01:47 AM Deejay: moin
05:12 AM JT-Cave: morning
05:13 AM XXCoder: yo
06:34 AM Tom_L: morning
06:34 AM XXCoder: yo
06:58 AM JT-Cave: https://youtu.be/NiFe19efem8
07:09 AM Tom_L: nice
07:32 AM JT-Cave: ordered the smart stepper drive and a HMI yesterday
07:43 AM JT-Cave: I just love it when examples don't work at all or are missing some crucial bit of information
09:18 AM beachbumpete1: Good Morning
09:29 AM JT-Cave: oh my my planer parts are out for delivery!
11:20 AM holzjunkie1 is now known as holzjunkie
11:24 AM holzjunkie1 is now known as holzjunkie
12:15 PM jymmmm: late morning ;)
12:23 PM _unreal_: YEP I love it I got my new z setup
12:23 PM _unreal_: late mornning how baout after noon?
12:24 PM _unreal_: just finished cutting the first 2 parts for my new z nut for the new cnc machine
12:24 PM _unreal_: I was going to go with one setup but I have no chan ged my mind and I'm going to go with the new setup. it has built in limit switches LOVE IT
12:25 PM _unreal_: and I can directly mount it with an adapter mounting plate to my Z lead screw hardware
12:25 PM _unreal_: going to be amazing
12:25 PM _unreal_: it is a tiny bit tighter then I would like it to be but the parts fit
12:25 PM _unreal_: so they will wear in :)
12:25 PM _unreal_: and maybe a little lube will help :)
12:36 PM roycroft: ups just arrived, and i was not impressed
12:37 PM roycroft: i ordered some wall calendars from barnes & noble, since going to the mall was right out this year
12:37 PM roycroft: i ordered five of them, and i got five separate shipping notices
12:37 PM roycroft: two of the five arrived today
12:37 PM roycroft: each in its own ginormous box
12:38 PM roycroft: i'm talking a box that's 5 feet long by 3 feet wide by a foot thick
12:38 PM roycroft: for one calendar and more bubble wrap that anyone can stress relieve pop in a year
12:38 PM roycroft: i bought all the calendars on boxing day, so they were half price
12:39 PM roycroft: i figure that for a $7.95 calendar they spent at least $12 on packaging and shipping
12:56 PM _unreal_: sweet slavaging one of my milled parts
12:56 PM _unreal_: it was slightly over sized but re-did offsets remounted the single finished part and retooling the out of sized part
12:57 PM _unreal_: heh
01:07 PM _unreal_: hum
01:08 PM _unreal_: I'm toying with trying to do HDPE welding :S if I can weld on a small bit of HDPE to the 4/final part I already milled I could just do the adjustment and relief
01:08 PM _unreal_: AND 3d milling job on it
01:08 PM _unreal_: ohhhh
01:08 PM _unreal_: would be nice
01:42 PM gloops: like they make window frames, melt each face and press together
01:43 PM _unreal_: used my hot air station
01:43 PM _unreal_: with luck its melted good
01:43 PM _unreal_: preping the cad drawing right now to do the custom mill job
01:50 PM _unreal_: ok first milling job
01:51 PM _unreal_: err first of the final part
01:51 PM _unreal_: got 4 stages
01:51 PM _unreal_: 3 stages
01:51 PM _unreal_: adjusted profile job
01:51 PM _unreal_: then the 3d job
02:09 PM Tom_L: _unreal_, what was the threadmill for?
02:09 PM Tom_L: you try it yet?
02:10 PM _unreal_: try no
02:10 PM _unreal_: for a project I have not yet started
02:27 PM _unreal_: Tom_L, the threadmill is for the new cnc machine when I get the Z and everything working so it can thread its own damn screw down table
02:30 PM _unreal_: well that sucked
02:31 PM _unreal_: estl cam failed me for once when it comes to 3d :(
02:31 PM _unreal_: milling
02:31 PM _unreal_: it litteraly didnt even read the damn file
02:31 PM _unreal_: FACK
02:31 PM _unreal_: now I have to melt more plastic into the one side I worked on
02:31 PM _unreal_: :(
02:31 PM _unreal_: it just did straight plunge cutting
02:31 PM _unreal_: zero 3d
02:32 PM _unreal_: well time to boot up fusion
02:38 PM _unreal_: no one live today
02:42 PM _unreal_: and fusion has locked me out with updates
02:42 PM _unreal_: ARG
03:08 PM _unreal_: finally fusion finished fucking around and updating
03:15 PM _unreal_: ARG... and they have changed everything again inf usion
03:15 PM _unreal_: fuck me
03:15 PM _unreal_: got to re-learn how to do the simple task I was going to do again
03:15 PM _unreal_: FACK
04:45 PM XXCoder: JT-Cave: check this out https://youtu.be/IQUnEU4hdOU
04:45 PM XXCoder: its linear plasma cutter
04:45 PM XXCoder: automated so its less of a hassle
05:18 PM JT-Cave: I now know 2 people that have died from covid, neighbor around the corner spent 18 days in the hospital before dying
05:18 PM XXCoder: :( that sucks
05:18 PM JT-Cave: yea
05:19 PM JT-Cave: I've used those magnets before on automation projects
05:19 PM XXCoder: yeah? it seemed quite strong
05:20 PM XXCoder: he should add limits though lol so can just start and go do orher stuff keeping eye on it
05:20 PM roycroft: and the new, more transmissive strain is officially in the us now
05:20 PM roycroft: a colorado man has it
05:21 PM JT-Cave: that machine is a waste of time to just cut straight lines lol
05:21 PM JT-Cave: not good news
05:21 PM roycroft: what machine?
05:22 PM XXCoder: dunno, it seems extremely easy to setup and taking off quite lengthy time cutting is ncie savings of time
05:22 PM JT-Cave: the link XXCoder put up
05:22 PM XXCoder: https://youtu.be/IQUnEU4hdOU
05:22 PM roycroft: what really sucks is that 20 million people were supposed to be vaccinated by year's end in the usa
05:22 PM roycroft: as of today, 2.1 million have been vaccinated
05:22 PM XXCoder: lack of limit switches make it useless though
05:23 PM roycroft: somehow i doubt that another 18 million vaccines will be administered in the next two days
05:23 PM JT-Cave: just need a straight edge and a drag tip lol
05:23 PM XXCoder: does vaccine work with new strain?
05:23 PM pfred1: they said there would be no vaccine before the end of the year
05:23 PM pfred1: so anyone vaccinated I say is a win
05:24 PM pfred1: will it cure baldness?
05:27 PM roycroft: yeah, that seems to be a lot of work to cut straight lines
05:28 PM roycroft: the problem is that there are millions of doses of the vaccine warehoused, and even at ultra cold temperatures, they won't last very long
05:28 PM JT-Cave: if it had XY maybe ok for a portable plasma for on site work
05:28 PM roycroft: plus, at 2 million/month, it will take over a decade to vaccinate everyone
05:29 PM JT-Cave: your so cheerful tonight
05:30 PM JT-Cave: XXCoder, those are door magnets and can have 500 pounds of holding power
05:30 PM XXCoder: dang can hold me up
05:30 PM XXCoder: i wonder if it could contain a explosion, holding metal door shut
05:30 PM roycroft: sorry
05:31 PM roycroft: i'm trying to hold my tongue as best i can for the next three weeks
05:31 PM XXCoder: roy it always takes time to ramp up
05:31 PM roycroft: but sometimes it just hurts too much to bite down on it so hard
05:31 PM JT-Cave: I used some to lock a rotary table until the proper number of screw torques were done
05:32 PM JT-Cave: fireworks factories have strong walls and a weak roof
05:32 PM roycroft: xxcoder: especially when you put someone in charge of distribution who did not even know what a vaccine was, other than conceptually, on the day he was hired
05:32 PM XXCoder: jt didnt think of it that way. makes sense really.
05:33 PM pfred1: here they built the explosives plants with one weak wall facing the river
05:33 PM roycroft: the general who is in charge said he had absolutely no clue about it when they put him in charge
05:33 PM roycroft: he said that he would sit in meetings every day and write down every acronym that was used that he did not know, and then go home at night and study them
05:33 PM XXCoder: whats important is mission parameters and what must be done, and what must not be done
05:33 PM pfred1: people in the military can be good at logistics
05:34 PM XXCoder: pf very.
05:34 PM roycroft: yes, they can
05:34 PM roycroft: but they have to have a semblence of a clue
05:34 PM pfred1: or they don't win too many battles
05:34 PM roycroft: and that guy *is* good at logistics
05:34 PM roycroft: i'm not putting him down
05:34 PM roycroft: but he had an awful lot to learn in almost no time
05:34 PM roycroft: and there have been a lot of screwups already
05:34 PM pfred1: we don't make just anyone a general
05:35 PM roycroft: correct
05:35 PM roycroft: but not all generals are experts in everything
05:35 PM roycroft: after the interview with him, i actually felt a lot better about the vaccine distribution
05:36 PM roycroft: he's obviously not just some clueless political crony who doesn't care
05:36 PM XXCoder: indeed!
05:36 PM roycroft: he was clueless, but with the ability and the desire to learn
05:36 PM roycroft: and i'm sure he's learned a lot since then
05:36 PM roycroft: the interview was on 60 minutes a couple months ago
05:37 PM roycroft: the president promised 100 million doses by the end of the year
05:37 PM pfred1: general Groves knew nothing about science but he got the bomb built
05:37 PM roycroft: we have 20 million, and only 10% of those have been used
05:37 PM JT-Cave: hmm the boeing 737 max is back in service
05:37 PM roycroft: it is
05:38 PM roycroft: i warned folks earlier to put on their hard hats
05:38 PM pfred1: he knew how to tell people what to do
05:38 PM XXCoder: jt it is yeah.
05:38 PM roycroft: it's not any real consolation, but canadadians are behind in their vaccination schedule as well
05:38 PM XXCoder: i might get job back in a month or 2
05:38 PM JT-Cave: nice
05:39 PM roycroft: that would be great, xxcoder
05:39 PM XXCoder: hope so. i have bunch of health issues that makes it uncertain however lol
05:39 PM roycroft: especially if you can distance safely, or if everyone gets vaccinated
05:39 PM XXCoder: im still dizzy af
05:39 PM roycroft: health issues should move you to the front of the vaccine queue
05:40 PM pfred1: you can have my place
05:40 PM pfred1: I ain't taking no vaccine they rushed to develop I'll wait for version 2.0
05:40 PM roycroft: i hope that when places like concert venues and the like reopen they'll require proof of vaccination to let people in
05:41 PM JT-Cave: my youngest daughter got the vaccine they other day... she is a nurse
05:41 PM roycroft: that will make the venues safer, and will some of the more hesitant folks to get theirs
05:41 PM roycroft: i'm so ready for this to be over
05:41 PM roycroft: i can deal with another six months or so
05:41 PM JT-Cave: you and me and the rest of the world
05:41 PM roycroft: but if it goes much beyond that it's going to get very difficult for everyone
05:41 PM roycroft: yes
05:42 PM roycroft: and the sad irony is that the deniers who want to just get on with life are the ones who are prolonging the pandemic
05:42 PM pfred1: all i know is the land of the free and the home of the brave is dead to me now
05:42 PM JT-Cave: so I determined the replacement chain for the infeed/outfeed rollers is not a perfect match on the planer
05:42 PM pfred1: this country obviously isn't either
05:42 PM JT-Cave: it failed to include a half link
05:43 PM * roycroft bites his tongue again, deciding it's better to put up with the bleeding than to say anything more
05:43 PM JT-Cave: both of the local folks that I know got covid at hunting camp
05:44 PM XXCoder: sigh
05:44 PM JT-Cave: so close to planing a chunk of wood... for the need of a metric half link
05:44 PM roycroft: iirc there's a chain tensioner on my planer, but i don't think it adjusts by much
05:45 PM roycroft: can you use the old chain, or is it too stretched out?
05:45 PM JT-Cave: there is one on mine and both infeed and outfeed roller are a bit out of adjustment and I need to address that so the chain runs true
05:45 PM JT-Cave: half link will be here tomorrow
05:45 PM roycroft: or can you steal the half link from the old chain and install it on the new one for now?
05:45 PM roycroft: oh, ok
05:45 PM roycroft: that's not so bad
05:46 PM JT-Cave: old chain is all riveted
05:47 PM XXCoder: getting closer tho! :)
05:48 PM JT-Cave: the chain is an ISO 06B with 3/8" pitch... glad McMaster had good info on that
05:48 PM JT-Cave: yea I'm over the lost package parts they are installed so I just keep plugging away at it
05:48 PM pfred1: just cut it and braze it
05:49 PM JT-Cave: not sure what "it" is
05:49 PM pfred1: anything
05:50 PM JT-Cave: yeah it can be interpreted as anything there in lies the communication problem
05:51 PM roycroft: i just got a 500g package of powdered burnt umber
05:52 PM roycroft: i've been making custom stains for years, using artists oil paints
05:52 PM roycroft: they work out nicely but are still rather expensive to make
05:52 PM roycroft: i got this big bag of powdered pigment for about the same price as a tiny tube of the mixed stuf
05:53 PM JT-Cave: what do you mix it with?
05:53 PM roycroft: i don't need the oil carrier for it, but even if i did, all that stuff in a tube is is a few drops of walnut oil
05:54 PM roycroft: the artists oil paints i mix with mineral oil or denatured alcohol
05:54 PM JT-Cave: interesting
05:54 PM roycroft: the powdered stuff i'm going to try mixing in water
05:54 PM roycroft: without the walnut oil it should mix fairly well in water
05:54 PM roycroft: i'll need to get a bunch of other pigments, of course, to get the colors that i want
05:55 PM roycroft: but i figured i'd buy just the one for now, to experiment with
05:55 PM roycroft: i also want to try mixing it in epoxy to see how that goes
05:55 PM JT-Cave: did you get it from earthpigments.com?
05:55 PM roycroft: those epoxy dyes are realy expensive
05:55 PM roycroft: yes
05:56 PM roycroft: if this works out, i'll get some raw umber, and raw and burtn sienna, one of their blacks, and a green, blue, red, and yellow
05:57 PM roycroft: i should be able to make most wood stains that would interest me with those pigments
05:57 PM JT-Cave: in the primaries?
05:58 PM roycroft: the one i got is from their natural earth and ocher pigments section
05:59 PM roycroft: i think i can get everything i need from that section
05:59 PM JT-Cave: I've not done much staining yet
05:59 PM roycroft: i use dyes for most of my stuff
05:59 PM roycroft: water-based dyes
05:59 PM roycroft: but i do some staining
06:00 PM roycroft: and with porous woods i usually do some grain filling, which requires pigments
06:00 PM roycroft: i bought some framing grade green douglas for for my new library bookcase, because i did not want to spend $1k on wood for the thing
06:00 PM JT-Cave: earthpigments.com is an interesting web site
06:01 PM roycroft: it's going to work fine, but there are some cracks in the wood that i'm going to need to fill with epoxy
06:01 PM roycroft: and i want the epoxy lines to be as invisible as possible, so i need to color the epoxy
06:01 PM roycroft: i assume you're looking at their how-to section
06:01 PM roycroft: and are learning how to make all sorts of paints and stains
06:01 PM JT-Cave: all the sections yes
06:02 PM JT-Cave: just about time to start the jambalaya
06:02 PM roycroft: i'm about to head to market myself
06:02 PM roycroft: i haven't bought groceries in a week
06:03 PM roycroft: i'm deciding what's for dinner, and then i'm off
06:03 PM JT-Cave: we always eat breakfast before going to the supermarket
06:04 PM JT-Cave: but sometimes it does not help lol
06:04 PM JT-Cave: and my wife works her last day tomorrow
06:04 PM JT-Cave: I hope I can survive her retirement lol
06:04 PM roycroft: you might have to work on-site more :)
06:05 PM JT-Cave: yeah
06:05 PM roycroft: your shop may get too cramped
06:05 PM roycroft: and you may need to lease a shop in town
06:06 PM JT-Cave: I always have places to go it seems... got another spoke lathe to automate as soon as the target system is done
06:06 PM XXCoder: good job means more jobs :)
06:07 PM JT-Cave: she does have to hunt for me with two shops and a garage lol
06:07 PM roycroft: she'll proably discover some new interests
06:07 PM roycroft: be prepared to build/remodel a space for her to use to explore them
06:07 PM JT-Cave: it's funny a guy I've known for a long time is an electrician and he told the shooting range owner he needed to call me but he didn't have my number any more
06:08 PM roycroft: or maybe she'll take up birding or hiking or something
06:08 PM JT-Cave: she has 1/2 of a she shed left to use
06:08 PM roycroft: well there you go
06:08 PM roycroft: help her build it out however she needs it
06:09 PM JT-Cave: so the guy he worked for called another guy at a factory that I do work for and he called me
06:09 PM JT-Cave: I'll just have to see what her interests are
06:09 PM roycroft: yup
06:14 PM * JT-Cave wanders off to the cocina
06:15 PM roycroft: so one of tomorrow's parcels, the one i really want to have before the weekend, was shipped via fedex ground from seattle to oakland
06:16 PM roycroft: now it's on its way north from oakland, and has to drive over siskiyou summit, which has been snowed in frequently in the past few days
06:16 PM roycroft: good chance of a delay there
06:16 PM roycroft: it's already driven through eugene on its way down to oakland
06:18 PM roycroft: the road is actually clear down there right now, so perhaps it will still arrive on time
06:18 PM roycroft: even down in yreka and weed it's clear
06:36 PM JT-Cave: siskiyou is interesting sounds like an Eskimo tribe word
07:10 PM roycroft: well, no mail today, for the third day in a row
07:10 PM roycroft: i passed my letter carrier on my way home from market, and she was heading back towards the post office
07:10 PM roycroft: my parcels were all marked out for delivery again today
07:31 PM veegee: I ruined an HSS endmill by using too high an RPM. The end was glowing red hot and is very dull
07:31 PM veegee: just the last 0.5mm where all the interesting stuff happens
07:32 PM veegee: so can I fix it by cutting off the end on a lathe using a carbide cutter?
07:32 PM XXCoder: wouldnt grinder be better?
07:32 PM veegee: Yes but I don't have a surface grinder yet
07:33 PM veegee: I only have a bench grinder and the face of the endmill needs to be perfectly flat
07:34 PM XXCoder: lathe and grinder? make a attachment
07:34 PM XXCoder: can move it across face with grinder with enough precision that its very flat
07:35 PM veegee: you mean find a way to mount a grinding stone onto the lathe/
07:35 PM XXCoder: that sounds better yeah lol
07:35 PM veegee: or you mean make a jig to move the endmill across the bench grinder?
07:36 PM veegee: I don't want to put a grinding stone anywhere near machine tool slideways
07:36 PM XXCoder: i meant attach grinder to lathe, but your idea is far better. yeah powder from that is an issue hm
07:36 PM veegee: I don't mind buying a surface grinder. I mean not just for this, I put a watch on ebay and kijiji for a good price for the last few months
07:36 PM veegee: So I'm getting one at some point
07:37 PM veegee: I also have carbide burrs
07:38 PM veegee: I could try using that on the vertical mill
07:39 PM veegee: Then again it's not a super expensive endmill, just a few dollars
07:40 PM veegee: I don't know why I bought a HSS kit to begin with. Should have just gone pure carbide but those are 10x the cost
07:41 PM _unreal_: now yall talk
07:41 PM _unreal_: sigh
07:41 PM _unreal_: !I saw the word epoxy whats up?
07:45 PM roycroft: hss is a lot stronger than carbide
07:45 PM roycroft: i don't see hss vs. carbide
07:45 PM roycroft: i see hss + carbide, and use the tools that's best for the application at hand
07:45 PM veegee: yeah that's true
07:46 PM veegee: I was milling mild steel and went too high with the RPM. Even with cutting oil, the tip overheated
07:46 PM roycroft: i think most folks start out with hss because it's more versatile and a lot less expensive than carbide, then start getting carbide tooling as their budget and project needs dictate
07:48 PM roycroft: getting tooling made of alloys like m-15 or m-42 is often a good compromise
07:48 PM roycroft: especially if you don't have a continuous coolant system
07:48 PM veegee: Tried that, they still dull super quick when drilling spring steel and such
07:49 PM roycroft: carbide tooling will almost explode when subjected to sudden temperature changes
07:49 PM veegee: tungsten carbide is the only thing that's never failed me
07:49 PM roycroft: you either run your carbide tooling hot, with no coolant, or you run it with continuous cooling
07:50 PM roycroft: no dabbing a little oil on it once in a while, or shooting it with a spray bottle
07:50 PM roycroft: and carbide will chip if you look at it funny
07:50 PM veegee: I have compressed air blowing at it constantly
07:50 PM roycroft: so there are some real drawbacks to it
07:50 PM veegee: I've never had it chip. I run it at very high speed with light passes
07:51 PM roycroft: but on the other hand, while you can't get it as sharp as hss, it will hold what edge it has for longer than hss, and you can machine a lot faster with it
07:53 PM veegee: _much_ longer than HSS
07:53 PM veegee: I've never worn out a carbide tool at the rate I use them. I've worn out so many HSS tools
07:54 PM veegee: they're perfect for wood or aluminum, but as soon as you get to medium/high carbon steels, there goes your tool life
07:56 PM veegee: If I want to drill a hole in a forklift fork, I wouldn't even try with an HSS annular cutter. It'll just ruin it
07:56 PM XXCoder: think carbide is expensive? ytry cobolt lol
07:56 PM veegee: It's cheaper than solid carbide endmills
07:57 PM XXCoder: hmm im not certain but i dont think company i worked at employs partial carbide?
07:57 PM veegee: carbide tipped vs solid carbide that is
07:58 PM roycroft: you must not machine steel very often
07:58 PM roycroft: i do not do a lot of machining, and i've gone through a lot of carbide inserts
07:58 PM roycroft: i mostly machine steel though
07:58 PM roycroft: probably 80% of my milling and turning is steel
07:59 PM roycroft: a forklift fork is hard steel
07:59 PM veegee: Same here
07:59 PM veegee: yes it's tempered high carbon steel. Not as hard as HSS, but it will dull it fast
08:01 PM XXCoder: roycroft: im not certain because i dont select tools at that work
08:02 PM XXCoder: dont think I ever seen carbide tipped, just solid ones
08:02 PM XXCoder: cobolt I menioned is all flute is cobolt, rest is carbide
08:03 PM roycroft: annular cutters are never solid carbide
08:03 PM roycroft: larger end mills rarely solid carbide
08:03 PM roycroft: they're eithe carbide tipped or have carbide inserts
08:05 PM pfred1: I like machining HDPE
08:05 PM pfred1: it's easy on cutters
08:05 PM XXCoder: watch out nylon lol
08:05 PM XXCoder: tools last forever... as long as you constantly spray coolant on it
08:05 PM XXCoder: otherwise it will be enclosed in plastic
08:06 PM pfred1: HDPE is basically hardened lubricant
08:06 PM roycroft: i machine whatever material my part needs to be
08:06 PM XXCoder: its great plastic yeah
08:06 PM XXCoder: I want to try mill it someday
08:07 PM pfred1: well I've had issues with it warping sometimes
08:07 PM XXCoder: i want to also try melt it into hot oil (not smoking) and then compress to get nearly all oil back out
08:07 PM XXCoder: then its even more lubucating
08:07 PM pfred1: HDPE is already pretty slippery
08:08 PM pfred1: I've made stuff out of it and had issues with it not having enough friction
08:08 PM XXCoder: yep thats why im saying it'd be interesting play around test. its not like i will run out of hdpe.
08:10 PM XXCoder: i also want try same thing with store bags and LDPE
08:10 PM XXCoder: problem is that those bags dont exist here anymore
08:10 PM pfred1: it takes a lot of bags
08:10 PM XXCoder: very good for envorment though, stopping those bags
08:10 PM pfred1: you can make something that looks like Damascus plastic melting bags though
08:11 PM pfred1: if you alternate the colors
08:11 PM pfred1: like white and black bags
08:11 PM XXCoder: https://youtu.be/uUEKtOGmpVI interesting
08:11 PM XXCoder: nice
08:11 PM pfred1: but use like 5 in each layer because one bag is nothing
08:12 PM pfred1: they melt up to nothing
08:12 PM XXCoder: yep. very strong for "nothing" though
08:12 PM pfred1: what you end up with is definitely an interesting material though
08:12 PM XXCoder: hdpe is tough. too bad its too hard to print with.
08:12 PM pfred1: yeah HDPE does not flow when it melts
08:13 PM pfred1: just gets gooey
08:13 PM pfred1: it's like hot glue kind of
08:13 PM XXCoder: wonder if theres a way to design around that
08:13 PM XXCoder: ie new hotend design
08:13 PM pfred1: I am an HDPE snob now i only do the clear jugs
08:14 PM pfred1: HDPE without color is harder and slicker
08:14 PM pfred1: they add binders when they color HDPE
08:15 PM pfred1: if you ever melt HDPE try to use a convestion oven too
08:15 PM pfred1: convection even
08:15 PM pfred1: makes a bit difference
08:16 PM XXCoder: cool :) you mean milky white? like on milk jugs
08:16 PM pfred1: yes
08:16 PM XXCoder: i wonder if drying it first before bake would make it even better
08:16 PM pfred1: milk and water jugs have no coloring
08:16 PM pfred1: the only real trick is don't burn it
08:16 PM XXCoder: milk caps make for really fanastic color plastic
08:17 PM XXCoder: saw em in video
08:17 PM pfred1: the caps are LDPE
08:17 PM XXCoder: i know :)
08:17 PM CaptHindsight: garbage material in, garbage out
08:17 PM pfred1: don't melt soap jugs
08:17 PM pfred1: I had a Tide bottle was this cool orange so I melted it
08:17 PM pfred1: man the smell was unreal!
08:18 PM XXCoder: cleaned it super clean first?
08:18 PM pfred1: yeah there's no cleaning the perfume out of the plastic
08:18 PM XXCoder: too bad
08:18 PM pfred1: and baking it the smell really comes out
08:18 PM XXCoder: does it evenually air out?
08:18 PM pfred1: not really no
08:18 PM CaptHindsight: some people pay extra for scented plastics
08:18 PM XXCoder: im thinking hot cook plate outside set to just below melt, with fan cross it
08:19 PM pfred1: some people use them panini cookers
08:19 PM pfred1: George Foreman grills
08:19 PM pfred1: I saw a woman ironing bags in a video
08:19 PM pfred1: she would put parchment paper over them or something
08:20 PM CaptHindsight: I generally like panini
08:20 PM pfred1: one guy on YouTube was the king though he'd bandsaw up plastic buckets
08:21 PM pfred1: stack the pieces in a pan and get amazing designs
11:07 PM mrec: can anyone recommend some good clamps for acrylic? The default metal clamps are ok but are colliding with the outer diameter of the collet so I need to have some extra dead space
11:40 PM unterhaus_: have you looked at 3d printed clamps?
11:42 PM unterhaus_: 3d printed hold down clamps are common on thingiverse
11:49 PM mrec: I have just designed one it's printing
