PM MarcelineVQ: Sounds like good goals to me
08:54 PM roycroft: getting enough to do the interesting things, of course, has
08:55 PM roycroft: it's really why i would never get back in the building trades
08:55 PM XXCoder: not sure whgat person you guys is talking about, joining klate late
08:55 PM XXCoder: *lol
08:56 PM MarcelineVQ: XXCoder: you
08:56 PM roycroft: the generic person who takes advantage of others and lies and cheats
08:56 PM roycroft: nobody in particular
08:56 PM MarcelineVQ: oh well now that sounds mean
08:56 PM XXCoder: so, in other words, me like marc says? ;)
08:56 PM MarcelineVQ: hehe
08:56 PM roycroft: i used to do framing, finish carpentry, had a little custom cabinet shop for a few years, and home remodeling/repair
08:57 PM roycroft: it always bothered me that customers just assumed i was goign to try to rip them off
08:57 PM roycroft: because that's the reputation of the trades
08:57 PM XXCoder: theres also feedback loop
08:57 PM XXCoder: people in trade assume others cheat lie etc
08:57 PM roycroft: yeah
08:57 PM XXCoder: then do it, and others assume because of that...
08:57 PM MarcelineVQ: Well, when it comes to trades-work even when people aren't getting ripped off they'll feel like it just because materials and labor adds up fast for anything
08:57 PM roycroft: yes, that's another problem
08:58 PM roycroft: unrealistic expectations on the part of the customer
08:58 PM Tom_L: better materials cost more too
08:58 PM roycroft: but i put much of that problem on the builder/contractor
08:58 PM roycroft: customers need to be trained
08:59 PM MarcelineVQ: but I want it now roycroft and I want it cheap and I want it with a little extra because I'm being so nice and smiling a lot
08:59 PM roycroft: the problem is, of course, that if you're the honest one and put everything on the table up front and try to explain things to the customer, you don't get the job
08:59 PM roycroft: because the scheister next door promises 2x as much for 1/2 the price
08:59 PM roycroft: and then starts jerking the customer around after getting the contract
08:59 PM roycroft: thus reinforcing the notion that contractors are crooks
09:00 PM roycroft: clients are not always angels though
09:00 PM roycroft: i remember one job where we built a second story deck and stairs going up to it
09:01 PM roycroft: i had a sense that the customer was going to be a jerk
09:01 PM roycroft: and, indeed, the customer was constantly trying to find faults that did not exist, asking for a price adjustment
09:02 PM roycroft: on the last day of the job, i told my helper to screw the handrails on the stairs instead of shooting them on with a nail gun
09:02 PM roycroft: and he looked at me really funny, because we normally nailed those things on
09:02 PM roycroft: keep in mind this was the early '80s, where builders did not use screws as much as they do now
09:02 PM roycroft: we finished up
09:02 PM roycroft: client comes out
09:02 PM roycroft: tried to find faults
09:03 PM roycroft: could not
09:03 PM MarcelineVQ: I can think of a good reason to nail handrails though :>
09:03 PM roycroft: then finally said "well i'm just not going to pay you - you can't really do anything about it now that it's done"
09:03 PM roycroft: so i turned to my helper and told him to start taking it down
09:04 PM roycroft: he got one of the handrails unscrewed by the time the check was in my hand
09:04 PM MarcelineVQ: geeze, that's a ballsy move on the client's part, just straight up no pay
09:04 PM roycroft: yes, but that happens sometimes
09:04 PM MarcelineVQ: Well it's like, you really think the guy that made this can't unmake it?
09:05 PM roycroft: fortunately i have a pretty good read on people
09:05 PM roycroft: we could not have salvaged much of it
09:05 PM roycroft: because most of it was glued and nailed
09:05 PM roycroft: and that's what the client was betting on
09:05 PM roycroft: if i tore it all down, i'd be out the cost of materials and my time
09:06 PM MarcelineVQ: and he'd be out a deck and havea cleanup jop, so quite a gamble on his part. wonder if that's worked for him before, probably
09:06 PM roycroft: if i left it in place i could try to negotiate a partial payment or something
09:06 PM roycroft: i'm sure he was betting on my knocking the price way down just to get something
09:07 PM roycroft: i really don't like having to do stuff like that
09:07 PM roycroft: that's a huge reason i got out of the building trades
09:08 PM roycroft: anyway, time to make dinner
09:09 PM roycroft: i'll take some pics when i make my next sample handle, probably next weekend, assuming the tooling arrives when it's due
09:10 PM _unreal_: LI love it when the last pass is a 1/32 on a huge pocket job
09:10 PM MarcelineVQ: cool I'd like to see that
09:11 PM _unreal_: wish granted https://drive.google.com/open?id=1E-aK0gCYo2QxWQyOJo9Ev71vkCAknmJl
09:12 PM MarcelineVQ: well I meant roycroft but sure I'll look at that
09:12 PM MarcelineVQ: what's that there, abs?
09:13 PM _unreal_: starboard
09:13 PM _unreal_: mills like a dream
09:14 PM MarcelineVQ: oh neat material, hdpe with sun protection
09:15 PM _unreal_: yep
09:15 PM _unreal_: any color as well
09:15 PM _unreal_: I'm drowning in it because I work on yachts
09:15 PM _unreal_: here is the 1/32 pass https://drive.google.com/open?id=1E14toi38e6gsqM5C2TwmkVK4_5m0eSfn
09:15 PM _unreal_: I just cleaned it up and took a photo
09:16 PM _unreal_: I'm milling the bottom half to a dust shoe that will stick on with magnets
09:17 PM _unreal_: ?
09:18 PM Tom_L: what software did you end up using to program it?
09:18 PM _unreal_: ?
09:18 PM _unreal_: to design it?
09:18 PM _unreal_: or control
09:19 PM Tom_L: design
09:19 PM _unreal_: I made it in fusion360. but gave up trying to setup the CAM
09:19 PM Tom_L: you're not running linuxcnc on that
09:19 PM _unreal_: then exported it and imported into carbide create
09:20 PM _unreal_: still trying to figure out how to do the milling stuff in fusion
09:20 PM _unreal_: FINALLY the pocketing task is done
09:20 PM _unreal_: !@#$%!#@$%^@#$%^!#@$ palm to face...
09:21 PM _unreal_: I thought I did someting worng. its ok but I'm starting the two circle cuts from the top so I'm cutting air right now
09:22 PM MarcelineVQ: fusion was pretty straightforward when I was using it, would often get few false-positives on collisions during simulation that I could never quite figure out though
09:26 PM * _unreal_ loves getting pelted by cnc shrapnel
09:29 PM _unreal_: MarcelineVQ, if you have never used starboard. sample some. you'll likely fall in love with it stupid fast
09:30 PM roycroft: well, i found enough food without having to go to market
09:30 PM _unreal_: home depo/lows both sell it
09:30 PM MarcelineVQ: I can't help but think it'd be an expensive material around here but I'll keep me eye open for some
09:31 PM _unreal_: I'm so glad I put the light I have on my cnc
09:31 PM roycroft: so i took a couple pics while thawing some prawns
09:31 PM roycroft: http://www.roycroft.us/Drawer_Pull_1.jpeg
09:31 PM roycroft: http://www.roycroft.us/Drawer_Pull_2.jpeg
09:31 PM XXCoder: maybe im an dumbass, but isnt buying store one cheaper?
09:31 PM roycroft: try to find one at a store
09:32 PM roycroft: wooden drawer pulls are really hard to find
09:32 PM roycroft: and they're usually pretty crappy when you do find them
09:32 PM roycroft: and expensive
09:33 PM roycroft: plastic and stamped metal is what folks use these days
09:34 PM roycroft: i know you missed the beginning of this discussion
09:34 PM roycroft: but i spent a bunch of time trying to buy some drawer pulls before i decided just to make them
09:34 PM _unreal_: XXCoder, obviously your a dumb ass
09:34 PM XXCoder: erm I dont own a dumb?
09:34 PM roycroft: or xxcoder hasn't done much drawer pull shopping
09:34 PM MarcelineVQ: ohho neat design, that is straightforward enough to cut in one setup on a 3 axis.
09:35 PM roycroft: thanks
09:35 PM roycroft: i do like the design - it looks nice to me
09:35 PM XXCoder: makes sense now that I think of it. wood ones tend to be bit pricu
09:35 PM roycroft: and as i said, it's very comfortable
09:35 PM roycroft: i put a lot of meat on the ends, so that when i screw into them the screws will hold well
09:35 PM XXCoder: nice.
09:35 PM Tom_L: u didn't wait.
09:36 PM _unreal_: you shold post the code :)
09:36 PM roycroft: i figure i piqued some folks' curiosity
09:36 PM XXCoder: I wonder if starboard is printable plastic lol
09:36 PM roycroft: and i try not to be a tease :)
09:36 PM roycroft: since i did not have to drive to market for food i had a couple spare minutes
09:36 PM Tom_L: i don't see why you couldn't cnc those
09:36 PM _unreal_: XXCoder, printable?
09:37 PM _unreal_: XXCoder, two color starboard is often used for signs
09:37 PM _unreal_: "etched" signs
09:37 PM roycroft: they would be easy to cnc
09:37 PM XXCoder: oh talking about 3d printing
09:37 PM roycroft: i already explained why i would not do so
09:37 PM roycroft: the fact that i don't have a cnc machine notwithstanding
09:37 PM Tom_L: carry on.
09:37 PM _unreal_: when my cnc moves to the last pocket job I'll snap an other photo
09:37 PM _unreal_: you'll see the quality
09:38 PM _unreal_: I have a TINY spindle motor
09:38 PM _unreal_: and its having no issues
09:38 PM _unreal_: then again I'm taking 1/16 per pass
09:38 PM MarcelineVQ: _unreal_: the two/three color stuff I have seen, it's pretty damn cool being able to to just cut out a sign that'll last for years and years
09:39 PM _unreal_: yep
09:39 PM _unreal_: I build a lot of stuff for the boats from starboard
09:40 PM _unreal_: last week I built a custom bait cutting board for a rod holder setup

09:44 PM _unreal_: have a look at that
09:58 PM _unreal_: I'm uploading a finished part photo right now of what the starboard looks like
10:03 PM _unreal_: https://drive.google.com/open?id=1E4JtXZya1bMm-9be6Le2g-1w3dUFu1jl
10:04 PM _unreal_: just finished milling
10:10 PM MarcelineVQ: neat stuff
10:13 PM Rab: _unreal_, interesting stuff. How rigid is it, esp when it gets warm (e.g. in direct sunlight)?
10:14 PM XXCoder: how UV resistant is it?
10:14 PM _unreal_: very
10:14 PM Rab: King StarBoard® has a matte finish on both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King StarBoard® will not rust, delaminate or rot when exposed to UV, humidity or water.
10:14 PM _unreal_: and very
10:15 PM _unreal_: XXCoder, its often used to make fishing rod holders. scroll style. its used as cutting boards. food pads for stepping on. steps on ladders.
10:15 PM Rab: _unreal_, is it heavy?
10:15 PM _unreal_: landing pads for outboard tenders
10:15 PM XXCoder: cool
10:15 PM _unreal_: Rab, it can get heavy yes
10:15 PM XXCoder: how millable is it? is it as nasty as nylon?
10:16 PM _unreal_: look at my photos
10:16 PM _unreal_: its very clean
10:16 PM Tom_L: should mill easy
10:16 PM _unreal_: depending on your cutting method
10:16 PM XXCoder: not bad.
10:16 PM _unreal_: it makes small chips
10:16 PM XXCoder: tried with nylon it didnt go well. theres yt video if youre curious lol
10:16 PM _unreal_: starboard is a DREAM to work with
10:16 PM Rab: _unreal_, looks very clean in the pics. Is that a 1/8" carbide 2-flute end mill, or something else/
10:17 PM _unreal_: Rab, that exactly
10:17 PM _unreal_: made by vermont american
10:18 PM _unreal_: its very easy to get a clean finish and easy to get a polished finish. great for making molds with
10:20 PM Rab: _unreal_, thanks for the evangelism, just ordered a piece from eBay.
10:21 PM Rab: Easy to get a polished finish? By sanding, flame polishing, or some other method?
10:21 PM CaptHindsight: HDPE magic
10:21 PM _unreal_: I'll have a finished part photo uploaded in a min.
10:21 PM CaptHindsight: yes
10:21 PM _unreal_: or right now https://drive.google.com/open?id=1E5-rpmLg5HROr4s4sXaLNg5hOAigbYnE
10:21 PM _unreal_: you can sand it smooth sand/buff
10:22 PM _unreal_: you can heat smooth but not as good in the rusults
10:22 PM _unreal_: results
10:22 PM CaptHindsight: melt the sawdust down and reuse
10:22 PM _unreal_: I've never tried flame smoothing on it... I'll admit
10:23 PM _unreal_: but I would assume it may mess with the UV stability
10:23 PM CaptHindsight: flame also raises the surface energy to bond printing inks to it better
10:23 PM Rab: HDPE has generally good solvent resistance, wonder how StarBoard® holds up.
10:23 PM CaptHindsight: starboard is HDPE
10:23 PM Rab: Yes, with additives.
10:23 PM CaptHindsight: yes, most hdpe is not 100% hdpe
10:24 PM CaptHindsight: unless you order 100% hdpe pellets
10:24 PM _unreal_: Rab, starboard handles acetone like a champ
10:24 PM CaptHindsight: hydrofluoric acid
10:24 PM Rab: CaptHindsight, while what you say is surely true, I'm specifically wondering about Starboard.
10:24 PM _unreal_: CaptHindsight, no idea
10:26 PM CaptHindsight: fillers are things like clay, glass, sand in various forms
10:26 PM CaptHindsight: fiber, beads, bubbles etc
10:27 PM _unreal_: So damn cool to finally have the parts for my dust collection
10:27 PM _unreal_: makes life way easyer
10:27 PM _unreal_: well will when its ready
10:28 PM _unreal_: I'm going to use some isinglass for the front so I can at least see the cutting bit while its working
10:31 PM Tom_L: how do the arc quadrants measure out?
10:31 PM _unreal_: huh?
10:31 PM Tom_L: after you fixed the axis
10:31 PM Tom_L: are the circles round?
10:31 PM _unreal_: they where round before. mainly my Z pitch was off
10:31 PM Tom_L: k
10:32 PM _unreal_: My Y to X was out by 1mm at the far ends
10:32 PM XXCoder: new primative tech https://www.youtube.com/watch?v=YmFTK-rnzfk
10:33 PM _unreal_: my biggest issue is that my guides for Z where pitched so the top of the Z was leaning fwd
10:33 PM _unreal_: and the bottom was aft
10:33 PM _unreal_: it was out by I believe 1.5 degree's
10:33 PM _unreal_: enough that is was very noticable
10:33 PM Tom_L: yeah
10:34 PM _unreal_: and made milling very hard to do in parts that were deeper then 1/4"
10:34 PM _unreal_: especially circles
10:35 PM _unreal_: fine on everything but the aft end or the + side of the x into Y into x stroke doing circles
10:35 PM _unreal_: it would start to bind
10:36 PM _unreal_: I just did a .5" deep 1/8 bit milling no binding
10:36 PM _unreal_: now I just need to glue the magnets into place
10:36 PM _unreal_: I'm torn between gorilla glue and hot glue
10:36 PM Tom_L: not sure what sticks to HDPE
10:36 PM _unreal_: Tom_L, NOTHING
10:37 PM _unreal_: thats the problem
10:37 PM Tom_L: The Loctite All-Plastic Super Glue includes a tube of bonding agent and a bottle of surface activator. It bonds with hard and soft plastic. The glue works well with polyethylene and polypropylene surfaces.

10:40 PM Tom_L: LDPE can be welded to HDPE but not vise versa
10:40 PM Tom_L: The most important rule about welding polyethylene is that you can weld low to high but not high to low. Meaning, you can weld low density polyethylene (LDPE) welding rod to high density polyethylene (HDPE) sheet but not vice versa. ... Like PP, HDPE is weldable at 572F/300C.
10:42 PM _unreal_: there I just gorilla glued my magnets in
10:42 PM _unreal_: I'm saddly fresh out of hdpe glue...
10:46 PM net|: https://i.imgur.com/iFoNAlH.png function name test was to blame then

10:51 PM _unreal_: sigh. tomorrow I have to take my Z spindle mount off so I can drill 4 holes and mount the upper holder
10:51 PM _unreal_: sigh
10:52 PM _unreal_: Then I'll be able to mount the brush.
10:52 PM CaptHindsight: https://www.innerduct.com/hdpe-glue
10:52 PM CaptHindsight: https://www.tamarrontechnology.biz/adhesives/
10:53 PM _unreal_: I'm not sure how I want to mount it though. I'm thinking I may try velcrow? or just drill holes and use something as a backer to hold the brush on?
10:53 PM _unreal_: dont know

10:55 PM * _unreal_ is so happy with his DIY cnc
10:55 PM XXCoder: :)
10:56 PM _unreal_: LOL I've been trying to figure out how I could hold he magnets down in my part I milled so the clue can set
10:57 PM _unreal_: it just dawned on me "DUH DUMB ASS" there magnets. put it on something metal and it will pull the magnets into place
10:59 PM _unreal_: tomorrow after the glue has dired. I'll drive some hot glue into the gaps
10:59 PM _unreal_: if the gorilla glue doesnt expand to much and fill themn
11:03 PM MarcelineVQ: if you mill a rough bottom in the holes glue might hold a little better
11:04 PM MarcelineVQ: or maybe just whip a scribe along the bottom untill it fluffs up a bit
11:04 PM MarcelineVQ: doesn't help that magnets are slipepry too
11:11 PM _unreal_: I got some home depo magnet packs
11:11 PM _unreal_: those things are very rough
11:11 PM _unreal_: clear saw marks
11:12 PM _unreal_: this thing should hold great
11:12 PM MarcelineVQ: dang, magnets work better smooth
11:12 PM _unreal_: ?
11:13 PM _unreal_: the face is smooth but the sides are rough
11:13 PM _unreal_: they have plenty of grab
11:13 PM roycroft: duct tape is the answer
11:14 PM _unreal_: at least someone has some common sense around here
11:23 PM roycroft: or at least several rolls of duct tape and a strong will
11:25 PM MarcelineVQ: the specialist kit: duct tape, a heat gun, and the earwax of 3 midgets
