02:23 AM XXCoder: 3d printing alum. "meld" https://youtu.be/R0g-qhCoTIQ
02:30 AM XXCoder: and other metals
02:34 AM Deejay: moin
05:18 AM JT-Cave: morning
07:33 AM Loetmichel: <- is just cleaning up his hobby room... Is it normal to find a stack of 7 notebooks and 3 tablets while cleaning? ... OH, the one i grabbed first has Vista on it... and avira is complaining about "1480 days no updates"... i REALLY should sort the stuff here more often :)
07:34 AM CloudEvil: No.
07:36 AM Loetmichel: no to the stack or no to the more often cleaning?
07:38 AM CloudEvil: I mean, I think I have at least 24 laptops and a dozen tablets in various states of functionality.
07:44 AM Loetmichel: I have more, most in working contdition, just found those 7 that i totally forgot about.
07:56 AM Tom_L: morning
08:02 AM Loetmichel: hehe, next one: Acer 17" with an I5-2.3ghz and 4gb ram... and an ubuntu 12.04 installed... Battery says 8.2V though, a bit low for a 9 cell :(

08:39 AM t4nk_freenode: just made my first steps trying to mill the microSD
08:40 AM t4nk_freenode: ...
08:40 AM t4nk_freenode: what can I say ;)
08:41 AM t4nk_freenode: used some 5nm endmill
08:41 AM t4nk_freenode: euh... .5mm :b
08:41 AM t4nk_freenode: set zero on it..
08:42 AM t4nk_freenode: wanted to move slowly, bt typed g0
08:42 AM t4nk_freenode: 'but'
08:42 AM t4nk_freenode: snapped incredibly fast
08:43 AM t4nk_freenode: then the second bit... took it easy, but it snapped on me too
08:43 AM t4nk_freenode: anyhow, I ended up just using what was left of the bit to do the contour
08:43 AM t4nk_freenode: and I must say that it's brilliant
08:44 AM t4nk_freenode: I also planed the pcb to the right thickness
08:44 AM t4nk_freenode: it fits like a charm
08:45 AM t4nk_freenode: the traces... is a whole different animal
08:47 AM t4nk_freenode: it's gonna take me a few more tries I reckon, but I guarantee you that I;'ll pull it off
08:50 AM * JT-Cave wonders why debian 11 astral repo is still at 1.7 and not 2.2
09:05 AM t4nk_freenode: (I'll also step away from it and sleep on it again ;) )
09:16 AM JT-Cave: hmm tkinter is no longer installed on debian 11 by default
10:04 AM Tom_L: they just like to keep ya guessing
10:18 AM _unreal_: t4nk_freenode, I told you before you can go no more then 26-50mm/min with the .5mm bits and you can go no deeper then the width of the bit which is .5mm
10:19 AM _unreal_: per pass
10:19 AM _unreal_: any faster and they will snap
10:21 AM t4nk_freenode: I had step down set to a modest .2mm
10:22 AM _unreal_: t4nk_freenode, those .5mm bits REALLY want to be running 24k-60k rpm. My cnc machine I can mill PCB's at about 100mm/min running 15k rpm
10:22 AM t4nk_freenode: mmmm I was well below 12k
10:22 AM _unreal_: ???????????????
10:22 AM t4nk_freenode: anyhow, my feed was 300mm/min, which I thought was slow
10:23 AM _unreal_: HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA hardly
10:23 AM t4nk_freenode: and I went to 200mm/min after that
10:23 AM _unreal_: rasp's want HIGH rpm, and slow feed
10:23 AM _unreal_: t4nk_freenode, start slow and work up
10:23 AM _unreal_: kind of common sense !!!!
10:24 AM _unreal_: I broke a .5 bit once just because there was contamination IN a pcb below the copper
10:25 AM _unreal_: dumb founded me
10:37 AM roguish[m]: just found out one of my local machine shops moved to Idaho............. he escaped.............coool for him.
11:18 AM JT-Shop: one running board installed one to go...
11:41 AM _unreal_: there and with that all 3 of my stm32f401 boards have been soldered (added jst pins)
11:43 AM _unreal_: Next I need to solve GRBL/pinout for these and then to design a PCB board to convert this STM32F401 to arduino uno foot print.
11:43 AM _unreal_: then my upgraded stm32 GRBL can happen for my laser etcher
11:56 AM unterhausen: my package got shipped by fedex, hopefully it doesn't end up in the woods
12:01 PM roycroft: the parcel i'm anxiously awaiting - the one shipped by this aqualine outfit i'd never heard of - departed portland two days ago
12:02 PM roycroft: i just got an update that delivery was "delayed", and it is now in anchorage
12:02 PM roycroft: that's an odd place for a layover
12:02 PM _unreal_: alaska?
12:02 PM roycroft: yes
12:02 PM roycroft: portland is an hour and a half north of here
12:03 PM roycroft: i think my parcel went in the totally wrong direction
12:03 PM roycroft: i was hoping to receive it today - it is the spindle mount for my cnc router
12:03 PM roycroft: and i don't have accurate dimensions for it, so i need the bracket itself to measure before i can draw the z axis
12:04 PM JT-Shop: some guy just bought all my 7i77 cards
12:04 PM roycroft: sounds like you don't have enough inventory
12:04 PM JT-Shop: no one does
12:05 PM roycroft: this is what happens when jit manufacturing runs into snags
12:05 PM roycroft: it starts a cascade of sadness
12:06 PM JT-Shop: the spartan 6 chip has a lead time of >52 weeks!
12:06 PM JT-Shop: I don't think that is a jit issue
12:06 PM roycroft: my spindle mount originated in florida, btw
12:06 PM roycroft: it got all the way across the country just fine
12:07 PM roycroft: but then it kept going
12:09 PM roycroft: oh well
12:10 PM roycroft: i have plenty of other things i can be doing, but i have finally decided on how i am going to build my router, and would really like to start making drawings
12:10 PM roycroft: of course, that is the one component for which i don't have good dimensions, and it needs to be part of the first drawing set

12:33 PM robotustra: good dat
12:33 PM robotustra: day
12:34 PM roycroft: well, it's a day at least
12:35 PM roycroft: its goodness is not intrinsic, but i aim to make mine good
12:35 PM robotustra: https://imgur.com/a/wVimf4R
12:36 PM robotustra: learning how to turn
01:04 PM jdh: on what?
01:05 PM robotustra: on my mill
01:06 PM robotustra: manual yet
01:15 PM robotustra: err, on my LATHE
01:15 PM robotustra: :)
01:16 PM robotustra: jdh, https://www.youtube.com/watch?v=W1PRMQqAZ0E
01:19 PM robotustra: trying to do some precise dimetions on it. So far so good. Can achieve 0.02 mm
01:19 PM robotustra: on small parts of cause
01:26 PM robotustra: step is 0.005 mm theoretical
01:26 PM robotustra: but I'm not sure in the rigidity
01:27 PM robotustra: I can't move the toolpost with respect to chuck even in 0.01mm
03:51 PM JT-Shop: customer "I think this 5i25 is broken, I plugged it in and can't find the second parallel port"
04:36 PM robotustra: I think this customer is broken either
04:40 PM Tom_L: JT-Shop, you should have shipped one with the extra pp
04:41 PM JT-Shop: they have to flash a pp on it lol
04:41 PM Tom_L: is that the one with the 2 26 pin headers?
04:42 PM Tom_L: one db25
04:43 PM Tom_L: ridgeline with 2 running boards now?
04:45 PM JT-Shop: aye DB25 on the back and a 26 pin IDC on the side
04:45 PM JT-Shop: yup, just need to install the Bedrug and she's set
04:45 PM JT-Shop: still shuffling crap to make room
04:45 PM Tom_L: we got those rubber mats for the kids and her car
04:46 PM Tom_L: sure glad too, they usually come home full of aluminum chips
04:46 PM JT-Shop: the Ridgeline came with the Ridgeline rubber mats
04:47 PM Tom_L: i'm not sure, these may be honda branded
04:48 PM Tom_L: that or weathertech
04:48 PM JT-Shop: my dealer puts honda rubber mats in all the vehicles they sell
04:49 PM Tom_L: i think these did too but we upgraded since these have the sides built up a bit more
04:49 PM Tom_L: pretty sure anyway
04:50 PM Tom_L: no, the stock ones were carpeted on the civics
04:51 PM Tom_L: i remember now since one kid still has his in the back hatchback
04:52 PM Tom_L: the stock ones that is
04:52 PM JT-Shop: my dealer puts the carpet in the truck of cars
04:53 PM Tom_L: hers came with mud flaps from another dealer
04:53 PM Tom_L: they brought it in for her
04:53 PM Tom_L: didn't necessarily want them but meh
04:55 PM robotustra: Tom_L, how is everything/
04:56 PM robotustra: ?
04:58 PM enleth: do you know what the VHM designation for carbide in some tool specs actually stands for, letter for letter?
05:00 PM Tom_L: good
05:03 PM Tom_L: https://www.federalcarbide.com/tungsten_carbide_grade_chart.html
05:03 PM Tom_L: enleth, is that what you're asking?
05:04 PM Tom_L: https://www.federalcarbide.com/tungsten_carbide_grade_comparison_chart.html
05:06 PM Tom_L: https://www.generalcarbide.com/wp-content/uploads/2019/04/GeneralCarbide-GradeSpecs.pdf
05:07 PM enleth: none of those contain "VHM"
05:07 PM Tom_L: dunno then
05:07 PM enleth: it looks like this might be a local or vendor-specific designation that for some reason became popular in my area as a synonim for "this tool is made out of carbide"
05:12 PM _unreal_: there just swapped in my new PSU for my micro cyclone dust collector
05:12 PM _unreal_: nice 90W 24v rack style psu
05:13 PM _unreal_: the other psu worked fine but it's 18v this one being 24 it adds a little more rpm but not a lot
05:16 PM robotustra: Tom_L, finished the first part on the lathe today :)
05:19 PM _unreal_: oh 15v not 18
05:20 PM _unreal_: ve7it, you live?
05:23 PM Tom_L: robotustra, saw that
05:23 PM Tom_L: nice one
05:29 PM robotustra: Tom_L, it was not finished yet, this is finished one: https://imgur.com/a/HLjv90H
05:30 PM Tom_L: what's the bushing for?
05:31 PM robotustra: I want to fix the gear I made, the concentricity of the gear is off for about 0.5mm
05:31 PM robotustra: I want to remove inner part, but the bushing and river it
05:35 PM robotustra: the gear was done purely on the mill that's why it was an issue with central orifis
05:35 PM Tom_L: you made the gear?
05:35 PM Tom_L: i think i remember that
05:37 PM robotustra: yes I did a couple of them, but as soon as I understand the blanks should be done on the lathe to get the best result
05:38 PM robotustra: to cut teeth on mill after
05:52 PM _unreal_: LOL CNN fires cuomo
06:04 PM solarwind_: https://youtu.be/-4A3lQBM80o?t=961 Did he TIG braze the 40 taper arbor onto that lathe chuck?
06:04 PM solarwind_: Because that would indeed give you very large swing on a horizontal mill
06:05 PM solarwind_ is now known as solarwind
06:06 PM solarwind: It made the arbor all hot and likely changed its hardness, but I think silicon bronze TIG brazing is a good choice for something like that, no?
06:33 PM _unreal_: t4nk_freenode, so have you tried again with a SLOWER feed/speed
06:50 PM ve7it: _unreal_, nice you found a possible source for more sat dishes. I might be able to help some with your project, but I am really busy at the moment trying to become proficient in fpga programming... a huge time sink but one can do very cool stuff
06:51 PM ve7it: Its quite possible what you need to do could be handled by a mesa board.. most of the work is already done by magic in the fpga!
06:53 PM ve7it: Let linuxcnc do the servo positioning loop.
07:23 PM solarwind: I wonder how long it takes for a dewar of liquid argon to fully boil off
07:24 PM CloudEvil: Argon is of the same order of magnitude as nitrogen and oxygen. Modest sized (25l) lab dewars will hit a yearish
07:24 PM solarwind: That is, in a sealed storage state with only the pressure relief valve
07:24 PM CloudEvil: They typically are at atmospheric pressure
07:24 PM solarwind: CloudEvil WOW they last _that_ long?!?
07:24 PM CloudEvil: yes
07:25 PM solarwind: Why the hell am I paying so much to refill my argon cylinders!? I can buy a cryocooler on ebay for $1,000
07:25 PM CloudEvil: https://www.coleparmer.co.uk/i/cole-parmer-polarsafe-cryogenic-storage-dewar-115l-with-6-x-6-layer-racks/4426055
07:26 PM CloudEvil: Liquid nitrogen could also be used to chill liquid argon.
07:26 PM solarwind: I plan to argon ALL THE THINGS. Huge champagne gas lens, even for electronics soldering
07:26 PM solarwind: Yeah that was the plan
07:26 PM solarwind: https://www.youtube.com/watch?v=7PWESWqhD8s
07:26 PM CloudEvil: Getting argon gas from air is not trivial
07:27 PM solarwind: I know, but I would use the cryocooler just to eliminate it from venting into the atmosphere
07:27 PM CloudEvil: Getting it reliably in large quantities in an automated manner
07:27 PM CloudEvil: ah
07:28 PM solarwind: I love Ben Krasnow from Applied Sciences. Smart guy with very expensive equipment. I envy his $20,000 MSO: https://www.tek.com/oscilloscope/5-series-mso-mixed-signal-oscilloscope
07:28 PM solarwind: That's my dream MSO
07:31 PM solarwind: CaptHindsight[m] wink wink. My birthday is in a month
07:47 PM solarwind: I opened a can of coke with the intention of using it to clean the copper sulfate off some copper clamps but ended up drinking it :(
08:06 PM CloudEvil: Does urine dissolve copper sulfate?
08:17 PM roycroft: it causes the formation of copper sulphate on brass
08:21 PM _unreal_: ve7it, cool. sorry I was working on a clients project...
08:22 PM _unreal_: gave me a mother @%@#@#$ graphic to be converted into a drink coaster
08:29 PM _unreal_: the problem is that I couldnt use the jpeg because it had "shading"
08:40 PM roycroft: if any of you folks use an 80mm 24krpm spindle for your cnc routers, do you use the air-cooled version or the water-cooled version?
08:41 PM roycroft: i have a water-cooled one in my router table, because the dust gets sucked straight down over the end of the spindle
08:41 PM _unreal_: 80m?
08:41 PM roycroft: 80mm
08:41 PM roycroft: 80m would be a pretty huge spindle
08:42 PM roycroft: on the cnc router, the dust shoe would pull the dust off to the side and then up - i shouldn't think the spindle end would get too much dust
08:42 PM _unreal_: so your talking about a 2.2kw spindle
08:42 PM roycroft: yes
08:42 PM roycroft: there are others that are 80mm in diameter
08:42 PM roycroft: but i'll be getting a 2.2kw one
08:42 PM _unreal_: depends on use. but most would have a water cooled setup
08:43 PM roycroft: that adds complications
08:43 PM _unreal_: air cooled typically have a big square CAN around the motor
08:44 PM roycroft: yeah, i've seen some air cooled ones with the big square can
08:44 PM roycroft: but i've also seen them with the same 80mm collar
08:44 PM _unreal_: a 2.2kw makes a shit load of heat
08:44 PM _unreal_: better to water cool it unless it has the big CAN on it
08:45 PM _unreal_: what is the reason behind the question?
08:46 PM roycroft: i need to decide which to get
08:46 PM _unreal_: water cooling isnt hard at all
08:47 PM roycroft: installation of an air cooled would be a lot simpler, because i won't have to route water hoses
08:47 PM _unreal_: and you got two choices. tiny radiator on the spindle. or run lines in the drag chains
08:47 PM roycroft: i also don't want to have to install a second pump and water tank
08:47 PM roycroft: but i could probably share the coolant tank with my router table
08:48 PM roycroft: and probably even the same pump, if i add some valves to switch between spindles
08:48 PM _unreal_: my big system that is still on hold is setup with a water cooled 1.5 kw and I just ran lines
08:48 PM roycroft: or just always run coolant through both spindles
08:48 PM _unreal_: its a closed loop water cooling
08:48 PM _unreal_: just goes to a 2gal bucket
08:48 PM roycroft: it doesn't hurt to run coolant through a spindle that is not running
08:49 PM _unreal_: its just a "jacket"
08:49 PM _unreal_: water jacket
08:49 PM roycroft: https://www.amazon.com/ACCURA-Vertex-coolant-system-lathes/dp/B000HEUYIM
08:49 PM roycroft: i have one of those in my router table currently
08:50 PM _unreal_: wholy crap thats huge and expensive
08:50 PM roycroft: i'm sure i can run two spindles with it
08:50 PM _unreal_: easy
08:50 PM roycroft: it wasn't nearly so expensive when i bought it
08:50 PM roycroft: i purchased it in the before times
08:50 PM _unreal_: my setup has a tiny fish water pump and its MORE then enough
08:50 PM roycroft: before the previous president and his bullshit tariffs time, even
08:51 PM roycroft: iirc i paid just over $100 for it at the time
08:51 PM _unreal_: for what it is not bad at all for a far more robust device
08:52 PM roycroft: and it runs on 240v, which is the power i have at the router table
08:52 PM roycroft: if i got a tiny pump i'd need to drop the voltage down to 120v for it, and the transformer would cost about as much as the pump
08:53 PM roycroft: i've never used an air-cooled version of that spindle
08:54 PM roycroft: perhaps it's best to just stick with water-cooled
08:54 PM roycroft: if for no other reason that i would not have to stock a spare - if the spindle died in the middle of a job i could repurpose the router table spindle
08:54 PM _unreal_: a thing to keep in mind is the air cooled one's blow from top down. and have issues with using a dust shoe
08:55 PM roycroft: i wondered about that
08:55 PM roycroft: if they blew from the collet end up there would be dust problems
08:55 PM roycroft: the other way, and you're blowing air down into the dust cloud that the extractor is trying to suck up
08:55 PM roycroft: the turbulence would probably cause problems
08:56 PM _unreal_: some blow down past the spindle shaft. some vent at the side. regardless a dust shoe is in the way
08:56 PM _unreal_: they also do make a bit more noise do to the fan
08:57 PM t4nk_freenode: love, love me due
08:57 PM roycroft: i have not gotten to the point of designing the dust shoe yet, but anticipate it will clamp over the end of the spindle, be oval shaped, and will have an extraction hole on the top of the dust shoe next to the spindle
08:57 PM roycroft: that is how most folks seem to make them
08:57 PM _unreal_: roycroft, dont forget to consider an option for an air assist jet so you can clear your chips as your milling
08:58 PM roycroft: i'm not sure i'll need that
08:58 PM _unreal_: think 1/8-3/16 pipe that can be aimed at the cutting bit.
08:58 PM roycroft: i'm still thinking about how to cut cleanly
08:58 PM _unreal_: depends on what your milling
08:59 PM _unreal_: if you cut aluminum or anything that can and will pack chips in the cut groove you will want it.
08:59 PM roycroft: one thought, keeping i mind that i'll be doing mostly cookie-cutter type stuff in sheet goods, is to start with a spiral down cutter, and make a clean, shallow cut in the top of the part
08:59 PM t4nk_freenode: alumunum! ;)
08:59 PM roycroft: then switch to a spiral up cutter to finish cutting through the part
08:59 PM _unreal_: what material thickness?
08:59 PM roycroft: that would leave clean edges top and bottom
09:00 PM _unreal_: wait WHAT?
09:00 PM roycroft: and as most of the work would be with the up cutter, chips would not tend to accumulate
09:00 PM _unreal_: down cut with out cutting all the way through?
09:00 PM roycroft: yes, down just for the first mm or so
09:00 PM roycroft: just to break the edge
09:00 PM _unreal_: O,O ahhhhhhhh
09:01 PM _unreal_: you would be better off with a straight two flute if your doing that
09:01 PM roycroft: perhaps
09:01 PM _unreal_: a down cut should only be used when the bit is cutting all the way though the material
09:01 PM _unreal_: other wise you are going to drive your bit to be impacted
09:01 PM roycroft: the important thing is to not use an up cutter for the initial pass, as it would tear the hell out of the wood
09:01 PM _unreal_: agreed
09:02 PM roycroft: and i don't think i'll mind having to do a tooling change
09:02 PM _unreal_: by that description alone a straight would be your best choice
09:02 PM roycroft: it should be pretty quick to do
09:02 PM roycroft: a straight cutter is 1/3 the cost of a spiral down cutter anyway
09:02 PM _unreal_: better to do a shallow pass on the first cut to break the surface, far less risk of tearing
09:02 PM roycroft: and if it works as well, or better, then it would be perfect
09:03 PM roycroft: for a cnc router, i think a compression cutter is kind of a dumb idea
09:03 PM roycroft: those things are so bloody expensive
09:03 PM _unreal_: You can also "mask the surface with blue masking tape (#2020) tape 2"
09:04 PM _unreal_: will also greatly reduce the risk of tear out
09:04 PM roycroft: yeah, i do that on the table saw sometimes
09:04 PM _unreal_: compression cutter?
09:04 PM roycroft: masking tape
09:06 PM _unreal_: I dont know what a router "compression cutter" is?
09:06 PM _unreal_: got a link?
09:06 PM roycroft: it is a combination upcut and downcut in the same cutter
09:07 PM _unreal_: Oh you mean down cut
09:08 PM roycroft: https://www.whitesiderouterbits.com/collections/up-down-cut-spiral-bits-three-flute/products/ud5123
09:08 PM roycroft: no
09:08 PM roycroft: it combines both
09:08 PM roycroft: it's downcut at the router end, and upcut at the far end
09:08 PM roycroft: so you get clean cuts on both sides of the board
09:08 PM _unreal_: ya those expect you to be cut all the way though the material
09:08 PM roycroft: yes
09:09 PM _unreal_: float the "middle"
09:09 PM roycroft: and they're wicked expensive
09:09 PM roycroft: with a hand-held router they may make sense
09:09 PM XXCoder: honestly down is enough. just have something under material you dont care about
09:09 PM roycroft: but in a cnc router, you can take multiple passes, and swithc tooling
09:10 PM _unreal_: GOD I did a job this past week using my finish router.... all anyone had was 1/2" guided straight flutes. I needed a 1/4" guided. with a high side bearing.....
09:10 PM roycroft: i've never bought a compression cutter
09:10 PM roycroft: because they're so expensive
09:10 PM _unreal_: ended up having to use the half inch. GOD DAMN that thing was grabby on starboard(HDPE)
09:10 PM _unreal_: nore have I
09:11 PM _unreal_: a bit like that is only used really for wood or soft materials that can splinter or tear out.
09:11 PM roycroft: and i'd only use it for the final pass
09:12 PM roycroft: so there would be a tooling change anyway
09:12 PM roycroft: use a $40 cutter to get close
09:12 PM roycroft: and only use the $150 one for the final pass
09:13 PM roycroft: and in the context of this discussion, everything i do will be wood
09:13 PM roycroft: i'm sure i'll use the router for non-ferrous metals and plastics at times, but most of the use will be for wood
09:13 PM roycroft: and i'll have whole different sets of cutters for other materials
09:14 PM _unreal_: a spindle like that you can mill steel with it. but you have to lower your RPM to about 12k and use a mist coolent
09:15 PM _unreal_: hell I've done STEEL on my homemade machine.
09:15 PM _unreal_: not fast at all but it works
09:15 PM _unreal_: hell aluminum is blazing fast on my machine compaired to milling steel
09:17 PM _unreal_: if your dealing with non partical materials I would not even bother with the most expensive bits. they will not wear out fast.
09:21 PM * Bleepshop wonders where to find some 12x24x0.75 aluminum bar stock...
09:21 PM _unreal_: that would be plate not bar stock
09:21 PM _unreal_: LL
09:21 PM _unreal_: lol
09:23 PM roycroft: there's always onlinemetals.com
09:24 PM roycroft: their prices are not out of line
09:24 PM Bleepshop: Well, The new spindle/VFD kit is ordered and i'm thinking about tracking down some stock to make a new set of gantry riser plates and increase my Z from ~2" to 8"
09:24 PM roycroft: shippingets pretty expensive, though
09:24 PM Bleepshop: 12x24x0.75 is <25lbs.
09:24 PM t4nk_freenode: so, _unreal_, you got your stm32s two days ago... got it up and running yet?
09:24 PM roycroft: if you were in my part of the world i'd say go to coyote steel here in eugene
09:24 PM Tom_L: inch or mm?
09:25 PM _unreal_: I got the pins soldered on
09:25 PM Bleepshop: Inch. LOL
09:25 PM _unreal_: software is always the problem
09:25 PM roycroft: i'm figuring inches, given the units and given that he's talking pounds
09:25 PM roycroft: 12x24x0.75mm would be sheet metal
09:25 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/7.jpg
09:25 PM roycroft: and would only weigh a few grams
09:26 PM Tom_L: my local surplus
09:26 PM Bleepshop: roycroft: You're in fricking Eugene? Does Springfield still stink like Union Carbide farted on a bad day? xD
09:26 PM roycroft: i tend to stay away from springtucky
09:26 PM roycroft: but the mill that produced the majority of the stench burned down a few years ago
09:26 PM Bleepshop: roycroft: I used to live at 13'th and Hilyard. LOL
09:27 PM roycroft: when you were at the u of o?
09:27 PM Bleepshop: Yeah, Like 35 years ago. LOL
09:27 PM roycroft: i'm in west eugene, at the very edge of town
09:28 PM Bleepshop: Dad was born up at Oakridge and I spent a lot of summers up there.
09:28 PM roycroft: i've been to oakridge many times
09:29 PM roycroft: when i was a systems adminstrator for the freenet we had a modem bank in oakridge, and i was frequently going up there to fix it
09:29 PM roycroft: other than that, oakridge is just a town on the way to the pass
09:30 PM Bleepshop: Granddad was the millwright for the sawmill up there for > 40 years. Lot of lumber came through there.
09:30 PM roycroft: i used to go to the coast more often than i went to springfield
09:31 PM Bleepshop: What's funny is I'm working for a sawmill now and teaching them tricks I learned as a kid. LOL
09:31 PM roycroft: but then the eugene woodcraft store moved to springfield, so i do go over there once/month or so
09:32 PM Bleepshop: I had relatives in Springfield. I had even more reasons to stay hte hell away from there. xD
09:32 PM roycroft: i've lived here for 25+ years, and it's changed dramatically in that time
09:32 PM roycroft: if you haven't lived here for 35 years you would hardly recognize the down
09:32 PM roycroft: town
09:36 PM Bleepshop: I was part of the crew that used to annoy the PD by commiting totally legal acts in a surreptitious manner. Like rolling [Zig-Zag paper in a 15' roll] massive cigars of pipe tobacco from Lazar's Bazaar and sitting on the fountain smoking them at 2AM.
09:37 PM roycroft: lazar's is still around
09:37 PM roycroft: lazar ran for mayor a few years ago even :)
09:39 PM Bleepshop: Getting tickets for obstructing the flow of traffic... At 42MPH... in a 30PMH zone... On a bicycle... Pointed out to the judge that the cop had gone after the easy target as I was the slowest thing hauling ass through downtown... LMAO
09:56 PM * Bleepshop does the Happy Dance that the new spindle will be here Thursday and the Hurry The Hell Up Dance because he's impatient...
09:57 PM roycroft: i'm looking at spindles right now
09:57 PM roycroft: all this stuff has gone way up in price
09:59 PM Bleepshop: I ordered one of these and the 4 year replacement plan. Boy are they gonna lose money if I can get hold of enough stock. LOL
09:59 PM Bleepshop: https://www.amazon.com/gp/product/B078J5CXP3
10:01 PM roycroft: i'm looking at that same spindle
10:01 PM roycroft: i won't get the bundle though
10:01 PM Bleepshop: Also a short set of ER20 collets, an ER20 wrench and the 2meter display extension.
10:01 PM roycroft: my mains are single phase, so i need a 3kw vfd to run a 2.2kw spindle
10:03 PM Bleepshop: I'm just going to de-rate it to 1500W so I have a nice safety buffer or the ability to run at 125% for short runs.
10:03 PM roycroft: i have a panel extender on two of my vfds
10:03 PM roycroft: the cnc router won't need one, though, because i won't be using the panel
10:04 PM roycroft: i'll let linuxcnc control it
10:05 PM Bleepshop: I'm going to remote it at the back of the machine, I won't be able to reach it, but Ill be able to see it from all 3 sides of the table.
10:06 PM Bleepshop: Plus I'm testing the VFD as a possible for ordering at work. Boss advanced me 1/2 of the cost of what I ordered last night and told me to keep him posted on how it works.
10:07 PM roycroft: i have several huanyang vfds, and i've been very happy with them
10:07 PM roycroft: i had one blow up a few months ago, but that's because the motor failed
10:07 PM roycroft: other than that, they just work
10:07 PM Tom_L: seems you can get that with 3 or 4 bearings
10:08 PM roycroft: yes
10:08 PM roycroft: get the 4 bearing spindle
10:08 PM Tom_L: https://www.amazon.com/Huanyang-Spindle-Milling-24000RPM-Engraving/dp/B077BTW4NQ?ref_=ast_sto_dp&th=1
10:11 PM Bleepshop: This is supposed to be the 4 bearing and Huangyang Electrical seller on Amazoink has good ratings for the last couple of years.
10:12 PM roycroft: i've been very pleased with huanyang - their customer service is great, and their products work well
10:12 PM roycroft: i just bought a vfd for my mill - the new gt series, with the higher low-end torque
10:13 PM roycroft: i ordered a 2.2kw vfd for my 2hp motor
10:13 PM * Bleepshop finishes constructing a Subaru tie-rod measuring tool.
10:13 PM roycroft: huanyang could not deliver it in a reasonable timeframe, so they offered to send me a 3kw model instead for the same price
10:13 PM roycroft: i did not turn down their offer
10:13 PM Bleepshop: roycroft: Maybe I'll get lucky too ?
10:14 PM roycroft: they are good and fast at answering questions about applications and configurations
