02:14 AM Deejay: moin
02:27 AM veegee: Every air mattress I've ever used doesn't last longer than a few months when used daily
02:27 AM veegee: Am I just too rough or are they not meant for long term use like that?
02:27 AM XXCoder: too much horzional tango?
02:27 AM veegee: I forgot, which one is that one?
02:27 AM veegee: oh right
02:27 AM XXCoder: :D
02:27 AM veegee: unfortunately no, not right now. I barely have time for the things I want to do
02:27 AM veegee: Ended things with a girl recently, don't have time for her nonsense
02:27 AM XXCoder: that sucks
02:27 AM XXCoder: sorry about that joke
02:27 AM veegee: Ain't no thang dawg
02:30 AM veegee: how is that possible?
02:30 AM veegee: They can handle a lot of weight
02:30 AM XXCoder: im at 308 pounds
02:31 AM XXCoder: sure but then theres stress points and if I move around those gets hit
02:32 AM veegee: ah I hear ya
02:33 AM veegee: I have broad shoulders, and that tends to put more pressure on the joint too
02:33 AM veegee: Had a shoulder joint surgery a few y ears ago which makes it worse
02:33 AM XXCoder: in your cse its possible that its friction and sych. do you just put it on hard surface or put it on blank under?
02:33 AM XXCoder: blanket
02:35 AM veegee: hard surface
02:35 AM veegee: never thought to put it on something, I'll try it
02:35 AM XXCoder: it would spread it a little. careful to avoid folds
02:36 AM XXCoder: spread stresses that is
05:02 AM JT-Cave: mornin
05:04 AM XXCoder: yo
05:07 AM Tom_L: morning
05:21 AM JT-Cave: damn I got to get a bunch of huge red oak quarters off my trailer this morning so I can take the fence to Manila
05:23 AM Tom_L: did you get that big log all sawed up?
05:23 AM JT-Cave: yea
05:24 AM XXCoder: nice
05:26 AM JT-Cave: https://gnipsel.com/images/wood-working/red-oak/red-oak-03.jpg
05:26 AM JT-Cave: https://gnipsel.com/images/wood-working/red-oak/sawmill-01.jpg
05:27 AM JT-Cave: https://gnipsel.com/images/wood-working/red-oak/
05:28 AM JT-Cave: got some smaller white oak up to cut into boards now
05:32 AM Tom_L: nice pile of wood there
05:34 AM XXCoder: plan to make billets or something out of wood chips?
05:34 AM XXCoder: woodgear made very nice automated system
05:35 AM XXCoder: probably misremembered name, very tired lol
05:36 AM JT-Cave: I use the noodles for mulch and use the sawdust in my compost bins
05:39 AM XXCoder: cxant find it
05:40 AM XXCoder: basically it uses cycling machine to break logs to compact chips into metal curved tube to make those chips rods you use to burn
05:41 AM JT-Cave: wood pellets?
05:43 AM XXCoder: yeah
05:43 AM Tom_L: kid went back to 10 hr days
05:44 AM Tom_L: still only 40 hrs though
05:44 AM Tom_L: they were doing 32
05:45 AM XXCoder: thats good
05:46 AM Tom_L: hope you find something
05:46 AM Tom_L: the other one seems to like the new place
05:48 AM XXCoder: hope so. i recently had my "vacation. got back today
05:48 AM XXCoder: total over 10 hours driving across 2 days lol
05:49 AM XXCoder: went to bunch of places
05:52 AM Tom_L: nice
05:53 AM XXCoder: yeah somewhat mixed success but hapy with it anyway
05:53 AM XXCoder: for example my first "mission" was to neah, wa. i wanted to go to literal tip of wa state
05:53 AM XXCoder: neah was closed to outsiders due to covid
05:53 AM Tom_L: not the best time to be travelling
05:54 AM XXCoder: i decided to just stay at nearest side of road for stargazing (the reason for trip)
05:54 AM XXCoder: i enjoyed it for few hours before fog come in then moon rose
05:54 AM XXCoder: well worth it, as I also had bunch of stops to enjoy inlet sea scenes
05:55 AM XXCoder: i hoped for level 1 sky but got between 3 and 4. lots stars but no milky way. https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTkxMTE4Ni9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNzIxMTQ1Mn0.pbbuc0wUreurU82NLtcHHks1z_lExOiFH1SxLdp90BQ/img.jpg?width=980
05:56 AM XXCoder: anyway i slept in my car there then drove 3 hours to beach, stayed there for while, then 2 hours to home lol
05:56 AM XXCoder: (tues one was 5 hours one way from home to near neah)
06:12 AM XXCoder: Tom_L: yes I agree, but pretty much 90% of my trip i am alone
06:12 AM XXCoder: few time i am along other people i wear a mask
06:12 AM XXCoder: wa state, west side is quite good on wearing masks
08:45 AM roycroft: wow
08:45 AM roycroft: it is actually raining lightly
08:46 AM roycroft: this is awesome
08:46 AM roycroft: as long as it stops by early afternoon, which it should
08:57 AM unterhaus_: somebody has a kickstarter for a 3d printed continuous carbon fiber bicycle
08:57 AM unterhaus_: prices quoted are in line with carbon fiber bikes. Trying to decide if it's a scam or not
08:58 AM unterhaus_: not that I would buy one, but that seems like evidence of a breakthrough. The 3d carbon fiber companies don't seem to be showing parts anything like that
09:43 AM roycroft: while the rain is light, it's steady, and it's been ongoing for quite some time
09:43 AM roycroft: today is not a good day to drive anywhere
09:44 AM roycroft: after two months of hot weather and zero precipitation the roads will be oily, and drivers will be idiots and think that driving in wet conditions is the same as driving in dry conditions
09:46 AM Loetmichel: *BAH* just made 144 little alu angles from stock extrusion on the table saw... Conclusion: sweating like a waterfall and close to red hot alu swarf: BAD combination... $me looks like a silvery snowman atm AGAIN... and that stuff itches when its glued to your skin with sweat and salt. :-(
11:46 AM jymmmm: Loetmichel: That's what http://BIGASSFAN.COM/ is for =)
11:47 AM Rab: Sounds like a solution for evenly distributing aluminum glitter all over the shop.
11:48 AM Rab: Maybe some kind of vacuum attachment for the table saw could help.
11:49 AM jymmmm: or just putting the guard back on the tablesaw =)
11:50 AM jymmmm: Rab: The Glitter Shop, good name =)
11:52 AM Rab: I use a chop saw for aluminum stock (no comment on safety). It has a guard and a collection bag, but it still makes a huge mess.
11:54 AM Rab: Kennametal closing US manufacturing, apparently.
11:57 AM roycroft: is their johnson city plant the only one left in the us?
11:57 AM Rab: That I cannot say.
11:57 AM roycroft: their announcement is that they're closing that plant
11:58 AM roycroft: i haven't seen anything that indicates they're shutting down anything else in the us
11:58 AM roycroft: but if that's the only one left in this country, then what you said is accurate
11:59 AM robotustra: Rab, yep, chips collection is my problem now :)
11:59 AM roycroft: it would not surprise me - this president has done nothing to retain jobs in this country, and has only driven up the cost of manufacturing with his imposition of tarrifs on rea materials that are not being produced here
11:59 AM Rab: The PM commentariat described them as ceasing US manufacturing entirely, but nobody's mentioned specifics.
12:00 PM roycroft: raw
12:01 PM * roycroft had best shut up now
12:01 PM roycroft: sorry
12:02 PM jymmmm: Rab: I use my tablesaw for cutting aluminum, makes a PERFECT finish, though chips do get into hair and such
12:02 PM roycroft: i occasionally cut aluminium with my table saw, but i absolutely hate doing it
12:02 PM robotustra: heh
12:02 PM roycroft: even more than the mess, the noise is just horrific
12:03 PM robotustra: aluminum chips are flying everywhere
12:03 PM roycroft: no matter how good the hearing protection, it's a horrible noise
12:03 PM Rab: This is the article under discussion on PM: https://www.impomag.com/home/news/21142193/kennametal-closing-tn-plant-combines-business-segments-as-sales-sink
12:04 PM Rab: It's about the Johnson City plant closing, and says "operations will be consolidated into other newly modernized facilities", but doesn't say where.
12:05 PM roycroft: right
12:05 PM roycroft: i'm not seeing anywhere in that article that all us manufacturing will cease
12:05 PM roycroft: just that the johnson city plant will close
12:06 PM roycroft: the question is: where are the 'other newly modernized facilities' located?
12:12 PM robotustra: Rab, don't you find that the link you have posted has mostely negative news?
12:12 PM robotustra: or it's intentionally dedicated to negative news?
12:13 PM Rab: robotustra, specific to Kennametal, or...?
12:13 PM robotustra: all links below
12:14 PM Rab: I didn't even notice...I expect that low-grade clickbait crud from every news organization, now.
12:15 PM Rab: But I admit I did not review IMPO's other output to see if they had a slant to their news.
12:16 PM robotustra: usually I devide news on bad news and good news
12:16 PM robotustra: this one have dominance of "bad"
12:19 PM Rab: I do question the relevance to industry of some of this content. https://www.impomag.com/home/news/21142516/businessman-killed-at-machine-testing-lab
01:22 PM CaptHindsight: hah, Priority sent from CA to Chicago, has been through El Paso and now Albany, NY, wonder where it will go next?
01:23 PM CaptHindsight: in addition to cutting overtime are they also misdirecting mil to criss cross the USA?
01:23 PM CaptHindsight: mil/mail
01:45 PM roycroft: that's been happening with the usps for a long long time
01:46 PM roycroft: i've had parcels go from san francisco to portland to seattle to new york to portland to reno to roseburg (south of here in oregon) to eugene
01:46 PM roycroft: and similar weird routes
01:47 PM roycroft: the overtime thing is really bothersome though
01:47 PM roycroft: i currently have a parcel that was due on monday, arrived at my local post office tuesday, and has been sitting there every since
01:47 PM roycroft: it is not out for delivery again today
01:49 PM Tom_L: CaptHindsight, it's fluttering around like a stray bottle rocket on the 4th of July
01:52 PM Rab: Maybe they're using rail transit as a storage buffer. And/or maybe it's some highly advanced capacity optimization at the expense of transit time.
02:03 PM CaptHindsight: roycroft: my local post office will let me pickup if they have it, they even called the postal worked in the truck once to verify the block/street they were on so I could meet them
02:03 PM CaptHindsight: Rab: sounds like round robin
02:19 PM roycroft: i try to avoid my local post office
02:19 PM roycroft: half the people who go there don't wear masks
02:21 PM roycroft: i used to have everything delivered there, and i'd go there to get mail daily
02:21 PM roycroft: but since the pandemic and the poor behavior of the patrons there i've shifted almost everything to home delivery
02:38 PM roycroft: does anyone here have a link to a good, trusted site for sizing linear motion rail systems?
02:38 PM roycroft: i'm not looking for search engine results
02:38 PM roycroft: i'm looking for something that is known to be reliable
02:54 PM Tom_L: but search engine results get you started on your way
02:56 PM Tom_L: so i can't post this good link
02:57 PM roycroft: i've found several links that appear to be "good', but have differing information
02:58 PM roycroft: the issue is that i'd like to design a small sliding table that will carry a fair amount of weight, but i need to keep the table and its components as small as possible
02:58 PM roycroft: so overbuilding to be sure it's strong enough is not what i want to do
02:58 PM roycroft: it's never what i want to do, but sometimes it's acceptable
03:00 PM Tom_L: pcblinear gives data sheets for it's slides
03:03 PM Tom_L: thompson has a selector guide
03:08 PM roycroft: hmm
03:08 PM roycroft: i'm familiar with thompson
03:09 PM roycroft: i'm thinking of using v-groove bearings, though, and they don't make those
03:09 PM roycroft: i'll check out pcblinear
03:09 PM roycroft: they have v-groove bearings, so great
03:10 PM roycroft: this application will be on a woodworking machine, and it will be subject to a fair amount of dust
03:10 PM roycroft: my thinking is that v-groove bearings would probably hold up best in those conditions
03:16 PM Deejay: gn8
03:16 PM jymmmm: Deejay: gn9
03:16 PM Tom_L: vxb has v-groove bearings but i dunno the quality
03:18 PM jymmmm: tiny ones last I looked
03:18 PM jymmmm: but that was a while ago.
03:23 PM roycroft: i'm still not sure what size i need
03:25 PM roycroft: vbx are cheap in quantity
03:29 PM roycroft: the rain has stopped, and the sun is trying to poke out
03:29 PM roycroft: nice - i'm off work in an hour and a half and i have a lot of milling to do today
03:30 PM roycroft: i'll be milling my workbench components to final dimension today, and hopefully will be able to start laminating the legs tomorrow, and the bench top pieces over the weekend
03:31 PM roycroft: once the milling is done i should not have to work in my driveway any more save for one pass of the bench top pieces through the thicknesser when they are fully glued up
04:27 PM Loetmichel: jymmmm / Rab: http://www.cyrom.org/palbum/main.php?g2_itemId=17930&g2_imageViewsIndex=1
04:27 PM Loetmichel: it HAS a vacuum attachment
04:28 PM Loetmichel: doesent help that much with a 216mm sawblade spinning at 5500RPM ;)
04:28 PM Loetmichel: and cutting alu
04:28 PM Loetmichel: and loads of it
04:33 PM miss0r: CaptHindsight: It seems you've been trying to reach me at some point?
04:35 PM miss0r: And now I will head off to a much needed shower. I just did alot of work on the land rover camper project: https://imgur.com/a/BmETccJ
04:35 PM miss0r: See you around
04:38 PM CaptHindsight: miss0r: was likely a vehicle status update
04:39 PM miss0r: ahh. Well, there you have it
04:39 PM miss0r: :)
04:39 PM miss0r: also; if you ever feel like plating the inside of a 40+ year old land rover with sheet alu.. don't
04:39 PM CaptHindsight: I'm a few costs in to a 12+ coat paint job
04:40 PM CaptHindsight: costs/coats and yeah it costs plenty
04:40 PM miss0r: Unless you have a magic machine capable of replicating all the "organic" shapes such a car gets over time
04:40 PM miss0r: wow
04:40 PM miss0r: that is alot
04:40 PM jymmmm: Loetmichel: That's why I said put the guard back on =)
04:40 PM miss0r: does the car need to gain a few pounds to get road legal or something? :P
04:41 PM CaptHindsight: miss0r: i wanted to rebuild one of those ~20 years ago but could not find one here
04:41 PM CaptHindsight: an all aluminum body rover
04:42 PM miss0r: its overrated.. As none of the rovers are "all" aluminum
04:42 PM CaptHindsight: I likely would have graphic anodized the exterior
04:42 PM miss0r: Theres the odd, and mostly well hidden joint between steel and alu that kills everything
04:43 PM miss0r: sounds like a realy crazy idea :D
04:43 PM miss0r: but cool if you could've pulled it off.
04:43 PM miss0r: I'm just thinking of how much I need to use the Alu attitude reajustment hammer to make stuff fit
04:43 PM CaptHindsight: https://i.imgur.com/3pLawzP.jpg
04:44 PM CaptHindsight: i would need a hot tank the size of a small swimming pool for sealing
04:44 PM miss0r: I'm not saying you can't do the anodizing.. :) I'm more worried about the fitment of the plates & getting stuff to line up with graphics on it
04:45 PM CaptHindsight: anodize, but not seal, add graphics, dip entire car into sealing tank
04:46 PM miss0r: haha
04:46 PM miss0r: sure, that might work :D I can see no issues with that
04:48 PM miss0r: anyway. I am blacker than the blackest black right now. I will grap a quick shower and hit the hay. See you around
04:48 PM XXCoder: later
04:48 PM CaptHindsight: miss0r: seen fragalot lately?
04:48 PM CaptHindsight: say howdy if you do
04:48 PM miss0r: CaptHindsight: Not in person. We do keep in touch, though
04:49 PM miss0r: He became a father some months back, so I think he is kept busy
04:49 PM CaptHindsight: that will do it
04:49 PM miss0r: Indeed. I will tell him you said hi, when I speak to him next.
04:50 PM * miss0r is off
04:52 PM jymmmm: ve7it: Yo
04:53 PM jymmmm: ve7it: https://www.youtube.com/watch?v=EgF6-JbGUXA&vl=en
04:53 PM jymmmm: miss0r: is off his rocker
05:03 PM CaptHindsight: with audio, Hot Springs https://imgur.com/gallery/Bia0WiB
05:32 PM ve7it: jymmmm, yo
07:27 PM jymmmm: ve7it: 10MHz ref, whatcha think?
07:27 PM ve7it: can be very useful
07:28 PM * infornography enters with karate chop motions
07:28 PM * XXCoder falls over dead
07:29 PM ve7it: jymmmm, http://ve7it.cowlug.org/gpsreference.html I built one many years ago... was fun to check freq counters
07:36 PM jymmmm: ve7it: Yeah, I remember, thught you might like that lil one =)
07:43 PM ve7it: yeas... the little one with adjustable output is cool... could be put inside a ham rig and programmed to replace the reference oscillator... I cant remember .. I think my old Icoms hf rigs used 28 or 32Mhz
07:49 PM roycroft: well bummer
07:49 PM roycroft: it started sprinkling again
07:50 PM roycroft: the forecast failed me
07:50 PM Tom_L: i need a tool holder
07:50 PM Tom_L: but the test did prove it's doable
07:51 PM roycroft: i aborted the milling operation on the chance that the sprinkles might turn into something real, but i don't think they will
07:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/Broach/Test_Keyway3.jpg
07:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/Broach/Test_Keyway6.jpg
07:51 PM roycroft: i should have erected an ez-up
07:51 PM Tom_L: ghetto but it was proof of concept
07:51 PM Tom_L: just scrap cutoff i had under the lathe
07:52 PM roycroft: proof of a web page hanging and not fully loading here, unfortunately
07:55 PM roycroft: i found some more checking in some of the bench top pieces, so since i could not finish milling them today i am filling the checks with epoxy
07:55 PM * roycroft always tries to make lemonade somehow
07:56 PM Tom_L: mmm i'll restart the router
07:56 PM Rab: Hah: http://masterlist.co/
07:56 PM roycroft: both links hang
07:57 PM Tom_L: mine or his?
07:57 PM roycroft: yours
07:57 PM Tom_L: well they would
07:57 PM Tom_L: coming from the same server
08:05 PM roycroft: i've seen folks make a tool to fit in a boring bar to do that
08:06 PM roycroft: probably a carbide boring bar would be bes
08:06 PM roycroft: t
08:06 PM Tom_L: for a lathe yeah. that wouldn't work here
08:07 PM Tom_L: i'll whittle out a small holder one of these days
08:07 PM Tom_L: no hurry, it's planning ahead for my next spindle motor
08:08 PM Tom_L: it's got a 5mm key
08:29 PM CaptHindsight: wuz wonderrininin how they actuated these https://youtu.be/nIHpqqgybss?t=463
08:29 PM CaptHindsight: by bendin the elbow
08:30 PM CaptHindsight: https://www.teamunlimbited.org/arms
08:54 PM jymmmm: CaptHindsight: strings?
08:56 PM Tom_L: jymmmm, no strings attached! honest
08:58 PM jymmmm: I saw a metal rod at the elbow
09:03 PM Tom_L: maybe for the thumb movement?
09:25 PM CaptHindsight: i had to watch the video to see how they operated
09:26 PM CaptHindsight: their website skipped over that part and just focuses on the look
09:28 PM CaptHindsight: looking at a terminator version that has attachments: sucker punch, finger rockets, bread knife, spatula/shovel, spoon and fork
09:29 PM Tom_L: edward scissorhands
09:29 PM CaptHindsight: what kids want
09:30 PM CaptHindsight: hammer
09:30 PM CaptHindsight: grappling hook and winch
09:31 PM CaptHindsight: silly string/spider web sprayer
09:31 PM jymmmm: harpoon gun attchement
09:31 PM CaptHindsight: fishing line and reel
09:31 PM jymmmm: grenade launcher
09:31 PM CaptHindsight: bazooka
09:32 PM CaptHindsight: laser
09:32 PM CaptHindsight: flame thrower
09:33 PM CaptHindsight: CNC machine the arm, just print the parts that wear
09:33 PM CaptHindsight: knotty pine
09:34 PM CaptHindsight: white oak
09:34 PM CaptHindsight: Honduran mahogany
09:35 PM CaptHindsight: 3ft boom, selfie stick and gripper would be handy
09:36 PM CaptHindsight: https://i5.walmartimages.com/asr/66a03624-8c56-4011-b428-4f45a4fc2da6.669a50733bb24a97442885b7e8b501bd.jpeg
09:38 PM CaptHindsight: https://fandfind.com/wp-content/uploads/2019/10/358151-400x400.jpg
09:48 PM CaptHindsight: also interchangeable with any Ryobi cordless tool
11:00 PM t4nk_freenode: also handy for when your dog goes beside himself when you're on a walk.
11:10 PM unterhaus: penn state sends an email to employees, it's full of links. when you follow a link to a story, there is a link to the story
11:10 PM unterhaus: don't quite get it why they have that intermediate page
11:11 PM roycroft: so they can track you
11:14 PM unterhaus: interesting thought, but seems pointless
11:30 PM CaptHindsight: was just checking into the regulations for prosthetic devices
11:31 PM CaptHindsight: some states require a 6 year training program to fabricate them
11:34 PM unterhaus: that's outrageous
11:35 PM unterhaus: which states?
11:39 PM CaptHindsight: Illinois for one
11:39 PM CaptHindsight: looks like the coastal states
11:40 PM CaptHindsight: https://www.oandp.org/page/licalternatives
11:41 PM CaptHindsight: some don't require a license but requires certification through some pharmacy board
11:44 PM CaptHindsight: unterhaus: https://www.abcop.org/State-Licensure/Pages/state-licensure.aspx
