12:00 AM Crom: pink_vampire: grizzlt, delta, HF 14" band saws have the upper cast iron arm, well, you raise it up usking "riser blocks" to move the upper wheel
12:03 AM roycroft: i don't, often, but i occasionally find really wide boards at some of the local sawyers
12:03 AM Wolf__: resaw, sounds like wood working
12:03 AM roycroft: yes
12:03 AM Crom: I need to seperate my wood and metal tools
12:03 AM roycroft: i can't really separate mine
12:03 AM pink_vampire: ok wood.. I'm talking about metal. and 18" round stock.... is life time supply for me
12:03 AM roycroft: but i dedicate them to either wood or metal
12:03 AM Crom: pink_vampire: stock the bandsaws can "resaw" 6" thick stock. a single 6" riser, adds 12" to blade length, and now you can make a 12" thick cut
12:03 AM roycroft: and i have covers for everything, so i don't get sawdust on my metalworking machines and metal shavings on my woodworking machines
12:03 AM roycroft: oddly, though, i've been thinking of upgrading my woodworking bandsaw
12:03 AM roycroft: and grizzly just came out with a bandsaw that is designed for both wood and metal
12:06 AM roycroft: i'm considering that
12:06 AM Crom: I cut AL on my HF band saw all the time
12:06 AM pink_vampire: Crom: do you have a picture / link of that?
12:06 AM roycroft: i made a small table for my 7x12
12:06 AM roycroft: but i really don't like freehand cutting on that saw
12:06 AM roycroft: it's a really bad compromise
12:06 AM roycroft: i'd prefer a proper vertical bandsaw for that, and i don't have the room nor the cash for both a wood and a metal vertical bandsaw
12:06 AM Crom: http://www.grizzly.com/products/Riser-Block-Kit-for-G0555/H3051?utm_campaign=zPage&utm_source=grizzly.com
12:06 AM Crom: https://www.youtube.com/watch?v=CvcNUS7kVo4
12:06 AM roycroft: http://www.grizzly.com/products/17-Metal-Wood-Bandsaw-w-Inverter-Motor/G0640X?utm_campaign=zPage&utm_source=grizzly.com
12:06 AM roycroft: that has a vfd
12:06 AM roycroft: which would make it pretty nice for wood and metal
12:06 AM pink_vampire: i'm watch it now
12:06 AM roycroft: it's somewhat tempting, but i don't like the idea of cleaning it out really well every time i want to switch materials
12:06 AM roycroft: sounds like a lot of maintenance
12:06 AM pink_vampire: sooo cool!!!!!!!!
12:11 AM roycroft: when i use the two riser blocks i have no blade guard for the left side
12:12 AM roycroft: and i have to use the guide arm for the single riser block with it, so my minimal height is 6"
12:12 AM roycroft: i can't bring the upper guides all the way down
12:13 AM roycroft: i had to buy a long 3/4" for it, but other than that i just stack the two blocks on top of each other and put the upper wheel on top of that
12:13 AM roycroft: long 3/4" bolt, that is
12:17 AM pink_vampire: i think it is a very good trick to get extra from your band saw.
12:17 AM pink_vampire: why you don't get the screw?
12:17 AM roycroft: with the two risers the blade can't be tensioned as much as ith a single riser
12:17 AM roycroft: the riser kit comes with a longer bolt
12:17 AM roycroft: but it is only long enough to bolt down one riser block
12:17 AM roycroft: two riser blocks is not a supported configuration
12:17 AM pink_vampire: what length do you need?
12:17 AM roycroft: i don't recall
12:17 AM roycroft: but i think 13" or 14"
12:17 AM roycroft: i'd have to go measure it
12:17 AM pink_vampire: just get a threaded rod
12:18 AM roycroft: i think i paid about $5 for the bolt
12:18 AM roycroft: 3/4" threaded rod would cost more than that
12:19 AM pink_vampire: https://www.lowes.com/pd/Hillman-0-75-in-x-36-in-Standard-SAE-Threaded-Rod/3128779
12:19 AM pink_vampire: $11.98
12:21 AM roycroft: and then you have to spend a couple bucks for a 3/4" nut to weld to one end of the threaded rod
12:21 AM roycroft: but threaded rod is an option if you can't source a long 34" bolt locally
12:21 AM roycroft: 3/4"
12:22 AM pink_vampire: why weld? just 2 nuts one on each end
12:24 AM pink_vampire: who can make me custom collet?
12:24 AM pink_vampire: do i need a machine shop for that?
12:28 AM Wolf__: collet for ?
12:28 AM pink_vampire: dewalt wp618
12:30 AM pink_vampire: Wolf__: ^
12:30 AM Wolf__: DW618 router?
12:30 AM pink_vampire: correct
12:31 AM Wolf__: 1/2 and 1/4 collets on ebay
12:31 AM pink_vampire: i want 1/8
12:33 AM Wolf__: what size do you have right now?
12:33 AM pink_vampire: 1/2 1/4
12:33 AM Crom: Which is why I went with a AC 3ph aircooled 1.5Kw spindle with VFD and ER16 collet chuck
12:34 AM pink_vampire: Crom: how much tir do you have on it?
12:34 AM Wolf__: http://a.co/ilSNK2y
12:34 AM pink_vampire: Dia. (Inner): 3.175mm(+/-0.1mm)
12:35 AM Crom: I can check Sunday or Monday, my 0.0001" indicator is at a freinds shop
12:35 AM Wolf__: yes
12:35 AM pink_vampire: thanks! i need better spindle
12:36 AM Wolf__: 3.175mm = 0.125” = 1/8
12:37 AM pink_vampire: i know but +- 0.1mm is alot
12:37 AM Wolf__: well, it is a spring collet sleeve
12:39 AM pink_vampire: i can't find what is the runout for it
12:41 AM Wolf__: http://a.co/4QxmxdX
12:41 AM Wolf__: might be better
12:42 AM pink_vampire: it look nicer!
12:48 AM roycroft: i'm using er20 for my router table spindle
12:49 AM roycroft: i don't like those collet reducers
12:49 AM roycroft: i have a 1/2" to 8mm one for hand-held routers
12:49 AM Crom: 0.08mm ish TIR
12:49 AM pink_vampire: roycroft: what router are you using?
12:49 AM roycroft: but then i found a proper 8mm collet for the thing
12:49 AM roycroft: i'm using a chinese 2.2kw 80mm water coole spindle, pink_vampire
12:49 AM Crom: but I did tighten the collet real tight
12:49 AM roycroft: for my new router table
12:50 AM roycroft: i have an incra mast-r-lift
12:50 AM roycroft: and the 80mm spindle fits it fine with a 0.015" shim around the spindle body
12:50 AM pink_vampire: 0.08 tir O_O that alot!
12:50 AM roycroft: the first spindle burned up a few days ago
12:51 AM roycroft: i have another one on order that is due to arrive on friday
12:51 AM jesseg: roycroft, roughly speaking, how many hours does it seem the first spindle ran for before burning up?
12:51 AM roycroft: i used a porter-cable 7518 router for my old rouer table
12:51 AM roycroft: roughly 10 minutes
12:52 AM roycroft: i'm convinced it was defective
12:52 AM jesseg: I guess it wasn't new
12:52 AM jesseg: oh it was new?
12:52 AM roycroft: yes, it was new
12:52 AM pink_vampire: i need something for 1/32" and 1/64"
12:52 AM Crom: tightened with wrench 0.075+mm TIR
12:52 AM roycroft: sadly, i did not test it for long enough when i bought it, so i could not return it as doa
12:52 AM jesseg: but anyway I meant to ask about how long your previous spindle ran before burning up
12:52 AM roycroft: but when the new one arrives, i'll test it for a long time
12:52 AM Crom: tightened with wrench 0.076-mm TIR
12:52 AM roycroft: and i bought a 4 year extended warranty on it
12:53 AM Crom: ER11 or ER16
12:53 AM pink_vampire: 1/64" is 0.4mm so 0.08 tir will kill it
12:53 AM IchGucksLive: morning from germany
12:53 AM jesseg: Good morning to Germany :D
12:53 AM IchGucksLive: pink_vampire: use a set of balscrews
12:53 AM roycroft: i used that porter-cable 7518 for about 20 years in three different router tables
12:53 AM jesseg: morning doesn't come here for another hour.
12:54 AM pink_vampire: IchGucksLive: we talk about spindle
12:54 AM roycroft: and when i decided to go with a spindle for the new one, i pulled the 7518 and put it back in its base
12:54 AM roycroft: so it's a hand-held router again
12:54 AM IchGucksLive: pink_vampire: yuo can get the 1605,2005 or even 2505 in about 2 inch values
12:54 AM IchGucksLive: oh the tool spindle
12:54 AM pink_vampire: i have ballscrew on my machine
12:54 AM roycroft: to answer your question more specifically
12:54 AM IchGucksLive: 2,2kw is best
12:55 AM pink_vampire: and 1000 rpm spindle
12:55 AM roycroft: folks on the various cnc router/engraver forums say those 80mm spindles last a couple to three years on average
12:55 AM IchGucksLive: but now the 3kw are getting up and cheeper even with er25 250USD
12:55 AM pink_vampire: and the china spindle is junk if you need 0.4mm end mill
12:55 AM Crom: hmm, I'll have to play with that 0.0029" is crappy
12:56 AM IchGucksLive: pink_vampire: in newburg is a mashine recicler that has old runouts like 500Maho thats woudt fit your needs
12:56 AM roycroft: i'd be fine with 0.001" tir on the spindle
12:56 AM roycroft: that's perfectly acceptable for a wood router
12:56 AM roycroft: 0.003" tir would probably be fine
12:57 AM pink_vampire: i know nsk make nice mini spindles but they cost 3
12:57 AM pink_vampire: 3K$ with the controller
12:57 AM roycroft: it all depends on what you need
12:58 AM pink_vampire: i want to make small parts faster
12:58 AM IchGucksLive: high speed about 60k rpm for a 0,4
12:58 AM Crom: I could bang it around a bit and get TIR lower
12:58 AM roycroft: i'll indicate my new one when i get it
12:59 AM pink_vampire: Crom: what do you mean?
12:59 AM IchGucksLive: im off school day
12:59 AM roycroft: https://www.amazon.com/gp/product/B011971H90/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
12:59 AM roycroft: that's the one i ordered
12:59 AM roycroft: maxes out at 24,000rpm
01:00 AM roycroft: so not good for tiny end mills
01:00 AM roycroft: fine for wood router bits
01:00 AM roycroft: my p-c 690 spins at 23,000rpm
01:00 AM pink_vampire: i know about them
01:00 AM roycroft: the 7518 has a variable speed motor, and the fastest speed is 24,000rpm
01:00 AM Crom: pink_vampire: look at the NYCCNC video's on lowering TIR, the collets don't always sit right... you can move them around a bit
01:01 AM roycroft: i hope the new spindle arrives on time
01:01 AM pink_vampire: if the nsk is 3K and that one is 300$ is there something in between?
01:01 AM roycroft: it left sacramento today, and there will be snow on siskiyou summit tomorrow morning
01:02 AM pink_vampire: like the mini spindles for swiss machines
01:03 AM roycroft: that spindle claims to have <0.005mm tir
01:03 AM pink_vampire: the new one?
01:03 AM roycroft: i guess i need to check right away, and get a replacement if it's more than that
01:04 AM roycroft: even though 0.05mm tir would be fine
01:04 AM Crom: oh, let me take out the collet, and check the taper
01:04 AM roycroft: i might as well get what they promise
01:05 AM pink_vampire: Crom: check the taper in several depths and clean it first!
01:05 AM roycroft: i wonder if that chinse guy with the vise on his floor does taper adjustments besides doing bearing replacements
01:05 AM roycroft: i'd like to see him do that
01:05 AM roycroft: study his technique
01:06 AM pink_vampire: probably nothing or just ID grinding
01:07 AM roycroft: pink_vampire: this is the guy i'm talking about:
01:07 AM roycroft: https://www.youtube.com/watch?v=4U1-6rEHBGA
01:07 AM roycroft: don't cringe too much
01:08 AM pink_vampire: WTFIT!!!
01:09 AM pink_vampire: omg!!! with the vise grip!!
01:10 AM pink_vampire: roycroft: !!!
01:11 AM roycroft: imagine him grinding the taper to true it up
01:12 AM pink_vampire: oh no!!!!!!!!
01:16 AM Crom: 0.005ish mm at all places on same axis line so not canted
01:18 AM pink_vampire: if the taper is 0.005, and with the collet is 0.08 your collet is dead
01:19 AM pink_vampire: test it with good collet and 4" drill rod
01:20 AM pink_vampire: test it cose to the collet and at the tip of the drill rod
01:21 AM pink_vampire: close*
02:05 AM gloops: https://www.ebay.co.uk/itm/Job-Lot-Of-79-Vintage-Engineers-Quality-Lathe-Milling-Reamers/382350919640?
02:06 AM gloops: tidy lathe by the looks https://www.ebay.co.uk/itm/Metal-Lathe-Gap-Bed-Vintage-New-240v-Single-Phase-Motor/273039943991?
02:07 AM Deejay: moin
02:07 AM archivist: there is one reamer amongst the taps!
02:07 AM gloops: lol, thought they were cheap
02:08 AM gloops: there is a nice box of reamers on ebay though
02:10 AM gloops: old brittania https://www.ebay.co.uk/itm/Colchester-Britannia-Lathe/222809589302?
02:10 AM gloops: the enthusiasts might end up with that - like C.F Booth
02:12 AM gloops: whats that machine on the end of it?
02:12 AM archivist: a bit unusual to still be treadle driven
02:12 AM archivist: engraving machine
02:13 AM archivist: http://www.archivist.info/cnc/works2008/P1010215.JPG
02:14 AM archivist: they copy and scale
02:15 AM gloops: hes selling that as well, no bids
02:16 AM pink_vampire: now days with the cnc i can't see any use for them
02:17 AM gloops: they are going for good money elsewhere
02:18 AM gloops: well there'll always be a bit of work for a manual lathe pink_vampire, that one is too old probably to be useful for much work anymore
02:18 AM gloops: or put it this way, there are better cheap old lathes if you just want a lathe at hand for little jobs
02:19 AM gloops: cnc pretty much eliminates manual engraving id think
02:20 AM pink_vampire: as long as you have olf fonts :)
02:21 AM pink_vampire: https://www.ebay.com/itm/HARDINGE-CONQUEST-ST-225B-SWISS-TYPE-AUTOMATIC-LATHE-SCREW-MACHINE-W-FANUC-18/292376096775?epid=11011625390&hash=item4412f93007:g:LsQAAOSwyP5aOJJD
02:22 AM archivist: gloops, there was a hand made thing on telly last night with hand engraving
02:22 AM pink_vampire: do you think it will fit in my apartment?
02:23 AM archivist: get a workshop for that
02:23 AM gloops: archivist people still carve wood with chisels and sit at a scroll saw, i doubt many furniture suppliers have a lot of people doing that now though
02:23 AM pink_vampire: archivist: i wish
02:24 AM gloops: 20k is an investment unless you have 20k for hobby toys
02:24 AM archivist: gloops, hand engraving http://www.collection.archivist.info/searchv13.php?searchstr=pd+norfolk+dial
02:24 AM gloops: you can invest in a lot of things with 20k - a truck, fine if you have contracts
02:25 AM gloops: it is no business plan though to buy a lathe with the hope of finding work for it
02:26 AM pink_vampire: gloops: i want small and fast spindle like the one on swiss machines
02:27 AM gloops: beautiful work archivist
02:27 AM pink_vampire: 2003!
02:27 AM pink_vampire: long time!
02:28 AM pink_vampire: beautiful art work
02:28 AM archivist: gloops, two of us worked on that, I did the infills and engraving, boss did pillars and silvering
02:29 AM archivist: the one on tv last night worked the same way, each skill was a different person
02:30 AM archivist: they mentioned that cnc engraving is too regular so did not look right
02:32 AM gloops: yes that is true with some things
02:33 AM pink_vampire: what is the name for it? http://cfnewsads.thomasnet.com/images/sites/4/2013/03/IBAGPIC1.jpg
02:33 AM gloops: same with wood carving, you can spot cnc a mile off - well if you know anything about it, the consumer usually doesnt
02:33 AM archivist: some kind of spindle
02:34 AM MarcelineVQ: at a glance it looks like a hydraulic spindle due tothe different port sizes, but it could be air as I don't know air well
02:35 AM gloops: air?
02:36 AM pink_vampire: i know it's a spindle, but i mean maybe it have more professional name / therm
02:38 AM archivist: spindle is the right name, with the addition of air/high speed etc
02:38 AM gloops: pneumatic drill spindle maybe
02:39 AM pink_vampire: it's the type of spindles that fo in the swiss machine
02:39 AM gloops: could be oil
02:40 AM gloops: its basically a die grinder
02:40 AM archivist: live tooling is the class of tools
02:41 AM archivist: http://www.ibag.ch/en/hscfit.html
02:42 AM gloops: air tools are generally too noisy for urban garages
02:42 AM archivist: http://www.ibag.ch/en/spindle-design.html
02:42 AM gloops: not just the amount of noise, the kind of noise, the pitch etc, ear piercing
02:43 AM pink_vampire: gloops: it's electric
02:43 AM gloops: thats ok then, i wondered about the fittings - looked like air or oil connections
02:43 AM MarcelineVQ: is it? guess the ports are for electric and coolant then
02:44 AM pink_vampire: air for the bearings
02:45 AM MarcelineVQ: fancy little thing :D
02:45 AM pink_vampire: nsk spindle+motor+controller = 3K$
02:45 AM gloops: you would need a compact but powerful spindle to have an array of them on a small machine
02:46 AM pink_vampire: they about 100-200W
02:46 AM archivist: make your own spindle using an RC motor
02:46 AM pink_vampire: no..
02:47 AM archivist: http://www.raynerd.co.uk/brushless-dc-motor-cnc-high-speed-spindle/
02:48 AM pink_vampire: archivist: "According the my hall effect sensor and Mach3 – I can get 10,100rpm max speed."
02:48 AM gloops: someone on diy-cnc made servos and spindles
02:48 AM gloops: doesnt talk much though
02:48 AM MarcelineVQ: outrunner's are pretty popular it seems
02:48 AM gloops: 100w wont cut much
02:48 AM gloops: its a dremel, a small dremel
02:49 AM pink_vampire: gloops: we talk about 1/8" end mill and smaller much much smaller
02:49 AM gloops: use similar for aluminium on routers, but much bigger spindles
02:52 AM pink_vampire: https://www.youtube.com/watch?v=-STJZ-UsiBY
02:56 AM gloops: someone i know works on a similar machine making similar things, they are pretty hi-tech machines lol, you thinking of making one of these pink_vampire?
02:57 AM pink_vampire: no, just want spindle like that,
02:58 AM gloops: i cant remember now, he showed me some photos a couple years ago, i know it has 2 chucks, like automatic chucks, and rotary tooling array, the operator basically does nothing
03:04 AM gloops: well no work on my machine today
03:05 AM pink_vampire: yeah, i wish i had one..
03:05 AM gloops: pink_vampire those machines are for high volume production of relatively low profit units
03:06 AM pink_vampire: with the right cam software and gcode is a dream machine
03:06 AM gloops: what application?
03:07 AM gloops: air hose connectors?
03:07 AM pink_vampire: tv replacement
03:07 AM gloops: my mate showed me what he made, he had 3 little widgets in his pocket, £2 items, they makes thousands
03:11 AM gloops: even i have failed to design and build an adequately rigid machine, i think, still some small movement when pressure applied to spindle
03:12 AM pink_vampire: for metal?
03:12 AM gloops: now only a matter of small plate deflection, and some slackness in the bearing blocks, hopefully can be adjusted out
03:12 AM gloops: no for wood mainly
03:12 AM gloops: it will cut ally
03:12 AM pink_vampire: i hate cutting wood
03:13 AM gloops: i reduced the x axis footprint at the last minute, to gain travel, that was a mistake, x bearings are taking the force now
03:13 AM pink_vampire: i need to find a way to make the anti static window for may mini sand blast box
03:14 AM pink_vampire: do you have any pic of the machine? it sound interesting
03:15 AM gloops: not very interesting lol, just a box section frame with cheapo chinese bits
03:15 AM pink_vampire: VERY interesting!!
03:15 AM gloops: it will cut fine but i wanted very very rigid, its probably just rigid
03:15 AM pink_vampire: I love stuff like that
03:16 AM gloops: https://ibb.co/cXfTib
03:16 AM gloops: not quite the jaegdpanther i set out to construct
03:17 AM pink_vampire: try to preload the rails
03:18 AM pink_vampire: it look super!
03:18 AM gloops: they can be adjusted - allen screw tightens bearing jacket, i have done much with that yet, only talking very little - and probably only at pressure that would snap a small tool anyway
03:18 AM gloops: havent done much
03:20 AM gloops: the accumulation is what catches people out, you force the plate - no not bending, well only a tiny tiny bit, add that to a tiny tiny bit of gantry flex, a tiny tiny bit of bearing slack - youve got a bit of deflection
03:21 AM pink_vampire: for very small bits make a small machine
03:22 AM pink_vampire: maybe add "X" to the frame
03:23 AM gloops: yeah originally the frames were to have more bracing, they are not moving though, i probably will add later
03:25 AM pink_vampire: https://i.imgur.com/k9X2Beu.jpg
03:25 AM pink_vampire: something like that will prevent flex in your machine
03:25 AM gloops: lol thats about a weeks work!
03:26 AM gloops: the frames arent bending, its mainly the plates and the bearings that are moving
03:26 AM pink_vampire: hooooooo
03:26 AM gloops: i will add some braces to the gantry anyway and do something with the x rails
03:26 AM pink_vampire: i see what you mean!!
03:27 AM pink_vampire: just add one more block ans connect it to the bridge with triangle
03:27 AM gloops: i will try it as is and analyse the results now
03:28 AM gloops: the frame is bolted down, very rigid, you can hit it with a hammer its solid
03:28 AM gloops: a hammer is shock loading of 20 tonnes
03:29 AM pink_vampire: as long as you preload the bridge it will get rigid
03:43 AM enleth: the bracing should be made out of steel rods with turnbuckles, right?
03:51 AM pink_vampire: any idea how to remove "loctite pl premium" from my hands?
03:51 AM gloops: well, up to about 2ft these box sections will not bend to any significant degree regardless
03:51 AM gloops: it mainly a matter of shortening the spans, i.e connecting them
03:52 AM pink_vampire: https://www.homedepot.com/p/Loctite-PL-Premium-10-fl-oz-Polyurethane-Construction-Adhesive-12-Pack-1390595/202056604?cm_mmc=Shopping|THD|google|D29B+Bath+Vanities&mid=s9JnGEXSz|dc_mtid_8903syd25186_pcrid_41293307497_pkw__pmt__product_202056604_slid_&gclid=EAIaIQobChMI9d7Psuvy2AIVhEZeCh2uFw_2EAQYAiABEgLwCPD_BwE
03:52 AM gloops: ive just found a password i really really need on an nearly full 500gb external drive from years ago haha
03:52 AM pink_vampire: i tried:water and soap, acetone, alcohol
03:53 AM enleth: pink_vampire: wait until the outer skin layers get replaced naturally and take the loctite with them
03:53 AM enleth: pink_vampire: 1-2 days at most
03:53 AM MarcelineVQ: I'd use an abrasive over acetone :X
03:53 AM pink_vampire: NOOO!!!!
03:53 AM enleth: pink_vampire: or liquid soap mixed with very fine sand
03:54 AM pink_vampire: my hands (and nails) look soooooo poor right now
03:58 AM enleth: pink_vampire: actually see if you have any skin care products that are supposed to be abrasive to remove dead skin cells and prevent acne, although they might not be enough
03:58 AM pink_vampire: but it will dry my skin
04:00 AM pink_vampire: https://www.youtube.com/watch?v=H2KHlHovDuw
04:00 AM pink_vampire: noooooo
04:00 AM enleth: skin lotion mixed with fine sand? doesn't really matter what you use as a carrier for the sand
04:00 AM pink_vampire: this guy is fucking insane!!
04:01 AM enleth: and I'm talking about sand fine enough that it's velvety to touch, not gritty
04:01 AM enleth: alternatively, you can get abrasive soaps that use celulose fibers instead of silica
04:01 AM enleth: or plastic beads
04:02 AM pink_vampire: i have silicon carbide lapping compound
04:17 AM XXCoder: hey pink_vampire been a while.
04:21 AM gloops: get some silicone eater
04:22 AM gloops: the sand thing - washing up liquid with sugar, or wash powder
04:22 AM pink_vampire: XXCoder: <3
04:22 AM gloops: or add sugar to white spirit
04:23 AM pink_vampire: I need to put my hand in ultrasonic cleaner
04:23 AM gloops: i got some of the wet application silicone on my old phone, it was still on it after 2 years
04:24 AM XXCoder: skin always grows so evenually glue will remove itself
04:24 AM XXCoder: unless its protein glue. silicone isnt protein glue so its fine
04:26 AM pink_vampire: it is PL loc
04:26 AM pink_vampire: it is PL glue
04:26 AM gloops: https://www.everbuild.co.uk/product/silicone-eater/
04:26 AM pink_vampire: https://www.homedepot.com/p/Loctite-PL-Premium-10-fl-oz-Polyurethane-Construction-Adhesive-12-Pack-1390595/202056604?cm_mmc=Shopping|THD|google|D29B+Bath+Vanities&mid=s9JnGEXSz|dc_mtid_8903syd25186_pcrid_41293307497_pkw__pmt__product_202056604_slid_&gclid=EAIaIQobChMI9d7Psuvy2AIVhEZeCh2uFw_2EAQYAiABEgLwCPD_BwE
04:28 AM XXCoder: not too bad then
04:28 AM pink_vampire: very bad
04:29 AM XXCoder: not as bad as protein glue would be
04:29 AM XXCoder: we are made from proteins :)
04:29 AM jthornton: morning
04:29 AM XXCoder: hey the chicken master
04:30 AM pink_vampire: what is protein glue??
04:30 AM XXCoder: its glue designed to glue meat together
04:30 AM XXCoder: if acciently glue fingers together with it, you need a doctor
04:32 AM XXCoder: anyway looks like what gloops said, some mineral spirits, pumice soap
04:36 AM XXCoder: lol watching soccer game, looks like one goal and 3 adults team against what looks like 10 times more kids
04:36 AM XXCoder: adults is going great but almost can't goal bec so many kids
04:40 AM XXCoder: cant find youtube of it drat
04:43 AM XXCoder: pink_vampire: been ,achining stuff?

12:06 PM IchGucksLive: hi
12:06 PM IchGucksLive: oh we got a new relese
12:06 PM IchGucksLive: whats UP
12:08 PM IchGucksLive: chinese
12:08 PM IchGucksLive: oh we might see cool lettters here dsoon
12:08 PM IchGucksLive: or derivats with onknown names
12:12 PM gloops: just watching on TV british steel scunthorpe just won a contract to sell 3000 tonnes of steel to china lol
12:12 PM gloops: thats like selling sand to the arabs!
12:13 PM gloops: steel for cranes, not sure if thats any kind of special steel
12:17 PM gregcnc: probably steel the chinese don't trust themselves producing
12:18 PM gloops: yeah could be, i seem to remember a big crane collapsing recently
12:18 PM gloops: 3000 tonnes is only chicken feed anyway
12:24 PM gregcnc: this would be fun to watch in action https://www.instagram.com/p/Bd6Ustzn3ps/
12:24 PM gloops: quite a few crane collapses in china on googling
12:25 PM gloops: cant see it
12:48 PM CaptHindsight: gregcnc: hmm seems a bit large for that size holder
12:50 PM CaptHindsight: gloops: that's part of the Chinese way, they are big gamblers

02:10 PM gloops: all quiet on the western front
02:13 PM jesseg: pretty quiet on this western front too
02:14 PM gloops: there is no western front on the north pole
02:15 PM gloops: which makes a polar sphere impossible to cnc

02:25 PM gloops: Not being used but taking up space so needs go.
02:25 PM gloops: All working
02:25 PM gloops: Please send offers by PM
02:25 PM gloops: Collection from M1
02:27 PM JT-Shopp: hmm this PC must need dusting it keeps resetting...
02:29 PM fragalot: /Me waves at gloops
02:29 PM fragalot: fail;
02:29 PM fragalot: :(
02:30 PM gloops: /Me waves back
02:47 PM CaptHindsight: finally found a good use for my 18 solid for stranded mistake..
02:47 PM CaptHindsight: sacrificial wire for electrolysis
02:52 PM fragalot: ha.
03:08 PM gloops: i wonder how a radio telescope is made
03:09 PM gloops: why cant a cnc be plotted by radar
03:10 PM fragalot: gloops: big receiver - and it can
03:10 PM gloops: i suspected as much
03:11 PM gloops: big receiver - large copper wire grid?
03:11 PM fragalot: depends on the type
03:12 PM fragalot: some are essentially satellite dishes, others are entire fields equipped with antennas
03:12 PM gloops: i bet you could pick up some stuff like utilising all your house rood or garden
03:12 PM gloops: roof
03:12 PM fragalot: you can, I think the first one was made in someone's back yard
03:17 PM gloops: yeah lots of diy examples
03:19 PM gloops: so, back to radar, a transmitter sends a radio signal, bounces and is received - cnc can encode its exact location, relative to markers maybe
03:20 PM fragalot: well radar is better for detecting moving objects than stationary ones
03:21 PM gloops: send the signal from the frame then
03:21 PM CaptHindsight: trying to make contact with the mothership?
03:21 PM fragalot: gloops: Sure, but why not use a less heavily regulated tech?
03:21 PM gloops: CaptHindsight we dont know whats out there, could some amateur enthusiast in his back room who finds out
03:22 PM gloops: fragalot heavily regulated, what radar?
03:22 PM fragalot: (all radar equiptment must be equipped with radar receivers & shut down if they detect an "official" signal)
03:22 PM CaptHindsight: someone in #electronics is doing similar with a 12ft dish
03:22 PM fragalot: assuming you have a transmitter
03:22 PM fragalot: receivers can of course stay online
03:22 PM gloops: ok what alternative could do the same thing - optical?
03:23 PM fragalot: optical would work fine
03:23 PM CaptHindsight: "attention earthlings, prepare to be invaded"
03:23 PM gloops: i reckon theres a few bob to be made in first contact
03:23 PM fragalot: optical systems already exist for part inspection, so I don't see why you couldn't make it work for live measurements & adjustments
03:23 PM gloops: these aliens are bearing gifts - i want to be in on it
03:23 PM CaptHindsight: "nevermind just monkeys"
03:24 PM gloops: fragalot i think it would be a good thing to incorporate into your design
03:25 PM gloops: laser measure on each axis with script to convert to axis co-ordinates
03:26 PM fragalot: pass.
03:26 PM fragalot: I'm happy with "basic" closed loop axis
03:26 PM fragalot: using encoders
03:26 PM fragalot: I like things to be predictable
03:27 PM gloops: would also serve as home and limits
03:27 PM fragalot: it shouldn't
03:27 PM fragalot: limits should be physical switches
03:27 PM fragalot: even if you crash into them hard, the contact HAS to break
03:27 PM fragalot: homing, you can do however you want :)
03:28 PM gloops: i bet something could be done with a scanner head
03:29 PM fragalot: it' more a question of "should you" rather than "can you"
03:29 PM gloops: im just thinking cnc could be a lot more
03:29 PM gloops: they need to move it on
03:30 PM fragalot: gloops: there are laser doppler systems that can do live in-place measurements
03:31 PM gloops: how about scanning a 3 object with laser?
03:32 PM CaptHindsight: I need a wearable sonar system with a few meter range and ~1cm resolution
03:32 PM fragalot: gloops: sure
03:32 PM gloops: how long before the amateur MRI system is here
03:32 PM fragalot: CaptHindsight: a few meters is stretching it for wearables I think
03:32 PM CaptHindsight: yeah, why I need it
03:33 PM CaptHindsight: 3-4 meters would be great
03:34 PM gloops: DIY X-ray CT scanner controlled by an Arduino https://www.youtube.com/watch?v=hF3V-GHiJ78
03:34 PM gloops: wow, i never think of anything new
03:34 PM Contract_Pilot: Maybe i will get to go play with mypindle today..
03:35 PM fragalot: CaptHindsight: I mean.. if you have $600 to spare
03:35 PM Contract_Pilot: My spindle
03:35 PM roycroft: put your pindle away
03:35 PM roycroft: this is a family channel!
03:36 PM fragalot: CaptHindsight: actually it seems that even the cheapo ones claim 4m distances https://robokits.co.in/sensors/ultrasonic-distance-measurement-sensor-4meter
03:36 PM CaptHindsight: gloops: + accelerometer for 3D ultrasound https://www.youtube.com/watch?v=0-92hatFap0
03:36 PM fragalot: CaptHindsight: so you can probably get about a meter out of them
03:36 PM Contract_Pilot: I think I have a plan of attack set the scale to 1.0 on the VFD and use the INI to adjust it.
03:37 PM fragalot: Contract_Pilot: do the manly thing and set both to 1 and just fool your CAM system instead :P
03:38 PM CaptHindsight: fragalot: this is for imaging
03:40 PM * fragalot hands CaptHindsight a box of bats and a clicker
03:40 PM fragalot: echolocate.
03:40 PM CaptHindsight: fragalot: bats with diving gear
03:41 PM fragalot: you'll have to provide your own - i'm not made of money
03:41 PM gloops: closed loop will not save you fragalot
03:42 PM gloops: we had someone in here showing a pretty big problem with closed loop steppers
03:43 PM fragalot: gloops: that's why you connect the steppers as open-loop & connect the encoder to linuxcnc
03:43 PM fragalot: gloops: all I care about is getting the rotational position of the leadscrew right
03:43 PM gloops: yes, i was just wondering if you understood that
03:44 PM gloops: how are you reducing the gearing?
03:44 PM fragalot: i'm not
03:44 PM gloops: not?
03:45 PM `Wolf: no need for gearing if you size the axis motors correctly
03:45 PM `Wolf: or over size them
03:45 PM fragalot: ^
03:45 PM gloops: i dont mean for torque, i mean for resolution
03:46 PM `Wolf: that probably comes down to drive pitch
03:46 PM fragalot: I currently have a resolution of 0.001mm / step which I personally think is fine
03:48 PM gloops: well 25 mm diameter shaft, say 80mm circumference, 200 divisions (steps) thats resolution of .4mm
03:49 PM gloops: not cutting resolution, the travel per step of your screw
03:49 PM fragalot: my bad, I meant 0.005mm
03:49 PM fragalot: 1000ppr encoder, 5mm pitch
03:49 PM fragalot: stepper is microstepping to 5000 pulses/rev
03:50 PM gloops: very good
03:52 PM gloops: fairly extreme microstepping though?
03:52 PM fragalot: none of the other choices on the driver come out to a sensible value
03:53 PM gloops: anyway 5000 steps gives 0.016mm rotation
03:53 PM gloops: per step
03:54 PM fragalot: how do you get to that number?
03:54 PM gloops: circumference of screw / 5000
03:55 PM fragalot: how is the rotational distance relevant?
03:55 PM gloops: well thats what the step is doing, rotating the screw
03:55 PM fragalot: yeah..
03:57 PM fragalot: so far i've only tried a single axis with a "flag" mounted on the output shaft of the motor, and repeatabillity seemed alright according to my dial test indicator
03:57 PM gloops: 0.001 on 5mm pitch screw
03:57 PM fragalot: yup, a nice round number I figured :)
03:57 PM Contract_Pilot: Need to go to HF and get a Pulley Puller...
04:01 PM gloops: sounds like its stuck Contract
04:01 PM Contract_Pilot: Not sure of i want to pull the spindle an stat stripping unnessarry gears to reduce noise.
04:01 PM Contract_Pilot: Start Stripping.
04:01 PM roycroft: there is no such thing as "stuck"
04:01 PM roycroft: there is always a bigger hammer
04:01 PM Contract_Pilot: Same mchine shat it looks like https://www.hobby-machinist.com/attachments/img_5257-jpg.73711/
04:02 PM fragalot: easy fix; weld a bar to it and ram it out with the lathe carriage's mass. :P
04:02 PM Contract_Pilot: Ahhh What
04:02 PM * fragalot is off to bed
04:02 PM Contract_Pilot: ONly need 1 Speed.
04:02 PM fragalot: bye all
04:02 PM gloops: abd break a casting
04:02 PM gloops: goodnight
04:02 PM fragalot: gloops: usually the casting sand and bondo cushion the blow
04:03 PM roycroft: breaking a casting makes for easier disassembly, and thus easier maintenance
04:03 PM gloops: something wedge shaped can get it moving, cold chisel behind it, keep moving it round to nudge it forward a bit equally
04:24 PM Deejay: gn8

05:24 PM gloops: £26 sawdust collector!
05:52 PM gloops: but probably overheats in about 5 minutes
06:00 PM gloops: wow, trump ended the war with a few tweets http://www.dailymail.co.uk/news/article-5309433/N-Korea-sends-rare-announcement-Koreans-calls-unification.html
06:04 PM MarcelineVQ: that's quite the simplification hehe
06:04 PM gloops: security by strength
06:04 PM MarcelineVQ: china isn't standing behind nk's anymore and they're out of other options since people are tired of listening to them rant anytime they want something
06:05 PM gloops: aggressive tweeting = peace
06:05 PM gloops: trump put china in its place thats why
06:05 PM gloops: 1 year year of trump and everything in the world is coming right
06:06 PM MarcelineVQ: that's a dubious statement but he has had meetings with them that went well
06:06 PM MarcelineVQ: I'm a fan of plenty of trump's decisions, though not all, but it's a little misleading to act like he's a singular factor hehe. I'm glad of the outcome though
06:08 PM gloops: yeah i agree, its time that korean standoff came to an end
06:09 PM MarcelineVQ: sucks for south korea though, a whole country of backwards economic refugees is about to swarm them.
06:10 PM MarcelineVQ: at least there wont be a government directly threatening to kill them every other sunday
06:10 PM gloops: i doubt a revolution is possible in NK, with the level of brainwashing
06:10 PM gloops: so exodus is likely if the opportunity arises yes
06:16 PM gloops: i guess seeing the usa navy and air force at close quarters helped, NK does have 20 or so mig 29s but doubtful many pilots or techncians
06:51 PM gloops: The Canadian and British Foreign Office have now issued official travel warning to Swedish city Malmö.
06:51 PM gloops: wow, just wow, Sweden

06:53 PM Tom_L: pretty cool hs photography i thought
06:55 PM gloops: there was one of those cutters going cheap on ebay here, i have no use for it, dont think it went for that much
06:55 PM MarcelineVQ: lighting for slow-mo is difficult
07:00 PM gloops: i was going to look at designing a cncable large format wood film camera, when i finally get a working router
07:01 PM gloops: it seems pretty doable, even the bellows could be scored with a dragknife, theyre quite expensive to buy
07:05 PM gloops: https://i.pinimg.com/736x/4c/d8/6d/4cd86d9a6df2c7a1f495cd36e0d79692.jpg
07:17 PM Tom_L: can you still get film?
07:17 PM Tom_L: i bet it's hella expensive if you can
07:18 PM gloops: black and white is still readily available, its making a bit of a comeback, colour - still avialable but question mark over how long
07:19 PM gloops: most film for small cameras was surplus from cinema film - thats almost gone, the truly good films have gone now
07:21 PM gloops: film was actually superior to digital in terms of resolution and tonal range...until around a year ago, the new sensors match/beat film
07:21 PM Tom_L: yeah
07:22 PM Tom_L: took skill to do it all 'in camera' back then
07:22 PM Tom_L: i've got all sorts of digital editing tools
07:23 PM gloops: thats what the revival is mainly about - its an art or skill etc, not just clicking and the camera does everything
07:24 PM gloops: BW will probably go on, its easy to make and theres a market for it still
07:27 PM gloops: some money on photography Tom, if youre good enough
07:27 PM gloops: in
07:27 PM Tom_L: not that much
07:27 PM Tom_L: the market has changed for sure
07:28 PM gloops: weddings about £1500 a shot, not a bad way to make a good living, couple of wedding shoots a week
07:28 PM Tom_L: years ago a bud and I used to go shoot pics and he turned it into a business
07:28 PM gloops: did he go anywhere with it?
07:28 PM Tom_L: for quite a few years yeah
07:28 PM Tom_L: he's since sold the business
07:29 PM Tom_L: the mrs has been helping a friend that worked for him for years that got the business from him
07:29 PM gloops: im was pretty interested in it, got boxes of old cameras, not had time for a while
07:30 PM Tom_L: doint all the editing
07:30 PM Tom_L: g
07:31 PM gloops: i suppose the big drawback is that the better digital cameras get and the easier to use - more people try to make money from it
07:31 PM Tom_L: she's been kinda lax getting the business going again
07:31 PM gloops: millions of pics posted on flickr and instagram
07:31 PM Tom_L: yeah but they still need tools to make them look 'professional'
07:31 PM gloops: true, you dont get anywhere with photos straight from the camera
07:32 PM gloops: there is still a lot of skill and knowledge required to be good
07:32 PM Tom_L: so i got her photoshop, lightroom, topaz and a few other things
07:33 PM gloops: a lot seem to use lightroom now, especially for landscape photos
07:33 PM Tom_L: i suppose it could be a success if the gal would get off her arse and make it work
07:33 PM Tom_L: it's better than photoshop for alot of things
07:34 PM Tom_L: topaz is another good tool
07:34 PM Tom_L: and i got her a buttload of presets to make it easier
07:35 PM gloops: there was a bloke on a photography channel on here, i was in there when he first started, he made some money from it, doing massive panoramas, 100s of shots combined, was incredible detail - he printed them out himself like 8x3ft prints
07:35 PM Tom_L: heh
07:36 PM gloops: he just kept buying really expensive gear, top lenses and printer, everyone was saying - this aint gonna work - but it did pay off
07:40 PM Tom_L: i gotta get my Z axis trued up but i'm just too tired to go out there tonight
07:40 PM Tom_L: figure out some way covers and maybe i can start using it
07:42 PM gloops: well ive got some time tommorrow, maybe get to the point where i can start connecting it up to a computer, i reckon theres gonna be a good while snagging up yet though
07:43 PM Tom_L: i still gotta mount the spindle to the machine too
07:43 PM Tom_L: it's on with clamps right now but i got it somewhat squared up with the column
07:43 PM Tom_L: so i can finish drilling the mounting holes
07:43 PM gloops: lol, you think youre finished but there always seems to be just this and that left
07:44 PM Tom_L: i put a short tool in and made sure i had reach and hopefully i won't lose too much travel doing so
07:46 PM gloops: ive been looking at that, clearance and where the spindle bracket should be, tbh ive lost a bit of interest at this stage and not spending much time thinking things through, probably end up changing it later when the plate bumps the job

08:17 PM jesseg: Cool to see 7 segment LEDs making a comeback or at least not dying off and being replaced by LCD. These would make a nice DIY DRO! https://www.ebay.com/itm/MAX7219-8-Digit-LED-Display-7-Segment-Digital-Tube-For-Arduino-Raspberry-Pi/112213251047
08:19 PM Contract_Pilot: have the 8TB drive in the USB on the GT-5300 and well keep getting you need permission WFT i have it set for annom.
