04:07 AM Tom_L: morning
05:07 AM JT-Cave: morning
05:08 AM XXCoder: heys
05:28 AM Deejay: noon
08:11 AM _unreal_: hello
08:11 AM tiwake[m]: oi
08:12 AM _unreal_: ordered a psu for my new little vacuum
08:12 AM _unreal_: that should arrive tomorrow "should"
08:12 AM _unreal_: thank you amazon
08:12 AM tiwake[m]: screw amazon
08:12 AM _unreal_: no argument
08:12 AM _unreal_: just faster then china
08:13 AM tiwake[m]: there is a local electronics component store here
08:13 AM tiwake[m]: ...somehow
08:13 AM _unreal_: hum
08:13 AM _unreal_: heh use to have a radio shack few years ago 5min down the rode
08:14 AM _unreal_: road
08:14 AM tiwake[m]: pretty neat really... they have ICs, resistors, capacitors, power transistors, and all kinds of other things
08:14 AM _unreal_: if this clamp art is the right size then I print the rest of the body AGAIN
08:14 AM _unreal_: :/
08:14 AM _unreal_: with luck it will fit
08:15 AM _unreal_: really..
08:15 AM _unreal_: years ago when I lived in maine, there was a place I would go to now and then
08:15 AM _unreal_: NTE outlet
08:15 AM tiwake[m]: I bought a little switching bench power supply from them
08:15 AM _unreal_: but it was a bit of a hike to drive to
08:16 AM tiwake[m]: I'm gonna shower'n stuff
08:16 AM _unreal_: I want details :S
08:31 AM CloudEvil: Soluble coolant at 120PSI.
08:37 AM Tom_L: tiwake[m], i got the psu for my cnc from my local electronics guy
08:37 AM Tom_L: he used to carry alot of surplus stuff as well
08:38 AM Tom_L: and one of my buds had a store that did NTE
08:39 AM tiwake[m]: oh nice
09:02 AM drozdziak1: Hi, what's a nice way for real-time g-code visualization? The use case is debugging a program I'm writing that is meant to spew out g-code
09:03 AM drozdziak1: eventually over an fdm printer's serial
09:03 AM drozdziak1: just to start out I only need to get movements and constraints right
09:04 AM drozdziak1: recomendations for larger CNC-related communities are also welcome
09:09 AM _unreal_: drozdziak1, are you talking about viewing the "working" view of tooling the gcode? as if it were on the machine?
09:10 AM _unreal_: most softwares that support that are all internal and do not open gcode
09:10 AM _unreal_: the only software I know of off the top of my head that CAN do that is ESTLcam
09:10 AM Tom_L: there are gcode viewers
09:10 AM Tom_L: dunno any free ones off hand
09:10 AM _unreal_: YA THATS the thing
09:10 AM _unreal_: estl is pay for
09:11 AM _unreal_: estl and fusion both do not visuals
09:11 AM _unreal_: I forget if fusion can open gcode
09:12 AM Tom_L: https://ncviewer.com/
09:12 AM _unreal_: thats not linux based ;)
09:13 AM Tom_L: that wasn't stipulated
09:15 AM Tom_L: seems to work too
09:15 AM drozdziak1: Tom_L: Yeah, _unreal_'s hunch is right, I need it on Linux :P
09:15 AM drozdziak1: thanks though
09:16 AM drozdziak1: _unreal_: I need something that I can stream the gcodes to, the real-time interpretation is the key detail I need
09:17 AM Tom_L: https://github.com/topics/gcode-visualizer
09:18 AM Tom_L: a list of them
09:19 AM drozdziak1: Tom_L: This looks promising, thanks again
09:20 AM Tom_L: CaptHindsight[m], seems Alec released a RTAI 5.3.1 ... just got an email about it
09:21 AM -!- #linuxcnc mode set to +v by ChanServ
09:21 AM Tom_itx: https://github.com/NTULINUX/RTAI
09:21 AM Tom_L: for those that like testing RTAI
09:22 AM Tom_L: only AMD64
09:24 AM tiwake[m]: nCNC
09:25 AM tiwake[m]: https://github.com/manahter/nCNC
09:25 AM tiwake[m]: that looks nifty
09:26 AM Tom_L: there was a commercial one we used called nsee packaged with ncpolaris, an acad addon
10:38 AM * JT-Shop tries to remember what he soaked cutting tools in to dissolve aluminum
10:46 AM perry_j1987: muriatic acid / hydrochloric
10:48 AM * JT-Shop wanders into the garage to see what he has
10:48 AM CloudEvil: Lye will work well
10:49 AM JT-Shop: it's coming back to me now that's what I used last time
10:54 AM Tom_L: gummed up on the cutters?
10:54 AM perry_j1987: i know about this from back when i tried to machine some alum from a home depot once i got my first cnc lol
10:56 AM JT-Shop: that is architectural aluminum usually which means soft as butter
10:57 AM perry_j1987: ya it sure was lol
10:58 AM JT-Shop: usually it's 1100 which is very low strength
11:08 AM Tom_L: like bubble gum
11:12 AM JT-Cave: clogged up the slitting saw lol
11:20 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A12_New/A12_Visejaws1.jpg
11:20 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A12_New/A12_Visejaws2.jpg
11:20 AM Tom_L: jaws ready, waiting on woodruff cutter
11:27 AM Tom_L: JT-Shop, even with coolant?
11:36 AM roycroft: well that was interesting
11:36 AM roycroft: i'm just finishing up making a new table saw sled, and attached the fence
11:36 AM roycroft: i lined it up as square as i could, and then used the five cut method to see how far out of square it was
11:37 AM roycroft: the 12" long strip i cut was 0.0045" out of parallel
11:38 AM roycroft: so divided by 4, just over 0.001" out of square
11:38 AM roycroft: i'm not sure i can dial that in any closer
11:38 AM perry_j1987: what are you making Tom_L
11:38 AM roycroft: i'd need a 3 tenths shim, which i don't have
11:39 AM Tom_L: roycroft, do you use a calipers or tape measure to measure wood?
11:39 AM roycroft: calipers
11:39 AM roycroft: tape measures don't measure to thousandths
11:39 AM Tom_L: or yardstick from the lumber yard..
11:39 AM Tom_L: :D
11:39 AM Tom_L: i don't think they give those out anymore
11:39 AM roycroft: and for those of you who don't know the five cut method, you line up the fence as close as you can, then take a square piece of wood
11:39 AM roycroft: cut a thin strip, rotate 90 degrees clockwise, repeat
11:40 AM roycroft: until you've gone all the way around
11:40 AM roycroft: then you rotate once more and cut a strip about 1" wide
11:40 AM roycroft: that strip will multiply the out of squareness 4x
11:40 AM Tom_L: but wood is so expensive to waste!
11:40 AM roycroft: i used a piece of masonite
11:41 AM Tom_L: perry_j1987, parts
11:41 AM roycroft: and cut kerf-wide strips
11:41 AM perry_j1987: lol mr rich over there using wood to measure with :)
11:41 AM roycroft: and will use the leftover piece for something else
11:41 AM Tom_L: yeah i save my cutoff aluminum for all sorts of things
11:41 AM roycroft: i "wasted" about $0.03 worth of masonite :)
11:42 AM Tom_L: perry_j1987, it's a part for a bud in Canada
11:42 AM roycroft: i don't weld on aluminium often, so i save all my cutoffs and use them to refresh my welding skills whenever i need to do so
11:42 AM perry_j1987: ah
11:42 AM Tom_L: i've done several different ones
11:42 AM Tom_L: including a mold to cast a few
12:14 PM roycroft: i had another go at the sled, and now it's 0.0005" out of parallel
12:15 PM roycroft: that's over 12", but still needs to be divided by 4, since it's cumulative error, so effectively unmeasurable
12:16 PM roycroft: and i made the sled out of baltic birch ply, so it probably won't measure differently this afternoon
12:16 PM JT-Shop: Tom_L, no coolant on the bp knee mill
12:17 PM JT-Shop: come on roy you can get it down to 0.0001"!
12:19 PM roycroft: the only way i got it better this time was to clamp down one end of the fence, remove the screw, and tap it lightly with a hammer, then insert a new screw (in a new hole, of course)
12:20 PM roycroft: but it actually is 0.000125" per foot, so i am effectively there
12:20 PM roycroft: and more square than my machinst squares :)
12:20 PM roycroft: i just got lucky in the initial setup - i've never gotten it that close before on the first go
12:24 PM JT-Shop: my first try I never could get it right but I was not using good material, second one only took one correction
12:34 PM Tom_L: JT-Shop, you need a bucket of oil and a paint brush on the BP then...
12:36 PM JT-Shop: I actually have a no spill bucket with a brush but I've not used it in years
12:43 PM _unreal_: JT-Shop, could be worse and have a no spill bucket full of spill :)
12:43 PM _unreal_: ok after a few errors. printing the last part of this blower hose adapter
12:43 PM _unreal_: with luck it will fit
12:54 PM JavaBean: get chance and luck
12:59 PM Tom_L: no luck needed, just accurate measuring and programming
01:00 PM Tom_L: oh wait.. it's a glue gun we're dealing with here!
01:21 PM _unreal_: I think my printer was glitching out?
01:21 PM _unreal_: before
01:21 PM _unreal_: hence the reboot
01:21 PM _unreal_: so my parts are printed and fit nice
01:25 PM _unreal_: ya I think something was going on. just put it together and it seems like the barb part is a hair smaller then it should be.
01:25 PM _unreal_: I've printed others that were almost to large/perfect
01:25 PM _unreal_: soooo.....
01:26 PM _unreal_: wondering if there was some kind of an issue/error with cura and it effecting the printer?
01:26 PM _unreal_: WHO KNOWS
01:26 PM _unreal_: its done. I now have the vacuum parts I need.
01:26 PM _unreal_: just need the PSU to put it together
01:26 PM _unreal_: wondering how its going to be for noise?
01:26 PM _unreal_: I assume LOUD
01:27 PM _unreal_: considering the fact that its a 250watt blower BLDC running at 24v. and the output is 1" ID
01:32 PM perry_j1987: what are you making
01:47 PM * roycroft needs to start making drawers after lunch
01:47 PM roycroft: something i really enjoy doing, i might add
01:47 PM perry_j1987: they sell them in the stores now of days. fruit of the loom is a popular brand
01:48 PM perry_j1987: *wonders why roycroft stil plans eating whatever he's going to eat that he knows will make him need new drawers
01:56 PM JT-Shop: roycroft, what method do you use for the sides?
01:57 PM roycroft: for shop fixture drawers, like these, i use box joints on the fronts and dadoes for the backs
01:58 PM roycroft: and on this cabinet i'll be adding full overlay fronts over the boxes
01:58 PM roycroft: i'm still deciding what kind of pulls to make for them
01:58 PM JT-Shop: do you leave the fingers slightly proud then sand them down?
01:59 PM roycroft: no, not for these - i'll cut them to size and go for a perfect mesh
01:59 PM JT-Shop: makes sense
01:59 PM roycroft: mainly because i barely have enough material
01:59 PM roycroft: after the saw kerfs and squaring up the edges of the plywood, i have no room to oversize them
02:00 PM roycroft: i do often make them a little oversize, though, as you described
02:01 PM roycroft: but i've also gotten good enough that i can cut them to final size and fit them flush
02:01 PM roycroft: so that saves a little material and the time spent sanding
02:01 PM JT-Shop: I made a modified version of William Ng's box joint sled
02:01 PM roycroft: i make mine on the router table
02:01 PM JT-Shop: main thing I did was make a pair of adjustment screws so I can dial in the width of the finger
02:01 PM roycroft: i have an icra jig, and a python script that generates the templates for me
02:02 PM roycroft: incra
02:02 PM JT-Shop: cool
02:04 PM roycroft: https://roycroft.us/Small-Drawer-Template.png
02:04 PM roycroft: the python script even generates templates for cauls
02:04 PM JT-Shop: sweet
02:05 PM roycroft: if you have an incra jig, the script is called pyrouterjig
02:07 PM roycroft: it can do variable spaced joints as well
02:08 PM roycroft: i like that when i'm making boxes - i can set it for equally spaced fingers, and then widen the one that i cut through to cut the top off by the width of the sawblade, and end up with evenly spaced fingers in the end
02:09 PM roycroft: it also does dovetails
02:09 PM roycroft: but i use my leigh jig for dovetails, if i'm not cutting them by hand
02:09 PM roycroft: http://lowrie.github.io/pyRouterJig/
02:10 PM roycroft: there's the direct link
02:10 PM roycroft: and lunch is finished, so it's time to break down the plywood and start making drawers
02:21 PM JT-Shop: this the one you have? https://www.incrementaltools.com/ProductDetails.asp?ProductCode=I-BOX
03:18 PM veegee_: I love it when thisoldtony gets chatter on his lathe
03:18 PM veegee_: makes me feel better about myself
03:18 PM veegee_ is now known as veegee
03:19 PM CloudEvil: https://www.youtube.com/watch?v=FlYKVpOVrcM Space shuttle sewing tecnology, with interview of one of the women doing it.
03:20 PM CloudEvil: (unfortunate occasional internet interruption
03:24 PM veegee: THe surface finish a shaper leaves with an HSS bit is great
03:24 PM veegee: I really want to understand why the surface finish on mild steel on a lathe with HSS is still not that great
03:25 PM veegee: totally fine on a mill
03:25 PM Tom_L: cutting angles
03:25 PM CloudEvil: Rigidity?
03:25 PM veegee: I have a rigid enough machine
03:25 PM veegee: But yes that's one factor. Larger workpieces almost always give me better finish
03:26 PM veegee: need to try with a follow rest and coolant. I think I'll use diesel fuel as coolant
03:27 PM veegee: water always makes me nervous near uncovered slideways
03:28 PM veegee: The vertical shear lathe tool definitely gives the best finish and tightest tolerance short of a toolpost grinder since it's doing almost what a shaper would do
03:30 PM veegee: Tom_L I've experimented with various cutting angles, even something like an extreme 60º top rake which looks like a knife
03:34 PM Tom_L: surface speed is lower than with carbide
03:41 PM veegee: Yeah I know
03:42 PM veegee: Way slower
03:42 PM veegee: For carbide on small parts, my lathe isn't fast enough. Only goes to 2,300 RPM. I need to modify it to boost the max RPM to at least 4,000
03:43 PM veegee: For HSS, I run it as slow as I can tolerate since the primary factor is heat on the cutting edge. Edge lasts forever at low RPM
03:43 PM veegee: I hone and examine the HSS tool after I grind it with a microscope to make sure the edge is good.
04:59 PM veegee: roycroft https://www.bison-america.com/produkt-27104-4605.html is this what I think it is!?
04:59 PM veegee: 4 jaw that can be coarse-adjusted like a 3 jaw self-centering, and then fine adjusted like a regular 4 jaw?
05:07 PM enleth: veegee: yes
05:08 PM veegee: excellent, exactly what I want
05:08 PM veegee: most annoying part is the coarse adjustment on the 4-jaw when changing workpieces
05:08 PM enleth: the SET-TRU chucks are nice, too
05:09 PM enleth: but more expensive
05:09 PM veegee: enleth yeah I was considering them, but that fine adjustment is only valid for that diameter
05:09 PM veegee: it's essentially a 3 jaw with wear compensation adjustment
05:09 PM enleth: there's a 6-jaw version
05:09 PM veegee: Which is fine, I'm sure it does exactly what it's designed to do, but super expensive
05:10 PM veegee: yeah I was going to ask, what is the purpose of the 6 jaw? Or anything with > 4 jaws?
05:10 PM enleth: repeats almost as well as a collet
05:10 PM enleth: and grips thin wall stuff better
05:10 PM veegee: Grip makes sense, but what makes it more repeatable?
05:10 PM veegee: Isn't the scroll mechanism the same?
05:11 PM enleth: I'm not sure about the internals
05:12 PM enleth: the user manual describes a specific tightening procedure to achieve repeatability
05:13 PM enleth: I mean, that's a lathe chuck with a user manual that you actually should read and keep
05:14 PM veegee: What's a "wedge bar" chuck?
05:16 PM enleth: veegee: there's a second tightening mechanism on top of the scroll
05:16 PM enleth: for very fast workpiece swapping
05:17 PM enleth: so you preset diameter with the scroll, but clamp and unclamp with the wedge mechanism
05:17 PM veegee: enleth ok thanks. And for the 6 jaw ones, you're referring to the set-tru models right?
05:17 PM enleth: yes
05:18 PM enleth: the regular 6-jaw is simply for delicate, thin-wall, etc workpieces
05:22 PM enleth: Abom79 has a 6-jaw set-tru, he's basically stopped using a 4-jaw for anything that fits this one ever sine he's got it
05:22 PM enleth: it does as good, or almost, as he can do on a 4-jaw, but faster
05:23 PM enleth: and he's fast with a 4-jaw
05:26 PM veegee: hmm might be worth the investment
05:26 PM veegee: enleth random question, but R8 and 5C collets have a keyway and notch. Safe to remove it? It's annoying and I never had an issue with the collet rotating while tightening
05:26 PM veegee: why do they even have that there?
05:36 PM enleth: I think this varies from machine to machine depending on spindle taper wear
05:36 PM veegee: In my vertical mill, I ground it off
05:36 PM veegee: zero issues
05:36 PM enleth: but I've seen plenty of people remove those notches
05:37 PM veegee: For my 5C collet holders, it's a set screw and I removed it, zero issues
05:37 PM veegee: Also lets me gently rotate the collet in the holder to make sure the fit is smooth
05:41 PM roycroft: i like the pin in the r8 spindle
05:42 PM roycroft: because one has to locate the pin every time one inserts tooling into the spindle
05:42 PM JT-Shop: this the one you have? https://www.incrementaltools.com/ProductDetails.asp?ProductCode=I-BOX
05:42 PM JT-Shop: ^^ roycroft
05:42 PM roycroft: which involves inserting a finger
05:42 PM roycroft: and making sure it's clean
05:42 PM veegee: I do that by habit
05:42 PM veegee: and blast it with purified compressed air
05:43 PM roycroft: if you do that by habit already then it's no hassle to locate the pin, because you've done so already
05:43 PM roycroft: no, jt-shop - i have the full jig
05:44 PM roycroft: https://www.incrementaltools.com/INCRA_LS_Super_System_25_Range_p/ls25wfncsys.htm
05:44 PM roycroft: i bought their original jig back in the '90s
05:44 PM JT-Shop: nice
05:44 PM roycroft: i sold that for more than i paid for it when i got the new one
05:44 PM roycroft: oh, it's so nice
05:44 PM roycroft: i just had to mill some slots in some plywood squares
05:45 PM JT-Shop: Estimated availability: Est. 20 – 24 week production lead time due to high demand
05:45 PM roycroft: i measured from one edge, and they needed to be centered 17/32" and 2-1/32" from the edge
05:45 PM Tom_L: you won't get it for xmas for sure
05:45 PM roycroft: i zeroed the fence to the center of the router cutter, moved the scale to zero, and set the jig to those dimensions
05:45 PM JT-Shop: you got that right
05:45 PM roycroft: jt-shop: you probably will get it before christmas
05:46 PM roycroft: taylor design group went to the montgomery scott school of estimating
05:46 PM roycroft: they tell you 20-24 weeks, and they usually deliver in 8-12 weeks, if not sooner
05:47 PM Tom_L: makes you feel better about them
05:47 PM roycroft: check other suppliers
05:48 PM roycroft: you can get incra stuff on amazon, grizzly, woodcraft, i think rockler
05:48 PM roycroft: and make sure you get what you really want
05:48 PM roycroft: you need a really big router table for that particular fence
05:48 PM roycroft: the 17" one will probably do most of what you ever need to do, if not everything you need to do
05:49 PM roycroft: and the wonderfence is nice for really tall items and for jointing on the router table, but it's not necessary for most things
05:49 PM roycroft: their standard system is fine for most purposes
05:49 PM roycroft: my old jig was 17", but i got the 25" when i upgrade
05:50 PM roycroft: i've considered buying a 17" positioner to save space - i've only had to use the full length of mine a couple times
05:50 PM roycroft: https://www.incrementaltools.com/INCRA_LS_Standard_System_17_Range_p/ls17sys.htm
05:51 PM roycroft: that one costs a lot less, and may well do everything you need
05:51 PM JT-Shop: https://www.woodpeck.com/woodpeckers-premium-router-package-prp-4.html
05:51 PM JT-Shop: that's my router table
05:52 PM roycroft: yeah, you won't be able to use the 25" incra on that
05:52 PM roycroft: unless you build an extension
05:52 PM roycroft: i built my router table, and use the incra router lift
05:52 PM roycroft: which is made by jessem
05:53 PM roycroft: i got an 80mm water-cooled spindle for it, and use that with a vfd
05:53 PM roycroft: and er20 collets
05:53 PM roycroft: and i use the wixey router dro for height adjustment
05:54 PM JT-Shop: I have the wixey on my planer, sure is nice to not guess
05:54 PM roycroft: yeah, i have it on my thickness planer too
05:55 PM roycroft: it's so nice
05:55 PM roycroft: i grab a piece of wood, measure how thick it is with some digital calipers, set the planer for that thickness less a smidge, and start running it through
05:55 PM roycroft: no testing/guessing the correct height for the first cut
05:55 PM JT-Shop: yup
05:55 PM roycroft: and no having to measure after every pass
05:56 PM roycroft: just dial it down to where you want, and there you are
05:56 PM roycroft: one of the best time-savers for the shop i've ever purchased
05:56 PM * JT-Shop reboots here to get qtpyvcp going
05:56 PM roycroft: i got a drill press dro as well from wixey
05:56 PM roycroft: and i'm going to get another planer dro to put on my drum sander
05:58 PM roycroft: jt-shop: i think the incra box joint jig is fixed width for the fingers, with micro-adjust
05:58 PM roycroft: you can't use templates like the one i linked to earlier
05:58 PM roycroft: no custom spacing
05:59 PM JT-Shop: the video shows adjustable width for the fingers
05:59 PM roycroft: oh
05:59 PM roycroft: i'll defer to it then
05:59 PM roycroft: i thought it was fixed
06:00 PM JT-Shop: which is the drawback of my built box joint jig you can only do one size finger
06:00 PM roycroft: it might be find then, if all you need is a box joint jig
06:00 PM roycroft: the ls positioner does a whole lot more
06:00 PM roycroft: like the job i did today - it's so easy with that
06:01 PM roycroft: as well, the slots i needed to make were for some 1/4"-20 bolts
06:01 PM roycroft: i used a 1/4" cutter, did the centered cut, then offset 0.010" to either side to widen it a wee bit
06:01 PM roycroft: trivial with the incra jig
06:02 PM JT-Shop: thanks for the info on it
06:02 PM roycroft: i've only ever cut dovetails with it to learn how that feature works - as i said, i use my leigh d4 for machine cut dovetails
06:02 PM * JT-Shop heads to the smoker to get it started
06:02 PM roycroft: and i don't make all that many box joints
06:02 PM Tom_L: what's for dinner?
06:02 PM roycroft: but i use that jig all the time for other things
06:03 PM * roycroft needs to head to market to get some food for dinner
06:03 PM JT-Shop: I'm always finding a work holding challenge in the wood shop
06:04 PM JT-Shop: see everyone tomorrow
06:04 PM roycroft: my cabinet is glued up and in clamps, the guide rail is epoxied onto my table saw sled, and i've fresh paint on the support for my disc sander
06:04 PM roycroft: so i've done what i can do for now - time to let glue and paint dry
06:04 PM roycroft: see yo
06:04 PM roycroft: u
06:04 PM roycroft: watch some youtube videos on the incra jigs
06:04 PM roycroft: there are quite a few of them, and some clever techniques
06:05 PM roycroft: i'm not too impressed with their wooden hinge jig, but if you're interested in wooden hinges, check out rob cosman's videos on how he makes them
06:05 PM roycroft: i really like his, and he sells the tools for them
06:56 PM XXCoder: interesting concept https://i.imgur.com/382WZ0z.gifv
06:58 PM XXCoder: its different way to do a arm
06:59 PM CloudEvil: 'Ah yes sir, certainly, that replacement gear will be $4000.'
06:59 PM CloudEvil: 'yes, it is the size of a grape'
07:00 PM XXCoder: it'd be assembled not made all at once
07:00 PM XXCoder: it'd be very expensive and hard if it was one solid ball
07:02 PM _unreal_: so got my new vacuum system up and did some tests
07:02 PM _unreal_: using a TEMP 15v psu
07:02 PM _unreal_: 24v one arrives tomorrow
07:02 PM _unreal_: even with the 15v one WOW does it move some air
07:02 PM CloudEvil: :)
07:03 PM XXCoder: from what i see, its slightly less flexable
07:03 PM XXCoder: but theres no singularies in it
07:03 PM _unreal_: XXCoder, any event horizons?
07:03 PM XXCoder: and easier to build i guess
07:06 PM XXCoder: ok i misremembered singularites
07:06 PM XXCoder: https://youtu.be/lD2HQcxeNoA
07:08 PM _unreal_: XXCoder, not to bad still has MICRO deviations but WOW still.
07:16 PM _unreal_: !!!!???? and the freaking power supply just stopped working
07:17 PM _unreal_: not even using it
07:17 PM _unreal_: wtf
07:18 PM Tom_L: does it need a load?
07:19 PM _unreal_: ! ok I am totally freaked out
07:19 PM XXCoder: seems not?
07:19 PM XXCoder: gif has part where it is just ball
07:19 PM _unreal_: the other end of the extentsion cored was not plugged in
07:19 PM _unreal_: at all
07:20 PM _unreal_: how the hell was the thing working?
07:20 PM XXCoder: trying to find more info
07:21 PM _unreal_: so its now plugged in??? and working
07:21 PM _unreal_: IT IS AMAZING how quiet it is. the old vacuum worked good but wow WAS IT LOUD
07:21 PM XXCoder: found it
07:21 PM XXCoder: https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9415699
07:21 PM * Tom_L wonders what _unreal_ is smoking
07:22 PM XXCoder: i stopped caring what unreal says for a while now
07:22 PM XXCoder: " If multiple degrees of freedom (DoF)can be actuated in a single joint, robots will become smaller, lesscostly, or more functional than conventional robots."
07:22 PM XXCoder: makes sense, though i can see that its slightly limited in certain directions
07:23 PM XXCoder: if whole assembly can rotate, then that problem goes away
07:26 PM XXCoder: intro is interesting. im not reading entire thing but jist looking at pictures for rest of it. though graphs is interesting too
07:26 PM _unreal_: Tom_L, same thing
07:26 PM Guest17: ???
07:27 PM XXCoder: hi
07:27 PM Guest17: All humans, raise your left hand
07:27 PM Guest17: :)
07:27 PM * XXCoder rises left hand with middle finger extended
07:27 PM XXCoder: ;)
07:27 PM Guest17: LOL
07:27 PM Guest17: we have a living one
07:28 PM XXCoder: anyway page 13 is definitely interesting
07:28 PM XXCoder: theres small amount of movemenrt errors
07:29 PM XXCoder: its also section where it discussion creation of ball gear
07:29 PM Guest17: <<< tommylight
07:29 PM Guest17: off to bed
07:29 PM Guest17: 2:16AM here
07:30 PM Guest17: have a good one
07:30 PM XXCoder: have good night
07:31 PM Tom_L: so he just joined to say hi?
07:31 PM XXCoder: seems so
07:31 PM Tom_L: ok
07:31 PM XXCoder: why not say hi? heh
07:31 PM XXCoder: anyway yeah its interesting read
07:57 PM _unreal_: so doing some milling jobs for work and I'm very happy
07:57 PM _unreal_: with the new vacuum system
08:02 PM _unreal_: hoping do wish it had a little more air flow
08:02 PM _unreal_: but the bigger psu may solve that
08:03 PM _unreal_: also the tubing on the upper section of the cyclone is a little smaller then I would like it to be
08:04 PM _unreal_: OH YA just pulled the hose off the blower
08:04 PM _unreal_: the upper section is clearly a handy capt
08:15 PM roycroft: aah
08:15 PM roycroft: i have all my drawer parts cut out
08:16 PM roycroft: i haven't had a proper general purpose table saw sled for a long time - i gave my old one away when i sold my old saw
08:16 PM roycroft: and while i've made a few special use ones for the new saw, i've never made a general purpose one
08:17 PM roycroft: things go so fast with a sled, and the cuts are dead square and perfectly sized
08:17 PM roycroft: and it's fast fast fast
08:27 PM JavaBean: and you have had a relapse... make sure you talk to your sponsor and councilor. they can help
08:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A12_New/A12_P1_chamfer1.jpg
08:29 PM Tom_L: so far so good
08:29 PM XXCoder: nice and clean
08:29 PM Tom_L: setup part
08:30 PM XXCoder: surpised didnt skim topm byt probably not needed since its not high precision part
08:30 PM Tom_L: i had the drills off as you can see on the side
08:30 PM Tom_L: i flipped it over and re'did it
08:30 PM Tom_L: no need, it gets tumbled anyway
08:31 PM XXCoder: ya was thinking more parallelism than texture :)
08:31 PM Tom_L: not a critical piece
08:31 PM XXCoder: yeah
08:32 PM Tom_L: i'll stick it back in and run the woodruff tool on it then to the bottom
08:32 PM Tom_L: don't have the cutter yet
08:33 PM Tom_L: the .093" on the base held good so far
08:34 PM XXCoder: thats good
08:48 PM _unreal_: so did a few small tests
08:48 PM _unreal_: granted I'm milling right now
08:49 PM _unreal_: but that blower is VERY VERY powerful for its tiny size
08:49 PM _unreal_: the upper cyclones on my two stage are too small
08:49 PM _unreal_: the tubes by design are under sized clearly
08:56 PM sparafuc1le: /names
08:58 PM Tom_L: joe, bob, billy, jane, sue
09:01 PM _unreal_: omg... I'm having a brain fart what the hell is it called when putting patterns of one type of wood into an other
09:01 PM _unreal_: like a compass rose
09:06 PM roycroft: the general term is inlay
09:06 PM Tom_L: inlay
09:06 PM roycroft: intarsia is a bas-relief form of inlay
09:07 PM roycroft: marquetry is a flat inlay form
09:12 PM _unreal_: INLAY
09:12 PM _unreal_: god!!!!
09:13 PM _unreal_: updating my ETSY account and I couldnt find that word no matter how I searched
09:14 PM roycroft: "inlay" is used more for strips of wood and the like
09:15 PM roycroft: the compass design that you mentioned is generally called "marquetry"
09:16 PM veegee: I was contemplating getting a dividing head, but I have a solid rotary table. I think I can just add a stepper motor to that and an encoder to correct for any backlash
09:17 PM CloudEvil: Or depending on how cheap you are, just always run it one way at the end.
09:17 PM _unreal_: arg... cut off cycle
09:17 PM _unreal_: heh
09:18 PM veegee: The thing is huge and I hate picking it up every time I have to put it on the mill table. Weighs over 40kg
09:18 PM _unreal_: I feel wastefull I have an un used 2x3" area on this label etching board
09:18 PM roycroft: dividing heads can generally be angled, which is difficult to do with a rotary table unless you have a really big sine plate
09:18 PM _unreal_: veegee, ouch
09:18 PM veegee: roycroft rotary table with a computer-controlled stepper motor?
09:19 PM Tom_L: veegee, i got a cheap chinese dividing head
09:19 PM Tom_L: fine for the times i will use it
09:19 PM veegee: an absolute position encoder can confirm the actual angle
09:19 PM veegee: Tom_L yeah I'm contemplating getting one
09:20 PM Tom_L: https://www.ebay.com/itm/112262120558?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
09:20 PM veegee: It also has locks which can be actuated by a cheap RC servo
09:20 PM veegee: It's the Vertex 10" model
09:21 PM roycroft: the rotary table doesn't get you the angle
09:21 PM roycroft: it just rotates
09:21 PM veegee: All Vertex tools I've bought surpassed expectations. Smooth out of the box
09:21 PM veegee: roycroft that's what the encoder and stepper motor are for
09:21 PM roycroft: but what if you need your rotation to be off axis?
09:21 PM roycroft: as in 30 degrees to the spindle, for example
09:22 PM veegee: What do you mean?
09:22 PM roycroft: with a rotary table you can hold your part parallel to the z axis or perpendicular to the z axis
09:23 PM roycroft: and spin it around
09:23 PM veegee: What does a dividing head do that a rotary table can't other than precise selection of angle
09:23 PM Tom_L: the base will angle as well as the rotational head
09:23 PM roycroft: yes, the base angles
09:23 PM roycroft: which is what i said earlier
09:23 PM veegee: Didn't know that, going to look into it
09:23 PM Tom_L: just repeating it for the veegee
09:23 PM roycroft: and why i mentioned needing a big sine plate to do that with a rotary table
09:23 PM veegee: Oh my bad, missed the message
09:24 PM veegee: So essentially a CNC dividing head haha
09:24 PM roycroft: i actually have need for that reature
09:24 PM roycroft: feature
09:25 PM roycroft: and i was looking into getting a sine plate big enough to hold my rotary table
09:25 PM roycroft: a dividing head is cheaper
09:25 PM roycroft: and i have divider wheels for my rotary table
09:25 PM roycroft: but i'm still going to get a dividing head so i can get the angle
09:26 PM veegee: what's BS-0/BS-1/BS-2
09:26 PM veegee: Tom_L damn, $130 shipping to Canada
09:28 PM veegee: ah angle can be set to cut helical gears I suppose
09:29 PM _unreal_: so the upper stage of the cyclone is CLEARLY working
09:29 PM _unreal_: I am thinking I need a taller bottle
09:30 PM _unreal_: or I need to add a deflector of some kind in the bottle I'm using to stop stuff from getting spun up
09:31 PM roycroft: awesome
09:31 PM roycroft: i just won some eyemuffs from a dave stanton raffle
09:33 PM JavaBean: eyemuffs?
09:33 PM roycroft: earmuffs with built-in safety glasses
09:33 PM roycroft: or safety glasses with built-in earmuffs
09:33 PM roycroft: however you want to look at it
09:34 PM JavaBean: interesting
09:34 PM roycroft: i've been wanting to check them out for a long time, but didn't want to spend $60 just to see if i like them
09:35 PM JavaBean: just remember, being "cheap" can get expensive
09:40 PM JavaBean: hmmm, it only hit 103f outside here today... they did say that tommorrow would be hotter tho
09:43 PM roycroft: "only" 28 here today, but we'll be well into the 30s by monday
09:43 PM XXCoder: 28f ;)
09:43 PM roycroft: i was going to stay home and work on projects during my vacation, but i may have to go to the coast if it really hits 37 like the forecast says
09:44 PM XXCoder: this week is going to be quite warm. 80f
09:53 PM _unreal_: I'm taking my daughter to the water park called the "rapids" tomorrow
09:53 PM _unreal_: in west palm beach
09:53 PM _unreal_: :)
09:53 PM _unreal_: weather depending
09:58 PM roycroft: that sounds like fun
09:58 PM XXCoder: here it averages 80 to 90f for summer
09:58 PM XXCoder: week or 2 of over 100f
09:59 PM roycroft: but we have relatively low humidity when it gets hot in the summer
09:59 PM XXCoder: it used to average less than a week but...
09:59 PM XXCoder: same
09:59 PM roycroft: in florida the humidity goes up with the temperature
10:01 PM XXCoder: thats more usual
10:19 PM _unreal_: and how
