04:42 AM veegee: Damn I love the air line lubricator
04:48 AM veegee: After the hose is primed, keeps the air motors running super smooth constantly
04:48 AM veegee: Also a great way to oil coat big metal things with a blow gun
05:15 AM JT-Cave: morning
05:15 AM XXCoder: hey
05:59 AM pink_vampire: hi
05:59 AM XXCoder: yo
06:37 AM Tom_L: morning
06:38 AM XXCoder: hiya
06:38 AM Tom_L: veegee, a body shop would hate you for that
07:05 AM JT-Cave: yo
08:32 AM andypugh: So, who can guess what this is for? https://photos.app.goo.gl/bVKfPZMSHhciCpkW7
08:37 AM _unreal_: for cnc or for a car?
08:42 AM JT-Cave: looks like some kind of pigtail on a plug
08:43 AM andypugh: The “fishspine beads” are high temperature insulation. It is actually to take power from a PID temperature controller to an electric furnace.
08:48 AM JT-Cave: ah makes sense now
08:49 AM pink_vampire: I did a little experiment about removing zinc coating from nuts, and citric acid can do it, but I don't have any, so I dunk them in orange juice for about a day, and this is the results https://i.imgur.com/pQBjNIS.png
08:50 AM JT-Cave: yum zinc flavored orange juice
08:50 AM _unreal_: you could always get lime/lemon juice
08:50 AM JT-Cave: in the ninth ward of New Orleans you wash dishes in the zink
08:50 AM pink_vampire: then I did bluing and I just got it PERFECT https://i.imgur.com/Uw0xmBt.png
08:51 AM JT-Cave: andypugh, are you building a furnace for heat treating?
08:57 AM andypugh: JT-Cave: No, this one is for melting metal
08:58 AM andypugh: I already have a tube furnace for heat treating
08:58 AM andypugh: https://photos.app.goo.gl/3gRzrimZ9jik7mGk6
08:58 AM andypugh: Is the new one.
08:59 AM andypugh: This is the heat-treating one: http://bodgesoc.blogspot.com/2014/11/heat-treatment-furnace.html
09:09 AM _unreal_: shock and aww the numbers were reported WAYYY wrong https://www.sun-sentinel.com/coronavirus/fl-ne-coronavirus-florida-children-rate-20200725-woaowotttrbdxc4cqqshttqkje-story.html
09:17 AM Tom_L: andypugh, i used electrical motor insulation but my temps weren't near as high
09:18 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/toaster_oven/control_mounted1.jpg
09:18 AM Tom_L: the white braid
09:18 AM JT-Cave: nice heat treat oven
09:18 AM Tom_L: solder reflow
09:22 AM _unreal_: atmel controller?
09:25 AM Tom_L: yes
09:30 AM _unreal_: I'm still drawing my new z adapters noticed some missing features I need
09:30 AM _unreal_: like limit switches etc...
09:30 AM _unreal_: solved where to put the lower and the upper I believe at this point
09:31 AM _unreal_: the only hard part is deciding on how I'm going to deal with my Z stepper
09:31 AM _unreal_: I also likely need to upgrade it to a stronger motor. then again who knows maybe it will be just fine
10:21 AM andypugh: The Mexico coronavirus deaths have now exceded their murder rate. Which probably says more about the murder rate than their healthcare system.
10:31 AM andypugh: Firnace seems to work: https://photos.app.goo.gl/hdWT7iGxasGYiVov8
10:32 AM JavaBean: looks like it gets a bit warm, maybe needs better cooling?
10:34 AM Tom_L: yeah add some oxy
10:34 AM Tom_L: looks like it turned out nice andy
10:34 AM JavaBean: ^
10:35 AM Tom_L: also looks like you're about out of electrical outlets
10:36 AM andypugh: Those are mainly plugged in to hand tools, which are on the shelf to the right.
10:36 AM Tom_L: you can always add a few extensions :)
10:38 AM Tom_L: https://falconerelectronics.com/wp-content/uploads/2017/09/overloaded-outlet-strip-scaled.jpg
10:38 AM andypugh: There are 12 x 13A domestic sockets and 3 x 32A Commando sockets in that 8’ x 16’ garage.
10:39 AM Tom_L: should be plenty
10:48 AM JT-Cave: https://gnipsel.com/images/casting/Burner%20Test%2003.jpg
10:48 AM JT-Cave: that's my melting furnace, I have an oil nozzle but have not built a furnace that can take that kind of heat yet
10:52 AM andypugh: I might make a gas furnace some day, but I don’t know where I would be able to run it.
10:53 AM andypugh: I saw an electrical one on that YouTube and decided to make a similar design, just for fun.
10:53 AM Tom_L: what did you use for elements?
10:53 AM Tom_L: just nichrom wire?
10:54 AM JT-Cave: there's a paper online to calculate the element
10:55 AM andypugh: I copied this one, vaguely: https://youtu.be/Cte_LSYflAE
10:55 AM JT-Cave: I run that one outside especially when making lead cannon balls
10:55 AM Tom_L: my local electronics supply used to have all sorts of nichrom wire but i think he died and closed the shop
10:55 AM JT-Cave: weird set of tongs for the crucible
10:57 AM andypugh: I have a spool of nichrome wire, but it turns out you can buy loose elements from eBay, pre-made and rated: https://www.ebay.co.uk/itm/382627938613
10:57 AM andypugh: And they are really cheap.
10:57 AM Tom_L: yeah
11:24 AM * SpeedEvil wishes SiC elements were cheaper
11:31 AM JavaBean: JT-Cave, got a good/cheap supplier for lead?
11:31 AM Tom_L: car batteries
11:32 AM JT-Cave: just a bunch of old lead collected over the years
11:32 AM Tom_L: i used to bring home cutoff from lead ballast we'd machine for wing edges
11:32 AM JT-Cave: reminds me of the lead bricks they used at the shipyard to block off hot spots on the sub
11:33 AM Tom_L: and when i was at the screw machine shop, they moved a bunch of machines and i grabbed some of the lead they leaded the machines in with
11:33 AM Tom_L: they didn't reuse it
11:34 AM Tom_L: i made a 70lb well driver with some of it
11:35 AM JavaBean: currently at a 60# chunk for 109$ shipped, was hoping you knew a cheaper way
11:35 AM Tom_L: our resources aren't the same as yours
11:37 AM JavaBean: i noticed
11:41 AM Tom_L: probably not so much nowdays but scrap yards might have old lead plumbing
11:42 AM Tom_L: how much do you need?
11:44 AM Loetmichel: *hehe* just had a 747 fly over my roof while out on the balcony smoking... MAN either that pilot was indecided a lot or the plane had a problem. could hear the engines spool up and down in quick succession about 10 times... may have been only one of them though, sounded a bit "not in unison" if you know what i mean. *the interesting part of living close to a big airport*
11:44 AM Tom_L: wheel weights from a tire store
11:45 AM Loetmichel: Tom_L: in europe those are now made from zinc, not lead
11:45 AM Tom_L: wasn't sure where he was
11:46 AM JavaBean: i am in us, looking to start with about 200-ish pounds
11:46 AM Tom_L: old typesetting machines had lead letters
11:46 AM Loetmichel: easiest way here in europe would be trying to get some old starter batteries from cars at the scrapyard and melt them. but that can turn out tricky because there IS a mandatory deposit on those.
11:47 AM Tom_L: you would likely get the most from those over another recycled source
11:47 AM Tom_L: there's bound to be some cars with lead weights still...
11:51 AM Tom_L: stained glass shop
11:51 AM Tom_L: doubt they reuse the lead
11:52 AM JavaBean: no "stained glass" shops within hours of me
11:55 AM Tom_L: https://www.youtube.com/watch?v=p4KmaXfoIKE
11:55 AM Tom_L: not necessarily for the video but he lists a few in his comments
11:55 AM Tom_L: roof tin
11:56 AM Tom_L: stand at the end of a firing range and catch it as it goes by
11:58 AM JavaBean: pricing to make lead plates for batteries... the lead needs to be as pure as possible
11:59 AM Tom_L: recycled batteries would be a good one then
12:00 PM Rab: Tom_L, type metal is a tin/lead alloy similar to solder, although it's still pretty heavy. But, please don't melt down old lead type.
12:01 PM Tom_L: yeah it's worth more as an antique i'm sure
12:01 PM Rab: Worth more to letterpress printers who would like to use it as intended.
12:02 PM Tom_L: i'm sure it's getting scarce
12:03 PM JavaBean: automotive batteries, even deep cycle batteries are apparently not good sources for lead. they use a lead mesh to hold a different material that is the primary creator of electricity. those pieces coming loose and moving is allegedly the primary cause of "shorted cells" in abused batteries
12:03 PM roycroft: most stained glass makers don't use much came these days - they mostly use the copper foil technique
12:03 PM roycroft: came is primarily used for borders
12:04 PM roycroft: if for that
12:05 PM Tom_L: it's uses are being replaced all over now
12:05 PM Rab: Sometimes you can find nuclear equipment with serious lead shielding for either an internal source, or to keep a detector very quiet. I built my CNC router from the frame of a gamma counter which had a pretty serious lead shielding "pig": http://reboots.g-cipher.net/rabbot/image/compugamma.jpg
12:05 PM JT-Cave: shipping 60 pounds of lead is not cheap
12:06 PM Tom_L: nope
12:06 PM Tom_L: better to find it local if possible
12:06 PM Rab: My friend bought the detector at scrap prices to salvage the "pig" for his own detector, so the frame was up for grabs.
12:06 PM JT-Cave: I had those finials shipped from Baltimore and it cost me $75
12:07 PM Tom_L: grab a metal detector and head back east. you're likely to find plenty in some fields
12:10 PM jymmmm: USPS priotity mail flat rate up to 75 lbs
12:12 PM jymmmm: Rab: And that's no way to treat a Model M =(
12:18 PM Rab: jymmmm, a sad state of affairs, I agree.
12:19 PM jymmmm: Rab: Although, it'll probably still work once cleaned up
12:31 PM CaptHindsight: Tom_L: watched a bit last, till i fell asleep, will see the rest later
12:32 PM Tom_L: curious to see what you think
12:32 PM CaptHindsight: Tom_L: the problem is that there is much missing and corrupted evidence
12:32 PM Tom_L: yeah
12:32 PM CaptHindsight: like 9-11
12:33 PM CaptHindsight: give us the evidence and we'll sort it out for you, gut the official story does not add up
12:33 PM CaptHindsight: gut/but
12:34 PM Tom_L: it's apparent they were hiding something
12:34 PM CaptHindsight: so there is lots of leeway to embellish
12:34 PM CaptHindsight: certainly
12:35 PM CaptHindsight: but as we have seen in the past 50 years, it really doesn't matter to most people
12:35 PM CaptHindsight: they buy the official story
12:35 PM CaptHindsight: nothing is done about the corruption
12:36 PM CaptHindsight: and the evidence gets "lost"
12:38 PM CaptHindsight: why is evidence secret for 50+ years?
12:40 PM Tom_L: by then it doesn't matter
12:41 PM CaptHindsight: similar patterns, video gets confiscated, evidence destroyed, distract, push narratives, make it confusing, attack those that question
12:42 PM Tom_L: dunno if you were around when it happened but i watched it live
12:43 PM CaptHindsight: was at home, TV off
12:43 PM Rab: Tom_L, you were in Dallas?
12:43 PM Tom_L: lots of confusion and way too many ppl around
12:43 PM Tom_L: Rab, no
12:43 PM Tom_L: tv
12:45 PM CaptHindsight: same with 9-11, try to find a copy of the original videos, run the numbers
12:46 PM CaptHindsight: how do i get material samples?
12:47 PM CaptHindsight: if the other tests are accurate then there was funny business that doesn't match the official story
12:48 PM Tom_L: sry you'll have to wait 50 yrs
12:48 PM CaptHindsight: yet a building not hit imploded across the street
12:49 PM CaptHindsight: but the not the 150 year old church across the street
12:49 PM CaptHindsight: and all the other older more fragile buildings, amazing luck
12:49 PM Tom_L: funny things happen when planes hit buildings
12:50 PM CaptHindsight: I used to stay across the street from the towers at the hyatt
12:51 PM Tom_L: good you weren't there that day
12:51 PM CaptHindsight: they had some broken glass
12:52 PM CaptHindsight: I wasn't back until sometime that winter, there was still some vertical columns visible from across the street
12:53 PM _unreal_: I saw the towers ONCE in person WAYYY back
12:53 PM _unreal_: 1997 ish?
12:54 PM _unreal_: bck when my father lived in puerto rico. he'd fly me down for the summer. ONE year I had to go to NY air port.
12:54 PM _unreal_: and the plane I went on I was suposed to be on the port side. SOMEASS took my seat because it was the side to see the statue of liberty
12:54 PM _unreal_: so I was forced to sit on the other side.
12:55 PM _unreal_: went RIGHT past the towers felt like I was 500 ' away
12:55 PM _unreal_: I was prob 3000' away
12:55 PM CaptHindsight: Tom_L: what I see are similar patterns in coverups
12:55 PM _unreal_: but regardless felt like I was all but grazing them
12:56 PM CaptHindsight: like Putin creating instability with NATO nations and neighbors
12:57 PM CaptHindsight: how China handles things, HK, south china sea, internal issues etc
12:58 PM CaptHindsight: USA history of south Asia, south America and the middle east
01:06 PM robotustra: morning
01:13 PM CaptHindsight: https://www.popularmechanics.com/science/a33327626/scientists-encoded-wizard-of-oz-in-dna/
01:15 PM robotustra: only clay plates
01:15 PM CaptHindsight: DNA is easy to make but this article is only focused on error correction which is trivial
01:15 PM robotustra: DNA storage is too fragile
01:16 PM CaptHindsight: yes, so i wonder why they are so interested in rapid synthesis
01:17 PM CaptHindsight: lots of other methods to store data as compact and efficiently and that is far more robust
01:17 PM robotustra: to create new creatures?
01:17 PM CaptHindsight: hide data in your cells?
01:17 PM robotustra: definetely not for storing data
01:18 PM robotustra: it's just one usecase
01:18 PM CaptHindsight: synthesizing a patch for a bad gene is easy
01:18 PM CaptHindsight: even the whole gene
01:18 PM robotustra: human DNA double and replicates itself in 40 seconds during call division
01:19 PM CaptHindsight: they don't cover the method used or how long in the article
01:19 PM robotustra: but I see where the main problem - is fast reading of DNA
01:20 PM CaptHindsight: nanopores
01:20 PM CaptHindsight: the read head
01:20 PM robotustra: is it implemented or just your fantasy?
01:20 PM CaptHindsight: you draw the DNA through
01:21 PM CaptHindsight: been around for a while
01:21 PM robotustra: what is the reading speed of this?
01:21 PM robotustra: how many codones per second?
01:21 PM robotustra: 10? 20?
01:21 PM robotustra: 200?
01:22 PM robotustra: it's insanely small
01:22 PM CaptHindsight: yes
01:22 PM CaptHindsight: <1nm
01:22 PM robotustra: 1 nm it's about 10 codones
01:23 PM CaptHindsight: in dia, XY
01:23 PM robotustra: I think there is a faster way - to line up molecule in a groove and do AFM above the groove
01:24 PM CaptHindsight: tiny hall sensor-like
01:24 PM robotustra: no, just electric field like in AFM
01:24 PM CaptHindsight: that is only one "head"
01:24 PM robotustra: with diamond tip
01:24 PM CaptHindsight: I haven't read about anyone stacking them
01:24 PM CaptHindsight: but it's obvious
01:25 PM CaptHindsight: more heads are better than one
01:25 PM robotustra: I saw somewhere article how RNA is assemled on a flat surface with litear groovs
01:25 PM CaptHindsight: I'm sure somebody got funded to make faster read heads
01:26 PM CaptHindsight: "tiny hall sensor-like" was in reference to the nanopores, not what you mentioned, to be clear
01:28 PM CaptHindsight: the whole idea to use DNA for data is dumb unless you want to embed data into living things
01:28 PM roycroft: yay
01:29 PM roycroft: my outdoor work is done, other than setting up sprinklers an hanging out laundry
01:29 PM roycroft: the heat advisory starts in just over a half hour
01:29 PM roycroft: and i turned the ac on in my garage at 6 this morning
01:29 PM roycroft: it's actually cold out there right now
01:29 PM roycroft: which means it will still be tolerable by late afternoon
01:31 PM CaptHindsight: roycroft: same pattern for you all week or?
01:31 PM CaptHindsight: we are hot today by mild for the next 10 days
01:32 PM CaptHindsight: haven't read the news yet, did Texas get battered by a hurricane?
01:35 PM CaptHindsight: robotustra: Intel has a group working on DNA storage and retrieval but they were keeping thing big vs small since they were concerned about the logistics
01:36 PM CaptHindsight: so unless somebody has an app for this the DNA as data seems like a money pit
01:38 PM _unreal_: https://olivieres.com/products/typewriter-style-mechanical-wired-wireless-keyboard?fbclid=IwAR0BLe24lAW_Vk53MTyB4BfzSdW27LX6ddb0IEAO-d4YUM8RFoz2JUF-DCA
01:38 PM _unreal_: NIFTY
01:38 PM robotustra: I heared russians already made a vaccine. It is true?
01:39 PM CaptHindsight: robotustra: what I heard, but there are several being tested by a few countries
01:39 PM CaptHindsight: a couple look good so far
01:40 PM CaptHindsight: Google for test results, several papers
01:40 PM robotustra: did any capitalist country succeeded?
01:40 PM CaptHindsight: not yet
01:41 PM CaptHindsight: lots of PR and funding, even a 2 Billion $ pre order
01:41 PM robotustra: so if russians give this vaccine for free to any country - tey fuck up all vaccine business for capitalists approach
01:42 PM robotustra: and I'm tretty sure they can give it for free
01:42 PM CaptHindsight: robotustra: they are also finding some immunity in lots of people likely based on SARS-1 exposure
01:42 PM CaptHindsight: sure
01:42 PM robotustra: russians made a vaccine against ebola
01:42 PM CaptHindsight: weaponize the vaccine
01:43 PM CaptHindsight: https://scitechdaily.com/scientists-uncover-evidence-that-a-level-of-pre-existing-covid-19-sars-cov-2-immunity-is-present-in-the-general-population/
01:43 PM robotustra: capitalism fails in medicine heavily, it's sad
01:43 PM CaptHindsight: well if $ is the only goal
01:44 PM CaptHindsight: they act like kids, if they don't win then nobody does
01:44 PM robotustra: but it's the only goal in capitalism
01:44 PM robotustra: there is no other goals, just $
01:44 PM robotustra: it is
01:45 PM CaptHindsight: we could have fixed lots of things if that was the goal
01:45 PM robotustra: they do not see futher in the future, if everyone dies around you - what you will do with your $$$?
01:45 PM CaptHindsight: doesn't matter
01:45 PM CaptHindsight: it's compulsive obsessive
01:45 PM CaptHindsight: only with money and power
01:45 PM robotustra: I state 2 things: 1) there is no medicine in USA. 2) There is no private property in USA
01:45 PM CaptHindsight: not rational
01:46 PM robotustra: Prove me that I'm wrong
01:46 PM CaptHindsight: please define medicine
01:47 PM CaptHindsight: 2) we have evident domain, so you don't really own it
01:48 PM robotustra: It's hard to explain, I just give you 1 example - you are mom, gonna go to work and your child is sick
01:48 PM robotustra: what you gonna do in USA and russia?
01:48 PM robotustra: can you call a doctor to home for free?
01:48 PM robotustra: for USA - no, for russia YES
01:49 PM robotustra: no medical service in USA
01:49 PM CaptHindsight: there is more money in treatments than cures, Goldman sachs https://www.cnbc.com/2018/04/11/goldman-asks-is-curing-patients-a-sustainable-business-model.html
01:49 PM robotustra: to make MRT - in Canada you have to wait half of year, in Belarus - you can get it for free in a week
01:49 PM robotustra: or emmideately
01:50 PM CaptHindsight: robotustra: the USA has along standing tradition of equating ones personal value to the amount of money under their control
01:50 PM CaptHindsight: along/ a long
01:50 PM robotustra: to make root canals in Canada - it costs $1500 for one tooth, and wait for 2 weeks, in belarus - the same day $200
01:51 PM robotustra: As I told - the only goal of camitalism - get more $$$
01:51 PM robotustra: all other things coming from that
01:51 PM CaptHindsight: robotustra: most people in the USA are kept ignorant, poor and busy. They don't even care what goes on elsewhere.
01:52 PM robotustra: in usa there are bubbles in 1) housing, 2) education 3) medicine
01:52 PM CaptHindsight: you just tell them it's commie or boogie man to have socialized healthcare
01:52 PM robotustra: it's in any country
01:52 PM robotustra: in belarus it's about 60-70% of ignorant people
01:53 PM robotustra: I just want to say - it's possible to make great country if you care about people
01:53 PM robotustra: and it's not that hard
01:53 PM CaptHindsight: the difference here is that a few have managed to manipulate things to their advantage and skim money off things like medicine
01:53 PM CaptHindsight: i agree
01:54 PM robotustra: just give them free home, free education and free medicine
01:54 PM CaptHindsight: but if you train people to not give 2 shits about others
01:54 PM CaptHindsight: you get the USA
01:54 PM robotustra: anyway it will come back in taxes
01:54 PM gregcnc: too many get caught up in me, me, me
01:55 PM CaptHindsight: robotustra: you are right, it's not too hard to do
01:55 PM CaptHindsight: and we have had the $$ to pay for lots of it all along
01:55 PM CaptHindsight: we just don't want to
01:55 PM robotustra: who "we"?
01:56 PM robotustra: people of USA?
01:56 PM robotustra: or government?
01:56 PM CaptHindsight: the majority of the US
01:56 PM robotustra: so they suffer from own ignorance?
01:56 PM CaptHindsight: well a good half
01:56 PM CaptHindsight: based on patterns
01:56 PM CaptHindsight: oh yeah
01:56 PM robotustra: that's sad
01:56 PM CaptHindsight: #1 in ignorance here, prove me wrong :)
01:57 PM gregcnc: ho do you fix it
01:57 PM CaptHindsight: schooling and socialization has worked so well to dumb things down
01:58 PM CaptHindsight: when you see a focus on education then you might see change
01:58 PM CaptHindsight: and it will take time
01:58 PM robotustra: yeah, make good aducation
01:58 PM robotustra: there is no education in USA
01:59 PM CaptHindsight: but I figure it will be a catastrophe that changes things here
01:59 PM gregcnc: education is looked down upon
02:00 PM CaptHindsight: worse pandemic, civil war, death of the Kardashians etc
02:00 PM CaptHindsight: little was learned from Reagan, Bush and now Trump
02:00 PM robotustra: I'm cutting cast iron with a hack saw
02:00 PM robotustra: and I'm happy
02:00 PM CaptHindsight: like butter?
02:01 PM robotustra: no
02:01 PM robotustra: I need to make an extender for the nut to make a new nut for Y axis
02:01 PM robotustra: the nut from mcmaster is a bit short
02:02 PM gregcnc: mcmaster in belarus?
02:02 PM robotustra: in montreal
02:02 PM robotustra: I'm in montreal for 10 years
02:02 PM robotustra: latest 10 yeas I'm a "canadian"
02:03 PM CaptHindsight: robotustra: have you noticed a shift in Canada to the ignorance in the USA?
02:03 PM robotustra: I think canadians a bit more educated
02:03 PM CaptHindsight: some other Canadians have commented
02:03 PM robotustra: at least in montreal
02:04 PM robotustra: I know some clever muricans
02:04 PM CaptHindsight: the whole world has some clever people scattered about
02:05 PM robotustra: so I can't make any statements about ignorance of americans because I don't like there for a long period of time
02:05 PM robotustra: All muricans I worked with were clever and educated
02:05 PM CaptHindsight: stay where it's safer
02:05 PM robotustra: but it's aerospace
02:05 PM CaptHindsight: you're not missing much
02:06 PM robotustra: I'm in a bouble
02:06 PM robotustra: surrounded with clever people
02:06 PM CaptHindsight: i know, when I go outside mine it gets really depressing fast
02:07 PM robotustra: in montreal almost any person know at least 3 language: en, fr, and native
02:07 PM CaptHindsight: but you see how well trained they to shoot themselves in the foot
02:07 PM robotustra: today I was forced to buy mask to pay for my goods on cassier
02:08 PM robotustra: it was funny
02:08 PM CaptHindsight: they still use religion on them as well, warped Christianity mostly
02:08 PM robotustra: I walked around the shop for a 30 min and to make 1 min transction on casser I have to buy a mask from them
02:09 PM CaptHindsight: well socialization vs science
02:09 PM robotustra: nobody told me I have to wear a mask on entrance
02:09 PM CaptHindsight: simple rules for simple people
02:09 PM CaptHindsight: one thing at a time
02:09 PM gregcnc: that stuff is crazy here
02:09 PM CaptHindsight: repeat daily
02:10 PM CaptHindsight: 2 week memory
02:11 PM CaptHindsight: actual facts don't matter, facts are popular opinion
02:11 PM CaptHindsight: they matter
02:11 PM CaptHindsight: it's evil genius
02:11 PM gregcnc: it's crazy
02:12 PM robotustra: strange things, before I was telling ppl in IRC that I'm not canadian, now I'm telling ppl that's I'm canadian :)
02:12 PM robotustra: I don't know when it's reverted :)
02:13 PM robotustra: didn't noticed that
02:13 PM CaptHindsight: when you feel at home
02:13 PM robotustra: possible
02:14 PM CaptHindsight: my parents were similar, their birth places changed countries
02:14 PM robotustra: https://imgur.com/gallery/3ZEqVi9
02:14 PM CaptHindsight: and they skipped around a lot before landing in the USA
02:14 PM CaptHindsight: had thick accents until their passing
02:18 PM robotustra: oh I think I know what device I have to buy: metal saw
02:19 PM robotustra: immigration for me passed without much stress
02:19 PM robotustra: but canada is prepared to accept immigrants, not sure about usa
02:20 PM CaptHindsight: here immigrants bad unless they are conservative
02:21 PM robotustra: you mean immirgants should accept local rules?
02:21 PM CaptHindsight: no, vote conservative
02:22 PM CaptHindsight: the USA has been becoming less white for decades
02:23 PM CaptHindsight: they are trying to stop them from becoming a minority
02:24 PM robotustra: you are too delicate
02:24 PM robotustra: whites in usa - are already a minority :)
02:24 PM CaptHindsight: the census projection is ~2045 for that transition
02:24 PM robotustra: but it's not proven
02:25 PM robotustra: https://i.imgur.com/KRfeRR9.jpg
02:28 PM robotustra: I don't know how it will be in 2045
02:28 PM CaptHindsight: still there are lots of great scientists and engineers down here
02:29 PM robotustra: it's all about education
02:29 PM CaptHindsight: what seems to be getting lost on those just out of school is how things actually work inside
02:29 PM CaptHindsight: especially with software and networks
02:30 PM CaptHindsight: if the US had to rebuild manufacturing quickly it would be up to the older people to get it running quickly
02:31 PM CaptHindsight: or everything would be made from arduinos
02:31 PM CaptHindsight: they don't seem to want to learn from what we got passed down or our mistakes
02:31 PM gregcnc: how many really get into what they do? vs. getting paid
02:32 PM CaptHindsight: yeah, work, don't get fired
02:32 PM gregcnc: and throw anyone you can under the bus
02:32 PM CaptHindsight: why so much is broken or "almost works"
02:34 PM _unreal_: black is becoming a minoroty as wel
02:34 PM _unreal_: in the usa
02:35 PM _unreal_: and black people are becoming so intermingled they are lossing there black for a more pale dark
02:36 PM CaptHindsight: the projections decades ago was towards Latino and Hispanics
02:36 PM robotustra: there about 12% of blacks in murica
02:37 PM robotustra: latinos is growing up?
02:37 PM CaptHindsight: https://www.baltimoresun.com/resizer/5UQyfo09ZFLbl9zxrtdCEuFmxNA=/415x311/top/www.trbimg.com/img-57ccdf0a/turbine/sdut-us-whites-falling-to-minority-in-under-5-age-group-2013jun13
02:37 PM robotustra: tell me the difference between latino and hispanic?
02:37 PM CaptHindsight: ^^ from https://www.baltimoresun.com/opinion/op-ed/bs-ed-op-0809-minority-majority-20170808-story.html
02:38 PM CaptHindsight: if you go back far enough there is little difference
02:38 PM robotustra: and why they call white ppl - caucasians
02:38 PM CaptHindsight: https://en.wikipedia.org/wiki/Hispanic_and_Latino_(ethnic_categories)
02:40 PM CaptHindsight: we should use BMI vs race
02:41 PM CaptHindsight: racists need it to be race
02:42 PM CaptHindsight: how different things would be without racism
02:42 PM Wolf__: should be those with common sense vs the fucking clueless
02:43 PM CaptHindsight: psychiatrists use right handed vs left handed
02:44 PM CaptHindsight: when did we cross that tipping point of not being able to rationally converse?
02:44 PM CaptHindsight: it's like dealing with persons with disorders
02:45 PM CaptHindsight: you can't be rational with an eating disorder
02:46 PM CaptHindsight: just eat, no you are too thin already
02:46 PM CaptHindsight: 92lbs at 5ft 8in is not healthy
02:46 PM CaptHindsight: but I look fat!!
02:47 PM syyl: thats like telling someone with depressions to "just be happy, ok?"
02:47 PM CaptHindsight: same yeah
02:47 PM CaptHindsight: so what works in those situations?
02:48 PM CaptHindsight: behavioral modifications and training/learning
02:48 PM gregcnc: a lot of effort vs walking away
02:48 PM CaptHindsight: how do you do that with someone that does not recognize their issues?
02:48 PM syyl: some can learn how to deal/live with it
02:49 PM CaptHindsight: towel heads are just bad and it's important to me which bathroom you use
02:50 PM CaptHindsight: trickle down economics
02:51 PM CaptHindsight: invisible angry man in the sky said so
02:52 PM syyl: batman?
02:52 PM _unreal_: latest version https://drive.google.com/file/d/1unJZi6cQep_Ge87ULs1OBjAPKdhAMheC/view?usp=sharing google sketch up version
02:52 PM _unreal_: I doubt any of you use design spark
02:55 PM CaptHindsight: what i don't see in the USA is anyone trying to unite the sane and educated
02:56 PM CaptHindsight: just manipulate the ignorant
02:56 PM * infornography drinks Brawndo
02:57 PM gregcnc: they don't all belong to one political party?
02:57 PM Wolf__: mostly…
03:00 PM CaptHindsight: past few decades has been make a mess, do very little, make a mess, do very little to improve things, make big mess
03:00 PM _unreal_: the biggest problem lack of education and HURD mentality.
03:01 PM CaptHindsight: it has all benefited those on top
03:02 PM CaptHindsight: it's only a minority of those badly effected by it that seem to be aware or care
03:04 PM CaptHindsight: no push back
03:11 PM CaptHindsight: do scrap yards pick up metal? How much is the minimum?
03:12 PM CaptHindsight: I see those drum dollies https://www.amazon.com/TUFFIOM-Non-Tipping-Casters-Handling-Industrial/dp/B07QQP9GBG
03:12 PM gregcnc: put it out back and hope the guy with the overloaded jalopy come by?
03:12 PM CaptHindsight: but how do you empty without a forklift or crane?
03:12 PM CaptHindsight: maybe, they don't take my metal drums
03:12 PM CaptHindsight: they did once but never again
03:13 PM CaptHindsight: the local yard wants them cut open and rinsed out
03:13 PM CaptHindsight: some guy must have though goldmine and then they yard didn't take them
03:13 PM CaptHindsight: though/thought
03:17 PM gregcnc: I don't think anyone comes if you can't fill a rolloff regularly
03:17 PM infornography: poor people will come and pick up your scrap metal
03:19 PM infornography: some of the 36% of people who can't make their mortgage payment this month may haul it off
03:22 PM roycroft: i just did some fancy rationalizing
03:22 PM roycroft: the ac in my office has been failing for three years
03:23 PM roycroft: it barely works and it's really noisy
03:23 PM roycroft: i work full time from home now
03:23 PM roycroft: jerry's had some nice units on sale for $148 (who puts air conditioners on sale on one of the hottest days of the year anyway?)
03:23 PM roycroft: so i figured that to maintain my general health and well-being i needed to get a new one
03:24 PM roycroft: and i could pay for it out of my savings account i use for medical deductables and co-pays
03:24 PM roycroft: since the ac is health-related
03:24 PM roycroft: i don't see any flaws in that logic
03:24 PM infornography: nice
03:24 PM roycroft: but i'm not looking for any :)
03:24 PM CaptHindsight: I connected 2 more units and it made a big difference
03:24 PM roycroft: yeah, and fortunately it fit right in
03:24 PM roycroft: it was a 20 minute job
03:24 PM roycroft: and it's blowing cold air
03:25 PM roycroft: it will be an hour or so before the office is nice and cool, but that's fine
03:25 PM CaptHindsight: 2 more tons of indoor unit to the minis outside
03:25 PM roycroft: my garage is still quite cool, and since i found some 7/16" rod at jerry's i'm able to make the parts i need without having to worry about turning 1/2" rod down to 7/16"
03:25 PM roycroft: so i can go stand by the lathe now and put some threads on that rod
03:25 PM CaptHindsight: 24ft ceilings here and it's 96F outside, 72F inside below 8ft
03:25 PM roycroft: the lathe being 1m away from the ac unit
03:26 PM CaptHindsight: humidity inside is ~40%
03:26 PM CaptHindsight: even at night
03:27 PM CaptHindsight: roycroft: for $140 it's well worth it
03:27 PM CaptHindsight: the unit AC section at the local stores here is almost bare
03:29 PM roycroft: it's only 5,000 btu
03:29 PM roycroft: but my office is really small
03:29 PM roycroft: so it will be fine
03:29 PM roycroft: i almost want to get another one for my bedroom
03:29 PM roycroft: they're selling like hotcakes though, and they may be out of them by now
03:30 PM CaptHindsight: it takes the edge off and lowers humidity
03:30 PM roycroft: besides, i'd have to build a frame and stuff for the bedroom - it doesn't have an ac currently
03:30 PM roycroft: the climate where i am is the opposite of the east coast - hot, dry summers and cool, humid winters
03:31 PM roycroft: right now the temperature is 32 degrees and the humidity 28%
03:31 PM XXCoder: western wa eh
03:31 PM CaptHindsight: i had an all concrete concrete shop ~3000 sq ft that only ad dehumidifiers and it felt much better
03:31 PM CaptHindsight: ad/had
03:31 PM roycroft: i'm in western oregon
03:31 PM roycroft: same thing as western washington
03:31 PM XXCoder: capt I guess its quite tall building
03:32 PM XXCoder: yeah roy
03:32 PM roycroft: i'm in between the coast range and the cascades
03:32 PM XXCoder: the best area
03:32 PM roycroft: i'd like to live on the caost
03:32 PM CaptHindsight: heh, seems whenever I pass connect through Portland or Seattle it's grey soup
03:32 PM roycroft: coast
03:32 PM roycroft: but i can't afford it
03:32 PM CaptHindsight: I don't think you actually have any city there :)
03:32 PM roycroft: capthindsight: we have really nice weather sometimes
03:33 PM XXCoder: buy a old barge and yturn it into home heh
03:33 PM roycroft: but we always put the nice weather away until we've gotten rid of the tourists
03:33 PM roycroft: we like to bring out the rain when the tourists show up
03:33 PM XXCoder: cheap at million bucks! https://www.oceanmarine.com/detail.cfm?250%27%2Dx%2D48%27%2DDeck%2DBarge%2D%2D%2DFile%23%2D15376&product_id=15376&category_current=6&category_current_sub=24
03:33 PM roycroft: not having any decent size cities is why i can't afford to live on the coast
03:33 PM CaptHindsight: grey soup, grey soup, grey soup, runway lights, touch down, terminal
03:34 PM roycroft: this new ac is definitely a win
03:34 PM roycroft: it's already cooler in here than it was early this morning
03:34 PM * roycroft heads back to the shop
03:35 PM CaptHindsight: we keep the shop cool in winter <62F
03:35 PM CaptHindsight: so anything over 72F in summer seems like an oven
03:35 PM XXCoder: 80f here as "hot"
03:36 PM XXCoder: this week will be all 80f, except monday at 85f
03:36 PM XXCoder: *88f
03:38 PM gregcnc: huh a 5000btu ac only uses 4A
03:39 PM XXCoder: greg usually its compressor that uses lots power
03:39 PM XXCoder: its probably not using it yeet
03:40 PM XXCoder: yet
03:40 PM gregcnc: no cooling of compressor isn't on
03:45 PM jymmmm: gregcnc: S you can use 2 per outlet =)
03:46 PM jymmmm: So*
03:46 PM gregcnc: heh
03:46 PM gregcnc: EER rating = cooling BTU/W input LOL
03:47 PM jymmmm: gregcnc: Now, it's rated at 4A (including inrush at startup), how much after that?
03:47 PM gregcnc: it's actually 450W running
03:48 PM jymmmm: Measured or Rated?
03:49 PM gregcnc: rated. it's expedted to vary a bit if you measure
03:51 PM jymmmm: It's nice to use a killawatt meter for such things, then you get a better idea of what the actual consumption is
03:51 PM gregcnc: yeah, i watched mine
04:23 PM _unreal_: overloaded jalopy LOL, thats florida on trash days
05:06 PM jymmmm: CaptHindsight: If I connect a 16.8 battery to a buck converter set to 12V output maintin it's voltage when the battery gets down to (let's say) 10V ?
05:10 PM _unreal_: a buck converter you may need to maintain a voltage above a certain point
05:10 PM _unreal_: more then likely infact
05:11 PM _unreal_: because your going to draw more current the lower the voltage goes if your maintaining a higher voltage at a set current
05:11 PM _unreal_: I would expect you must maintain at least two volts positive above the set voltage for the output stage of the DC DC unless it states other wise
05:12 PM _unreal_: t4nk_freenode, you live?
05:17 PM t4nk_freenode: yea
05:30 PM veegee: andypugh regarding your neutrik connector, what are you using it for?
05:30 PM veegee: I'm missing logs after you posted that for some reason
05:31 PM andypugh: veegee: https://photos.app.goo.gl/7RQQjgXpjedY1jnLA
05:32 PM veegee: RTD? Thermocouple?
05:32 PM andypugh: K-type thermocouple, but the Neutrik is the 240V to the heating coils.
05:32 PM veegee: Ah nice
05:33 PM andypugh: 20A rating @240V.
05:33 PM veegee: Where did you get it? I'm planning on buying a whole bunch of those to convert my electric tools
05:33 PM veegee: The ones that are rated for disconnect under load anyway
05:34 PM veegee: I had another incident of high speed bits randomly getting out of balance in the shaft and vibrating my whole arm, this time with an air die grinder at 50,000 RPM
05:34 PM andypugh: I can’t remember, possibly eBay, maybe RS components. I have bought some from a local stage electrics / PA supplier.
05:34 PM veegee: at least the coupler was easy to quickly disconnect with the other hand
05:35 PM andypugh: I have tried disonnecting Speakons with 300V DC on them. That didn’t go well.
05:35 PM andypugh: But at least it was cheap to replace the charred remains, and skin grows back.
05:45 PM _unreal_: t4nk_freenode, https://drive.google.com/file/d/1unJZi6cQep_Ge87ULs1OBjAPKdhAMheC/view?usp=sharing
05:46 PM _unreal_: thats in google sketchup format. there is a viewer app for phones
05:50 PM t4nk_freenode: my puter doesn't do that
05:51 PM _unreal_: do you have a phone
05:51 PM t4nk_freenode: sure
05:51 PM _unreal_: if you have a phone GO TO the app store and instlal google sketchup viewer
05:51 PM t4nk_freenode: I don't think so ;)
05:52 PM _unreal_: then you can view it full 3D cad drawing
05:54 PM t4nk_freenode: is it an upgrade to your first cnc you built?
06:01 PM _unreal_: yes major
06:01 PM _unreal_: new spindle motor, and all new Z
06:02 PM _unreal_: I'll snap real photos when more of it is assmbled
06:03 PM t4nk_freenode: I'm thinking of maybe buying some 3d printer
06:25 PM _unreal_: https://drive.google.com/file/d/1L1O4iV255lWyKWPc14CdUmzafI8XcM6K/view?usp=sharing https://drive.google.com/file/d/1WynZavk0CKzLeARJTRBetXJetmMjESBy/view?usp=sharing https://drive.google.com/file/d/1ZO5nARscb7JPjj5oPO0Y4dzkFlYSssGs/view?usp=sharing
06:25 PM _unreal_: there are some CAD drawings
06:26 PM Tom_L: mounting screws clear each other?
06:27 PM _unreal_: which ones?
06:27 PM Tom_L: any / all
06:28 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_Plate1.jpg
06:28 PM Tom_L: i had fun making sure they all cleared
06:28 PM _unreal_: the only only one's I HAVE ALREADY, should have to make clearance for is the direct motor mount for the spindle its self. I had to pocket 4 ares for the car mounting screws
06:28 PM Tom_L: done one a sherline i may add
06:34 PM _unreal_: sucks having to do stuff so slow right now
06:35 PM _unreal_: I'm hopping when I get this NEW z setup
06:35 PM _unreal_: I can increase my speed a big...
06:35 PM Tom_L: why slow?
06:35 PM Tom_L: oh making stuff on an old mill?
06:35 PM _unreal_: A: I'll have an upgraded spindle that does 14k RPM. my current one is rated for 12k and I dont think it does
06:35 PM _unreal_: because my machine is hand built and has flex in it
06:35 PM Tom_L: mine does 5
06:35 PM Tom_L: don't feel so bad
06:36 PM _unreal_: about 40% of my flex is from the Z
06:36 PM Tom_L: mine has a little but i can live with it
06:37 PM Tom_L: got an indexer coming for it
06:37 PM _unreal_: I'm milling aluminum right now with a two flute 1/8th bit at .75mm per pass 2mm pockets
06:37 PM _unreal_: 8mm diam as I recall
06:37 PM _unreal_: no 6.35mm diam
06:38 PM Tom_L: bolt recess holes?
06:42 PM robotustra: is it possible to broach on g0704?
06:43 PM Tom_L: it's possible to broach on a drill press
06:44 PM robotustra: I mean is it ok for quill?
06:45 PM Tom_L: i'd use an arbor press
06:45 PM Tom_L: a progressive broach?
06:45 PM robotustra: I expecter that
06:45 PM XXCoder: theres press broaching too
06:45 PM robotustra: no, just single rutter
06:45 PM Tom_L: or a bottoming broach
06:45 PM XXCoder: you just need a press for that one
06:45 PM robotustra: cutter
06:46 PM _unreal_: interesting ESTLcam crashed on me
06:46 PM robotustra: like a shaper
06:47 PM robotustra: I mean to broach like in this video but on g0704
06:47 PM robotustra: https://www.youtube.com/watch?v=JFuLjT3QmwA
06:48 PM Tom_L: you could try but i'm not sure i would
06:49 PM robotustra: because g0704 is too flimsy?
06:50 PM Tom_L: i'm not familiar with it
06:50 PM Tom_L: you could try it
06:52 PM robotustra: I'm thinking in term of doing key holes in aluminum pulleys
06:52 PM robotustra: or doing pulley itself
06:52 PM Tom_L: _unreal_, i found these used for my bolt countersinks: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/countersink2.jpg
06:52 PM Tom_L: instead of interpolating them
06:53 PM _unreal_: I want
06:53 PM Tom_L: the pilot on the lower one is replaceable but the screw was stripped out
06:53 PM Tom_L: it still works
06:53 PM Tom_L: free
06:54 PM Tom_L: so i did the pilot holes on the cnc and had the drill press set up with these
06:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/countersink1.jpg
06:55 PM Tom_L: you can see the broken screw hole
06:55 PM robotustra: https://imgur.com/a/GE7ZliE
06:55 PM robotustra: I do interpolate
06:56 PM Tom_L: i have too but this was quicker
06:56 PM robotustra: but I probably buy that cutters because yes, it's much faster
06:56 PM Tom_L: i got them free cause they were used
06:57 PM _unreal_: t4nk_freenode, I posted some cad drawings
07:00 PM roycroft: i have some of those countersink cutters, tom_l
07:00 PM roycroft: they make life easier for sure
07:00 PM roycroft: er, counterbore cutters
07:00 PM robotustra: https://www.amazon.ca/Cutter-Countersink-Flutes-Milling-Aluminum/dp/B07QWD5G3W/ref=sr_1_4
07:00 PM _unreal_: so I have a few upgrades to my machine
07:00 PM * roycroft had a brain fart on that a while back and apparently still does
07:01 PM _unreal_: changing allllllll of the drive nuts to HDPE
07:01 PM _unreal_: the z is the last one to be upgraded
07:01 PM _unreal_: the z spindle is also a solid shaft. the current spindle is like a 1/4" shaft with an ER11 collet adapter press fit on it it
07:01 PM _unreal_: and only 200watt
07:02 PM _unreal_: moving upto 300watt. NOT a huge jump but I'm sure it will feel like it
07:02 PM _unreal_: then again this is a very small machine as far as its work area goes
07:02 PM roycroft: 50% is a pretty significant power gain
07:03 PM * roycroft is just checking email and cooling off for a bit
07:03 PM roycroft: it's comfortable in the garage shop
07:03 PM roycroft: it's downright cool in my office
07:03 PM roycroft: and it's hotter than blazes outside
07:03 PM roycroft: "only" 36, and not likely to get warmer
07:03 PM roycroft: but still
07:04 PM _unreal_: 50?
07:04 PM _unreal_: 200 to 300
07:04 PM _unreal_: thats a 3rd
07:04 PM robotustra: hm
07:04 PM _unreal_: 1/3 more powerful
07:05 PM robotustra: the same cutters on ebay $18
07:05 PM _unreal_: try being in south florida :)
07:05 PM _unreal_: its rather nice IMO outside
07:05 PM roycroft: it'a 100 watts more
07:06 PM roycroft: 100 is 50% of 200
07:06 PM roycroft: so it's a 50% increase
07:06 PM _unreal_: o,O ok
07:06 PM roycroft: your old device is 1/3 less powerful than the new one
07:06 PM CaptHindsight: robotustra: are those anti-plunge cutting end mills? :)
07:06 PM t4nk_freenode: yeh, I've seen em now, _unreal_
07:06 PM roycroft: but the new one is 50% more powerful than the old one
07:07 PM _unreal_: the other major bennifit is that the motor is going to be HARD mounted with a cast motor mount. where as the current setup is using more or less angle aluminum
07:07 PM roycroft: i had a use for my rotary table today, but i found that i had no way of mounting it vertically
07:07 PM roycroft: i'm going to need to make a fixture plate to do that
07:07 PM roycroft: so i did a really dodgy thing with a vee block and a clamp
07:07 PM roycroft: that i should probably not talk about
07:07 PM _unreal_: the angle aluminum setup has worked but it has UP defelection and has a tendency to RACK in lateral motions
07:08 PM roycroft: but i get my part made without any incident that endangered me or damaged the part
07:08 PM roycroft: i was rather surprised to find it was not possible to mount the rotary table vertically in its stock configuration
07:09 PM CaptHindsight: anyone know what they used for bearings in old 100-150 y.o. sewing machines?
07:09 PM CaptHindsight: https://chicago.craigslist.org/nch/atq/d/winnetka-antique-the-free-sewing/7163251724.html
07:09 PM roycroft: perhaps it mounts vertically easily on a bridgeport table, but not on my small table
07:09 PM roycroft: babbit?
07:10 PM _unreal_: I believe they used sleeve
07:10 PM _unreal_: lot of lube
07:11 PM _unreal_: CaptHindsight, WHOLY FUCK GET THAT!!!! do you know how much those are worth
07:11 PM CaptHindsight: what i figured but have not inspected
07:11 PM CaptHindsight: there was one near me for $25 looked new with accessories
07:12 PM CaptHindsight: and original wood table and paperwork from 1880
07:12 PM CaptHindsight: wedding gift
07:12 PM _unreal_: god damn..... thats like $2500
07:12 PM XXCoder: with one you could recreate the first gage blocks
07:12 PM _unreal_: if its in great shape and working
07:12 PM CaptHindsight: _unreal_: tons near me for $300 or less with tables
07:14 PM CaptHindsight: $20 https://milwaukee.craigslist.org/atq/d/milwaukee-antique-domestic-treadle/7166124440.html
07:15 PM CaptHindsight: https://milwaukee.craigslist.org/atq/d/fredonia-antique-new-home-sewing-machine/7163573610.html
07:18 PM CaptHindsight: tons for $10ea https://rockford.craigslist.org/atq/d/dixon-treadle-wheel-sewing-machine/7144572013.html
07:18 PM CaptHindsight: some look like boat anchors
07:19 PM jymmmm: CaptHindsight: If I connect a 16.8 battery to a buck converter set to 12V output maintain it's voltage when the battery gets down to (let's say) 10V ?
07:19 PM jymmmm: will it*
07:20 PM CaptHindsight: nope unless it is buck and boost
07:20 PM CaptHindsight: or SEPIC
07:21 PM CaptHindsight: a buck only will likely drop out ~2v above the output setting
07:21 PM CaptHindsight: like everyone else has said
07:23 PM jymmmm: CaptHindsight: Didn't see anything because my nick wasn't highlighted
07:23 PM jymmmm: ok thankss
07:23 PM CaptHindsight: no problem
07:24 PM Tom_L: CaptHindsight, gonna open an antique store?
07:24 PM Tom_L: jymmmm, jymmmm jymmmm jymmmm
07:24 PM Tom_L: hi!
07:24 PM CaptHindsight: https://www.powerstream.com/dc-buck-boost.htm
07:25 PM CaptHindsight: jymmmm, jymmmm jymmmm jymmmm ^^

07:27 PM CaptHindsight: _unreal_: I see them on ebay in good condition for maybe $800 at most
07:27 PM Tom_L: robotustra, i like the smaller of the two counterbores because you can replace the pilot
07:36 PM robotustra: Tom_L, and use only one mill for all sizes?
07:37 PM Tom_L: no
07:37 PM Tom_L: the idea is the pilot will gauld if you're not careful and you can replace it on that one
07:38 PM robotustra: ok
07:39 PM robotustra: I need to make power feed as soon as I can, I already tired to crank wheels :)
07:39 PM Tom_L: heh
07:40 PM Tom_L: power feed and DRO
07:40 PM robotustra: I'm too spoiled with cnc
07:40 PM robotustra: I already ordered DRO
07:40 PM Tom_L: cnc and a pendant and you have best of both
07:40 PM robotustra: I'll cnc it one day
07:41 PM CaptHindsight: someone should make a pendant with wheels you crank
07:41 PM CaptHindsight: XYZ
07:41 PM robotustra: I already have an idea how to modify it
07:42 PM CaptHindsight: and force feedback
07:42 PM CaptHindsight: OH how about a force feedback racing wheel that you steer the CNC through
07:43 PM CaptHindsight: and accelerator pedal for feed rate
07:44 PM CaptHindsight: this has to go on cnczone and hackaday
07:44 PM robotustra: not sure I can do force feedback
07:44 PM robotustra: I was thinking about it, but it's a bit complicated
07:45 PM CaptHindsight: camera on the spindle
07:45 PM CaptHindsight: like a truck drivers view only of the cutting edge
07:49 PM robotustra: is it possible to use boring head for face milling?
07:49 PM robotustra: or it's not good practice?
07:50 PM robotustra: instead of flycutter?
07:52 PM CaptHindsight: robotustra: this type? https://mae.ufl.edu/designlab/Advanced%20Manufacturing/Mill%20Boring/Boring%20on%20Mill.htm
07:53 PM robotustra: yeah
07:53 PM robotustra: for instance
07:53 PM Tom_L: robotustra, not a good idea
07:53 PM jymmmm: Tom_L: Hi
07:55 PM robotustra: ok, so it mean that I have to buy fly cutter too
07:55 PM Tom_L: boring heads are for making holes
07:55 PM CaptHindsight: fly cutters are usually on the lower price side of things
07:55 PM CaptHindsight: the holders
07:56 PM Tom_L: boring heads aren't
07:56 PM Tom_L: not good ones anyway
07:56 PM CaptHindsight: new fly cutter <$100
07:56 PM CaptHindsight: used boring bar >$100
07:56 PM CaptHindsight: holder
07:56 PM jymmmm: CaptHindsight: Thanks, trying to find in the 300W (20A) range
07:58 PM Tom_L: jymmmm, Hi Hi!
07:58 PM jymmmm: lol
07:59 PM jymmmm: It almost seems easier to use a boost than to find a buck and boost converter
08:03 PM CaptHindsight: https://www.ebay.com/itm/20A300W-Step-Down-Buck-Boost-Power-Adjustable-Charger-Board-DC-DC-Converter-Tool/254638586927 BUT...
08:04 PM CaptHindsight: mount it on a big aluminum plate or heat sink and add a fan
08:12 PM CaptHindsight: jymmmm: other than the 2 on ebay and amazon https://www.mouser.com/ProductDetail/Cincon/CFB400W-24S12?qs=MxnWX8BLHKdYS1P2ecxOLA%3D%3D
08:13 PM Tom_L: 12v out

08:13 PM CaptHindsight: ^^ 9-36V IN, 12V out, 400W
08:14 PM Tom_L: o i c, now he's going _from_ 16.8
08:24 PM tiwake: CaptHindsight: see any good deals on a VF2 or VF3?
08:25 PM tiwake: or similar
08:33 PM _unreal_: ARG.... an hour of milling remaining
08:34 PM _unreal_: SOOO SLOW
08:36 PM Tom_itx: https://www.youtube.com/watch?v=F_w92CEMlT4
08:37 PM XXCoder: interesting
08:56 PM snakedGT is now known as snaked
08:59 PM CaptHindsight: Tom_itx: 16.8 to 10V DC IN, 12V out 20A
09:01 PM CaptHindsight: tiwake: ~$9k and up for either
09:08 PM flyback: https://www.foxnews.com/us/michigan-woman-suv-arson-explosion-arrest
09:09 PM CaptHindsight: botched suicide?
09:10 PM XXCoder: nah
09:10 PM XXCoder: if it was suicide she would be in vehicle
09:15 PM roycroft: never attribute to suicide what can be explained by mere stupidity
09:17 PM roycroft: adam's new shaper is huge
09:17 PM roycroft: 7-1/2 tons
09:17 PM roycroft: 60" stroke
09:18 PM roycroft: too big for his shop - he has to store it at a friend's until he can figure out where to put it
09:18 PM gregcnc: scrap yard?
09:18 PM * roycroft anticipates a series of videos about the new shop extension coming up soon
09:21 PM gregcnc: 7.5 tons will suck all the gravity out of his neighborhood
09:22 PM roycroft: he's in the florida panhandle
09:22 PM roycroft: it will just sink a little more
09:23 PM XXCoder: probably wouldnt be wise in few dcade late
09:23 PM XXCoder: *later
09:23 PM roycroft: there will be fewer florid man stories
09:24 PM roycroft: florida
09:24 PM XXCoder: nah there will be florida man forevermore
09:24 PM Rab: I bet you could rig a shaper into one of these: https://www.youtube.com/watch?v=KxaWvJ-ziXA
09:25 PM XXCoder: one of mountains should turn to island. thats where florida man will be at
10:14 PM skunkworks: That shaper would be cool to cnc...
10:17 PM skunkworks: I guess I would call it a planer...
10:25 PM _unreal_: ?
10:25 PM _unreal_: florida man?
10:33 PM roycroft: what would be the point of cnc'ing a shaper?
10:33 PM XXCoder: so you can use shaper to make a cnc of course
10:33 PM roycroft: it already runs on auto-pilot
10:34 PM Tom_L: skunkworks, et al.. i grabbed a couple pdfs on gears in case anyone is interested i posted them: http://tom-itx.no-ip.biz:81/~webpage/cnc/Gear_info/
10:35 PM roycroft: you set the stroke length, stroke speed, depth of cut, and step interval, turn it on, and let it do its thing
10:35 PM roycroft: maybe that's why abom likes them so much
10:35 PM roycroft: he can stand around and drink beer while it's doing the work
10:35 PM Tom_L: anybody with a cnc can do that!
10:38 PM roycroft: i had a good day
10:38 PM Tom_L: mine was ok
10:38 PM roycroft: i cut a couple threads with a single point tool and they are nice and tight
10:39 PM roycroft: almost perfect
10:39 PM Tom_L: mill or lathe?
10:39 PM roycroft: lathe
10:39 PM Tom_L: oh that 7/16 thing
10:39 PM roycroft: yes
10:39 PM roycroft: the rod i got was a little rough
10:39 PM roycroft: i needed 20" lengths for my project
10:40 PM roycroft: i ended up doing the machining, then i stuck 10" out of the chuck, hit it with a file lightly, and then polished it with a scotch brite pad
10:40 PM roycroft: reversed it and did the other half
10:40 PM roycroft: they turned out pretty nice
10:41 PM roycroft: far from a perfect finish, but these are for a jig i'm making, not for parts that people will see
10:41 PM roycroft: i just needed smooth and accurate, not pretty
10:41 PM _unreal_: arg.... so many holes in this plate
10:41 PM Tom_L: hehe
10:41 PM roycroft: choices are good, _unreal_
10:41 PM _unreal_: got 20 mounting holes prob over kill
10:41 PM roycroft: many holes means many choices
10:41 PM Tom_L: _unreal_, when i did mine, it was confusing which ones to counterbore on which side
10:42 PM _unreal_: I'll have to hand drill/tap all of the MOFO's
10:42 PM Tom_L: wax on... wax off...
10:43 PM skunkworks: if we are talking about aboms latest video - I thought that was called planer.
10:43 PM _unreal_: and these are just the mounting holes for the entire plate. I then have to drill the mounting holes for the rails that mount to the plate.
10:43 PM XXCoder: wonder if can use shaper as super polishing machine
10:43 PM XXCoder: set it leave it overnight just polishing metal
10:43 PM roycroft: it's a shaper, skunkworks
10:44 PM _unreal_: Its going to be amazing to be able to mill fast when I get the new spindle mounted
10:44 PM _unreal_: or at least so I think/hope
10:44 PM Tom_L: should be an improvement
10:44 PM _unreal_: mainly just the rigidity alone
10:45 PM roycroft: a shaper has a moving tool
10:45 PM roycroft: a planer has a moving part
10:45 PM roycroft: in the machining world
10:45 PM _unreal_: I loose so much on hard materails I have to have huge allowances so I can do finishing passes
10:46 PM roycroft: and actually, the part moves in a shaper too
10:46 PM roycroft: but not as part of the cutting stroke
10:46 PM _unreal_: I'm very pleased I discovered that I had missed adding some aspects to the base part. like limit blocks and limit switch mount locations
10:46 PM _unreal_: limit block HARD stop
11:19 PM skunkworks: roycroft: doesn't the part move on the shaper in his latest video? the table moves.
11:20 PM skunkworks: not the head
11:25 PM roycroft: not during the power stroke
11:26 PM roycroft: the table moves laterally between strokes
11:27 PM roycroft: so i'm making a jig where some components move along some steel rods, and need to be secured when they are positioned
11:27 PM roycroft: i'll be securing them with set screws
11:28 PM roycroft: i would prefer not to gall the steel rods though
11:28 PM roycroft: my choices are nylon tipped steel set screws and brass set screws
11:28 PM roycroft: i'm not sure which would be best
11:29 PM roycroft: i've used the nylon ones before, and they work well, but i'm concerned they might move a bit from the forces of the machine
11:29 PM * skunkworks doesn't understand I guess
11:29 PM roycroft: i want something softer than steel so it won't dig into the rods
11:30 PM roycroft: but i want it to still grip the rod securely
11:30 PM skunkworks: https://www.youtube.com/watch?v=NKfVmroKcTI
11:30 PM skunkworks: same thing - they call it a planer
11:30 PM roycroft: yes, that is a planer
11:31 PM roycroft: on the cutting stroke, the tool does not move
11:31 PM roycroft: the table moves
11:31 PM roycroft: aah, that looks like abom's new one
11:31 PM roycroft: i see what you're getting at
11:31 PM roycroft: abom is calling it a shaper
11:31 PM roycroft: and i did not pay enough attention to the video
11:31 PM skunkworks: Ok - I am not going crazy then ;)
11:32 PM roycroft: if that rockford is the same thing then abom is wrong
11:32 PM roycroft: sorry
11:32 PM roycroft: i was doing something else while watching his video
11:32 PM skunkworks: one of those would be fun to cnc. We had a closed planer - but it was too warn out.
11:32 PM roycroft: kind of half paying attention to the unloading
11:33 PM roycroft: the two shapers he has in his shop now are definitely shapers
11:33 PM skunkworks: heh - that is ok.
11:33 PM skunkworks: Yes - those are.
11:33 PM roycroft: but if his new rockford is the same as what you linked to that's definitely a planer
11:34 PM roycroft: i can't be bothered to watch his sns again
11:34 PM roycroft: so i'll take your word that it's the same thing, and that abom is wrong
11:34 PM roycroft: besides, i like the idea of abom being wrong once in a while
11:36 PM * roycroft doesn't trust people who are always right
11:36 PM skunkworks: it might be that is what they offically called it for some reason... but not what I would consider a planer
11:36 PM skunkworks: maybe he considers anyting with a clapper box a shaper
11:36 PM roycroft: maybe
11:36 PM roycroft: but my understanding is pretty clear, and i think it's correct
11:37 PM roycroft: on a shaper the cutter moves
11:37 PM roycroft: on a planer the part moves
11:38 PM skunkworks: sure
11:38 PM roycroft: and the part does a lot of moving on that rockford in the video you linked
11:38 PM skunkworks: someone ask the same question in the comments. no reply yet
11:39 PM roycroft: perhaps abom needs to finish his crow dinner before he can respond :)
11:57 PM jymmmm: PCB Factory tour... https://www.youtube.com/watch?v=ljOoGyCso8s
