01:18 AM Deejay: moin
04:54 AM jthornton: morning
04:55 AM jthornton: Are you the owner? What is the present condition and the firm price?
04:55 AM XXCoder: ?

05:00 AM Tom_L: morning
05:00 AM jthornton: yo
05:00 AM XXCoder: hy
10:30 AM jymmmm: Good morning folks
11:13 AM Deejay: good evening, jymmmm :)
11:13 AM jymmmm: hey Deejay =)
12:34 PM Connor: Opinions on a genuine Phase I piston style Quick change tool post vs a Bostar/Accuszie Wedge one? I've always liked the wedge better myself..
12:35 PM dirty_d: So my electrical enclosure and motor cable shields should be connected to AC ground, and DC grounds should be isolated from everything?
12:35 PM dirty_d: DC ground*
12:37 PM dirty_d: My motor encoder datasheet says to connect it's ground pin to the motor chassis though, and that would tie DC ground to AC ground
02:06 PM CaptHindsight: look at those angle plates! https://springfieldil.craigslist.org/tls/d/modesto-horizontal-boring-mill-fixture/7041070861.html
02:07 PM CaptHindsight: 3 tons ea, 36”x48” 96” tall
02:13 PM Jymmm: CaptHindsight: They have holes in them... forget it
02:29 PM roycroft: crappy angle plates
02:29 PM roycroft: they're just machined, not scraped
02:29 PM roycroft: if you buy them you have to spend 17.4 years scraping them before they're useful
02:30 PM Jymmm: roycroft: That's TOTAL bullshit....
02:30 PM Jymmm: roycroft: more like 45 years
02:31 PM roycroft: i'm assuing you have a biax scraper
02:44 PM veegee: If I'm recording welding using my expensive mirrorless camera, should I get UV protection filters for it?
02:45 PM veegee: I'm going to put it behind a glass shield anyway to prevent something from damaging it, but will a UV filter get better video results? Or prevent possible damage to the sensor?
02:48 PM roycroft: i won't be held responsible for what i'm about to say, but complete idiots video welding stuff and put it up on youtube all the time, and complete idiots tend to be folks who like to whine and complain and blame others for their own stupidity, and i've not seen any of them whine that they destroyed their camera recording the welding stuff
02:49 PM roycroft: which leads me to believe that cameras generally are ok recording welding operations without special filters
02:50 PM * roycroft notes that if filters are required to avoid damaging a camera, and if said youtubers were aware of this and acdtually installed the proper filter, they could no longer be categorized as "complete" idiots
02:53 PM Jymmm: veegee: You mean a DSLR camera?
02:53 PM veegee: Same idea yeah
02:53 PM veegee: Technically mirrorless, so not "SLR". It's a Sony A7R III
02:54 PM veegee: But UV filters are cheap enough anyway, so I'll add one
02:54 PM Jymmm: veegee: It's not a bad idea to put a UV filter on your lenses anyway, A filter is cheaper than replacing the lenses in case of being scratched.
02:54 PM veegee: It's a $4,000 camera and $3,000 lens
02:54 PM veegee: I use a clear glass filter instead of a UV filter
02:55 PM Jymmm: Ok, same thing.
02:55 PM veegee: But for welding, I'm thinking about UV specifically since it produces a lot of UV light
02:55 PM Jymmm: and if recording welding, a polycarb shield should provide physical protection
02:56 PM Jymmm: Then grab a UV filter for you lenses
02:57 PM roycroft: i'd agree to using a protective filter for physical protection
02:57 PM roycroft: a uv filter won't filter nearly all the uv that a welder emits
02:57 PM roycroft: unless it's one of the really dark ones designed for taking pictures of the sun and the like
02:57 PM Loetmichel: veegee: be careful if you are close
02:57 PM Loetmichel: the energy of the arc CAN actually be enough to damage the CCD chip
02:58 PM Loetmichel: if close enough
02:58 PM roycroft: for a camera that expensive i would ask the camera manufacturer, not folks on irc
02:58 PM Loetmichel: i would recommend to put a welding glas in front of the UV filter
02:58 PM Loetmichel: or clear glass filter
02:58 PM Loetmichel: so you attentuate the "flame"
02:59 PM veegee: Good point regarding intensity
02:59 PM Spida: why use such an expensive camera and not some action cam?
02:59 PM veegee: I'll put a neutral density filter on it too
03:00 PM veegee: It's just the camera I use all the time for everything. I don't have a specific action cam
03:00 PM Spida: why risk it?
03:00 PM veegee: I have a shitty iPhone 11 p ro
03:00 PM veegee: but cell phone cameras are garbage compared to a real camera
03:01 PM veegee: the image/video quality difference between an action cam and this thing is significant
03:01 PM Loetmichel: depends
03:01 PM Spida: there are a number of youtube channels about welding, maybe contact these guys
03:01 PM veegee: but yeah I should ask Sony
03:01 PM Loetmichel: if you damage the sensor the DSLR is the garbage afterwards ;)
03:01 PM veegee: neutral density filter should be able to attenuate it.
03:02 PM Spida: i have a dslr, too, but I do NOT believe that the image quality IN THIS SITUATION will matter that much
03:04 PM dirty_d: If you're filming actual welding wouldn't you just film it through a welding mask filter so it's the right brightness?
03:06 PM Spida: what kind of image quality does your camera provide that you need for welding? color correctness? fast autofocus? low-light performance?
03:28 PM Elmo40: high speed?
03:36 PM Jymmm: Personally, I wouldn't have a $7000 camera even in the same room as a welder
03:40 PM SpeedEvil: Welding is not that bright
03:40 PM SpeedEvil: you're limited to only several times the surface brightness of the sun.
03:41 PM SpeedEvil: a neutral density filter, and it works well
03:41 PM SpeedEvil: LASERs are another matter.
03:46 PM Jymmm: SpeedEvil: Yeah, a 1/8 sheet of polycarb for up to 100W CO2 works for lasers =)
03:47 PM SpeedEvil: Visible LASERs
03:47 PM SpeedEvil: Everything in a 'normal' camera completely blocks CO2
03:48 PM Deejay: gn8
03:48 PM Jymmm: devlap: gn9
03:49 PM Jymmm: SpeedEvil: screw camera, I'm talking my eyesight =)
03:49 PM SpeedEvil: Ah
03:49 PM SpeedEvil: Pretty muc the same answer really
03:49 PM Deejay: jymmmm, you did wrong! ;)
03:50 PM Jymmm: Deejay: I blame this devlap person
03:50 PM SpeedEvil: Your cornea 100% absorbs CO2, and your eye is only slightly more damaged than skin by CO2 LASERs.
03:50 PM SpeedEvil: That said - burns on your eye even if the same severity are obviously lots worse.
03:51 PM SpeedEvil: But - it doesn't have any optical gain at all, like visible LASERs do whenthey go through the lens
03:51 PM Jymmm: SpeedEvil: Well, I might go blind if I play with myself, but at least I'm safe when I play with my laser =)
03:52 PM Jymmm: SpeedEvil: And I only defeat the interlocks when I have to calibrate the laser, so not a big big deal
03:59 PM SpeedEvil: Technically, you can use an occulus quest as a infinite LASER safe thing.
04:00 PM Jymmm: lol
04:01 PM Jymmm: SpeedEvil: "The Oculus Quest is a virtual reality headset created by Oculus VR, ---> a division of Facebook Inc. <---"
04:01 PM SpeedEvil: yes
04:01 PM SpeedEvil: It's got external cameras which you can sort of use.
04:01 PM SpeedEvil: It would be nice if it was better.
04:02 PM Jymmm: Or, just a pair of glasses works too
04:02 PM SpeedEvil: yeah - if you happen to have picked the correct waveband.
04:03 PM roycroft: so when you buy an oculus, facebook can see everything that you see in the thing
04:36 PM gloops: hmm, i found a couple of 4 inch stubs of sbr rail in a box, got a couple of bearings, my pen holder is gonna be the works
04:41 PM SpeedEvil: :)
04:43 PM gloops: probably ought to look on ebay first though, theyre probably about $3 lol
04:43 PM gloops: https://www.youtube.com/watch?v=WddzboHHkGw
04:45 PM gloops: https://www.ebay.co.uk/itm/12mm-Cutting-Plotter-Pen-Holder-Seat-Cutter-Pen-Vinyl-Holder-Part-Tool-Universal/273515175512?
04:45 PM gloops: i wasnt far out
04:45 PM gloops: and that is pretty shocking finish
05:51 PM _unreal_: ve7it, hello. just got parts for my daughters cnc machine and mine :)
05:52 PM _unreal_: after I shower I'm going to start wiring like a MOFO
05:52 PM _unreal_: heh
05:52 PM _unreal_: I have but to drill a HOLE and start running wires to an adapter. and wires to the other adapter
05:52 PM SpeedEvil: https://www.youtube.com/watch?v=cLSIRflKtEo - on 'shocking finish
05:53 PM _unreal_: SpeedEvil, what kind of a finish?
05:54 PM gloops: looks like they were tested on concrete
05:54 PM SpeedEvil: Indeed
05:56 PM gloops: i had a thought of getting a plotter to leave gold leaf size on a pattern or text, dont see how it can be done though
05:56 PM gloops: at least it can draw it, to be painted in by hand
05:57 PM _unreal_: got my threaded rods today as well
05:57 PM _unreal_: got them turned down
05:57 PM _unreal_: now I just need to mill retainer starboard blocks
05:58 PM SpeedEvil: https://www.cooksongold.com/Wire/Q9999-Fine-Gold-Wire-0.50mm-Fully--Annealed-Reels-prcode-HRY-050&add=n Or just inlay. Only $300 or so for 1m of 0.5mm wire.
05:58 PM _unreal_: and I can mount them
05:58 PM gloops: or maybe if you could stick vinyl over the piece and get a blade to slice out the pattern - could paint straight on then
05:59 PM gloops: vinyl for masking
05:59 PM SpeedEvil: Actual gold leaf is pretty cheap.
05:59 PM SpeedEvil: Hmm
06:00 PM gloops: yeah it is, time consuming painting the size for a lot of text or pinstriping though
06:00 PM gloops: if you could just get the cnc to lay the size precisely
06:01 PM SpeedEvil: I guess even your standard 3dp might manage that
06:02 PM gloops: put a print head on the router?
06:45 PM XXCoder: hey JT-Shop
07:06 PM Rab: <_unreal_> hay Rab remember that "fake welder" ebay thing?
07:06 PM Rab: _unreal_, I sure do.
07:08 PM andypugh: When gloops gets back, tell him to google “refillable plotter pens”
07:42 PM SpeedEvil: Rab: did you get anything?>
07:43 PM Rab: SpeedEvil, I got exactly what I ordered.
07:44 PM Rab: So no.
08:57 PM Rab: What devilry is this. https://smile.amazon.com/dp/B07GB55727
08:58 PM XXCoder: very safe
08:58 PM Rab: Furiously adding to cart, throwing out all other tools I own.
08:58 PM XXCoder: man, drill motor, drill chuck, timing belts, bracket, and rod block
08:58 PM XXCoder: 0% of that is new
09:44 PM SpeedEvil: https://www.aliexpress.com/item/33028960092.html
09:44 PM SpeedEvil: If you want safe.
09:45 PM SpeedEvil: (this is not it)
09:45 PM SpeedEvil: - I got one of these - but I do not plan on using it with an angle grinder, but a brushless motor, with gyro ebrake
09:45 PM SpeedEvil: And overcurrent ebrake
09:45 PM SpeedEvil: - as a backup
09:46 PM XXCoder: wttttf
09:46 PM XXCoder: you see really bad photoshop there?
09:47 PM SpeedEvil: No
09:47 PM XXCoder: watch out some giant cutting huge log
09:47 PM XXCoder: https://ae01.alicdn.com/kf/HTB1Vq.7aW5s3KVjSZFNq6AD3FXaY.jpg
09:47 PM SpeedEvil: What do you mean?
09:47 PM XXCoder: wrong pic a sec
09:47 PM SpeedEvil: Oh - yes - of course it's a 12" bar.
09:48 PM XXCoder: https://ae01.alicdn.com/kf/HTB1Rs3Ya2WG3KVjSZPcq6zkbXXaM.jpg?width=800&height=630&hash=1430
09:48 PM XXCoder: guys HAND is bigger than tree tranks
09:48 PM SpeedEvil: https://smile.amazon.co.uk/BLACK-DECKER-36-Lithium-Ion-Chainsaw/dp/B00QTV3QWS
09:48 PM SpeedEvil: Oh - yeah - that's a terrible photoshop
09:49 PM SpeedEvil: I kinda automatically ignore everything that isn't obviously not a photoshop
09:51 PM XXCoder: lol ok
09:51 PM XXCoder: me, i enjoy bad ps
09:51 PM XXCoder: you ever seen one of those finger beltsander?
09:51 PM XXCoder: pretty awesome
09:52 PM SpeedEvil: yes, I have one.
09:52 PM XXCoder: was it useful?
09:52 PM SpeedEvil: I am almost considering replacing the motor with a brushless one.
09:52 PM SpeedEvil: Because it's so fucking loud with the existing one.
09:53 PM XXCoder: i have mini belt sander pretty cool. (not finger type)
09:53 PM SpeedEvil: https://smile.amazon.co.uk/gp/product/B000XSP72K
09:54 PM SpeedEvil: Last used it to finish off the edge of my letterbox after widening it.
09:54 PM SpeedEvil: Really handy for 'just a little bit wider'
10:04 PM Rab: <XXCoder> guys HAND is bigger than tree tranks
10:04 PM XXCoder: lol
10:04 PM Rab: Scaled to the bar, it's about the size of a 5yo's hand.
10:05 PM Rab: But hairier than a 5yo's.
10:05 PM XXCoder: yet compare it to wood and trees
10:05 PM XXCoder: hairy child giant
10:05 PM Rab: From the bottom of the barrel of gweilo hand clip art.
