01:18 AM Deejay: moin
03:58 AM Loetmichel: *grrr* Always the eye. *Takes Qtip and removes alu sliver from eyeball* Circular saw and alu is a bad combination, even with protection glasses :(
03:59 AM XXCoder: maybe wear head protection with goggles?
03:59 AM Loetmichel: i did wear protection googles AND ear protection. it managed to slip around the googles
04:00 AM XXCoder: yeah thats why i suggested face protection too
04:00 AM XXCoder: :)
04:00 AM Loetmichel: you mean like a face shield like for chainsawing?
04:00 AM XXCoder: yeah
04:06 AM gloops: look after the eyes, just remember youll never watch pornhub again when theyve gone
04:08 AM XXCoder: if I lose my eyes I lose ability to listen to others
04:19 AM Loetmichel: thats because you are deaf?
04:19 AM gloops: yeah life changing, a finger, even a leg you can restore some kind of normality
04:19 AM Loetmichel: and yes, i do look after my eyes. hence me so pissed that the sliver managed to get around the googles
04:20 AM Loetmichel: gloops: i remember the sign in the laser lab at uni: "Protect your remaining eye!"
04:20 AM gloops: lol
04:21 AM Loetmichel: ... and they say germans have no (black) humor ;)
04:22 AM gloops: i did a safety course in my teens, watching a film, the room was rowdy nobody paying much interest, then a photo of this attractive girl comes on the screen and the guy says - remember youll never see anything like this again
04:22 AM gloops: room went silent - everyone was like oh sht eyes are important
04:22 AM Loetmichel: > everyone was like oh sht eyes are important <- do tell!
04:22 AM Loetmichel: :)
04:24 AM gloops: it stuck with me, theres always those times when youre in a mad rush though, or left glasses somewhere - ill just grind this up only take a second
04:24 AM gloops: i guess thats when it happens
04:32 AM Loetmichel: yep
05:06 AM JT-Cave: morning
06:52 AM Tom_L: morning
07:16 AM gloops: well, metal lathe is dead so may as well try and the chucks on wood lathe, adaptor only £20 https://www.ebay.co.uk/itm/Precision-Thread-Adaptor-1-x-8tpi-Male-to-1-x-12tpi-Female/114520795831?
07:16 AM gloops: if it fits
09:21 AM roycroft: what a blustery day
09:21 AM roycroft: very march-like - windy, rainy, generally inhospitable
09:41 AM enleth: Loetmichel: this is probably somewhat dependent on individual face shape, but I've recently switched to using Honeywell Ignite safety glasses exclusively due to the *perfectly* tight fit they have against my brows, cheeks and the area towards the ears
09:41 AM enleth: maybe try them, they could be a proper fit for you as well
09:41 AM enleth: their anti-fog layer works pretty well, too
09:43 AM enleth: this thing: https://www.amazon.com/Honeywell-Metallic-Frameless-Anti-Fog-RWS-51037/dp/B001ULCHKE
09:44 AM enleth: I actually bought them to see if the anti-fog feature works as advertised, but kept them for how well they protect against crap getting through the sides
10:02 AM mateusz is now known as Guest59879
10:06 AM matkoniecz: Is installing LinuxCNC means installing a separate OS?
10:07 AM matkoniecz: linuxcnc.org/docs/2.8/html/getting-started/about-linuxcnc.html has "LinuxCNC is available as ready-to-use packages for the Ubuntu and Debian distributions."
10:07 AM matkoniecz: but I see .iso files for download
10:07 AM roycroft: the iso images are for a turnkey installation
10:08 AM roycroft: but you can install it as a package if you wish
10:08 AM roycroft: to use it with real hardware you'll need a real time kernel
10:09 AM gloops: you cant install it on windows, it is the operating system, you need a separate hard drive
10:09 AM perry_j1987: or partition
10:10 AM gloops: yeah
10:11 AM roycroft: correct, although since matkoniecz quoted the bit about being available for ubuntu and debian i made what i thought was the safe assumption that he was aware that linux is a requirement
10:11 AM matkoniecz: OK, so I am not misintrerpreting documentation.
10:11 AM roycroft: but assumptions, no matter how safe, have a way of biting people in the arse
10:11 AM matkoniecz: I am posting from Linux, so Linux is not trouble by itself
10:12 AM roycroft: correct
10:12 AM gloops: people have it running on mint and so on
10:12 AM matkoniecz: Though I would rearrange partitions on my laptop (or install on external drive...)
10:12 AM roycroft: but as i said, if you want to actually control a machine with your linuxcnc installatin you need a real time kernel
10:12 AM matkoniecz: As I want to control actual laser cutter.
10:12 AM roycroft: the stock kernel is not going to work
10:13 AM JT-Shop: nor will a laptop
10:13 AM matkoniecz: One more question - is there some standard tool for generating gcode instructions from SVG file, for laser cutter?
10:13 AM matkoniecz: Or recommended one?
10:14 AM matkoniecz: So far I was using LightBurn, and linuxcnc replaces only half of it
10:14 AM roycroft: http://www.scorchworks.com/index.html
10:14 AM roycroft: https://jtechphotonics.com/?page_id=2012
10:14 AM roycroft: one or both of those may be useful, depending on your hardware particulars
10:15 AM roycroft: jt-shop: you were asking, so roycroft.us/Bandsaw
10:19 AM JT-Shop: thanks
10:24 AM JT-Shop: I like the "drawer"
10:24 AM roycroft: i have a few tweaks to do on the machine still, but it's fully functional now
10:25 AM roycroft: that is working out nicely, except i absolutely must the the blades together before hanging them in there - i put one in loose, and it got caught when i tried opening the drawer
10:25 AM roycroft: i use pipe cleaners cut in half for the ties
10:25 AM roycroft: they last longer than anything else i've tried
10:26 AM roycroft: must tie the, rather, but you probably figured that out
10:27 AM roycroft: the new fence is a bit oversized for the machine, but i was able to get it to fit decently
11:48 AM unterhaus_: roycroft, remind me what fence that is again?
11:48 AM roycroft: shopfox
11:49 AM roycroft: https://www.amazon.com/gp/product/B005W0YDBK
11:49 AM roycroft: you can buy the exact same fence from grizzly for $50 more, if you wish
11:55 AM unterhaus_: thanks. It says last one, you think amazon really knows what they have in stock?
11:55 AM Loetmichel: enleth: its not the first time that happened. Last time it was a bit of red hot grinding disc though. a lot more unpleasant than a mere alu sliver.
11:55 AM roycroft: they have a pretty good idea
11:55 AM roycroft: it's what they do
11:56 AM roycroft: it's a really nice fence
11:57 AM roycroft: i cut 7" off the rails of mine to make it fit better
11:57 AM roycroft: folks complain that it's not adjustable for parallelism, but they are wrong - it is adjustable
11:57 AM unterhaus_: I have a 16" saw so it will fit better. I like your blade holder, I'll have to do something like that
11:58 AM roycroft: yeah, it should be perfect for a 16" saw
11:58 AM Loetmichel: maaan... will i ever learn not to start CNC programs that will run for hours short before ending of workday? ANOTHER 1.5h overtime just sitting there waiting :(
11:58 AM unterhaus_: as long as it's not unpaid overtime
11:58 AM roycroft: i used to store moy bandsaw blades on a hook well overhead - i needed to use a stick to reach up and grab them
11:58 AM roycroft: storing them right in the machine base is a significant improvement
11:59 AM roycroft: it's friday
11:59 AM unterhaus_: I have a blade drawer on my tablesaw base, but bandsaw blades are not welcome in there
11:59 AM roycroft: never do any big job on a friday
11:59 AM roycroft: a vertical drawer would be nice for storing tablesaw blades/inserts as well
11:59 AM unterhaus_: never start a simple plumbing job within 5 hours of quitting time
11:59 AM roycroft: i'm considering that when i build my new tablesaw cabinet
12:00 PM unterhaus_: only problem with my tablesaw cabinet is it's full of projects that I'm not getting around to
12:00 PM unterhaus_: better than the pre-cabinet days though
12:00 PM roycroft: mine is too small for the saw, and it was built very strangely by the previous owner of the saw
12:00 PM roycroft: but i've put up with it for years
12:00 PM roycroft: it's on my list to replace
12:01 PM roycroft: i built a new base for my drum sander last year, and i just finished the bandsaw base
12:01 PM roycroft: i need to build a cabinet to fit under my drill press next
12:01 PM roycroft: and then rebuild my router table
12:01 PM roycroft: then hardware storage cabinets, and then the tablesaw cabinet
12:01 PM roycroft: there are a lot of shop projects to do still, but when they're done it should be a very efficient workspace
12:02 PM roycroft: i waste so much time walking around to get things, and moving things out of the way
12:02 PM unterhaus_: amazon just decided I speak spanish, the jerks
12:03 PM unterhaus_: okay, ordered the fence finally. The one I hacked together was not working for me
12:03 PM roycroft: it is heavier than you think
12:04 PM roycroft: the main fence arm is cast iron
12:04 PM roycroft: it has a ground face, so you don't have to use that aluminium resaw bit if you don't need it
12:06 PM Rab: roycroft, that bandsaw looks very nice. Did you restore it, or build (parts) of it from scratch?
12:07 PM roycroft: it's an old grizzly saw that i bought 20+ years ago
12:08 PM roycroft: i bought it new at the time
12:08 PM roycroft: i'm going to be doing a lot of resawing, so i got a bigger motor (2hp), and decided to install the 6" riser block permanently
12:08 PM roycroft: it has a 12" resaw capability now
12:09 PM roycroft: i was going to buy a new saw, but decided in the end to just remodel the existing one
12:09 PM roycroft: a primary reason being that all the new saws i was looking at were a wee bit too tall to roll out through my garage door
12:09 PM roycroft: the current one was as well, so i decided to build a new base that is a bit shorter so it would fit
12:10 PM roycroft: and that got me into doing a total rebuild of the saw
12:10 PM roycroft: it also finally has a magentic switch on it, which i think should be mandatory for any stationary machine
12:11 PM roycroft: the new motor was too big for the old base anway
12:11 PM roycroft: anyway
12:11 PM unterhaus_: I imagine that resaw blade would really like to unfold
12:11 PM unterhaus_: I was proud of myself when i managed to fold mine up
12:11 PM roycroft: you can see from the pics that the new base sticks out the front farther than one would desire, but the bigger motor barely fits in it
12:11 PM unterhaus_: only minor injuries
12:11 PM Rab: roycroft, the understated wood trim is "clutch", as the kids say. Great complement to that shade of green.
12:12 PM roycroft: i have a pair of thick leather gloves that i use for handling blades
12:12 PM roycroft: yeah, that turned out nicely
12:12 PM roycroft: the wood is birch, which i don't generally find very attrative, but tried & true oil varnish makes it look really nice
12:13 PM roycroft: there's a plastic filler piece that came with the saw, but it does not fit properly with the 6" riser block installed
12:13 PM roycroft: so i made a wood filler for it
12:13 PM roycroft: i spent a lot of time picking that paint color, and i'm pretty happy with it in the end
12:14 PM roycroft: as you said, it matches nicely with the wood trim
12:14 PM roycroft: i wanted a "retro" look, and i think i achieved it
12:15 PM roycroft: unterhaus_: the easiest way i've found to fold up bandsaw blades is to hold the blade in front of you in both hands with your left thumb facing up and your right thumb facing down
12:16 PM roycroft: rotate your thumbs simultaneously towards each other and the blade will coil up nicely
12:16 PM roycroft: you can reverse the direction, of course - just make sure your thumbs face in opposite directions when you start out
12:17 PM unterhaus_: I have to watch a youtube every time
12:17 PM roycroft: a lot of folks like the method of standing on the blade and twisting/pushing it down, but i find the opposing thumbs method the easiest for me, personally
12:17 PM unterhaus_: I'm not going to remember it next time I have to do it
12:17 PM roycroft: well go do it five times right now
12:17 PM roycroft: then you'll remember
12:17 PM unterhaus_: nah
12:17 PM unterhaus_: mind is gone
12:18 PM unterhaus_: I have trouble remembering where the refrigerator is
12:18 PM roycroft: i change blades all the time, so having to look it up every time would be annoying
12:18 PM roycroft: that's why the blade drawer is such a win for me
12:18 PM unterhaus_: maybe if I start using my bandsaw more
12:18 PM roycroft: it will save me heaps of time
12:18 PM roycroft: and that's also why i like to get a dedicated set of tools for adjusting each machine, and keeping the tools with the machine
12:19 PM unterhaus_: I folded the resaw blade on the deck, needed a bit of persuasion to fold right
12:19 PM roycroft: two allen wrenches are all i need to make any of the standard adjustments on the bandsaw, and i have dedicated allen wrenches for that
12:20 PM roycroft: i still need to make a holder for them - that is one of the tweaks that i need to do yet
12:20 PM unterhaus_: where do you buy single hex wrenches?
12:20 PM roycroft: a couple local hardware stores sell the l-shaped ones
12:20 PM roycroft: i like ball end tee-handle ones, and i usually get those individually on ebay
12:21 PM unterhaus_: well, that's out, the only local hardware store gave up, too much work
12:21 PM roycroft: https://www.ebay.com/itm/262191991477
12:21 PM roycroft: for example
12:22 PM roycroft: that one is not a ball-end, but they can be had with a wee bit of effort
12:29 PM unterhaus_: the machine that most needs its own tools is my lathe, but I am thinking about just moving the tool chest closer to it
12:29 PM unterhaus_: every shop has at least one tool chest
12:32 PM roycroft: i built a stand for my lathe, and built two drawer units to fit in the stand
12:32 PM roycroft: so there is tool storage for the lathe in those
12:33 PM roycroft: i'm at a point in my life where i have a pretty complete set of hand tools - i'm not in the stage where i'm buying tools every month to build up the set
12:33 PM roycroft: so i can afford to buy machine-specific tools now, which really save me a lot of time
12:33 PM roycroft: but yeah, if you do that, pick the machine where it will be most useful first
12:35 PM Eric__: There are a couple of tools that would be nice to have on the lathe. But the most pressing storage issue is for tool holders
12:35 PM roycroft: mine are in a drawer right now
12:35 PM Eric__: right now, they are covering half of my jointer
12:35 PM roycroft: i need a backsplash for my lathe - i was doing some turning last week and chips flew all over the shop
12:36 PM Eric__: yeah, I have considered having one made by the local sheet metal shop. Only complication is the taper attachment
12:36 PM roycroft: when i build the backslash i'd like to design it so that i can install a tool holder holder on it
12:36 PM roycroft: i don't have a taper attachment for mine
12:36 PM Eric__: I've seen that, it's a good idea
12:36 PM roycroft: it would be a very convenient way to store them
12:36 PM Eric__: tbh, I wish I didn't have a taper attachment on miine
12:37 PM roycroft: i've never missed having one
12:37 PM roycroft: i'm not sure if one was ever made for my lathe
12:37 PM Eric__: I suppose if you use it, it becomes handier
12:37 PM roycroft: but there are other ways to cut tapers
12:37 PM Eric__: I don't have the need to cut many long tapers. Short tapers can be cut with the compound
12:38 PM roycroft: a lot of folks are scared to offset the tailstock, because they think it's too much work to align it again after the taper cut
12:38 PM Eric__: mine seems to offset itself, need to work on that
12:38 PM roycroft: but i've found that if i us an indicator to do the offset, which is the easiest way i've found to get the offset correct, i can just use the indicator again to realign it when i'm done
12:39 PM roycroft: and that's good enough for the type of work i do right now
12:39 PM Eric__: It's a quick job
12:39 PM roycroft: my skills and my machine are not up to holding tenths
12:39 PM Eric__: mine was a beautifully precise machine when it left the factory
12:39 PM roycroft: perhaps some day, but not now
12:40 PM Eric__: after it left the high school auto shop, not so much
12:40 PM roycroft: mine is an old jet - made in taiwan in the '80s
12:40 PM roycroft: and lived in a high school machine shop for 30 years
12:40 PM roycroft: it's fairly beat up
12:40 PM roycroft: but i can make parts with it
12:40 PM Eric__: apparently you can cut threads on it at high speed
12:40 PM Eric__: the apron needs work to do that, it was locked up when I got it
12:41 PM Eric__: I think they might have worn something out grinding car brake discs
12:49 PM JT-Shop: 4 more parts to make then I'm knocking off for the rest of the day if the boss is not looking
12:52 PM Tom_L: sneak out the back
01:06 PM JT-Shop: no back door...
01:11 PM XXCoder: he didnt say out of door ;)
01:22 PM -!- #linuxcnc mode set to +v by ChanServ
01:48 PM andypugh: roycroft: Coaxial inidcator in the chuck..
01:48 PM roycroft: yes, if one has one
01:48 PM andypugh: One doesn’t?
01:49 PM roycroft: i suspect many do not
01:50 PM andypugh: There are some reasonably cheap ones out there. https://www.ebay.co.uk/itm/352934011915 as an example.
01:50 PM andypugh: Though they are all a bit long.
01:52 PM roycroft: i've read/heard that the inexpensive ones do not work very well
01:52 PM roycroft: if you think othrwise i'll reconsider, for sure
01:52 PM roycroft: i've often wished i had one
01:53 PM roycroft: but not enough to spend several hundred dollars on one
01:55 PM Tom_L: i just got my kid a brown & sharp one that seems nice
01:56 PM roycroft: https://www.ebay.com/itm/143447714650
01:56 PM roycroft: this is the low end of what i've considered to date
01:56 PM Tom_L: err no it was fowler
01:56 PM andypugh: I have a cheap one, and it has been exactly as good as itself. I have nothing with which to compare it.
01:57 PM Tom_L: https://www.fowlerprecision.com/Products/Coax-Indicator/527100250.html
01:57 PM Tom_L: i looked at those too and got the fowler
01:57 PM XXCoder: andy maybe get one of those gage bore
01:57 PM XXCoder: so can measure it and see how good it is
01:57 PM XXCoder: wrong word
01:57 PM XXCoder: gage holes?
01:58 PM andypugh: I can try that. I have one engraved “1.400004”
01:58 PM roycroft: fowler seem to be a pretty good brand
01:58 PM XXCoder: whats it called again>?
01:59 PM andypugh: Well, this one is a bore micrometer standard
01:59 PM roycroft: not the top-of-the line stuff like b&s or mitutoyo or starrett, but better than the standard no-name chinese imports
02:03 PM XXCoder: thanks
02:23 PM Eric__: I swear the average sheldon owner is barely literate given their emails
02:41 PM roycroft: i believe the average age of a sheldon owner is 97
02:46 PM Eric__: I try to help the ones with the same model as I have and then most of them go radio silent
02:46 PM Eric__: I shouldn't let that bother me
02:47 PM roycroft: i have a sheldon horizontal mill
02:47 PM Eric__: I want to change mine to use linuxcnc so I can cut threads
02:47 PM Eric__: electronic gearing, not cnc
02:48 PM roycroft: i'm not unfamiliar with the sheldon mailing lists
02:48 PM Eric__: ^metric threads
02:48 PM Eric__: well, they changed from yahoo which is a much friendlier interface for 97 year olds
02:48 PM roycroft: there's no 127 tooth change gear for sheldon lathes?
02:48 PM Eric__: now they are on groups.io
02:48 PM roycroft: yes, i know
02:49 PM Eric__: they didn't make any, some people have 3d printed them
02:49 PM roycroft: i wasn't aware of that
02:49 PM Eric__: this model didn't use change gears, you have to add them
02:49 PM roycroft: i should think there would be aftermarket change gears
02:49 PM Eric__: it goes from incredibly simple to incredibly complicated gear train
02:50 PM Eric__: it had an incredibly complicated gearbox which didn't have a 127 tooth option
02:50 PM Eric__: seems like an oversight
02:51 PM Eric__: there is a place for the shaft to add a gear and the rest of it has to be fabricated
02:51 PM Eric__: originally it had a timing belt and 3 pulleys
02:52 PM roycroft: sheldons are odd machines
02:52 PM roycroft: very well built
02:52 PM Eric__: this one was really nice before the kids got to it
02:52 PM roycroft: but scaled down from the common job shop machines
02:52 PM roycroft: and full of quirks
02:53 PM Eric__: toolroom "R" series were very different. Almost look modern
02:53 PM roycroft: my horizontal mill has a mechanical power feed for the x axis
02:53 PM Eric__: but it was so expensive they didnt' make many
02:54 PM Eric__: I thought mechanical power feeds were relatively common on horizontals
02:54 PM Eric__: although I have only used 2
02:54 PM roycroft: i'm not sure about that
02:54 PM roycroft: this is the only one i've ever used
02:54 PM Eric__: and the second one I used was for breaking rocks or something like that
02:55 PM roycroft: i've seen other, larger ones that have an electrical power feed
02:55 PM roycroft: but i'm the farthest from an expert on them
02:55 PM Eric__: yeah, me neither, it's just that I have used mechanical feeds so it's not unhear-of
02:55 PM roycroft: the one on my machine would certainly not be allowed by osha these days
02:56 PM Eric__: I wish I could find a smaller horizontal, but putting it in the shop is a nightmare I really don't want to think about
02:56 PM Eric__: Almost bought a nichols once
02:57 PM roycroft: i've actually never used mine
02:57 PM roycroft: i bought it from a guy really cheap
02:57 PM Eric__: the horizontals I have used were definitely safety risks
02:57 PM roycroft: it was his parts machine
02:57 PM roycroft: the mill itself was complete, but there was no stand for it
02:57 PM roycroft: i did get to use his briefly though
02:57 PM roycroft: i bought a stand for it
02:58 PM Eric__: I want one to miter tubing for bikes
02:58 PM Eric__: but really, I do just fine hand filing
02:58 PM roycroft: but it also has a 3 phase variable speed motor that does the speed changes mechanically but moving the sheave halves in and out
02:58 PM roycroft: it's a pretty funky setup
02:58 PM roycroft: my plan was and is to just install a vfd and put a standard sheave on it
02:59 PM Eric__: that's how a bridgeport mill works
02:59 PM roycroft: it's one of those projects that i've never gotten around to
02:59 PM Eric__: I would really like to put a servo motor on the spindle but getting the mill to work first seems like t he proper order of tasks
02:59 PM roycroft: i actually have started a number of times, but i need to disassemble it to replace some shims
03:00 PM Eric__: no thanks
03:00 PM roycroft: and there's a taper pin holding one of the handles on its shaft that is stuck
03:00 PM roycroft: i think the taper pin was installed backwards and then pounded in, so it's totally wedged
03:00 PM roycroft: that is what keeps stopping me from getting the machine going
03:00 PM XXCoder: wow this is cool https://www.reddit.com/r/interestingasfuck/comments/lvu8c3/using_lasers_to_make_sure_youre_drilling_straight/
03:00 PM XXCoder: i wonbder how long before its standard ;)
03:01 PM roycroft: sadly i did not notice it when i bought the machine, but then, i only payd $200 for it
03:01 PM roycroft: that's almost scrap value
03:01 PM XXCoder: roy can drill it out?
03:01 PM roycroft: possibly
03:01 PM roycroft: but if i did i'd have to do it very carefully
03:02 PM XXCoder: or edm if its small enough
03:02 PM roycroft: and there's no way i can mount it in a drill press or anything
03:02 PM roycroft: it has to be done as it stands
03:02 PM roycroft: so either freehand, which is pretty scary, or i'd have to make a fixture to hold the drill
03:02 PM Eric__: I had to drill out a taper pin on my lathe. Not that bad
03:02 PM XXCoder: maybe build a guide
03:02 PM Eric__: buying new taper pins is weird though
03:02 PM XXCoder: use steel pipe that just fits it
03:02 PM roycroft: if i'm honest, i could probably do it in a day if i ever picked the day and just focused on it
03:03 PM roycroft: eric__: there are other identical taper pins on the machine
03:03 PM Eric__: sheldon told me the wrong size taper pin to buy
03:03 PM roycroft: if i drill out this one i can easily measure a different one to get the dimensions
03:03 PM Eric__: I didn't fully understand how to size them, the taper is the same they come in different parts of the cone
03:05 PM Eric__: there is no way that the pin sheldon said to use would work, so here's to you mr Sheldon engineer
03:08 PM roycroft: i'm a lot more worried about getting the old one out than getting a replacement to fit
03:12 PM Eric__: it's just the inconvenience of reordering
03:13 PM Eric__: once again, I'm reminded I should take notes because I'm going to have to figure out which pin to buy after doing it before
03:13 PM Eric__: you have to buy a lifetime supply from mcmaster because they cost $$$ on amazon
03:13 PM Eric__: I wonder if the fastenall out at the mall has them. probably have to buy a lifetime supply from them too
03:14 PM Eric__: I think the number of taper pins in the landfill probably outnumber the ones in use by a factor of 5 or more
03:14 PM Eric__: Work threw out about 100 pounds of them back when I didn't need any
03:15 PM roycroft: you have a lathe
03:15 PM roycroft: you can make taper pins
03:15 PM Eric__: and a taper attachment
03:15 PM Eric__: have to think about that. The only advantage is learning how to use the taper attachment
03:16 PM Eric__: because I'm sure I'll end up ordering them after I screw it up 5 times
03:16 PM roycroft: well as of now you're avoiding the whole issue
03:17 PM roycroft: so if you try making them and fail, at least you'd be doing something
03:17 PM roycroft: and your failure would inspire you to order them
03:17 PM roycroft: compared to doing nothing that's a win
03:18 PM XXCoder: oh man. laughing so hard
03:18 PM XXCoder: https://media.discordapp.net/attachments/343070336084082708/817502750497046528/155363572_10226103378597378_5848609339993020266_n.png?width=445&height=593
03:18 PM Eric__: I have to take the apron of first
03:19 PM Eric__: ^off
03:19 PM XXCoder: they didnt do research, them old navy
03:19 PM XXCoder: in asl, that means fucking or intercourse
03:19 PM XXCoder: guy in picture is my friend's friend. hes deaf like me.
03:19 PM Eric__: the peace sign, or two peace signs?
03:20 PM XXCoder: https://www.signasl.org/sign/fucking
03:21 PM Eric__: so the hippies were in on it
03:21 PM Eric__: do you have to smack your other hand to get the full meaning?
03:21 PM Tom_L: it just wouldn't be the same now would it?
03:21 PM XXCoder: yeah couple times
03:22 PM Eric__: It would not surprise me at all to learn that the hippie that invented the peace sign knew this
03:22 PM XXCoder: note its not fixed thing, standard is 2 but you can repeat it more times to add that its been loooong fuck or hit it harder
03:23 PM XXCoder: Eric__: asl is over 200 years old..
03:23 PM XXCoder: and whats with your anti-hippie thing?
03:23 PM XXCoder: im not one, but i just dont get why you went to hippie thibng
03:24 PM Eric__: it's the peace symbol
03:24 PM Eric__: https://en.wikipedia.org/wiki/V_sign
03:25 PM Eric__: I'm a little surprised you don't know that usage
03:25 PM XXCoder: or v for victory
03:25 PM XXCoder: I know.
03:25 PM XXCoder: its just more than single thing. V isn also for V
03:25 PM XXCoder: (asl fingerspell of V)
03:26 PM Eric__: the bag has someone making the peace sign, like was extremely common among hippies in the '60s and '70s
03:26 PM XXCoder: its not peace sign
03:26 PM XXCoder: its fucking sign :)
03:28 PM XXCoder: whats wrong with peace sign though?
03:29 PM Eric__: the wikipedia article I linked failed to make that connection
03:29 PM XXCoder: not just hippies use em ya know ;)
03:29 PM Eric__: I didn't say there was anything wrong with it, but it's more widely known as the peace sign
03:29 PM Eric__: hippies invented it
03:29 PM Eric__: or maybe the beatles, history is unclear
03:29 PM XXCoder: yeah though in asl how you pose stuff matters so much more
03:30 PM XXCoder: having 2 hands in that pose together we'd read it as fucking and not peace
03:30 PM Eric__: it appears that there are at least three meanings in asl, two of which are perfectly safe for work
03:30 PM XXCoder: we'd have more peace if more people fucked though lol
03:31 PM XXCoder: V for victory, peace, V, and if 2 together in that pose, fucking
03:31 PM Eric__: that's why I say the hippies knew what they were up to, they were fond of fucking
03:31 PM XXCoder: lol
03:33 PM Eric__: apropos of nothing, I have often thought it would be useful to have irc to speech
03:33 PM XXCoder: that'd work for blind yeah
03:33 PM XXCoder: they can just use errrm 6 or 8? button keyboard to say stuff
03:34 PM XXCoder: add button for return
03:34 PM Eric__: blind lcnc users must be fairly rare though
03:34 PM XXCoder: if any exists. there is blind cnc operators however
03:34 PM XXCoder: lighthouse company
03:35 PM Eric__: I have know blind woodworkers, which seems a little more tricky
03:35 PM XXCoder: interesting
03:36 PM Eric__: I knew a woman that made her living that way, she had a storefront shop
03:38 PM XXCoder: amazing
03:42 PM XXCoder: lol cnc lathe https://youtu.be/CHFaflPIDX8
03:42 PM XXCoder: mostly 3d printed
03:44 PM XXCoder: whats cool is that guys resourceful
03:44 PM XXCoder: trying to make do with limited resources
04:00 PM internut: that's cool
04:01 PM internut: My first 3D printer project was a Pan-Tilt-Slide system for shooting time lapse videos with camera moves
04:01 PM internut: https://www.youtube.com/watch?v=9kqBcZl1I98
04:01 PM internut: I made one time-lapse and got busy with other stuff
04:01 PM internut: :/
04:02 PM internut: https://panicattackpictures.com/pan-tilt/index.html
04:02 PM XXCoder: lol that fili looks like ye olde timey video glitch
04:03 PM internut: haha
04:03 PM internut: I wrote a proggy to:
04:03 PM XXCoder: flsun prusa ripoff printer?
04:03 PM internut: move the camera
04:03 PM internut: print some
04:03 PM internut: make the 3D printer 'pose' for the next frame
04:03 PM internut: take a picture
04:03 PM internut: repeat
04:03 PM XXCoder: nice. I wanted to try that
04:04 PM internut: I had the slider
04:05 PM internut: it's a real piece of movie making gear
04:05 PM XXCoder: nice
04:05 PM XXCoder: evenually I will get prusa parts and fix prusa mk3
04:05 PM XXCoder: then learn how to use mmu2 oh boy
04:05 PM internut: what parts do you need?
04:06 PM XXCoder: heated bed wires and termostat for it
04:06 PM internut: I see
04:06 PM Eric__: In my day you had to cast your inadequate lathe out of soda cans and probably burn you foot off
04:06 PM XXCoder: last owner cat chewed on those
04:06 PM internut: Folgertech seems to be back in business
04:06 PM XXCoder: she was planning to move outside usa so she planned to throw em in trash anyway
04:06 PM internut: I see
04:06 PM XXCoder: I drove 1675 miles to salvage it
04:07 PM internut: https://folgertech.com/products/high-stability-ntc-thermistor-100k-with-wire-reprap-prusa-mendel-bed-or-hot-end-1?_pos=1&_sid=707dabff1&_ss=r
04:07 PM internut: I think that's your thermistor
04:07 PM internut: ($1.99)
04:09 PM XXCoder: nah its real prusa
04:09 PM internut: Aren't they pretty much the same?
04:10 PM XXCoder: possibly? but i wanted to keep it all offical prus parts
04:11 PM internut: I see
04:11 PM internut: it's more like a collectable
04:11 PM XXCoder: its still far cheaper than buying whole machine and $2000 worth of filiments
04:11 PM internut: well, my knockoff was $270
04:11 PM internut: :)
04:12 PM XXCoder: yeah. mine would cost $1000 or so, with mk3 and mmu2
04:12 PM internut: what's mmu2?
04:13 PM XXCoder: its 5 color filiment changer
04:13 PM XXCoder: https://shop.prusa3d.com/en/upgrades/183-original-prusa-i3-mk25s-mk3s-multi-material-2s-upgrade-kit-mmu2s.html#
04:13 PM internut: oh, well hell yeah
04:14 PM XXCoder: also has https://shop.prusa3d.com/img/cms/buffer.jpg
04:16 PM internut: nice
04:16 PM XXCoder: it apparently prevents tangles
04:17 PM XXCoder: makes sense since you need big space for 5
04:18 PM internut: I've made dozens of things with my printer
04:18 PM internut: I have brackets that two difference phones sit in, and the power cable is there for the phone to mate with
04:19 PM internut: they're on either side of my main working monitor
04:19 PM internut: stuff like that
04:19 PM internut: can't imagine how I got along without it
04:19 PM XXCoder: nice
04:20 PM XXCoder: i completed the cpap hose holder design
04:20 PM XXCoder: its so much better than hose just getting over bed head. no clicky feel when it moves over or back
04:20 PM internut: cool
04:21 PM internut: here ya go, I was at a friend's house playing with a puzzle
04:21 PM internut: so I went home and printed one
04:21 PM XXCoder: :)
04:22 PM internut: then I realized that with OpenSCAD, I could pretty easily make an animation of how the pieces fit together:
04:22 PM internut: https://www.youtube.com/watch?v=e9qaZdl_jjI
04:22 PM XXCoder: nice
04:22 PM XXCoder: oh i also ordered new bed for mini
04:22 PM XXCoder: orginial was already badly damaged by last owner due to careless (didnt level bed)
04:23 PM XXCoder: but now its halfway dead
04:23 PM internut: mini?
04:23 PM XXCoder: mp mini select v2
04:23 PM internut: oh, monoprice
04:23 PM XXCoder: bought that one for $77, shipped
04:23 PM internut: I too have difficulty resisting a deal
04:24 PM internut: :)
04:24 PM XXCoder: yeah I had few aging (4 year old) filaments I wanted to use up
04:24 PM XXCoder: and have fun while bored at home
04:24 PM internut: where's home?
04:26 PM XXCoder: tacoma, wa heh
04:26 PM zeeshan: howdy
04:26 PM zeeshan: happy friday
04:26 PM XXCoder: hey
04:26 PM internut: hello
04:26 PM internut: I'm between Denver and Boulder
04:34 PM XXCoder: cool :)
04:34 PM XXCoder: wow
04:34 PM XXCoder: https://youtu.be/OBB5WuhNhWk
04:34 PM XXCoder: a multicolor you can easily add
04:58 PM internut: I'd like to set up a bunch of Raspberry Pis with cameras and be able to do 3D portraiture
04:59 PM XXCoder: nice
05:01 PM internut: needs more cmyk
05:04 PM internut: at least, that would be the fantasy
05:05 PM XXCoder: mixer is bit diffult to do
05:05 PM internut: I can imagine
05:07 PM internut: oh, I've never seen such a system
05:07 PM internut: thanks for sharing
05:10 PM XXCoder: no problem
05:14 PM roycroft: it's the weekend!
05:14 PM roycroft: and it's going to be so exciting
05:14 PM roycroft: i get to work 6-8 hours tonight
05:14 PM roycroft: and then i get to work all day tomorrow
05:14 PM roycroft: but i'm taking at least monday off as comp time
05:15 PM Tom_L: they should get their weekdays aligned
05:17 PM roycroft: i'm moving some servers and there will be extended downtime
05:18 PM roycroft: i should do all of this in the middle of the night, but i'm not willing to do so
05:18 PM roycroft: so doing it during the evening and over the weekend is less disruptive than doing it during business hours, and is an acceptable compromise
05:19 PM internut: I've got a stack of 1U servers, 4 generations, long since powered off
05:20 PM internut: any ideas on how to get rid of them?
05:22 PM roycroft: i know what doesn't work
05:22 PM roycroft: putting them in the free section on cl
05:22 PM roycroft: i ended up donating mine to the local school district
05:23 PM roycroft: they can't use them, but they can send them to the state computer recycling center and get money for recycling them
05:23 PM roycroft: and i got a tax write-off
05:23 PM roycroft: so it was a win-win thing
05:23 PM internut: haha
05:24 PM internut: there ya go, I've got to find a way to donate them
05:24 PM roycroft: the recycling center is in hood river, a 3 hour drive from here
05:24 PM roycroft: if i wanted to recycle them directly i'd have to drive there, donate them, and not get any cash
05:25 PM roycroft: but the school district were able to put them in a pile and wait for the recycling center truck to show up and collect them
05:25 PM roycroft: the machines i got rid of were decent machines, but they were 32 bit, and had ide interfaces (although i had added some sata controllers to some of them)
05:26 PM roycroft: i had even put a fresh vmware esxi install on them
05:26 PM roycroft: figuring that someone would want them for a lab or whatever
05:26 PM roycroft: but even craigslist thought they were worthless
05:28 PM internut: I think the oldest of these systems could be Pentium III
05:29 PM roycroft: oh, mine were xeons
05:29 PM internut: It's got 3 - 9GB 10000 RPM SCSI drives in it
05:29 PM roycroft: most of them dual processor, and 8 cores
05:29 PM roycroft: but since they were 32 bit they maxed out at 4GB of ram
05:29 PM internut: I think it's dual socketed
05:30 PM roycroft: i actually have two of the machines in production still
05:30 PM roycroft: one is my pbx, and the other a backup server
05:30 PM roycroft: those last two will be going away soon
05:31 PM internut: a friend of mine worked for a company that had some rack space in a colo facility. I did a little security consulting for them, and they gave me 1U in their rack.
05:31 PM internut: so for years it was connected with a big fat pipe to the internet
05:31 PM roycroft: bugger
05:31 PM internut: at least for those days
05:31 PM roycroft: it's not supposed to rain tomorrow, and i'll be at work all day
05:31 PM internut: :)
05:31 PM roycroft: it's suppoed to rain on sunday again, when i'mhome
05:32 PM JT-Shop: you're just lucky
05:32 PM internut: what part of the world are you in?
05:32 PM roycroft: i really need to get some gardening done, and i'm not going to deal with that stuff in the rain
05:32 PM roycroft: i'm in western oregon
05:32 PM roycroft: it looksl like monday it won't rain, though, and i'm off work then
05:32 PM roycroft: so all is not lost
05:32 PM internut: it's hard to count on the weather
05:32 PM * roycroft needs to go warm up some tried & true varnish oil shortly
05:32 PM JT-Shop: I put some tomato seeds in the fermentation chiller turned to proofing box today
05:33 PM roycroft: nice
05:33 PM JT-Shop: how do you apply it?
05:33 PM roycroft: i just have to oil a knob today
05:33 PM roycroft: so i'll just dip it
05:33 PM roycroft: i use a rag for most stuff
05:33 PM JT-Shop: I used a foam brush to spread it out then a rag to wipe it off
05:33 PM roycroft: but small parts i dip
05:34 PM roycroft: what do you think of it so far?
05:34 PM JT-Shop: probably works better when warm
05:34 PM roycroft: there's no way it's fully cured yet, so you can't really know
05:34 PM roycroft: yes, i think i told you that :)
05:34 PM JT-Shop: I'm sold, I like it
05:34 PM internut: watch those oil soaked rags
05:34 PM roycroft: just be sure to wipe it until it's completely dry
05:35 PM roycroft: otherwise it will never cure
05:35 PM JT-Shop: harder wood seems to be slow to absorb it
05:35 PM roycroft: yes
05:35 PM roycroft: heating it helps
05:35 PM JT-Shop: I watch them in the wonder wood...
05:35 PM roycroft: not sanding it too fine helps
05:35 PM roycroft: p120 is fine
05:35 PM roycroft: maybe p180
05:35 PM roycroft: but never any finer than that
05:35 PM JT-Shop: workbench p80 I think
05:35 PM roycroft: that's what i use on my workbench
05:36 PM roycroft: it drives me nuts to see folks like dave stanton who sand to p800 or above and then apply oil
05:36 PM roycroft: all they've done is close up the pores so they won't absorb the oil
05:36 PM JT-Shop: yeah depends on the finish that is being applied
05:36 PM roycroft: and there's no point in sanding that high
05:36 PM roycroft: the oil will put a film finish on the wood
05:37 PM JT-Shop: I'll upload some photos during free time in the morning
05:37 PM roycroft: well if you sand that high it won't absorb oil or stain or most anything else
05:37 PM roycroft: if you want a raw wood finish, then go ahead and do that
05:37 PM JT-Shop: got all my holes drilled for the wagon vise finally
05:37 PM roycroft: nice
05:38 PM JT-Shop: used my magnetic drill press lol
05:38 PM roycroft: that's not as nice a screw as the ones from benchrafted, but it's a good screw
05:38 PM roycroft: and well worth what you paid for it :)
05:38 PM JT-Shop: the one on this workbench is just junk I had laying around and all thread
05:38 PM roycroft: right
05:39 PM roycroft: you're not going to use the new screw in its place?
05:39 PM JT-Shop: I might use it on the bigger bench built with syp
05:39 PM JT-Shop: this top is too thin... only about 1 1/4" thick
05:40 PM JT-Shop: went looking for 2 x 12 x 12 syp and the pickings were slim and expensive
05:42 PM JT-Shop: time to lock up and kick some chicken butts and head inside
05:43 PM roycroft: the glue pot is heating up
05:44 PM roycroft: so i'll go do my oil dip thing in a half hour or so
05:46 PM JT-Cave: do you dip and let it drip off?
05:49 PM roycroft: i dip it, hold it in for a minute or so, let it run off, and then wipe it
05:49 PM roycroft: i leave a little film on it when i first wipe it
05:49 PM roycroft: then a half hour later i go back and wipe it as dry as possible
05:50 PM roycroft: when i'm applying to a large surface i wipe it on fairly thickly, let it sit for a half hour, then wipe as dry as possible
05:55 PM JT-Cave: I gotta figure out wtf us using up my data... used 0.3GB today and only checked email a few times and looked a couple of pages
06:25 PM zeeshan: hey JT
06:26 PM zeeshan: have you ever built a pier foundation?
06:36 PM Tom_itx: hey z
07:12 PM Tom_itx is now known as Tom_L
07:51 PM zeeshan: hey tom
08:14 PM FinboySlick: For automotive wheel bearing. Sealed SKF or Naional unsealed?
08:16 PM Tom_itx: is it covered?
08:17 PM Tom_itx is now known as Tom_L
08:17 PM FinboySlick: Not sure.
08:17 PM Tom_L: haven't removed it yet?
08:18 PM FinboySlick: No, I'm shopping 'cause my local shop wasn't sure they could get the right kind. I'm not equipped to do that kind of work, and I'd have to do it in the snow.
08:19 PM Tom_L: is it a powered wheel or just an axle?
08:19 PM FinboySlick: They're all powered.
08:19 PM Tom_L: i'd be enclined to say sealed
08:19 PM FinboySlick: Me too.
08:19 PM Tom_L: inclined
08:19 PM FinboySlick: https://www.rockauto.com/en/moreinfo.php?pk=1839086&cc=1444313 is the skf
08:19 PM internut: I'm unclined
08:19 PM FinboySlick: https://www.rockauto.com/en/moreinfo.php?pk=219138&cc=1444313 is the national
08:20 PM Tom_L: they both look like they have some sort of seal
08:20 PM Tom_L: or at least a dust cover
08:21 PM Tom_L: is the bearing pressed on?
08:21 PM FinboySlick: I believe so.
08:21 PM Tom_L: if so good luck and god bless...
08:21 PM Tom_L: do you have a press?
08:21 PM enleth: FinboySlick: sealed, 2RS
08:22 PM FinboySlick: I'm not doing the work, I'm just shopping for my local mechanic.
08:22 PM enleth: wheel hubs get all sort of watery-salty-muddy shit into them, seals are needed to keep it out of bearings
08:22 PM FinboySlick: enleth: So SKF would be your pick?
08:22 PM Tom_L: Integral ABS encoder seal where applicable
08:22 PM Tom_L: says the national one
08:23 PM Tom_L: Premium seal design keeps out dirt and contaminants and retains lubrication in bearing
08:23 PM Tom_L: they both are sealed
08:24 PM Tom_L: you didn't read the fine print :)
08:25 PM FinboySlick: Alright. SKF is cheaper though.
10:26 PM veegee: anyone know where I can get coke (fuel)?
10:27 PM veegee: I should be able to reduce the lead dioxide to lead with it. I might be able to use charcoal instead, but not sure
10:28 PM roycroft: you get lumps of coal, put them in your forge, and make coke out of them
10:32 PM roycroft: amd o
10:32 PM roycroft: er, and i'm not being snarky
10:33 PM roycroft: i've never seen nor heard of refined coke for sale
10:33 PM roycroft: every blacksmith gets coal and converts it to coke in the forge
10:34 PM veegee: roycroft ah ok, makes sense. I thought you needed an airless kiln or something to make coke
10:35 PM roycroft: no, not at all
10:35 PM roycroft: it's the forging proces
10:35 PM roycroft: you start a coal fire
10:35 PM veegee: roycroft also, would charcoal work?
10:35 PM roycroft: the coal converts to coke and releases clinkers (impurities)
10:35 PM roycroft: the smith removes the clinkers and then feeds more coal in from the outside of the fire
10:35 PM roycroft: i think charcoal would work
10:35 PM roycroft: but i'm not sure
10:36 PM roycroft: you can't just put them in a grill though - you need a forge
10:36 PM roycroft: it requires lots of oxygen to make coke
10:36 PM roycroft: so a grill with a blower
10:36 PM veegee: yeah that's doable, I intend to make a forge with firebrick
10:36 PM veegee: yeah that's the plan
10:37 PM veegee: The only reason I'm doing this is to recover the other half of the mass of the lead acid battery as pure lead to cast as counterweight
10:38 PM veegee: density is important because I still need space for the LiFePO4 batteries in the forklift
10:38 PM veegee: I have to see if it's even worth smelting the lead dioxide. If the density of the lead dioxide paste is close to pure lead, there may be no need and I can simply seal it in a sheet metal container and use it as-is
10:39 PM roycroft: why not just mine some gold and us that?
10:39 PM roycroft: gold is almost twice as dense as lead
10:39 PM roycroft: you could save a lot more space that way
10:40 PM veegee: wikipedia says 9.38 g/cm^2 for lead dioxide and 11.34 g/cm^2 for lead so may not need to purify it
10:40 PM roycroft: and gold is about 20g/cm^2
10:40 PM veegee: I already have 5,000 lbs of lead in some form that just needs purification
10:40 PM veegee: and as you already know, biggest reason is cost
10:40 PM XXCoder: gold is expensive
10:40 PM XXCoder: tungsein is roughly same density
10:41 PM roycroft: yeah, but veegee is rich and has lots of free time
10:41 PM unterhaus: I got some flat lead ribbon with my lathe. Glad I didn't figure out how to throw it out
10:41 PM veegee: I'm not rich
10:41 PM roycroft: he can head off to the yukon and mine for a while
10:41 PM unterhaus: use it for damping vibration on long things
10:41 PM veegee: lead is actually pretty expensive too
10:41 PM veegee: significantly more than iron
10:41 PM roycroft: we're past peak metal for most useful metals
10:42 PM unterhaus: gubmint discourages uses of lead
10:42 PM XXCoder: we need space mining
10:42 PM roycroft: peak metal being defined as when it's more expensive to mine for new metal than to recycle existing metal
10:42 PM XXCoder: lead is quite bad for envorment
10:42 PM XXCoder: id avoid using it at all
10:42 PM unterhaus: it's bad for people
10:42 PM XXCoder: and enorment yes
10:42 PM roycroft: mercury is more dense than lead
10:43 PM roycroft: and even more harmful to the environment
10:43 PM unterhaus: I guess there is nothing like lead if that's what you really need
10:43 PM roycroft: it would not be good forklift ballast anyway
10:43 PM roycroft: it woudl slosh around to much
10:43 PM veegee: XXCoder lead is one of the most successfully recycled metals ever
10:43 PM unterhaus: bismuth
10:43 PM XXCoder: vee indeed
10:43 PM roycroft: although veegee does live in the great white north, so perhaps that would not be so much of a problem there
10:43 PM XXCoder: bismuth isnt tht quite expensive too?
10:44 PM XXCoder: not as bad as tungsein or lol gold
10:44 PM veegee: judging by the price of pepto bismol, yes, very
10:44 PM unterhaus: if we could just figure out how to make very dense plastics out of recycling
10:45 PM XXCoder: i wonder if you can make ballast from dead tungsein carbide tools
10:45 PM XXCoder: with some matrix to make it stay together
10:45 PM veegee: we're talking 2,500 lbs here
10:45 PM roycroft: uranium is about the same density as gold, and much less expensive
10:45 PM roycroft: so there's another option
10:46 PM XXCoder: its hard to even get depelated uranium
10:46 PM veegee: and it's still more than 100x the cost of lead
10:47 PM roycroft: the tungsten idea might be a good one
10:47 PM XXCoder: lol yea doubt it;d be anywhere near as affordable as lead
10:47 PM roycroft: since that's also in the same density range as gold and uranium
10:47 PM XXCoder: i forgot if its heavier or lighter than gold
10:47 PM roycroft: well you might find some waste tungsten
10:47 PM XXCoder: i think its slightly lighter
10:47 PM roycroft: i mean
10:48 PM roycroft: now that we don't use incandescent light bulbs any more, there must be a whole lot of old filaments lying about to harvest
10:48 PM Tom_L: tungsten was bought up by the govt to make large experimental spears
10:48 PM XXCoder: kenetic weapons or just making funny?
10:48 PM Tom_L: kinetic weapons
10:48 PM roycroft: as in britney spears?
10:49 PM veegee: obviously hasn't happened yet
10:49 PM veegee: or someone would have seen ti

10:50 PM roycroft: so i just finished one of the imporant tasks that had to do off-hours tonight - moving my boss' ad server that he uses to generate huge wads of cash
10:50 PM roycroft: i installed that server for him four years ago
10:50 PM roycroft: before i moved it i checked the stats
10:50 PM Tom_L: so they bought up tons of it
10:50 PM roycroft: it has had exactly 283 page impressions since in installed it, the last page impression in july of last year
10:50 PM roycroft: it's had exactly one ad click, in march of last year
10:51 PM roycroft: so yeah, it's super important that i not move it during business hours
10:51 PM * roycroft moves on to the next mission-critical task that must be done off-hours
10:58 PM veegee: https://www.lenntech.com/periodic-chart-elements/density.htm WHAT
10:58 PM veegee: there are elements for which we do not know the density!?
10:58 PM veegee: not just one or two, many!
11:01 PM roycroft: some elements have never existed for more than a second
11:06 PM rue_mohr: anyone ever put a high resolution encoder on a stepper and measured the step response?
11:10 PM XXCoder: Tom_L: interesting
11:13 PM XXCoder: roycroft: yeah you need enough of it to measure
11:14 PM XXCoder: heaviest ones we made only few atoms, and we dont know how it would interact because weight of atoms dont correspond with density
11:14 PM XXCoder: ah so tungsein is *slightly* more dense
11:16 PM XXCoder: theres also odd pair of metals that is very hard to seriously seperate, so purity at best is 97%
11:16 PM XXCoder: so density might be slightly off on those
11:37 PM roycroft: density is predictable, but needs to be measured
11:37 PM roycroft: we don't know everything about how the unverse works yet
11:37 PM XXCoder: yeah but it is NOT predictable based on atomic number
11:37 PM roycroft: no
11:37 PM XXCoder: meaning if you dont have enough to measure it, it remains unknown
11:38 PM roycroft: but physicists can predict fairly closely what the density of an element is
11:38 PM XXCoder: element 118 for example, we only ever made few atoms that lasts minutes
11:38 PM roycroft: i'm not a physicist, and don't know nearly enough to know how they do it
11:38 PM XXCoder: hmm maybe
11:39 PM roycroft: i'm not saying the get it spot on
11:39 PM roycroft: but they can make pretty good guesses
