#linuxcnc Calendar

12:59 PM Tom_L: gregcnc, machine shops are loud.
01:05 PM Tom_L: but yeah maybe
01:05 PM Tom_L: i also looked for VVVV belts but they don't make them that small
02:23 PM -!- #linuxcnc mode set to +v by ChanServ
02:54 PM gregcnc: check out this guys pseudo sliding head stock machine https://www.youtube.com/watch?v=5JYYwJ1LD1Q
02:59 PM andypugh: It’s cool, but I don’t understand the penultimate operation.
03:14 PM FinboySlick: So they're 'feeding' by moving the bed closer to the chuck?
03:16 PM gregcnc: yes
03:16 PM FinboySlick: Pretty clever.
03:19 PM FinboySlick: https://www.youtube.com/watch?v=NfMB88KalsY
03:19 PM W1N9Zr0: are those screws for fixing bones with plates?
03:20 PM W1N9Zr0: odd thing to DIY
03:21 PM FinboySlick: In post-soviet Russia, the surgery fixes you?
03:28 PM JT-Shop: Tom_L, no, been fighting with 15" of fence or rather a post that was not plumb
03:32 PM Tom_L: JT-Shop, http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/
03:32 PM Tom_L: https://www.youtube.com/watch?v=EH8EcwVvngg
03:38 PM JT-Shop: looking good, no sound on this pc
03:40 PM Deejay: gn8
04:55 PM skunkworks: one strut replaced...
04:55 PM skunkworks: way better..
04:58 PM XXCoder: tom nice
04:59 PM Tom_L: internal brake resistor gets hotter than a mofo but the external one is cool after several full power stops
05:00 PM Tom_L: ironically the internal one is 3x the physical size
05:04 PM roycroft: if anyone sees _unreal, there's a good price on gecko drives right now - it might be worth getting drives that are not prone to blowing up
05:04 PM roycroft: https://www.ebay.com/i/331739467415
05:14 PM CaptHindsight: roycroft: nahh, he seems to have some other plan
05:57 PM jdh__: $25 leadshine would be fine
05:58 PM roycroft: that's what he has, and he's had issues with magic smoke escaping
05:59 PM jdh__: prob him, not the driver then
05:59 PM roycroft: yes
05:59 PM roycroft: and he's admitted that
05:59 PM roycroft: gecko are a bit more user-tolerant
06:00 PM jdh__: deep down, I know it costs a lot more to buy cheap. but, I still end up doing it.
06:00 PM roycroft: some do it by necessity
06:00 PM roycroft: some by conviction
06:00 PM Tom_L: i have never regretted that purchase
06:00 PM roycroft: some merely because of ignorance
06:03 PM CaptHindsight: some don't learn the hard way
06:09 PM jdh__: that would be me.
07:08 PM XXCoder: interesting. im pretty stupid on electrics but i didnt release any magic smoke on my cnc machine stuff
07:09 PM XXCoder: ironically it may be because im not knowledgable, i look closer to setups.
07:14 PM jdh__: don't connect/disconnect motors from cheap steppers when they are powered. pretty much all I ever worry about
07:16 PM XXCoder: you mean drivers?
07:17 PM roycroft: gecko advise not disconnecting motors from their drivers while powered
07:18 PM jdh__: yeah
07:18 PM roycroft: i'm still not 100% certain what i'm going to turn off where when i install my e-stop switch, but i'm pretty sure i'm ging to kill power to the 48vdc power supply
07:18 PM roycroft: although it will still leak current for a short while
07:18 PM roycroft: so i'll probably kill power to the gecko drives as well
07:18 PM XXCoder: you can also turn some ON
07:19 PM XXCoder: locking steppers for one
07:19 PM XXCoder: overriding driver signals
07:19 PM XXCoder: not too sure how setup would look like but it was something i looked into a bit
07:19 PM roycroft: i'll look into it as well
07:20 PM XXCoder: ya thats why button has 2 sets
07:20 PM roycroft: the ideal e-stop behavior would be that everything that moves stops instantly
07:20 PM XXCoder: group to cut off, and group to enable
07:20 PM roycroft: and that nothing gets damaged because of the instant stop
07:20 PM XXCoder: yeah i was wondering about feedback if you override drivers and it stops instantly
07:21 PM roycroft: i'm not sure what will happen if i kill power to the 7i76
07:21 PM roycroft: i don't think anything will be damaged
07:22 PM roycroft: i'm just not sure what linuxcnc would think about it
07:24 PM roycroft: my current thinking is to kill power to the controller box and the motor power supply
07:25 PM roycroft: that would kill power to the gecko drivers and the 7i76
07:25 PM roycroft: leaving the pendant and console powered, as well as the linuxcnc machine, of course
07:25 PM roycroft: there would be no reason to ever kill power to that
07:26 PM XXCoder: cut drivers and power all steppers?
07:29 PM roycroft: i don't need to turn off the linuxcnc machine to do that
07:29 PM roycroft: the controller is its own separate enclosure
07:30 PM roycroft: and the motor power supply is stand-alone
07:30 PM roycroft: but i'll power it from the controller
07:40 PM jdh__: who makes good PLA
07:41 PM roycroft: as in filament for 3d printing pla?
07:41 PM jdh__: yes
07:41 PM skunkworks: hatchbox? I really don't knw
07:41 PM roycroft: https://atomicfilament.com
07:41 PM roycroft: i'm not a 3d printing expert by any means
07:41 PM roycroft: but i really like their filament
07:42 PM roycroft: and it's made in usa
07:42 PM roycroft: and very reasonably priced, with fast, free shipping
07:42 PM roycroft: i usually get it in 2 days
07:42 PM CaptHindsight: http://www.zyltech.com/
07:43 PM roycroft: there's been a filament shortage since the beginning of the pandemic
07:43 PM jdh__: not on amazon
07:43 PM roycroft: it seems that everyone who lost their job sits at home pringing masks these days
07:43 PM roycroft: printing
07:44 PM roycroft: i've not used zyltech
07:45 PM roycroft: their pla is $10 cheaper than atomic filament's
07:45 PM roycroft: but do they ship for free?
07:46 PM andypugh: skunkworks: I got really close to using your polygonal boring stuffs in anger this week. I had some double-D holes to make for GX12 connectors, and realised that I could make a punch and die that way. But then I decided that just drilling then filing the holes would be faster.
07:46 PM CaptHindsight: roycroft: not sure, I make their resin
07:47 PM roycroft: they sell pla for $21.95 one ebay with free shipping
07:48 PM roycroft: a double d punch and die is pretty expensive to buy ready-made
07:49 PM roycroft: i figure once i have a cnc mill i can cut double d openings with that, and just file the corners
07:50 PM roycroft: it's turing into winter fast here
07:50 PM roycroft: it was 25 degrees just a couple days ago
07:51 PM roycroft: it got up to 18 early today, but was down to 10 well before sundown
07:51 PM roycroft: it will probably get down to 2 or 3 tonight
07:52 PM roycroft: yeah, and we'll go below freezing on sunday morning
07:54 PM CaptHindsight: i think i saw a storm heading for the Pacific Northwest
07:54 PM CaptHindsight: roycroft: seems like half the people I know from Chicago before 1990 have moved out west
07:56 PM roycroft: yes, it's a common migration path
07:56 PM CaptHindsight: i know of very few that still live in the city
07:56 PM CaptHindsight: they at least move to the burbs
07:58 PM roycroft: the wind is from the north northwest tonight
07:58 PM roycroft: so we're getting some cold air from alaska/siberia
08:02 PM skunkworks: andypugh: aww... You could have been more angry trying to get it to work :)
08:02 PM roycroft: actually, there's a big high pressure system centered almsost due west of eugene and south of anchorage that's slowly circulating clockwise
08:03 PM roycroft: and the wind is westerly up to the southern edge of the gulf of alasks
08:03 PM roycroft: alaska
08:03 PM roycroft: so we're not getting any arctic air
08:03 PM roycroft: but it's still getting cold
08:03 PM roycroft: there will be snow in the mountain passes tonight
08:08 PM andypugh: skunkworks: It really is a genuine use for the technique. And D-flat holes are really common in electronics. Google will show you many questions along the lines of “how do I make this hole”
08:09 PM skunkworks: sure - there was a thread on practical machinist that someone resurrected and pointed to my method.
08:10 PM andypugh: Punch and die is the answer, but how to make the die?
08:11 PM skunkworks: the file was mentioned a lot. :)
08:11 PM roycroft: a double d punch and die use a double d alignment rod, don't they?
08:12 PM skunkworks: andypugh: did you see my hack solution for making any shape? (within tooling reason)?
08:12 PM skunkworks: andypugh: https://www.youtube.com/watch?v=-4sKHBh6rDk
08:12 PM andypugh: Yes, but I didn’t investigate in detail.
08:12 PM skunkworks: now only limited by imagination... ;)
08:13 PM skunkworks: tldr - use a gcode shape to 'scan' into the componant.
08:21 PM andypugh: Aye, I saw that, but reckoned that it would take me longer to understand it than to modify 6 holes :-)
08:24 PM skunkworks: yep :)
08:30 PM roycroft: my favorite video of the week - a young, classically trained flutist discovers jethro tull and streams her reaction to an ian anderson solo:
08:30 PM roycroft: https://www.youtube.com/watch?v=gKSrq_qjB_Y
08:30 PM andypugh: Aye, I watched a bunch of those.
08:31 PM roycroft: she was pretty blown away
08:32 PM andypugh: I think he was (is?) self-taught so did it all a bit differently
08:33 PM roycroft: it's easier to break the rules if you don't know them
08:33 PM roycroft: and ian anderson is still with us
08:34 PM roycroft: i've seen jethro tull several times, and i think my favorite show was in vancouver, bc in the late '80s/early '90s - i forget exactly when it was
08:34 PM roycroft: but was at a small theatre, and the stage was set like a living room
08:35 PM roycroft: throughout the concert ian would go out in the audience, get a person or a couple, and brought them up on the stage to sit on the sofa while he played for them
08:36 PM andypugh: The best gig I ever went to was Uriah Heep in Halifax to a “crowd” of 50. One ot their original members dies this week.
08:37 PM andypugh: But they just went all out on the performance, but made it more personal. They really didn’t seem to care that the venue was empty. And I have never seen any band “run” an audience to well.
08:42 PM roycroft: nice
08:42 PM roycroft: the most pathetic show i ever went to was to see the english beat
08:43 PM roycroft: it was in a small venue, and it was about 15 years ago, when they were well past their prime
08:43 PM roycroft: but there were only a half dozen people there
08:43 PM roycroft: and when the band came out and saw the venue was empty, they were pretty dejected
08:43 PM roycroft: but they put on a show anyway
08:44 PM andypugh: That video you linked hits so many boxes, Jethro Tull being brilliant, cute Finnish(?) girl a a “reaction video” where the creator is genuiniely surprised.
08:45 PM roycroft: i really liked it
08:46 PM roycroft: and it was definitely a real reaction video
08:46 PM roycroft: not staged
08:46 PM andypugh: So did I, and I think she did a couple more. I think it opened her eyes to what a flute could do.
08:46 PM roycroft: yes
08:46 PM roycroft: the thick as a brick one was really good
08:47 PM roycroft: especially when she says "i never tried that!"
08:48 PM roycroft: i wonder if she's aware that the bagpipe is fingered much like ian anderson fingers the flute - with the fingers flat, and with the second joint covering the holes, not the tips
08:48 PM roycroft: and i wonder if ian anderson ever played the bagpipe
08:53 PM andypugh: Oh, by the way, congrats USA on making a fascinating “who will be president” game show last so long ;-)
08:53 PM andypugh: We are all hooked on it over here.
08:53 PM XXCoder: it must be slowest end of presidency confirm ever
08:53 PM jdh__: USA Reality TV
08:55 PM andypugh: If I was Trump I would be convinced of fraud too, to be fair. I have never seen an election swing late this way before.
08:56 PM andypugh: But I am not him, and can see how the circumsances would lead to there being many more D postal votes than R
08:56 PM XXCoder: yeah and timing
08:56 PM XXCoder: most states counted in person first
08:56 PM XXCoder: then mail in
08:57 PM andypugh: Yes. But it is definitely unusual.
08:57 PM XXCoder: theres big polarization between those 2. thats why trump worked on whecking usps as well as try push "mail in is fraud"
08:57 PM XXCoder: i cant wait for him to be finally irrevelant
08:58 PM XXCoder: on agenda of "mail in is fraud" they showed guy writing on new ballots at table
08:58 PM andypugh: In the UK there are no interim results. Just one announcement when the count is complested. (And after a recount if the candidates request one, I think)
08:58 PM XXCoder: but reality is that hes sitting opposite guy reading damaged ballot so it can be counted
08:59 PM XXCoder: along qith watchers around to ensure vote isnt changed
08:59 PM XXCoder: i wish 24 hours blackout on news
08:59 PM XXCoder: trhat way west side of usa isnt affected by east results at start
08:59 PM XXCoder: because some people just want to be winner and dont care otherwise
09:01 PM andypugh: In the UK we typically have a good idea by 4am and know for sure by the next morning. But I guess your ballots have further to travel,
09:01 PM XXCoder: not really they are counted in one area
09:02 PM XXCoder: (each state county)
09:02 PM andypugh: Some constituencies compete to be first, and get the result out inside an hour of polls closing.
09:04 PM XXCoder: geez. i rather have accurate than sooner
09:08 PM roycroft: it's easy to be both, xxcoder
09:08 PM roycroft: the uk have a very simple system of counting votes
09:08 PM XXCoder: yeah but then competiting makes it questionable a little
09:08 PM roycroft: they take the ballots and put them in piles
09:08 PM XXCoder: they throw em away and roll dice?
09:08 PM roycroft: one pile for each candidate
09:09 PM roycroft: and then they count the piles
09:09 PM roycroft: the uk also does not have the electoral college mess that we have
09:09 PM XXCoder: i wish we dont
09:09 PM XXCoder: its really time to remove it.
09:09 PM roycroft: however
09:10 PM jdh__: will never happen
09:10 PM XXCoder: biden has 4 million votes + and there is still slight chance electors screw him
09:10 PM roycroft: the uk, and most countries with parliamentary forms of government, have a true multi-party system
09:10 PM roycroft: so although the results of the election are known almost immediately, as in how many mps each party won, who will form a government does not always happen immediately
09:11 PM roycroft: in the uk it usually happens fairly quickly these days
09:11 PM roycroft: in places like the netherlands it can take months
09:11 PM roycroft: in isreal it can take years, and multiple elections
09:13 PM roycroft: the electoral college would be very hard to get rid of
09:14 PM jdh__: impossible
09:14 PM roycroft: not impossible
09:14 PM roycroft: but very hard
09:14 PM roycroft: it can be effectively avoided a lot more easily
09:14 PM XXCoder: what we need more is ranked voting
09:14 PM roycroft: and scotus just made it a lot easier
09:15 PM XXCoder: so we can vote what we want, then backup choice
09:15 PM roycroft: yes, xxcoder, that's exactly what we need
09:15 PM XXCoder: rather than get best possible out of 2
09:15 PM roycroft: it's the single biggest reform that could make to improve things
09:15 PM roycroft: and it's being done, slowly
09:15 PM XXCoder: republicans and democrats both needs other people be able to worry them so they listen to people more
09:15 PM XXCoder: democrats generally do better on that but not always
09:16 PM jdh__: it would require 2/3 of house and senate for amendment. and would negatively impact > 1/3 of them
09:17 PM roycroft: yes, but the national popular vote movement could avoid the electoral college effecively
09:17 PM roycroft: and that would not involve the congress at all
09:18 PM roycroft: the hard thing about an amendment, btw, is not the congress
09:18 PM roycroft: it's the 3/4 of the states that have to ratify it
09:18 PM roycroft: making that avenue even more difficlt
09:18 PM roycroft: but the national popular vote movement only requires 270 electors worth of states passing it
09:18 PM roycroft: and they're over halfway there already
09:19 PM roycroft: my state signed on last year
09:20 PM XXCoder: sounds like twitter plan to instantly ban trump once he leaves office
09:21 PM XXCoder: no more cloak of presidency
09:21 PM roycroft: steve bannon was banned for life today
09:21 PM XXCoder: yeah
09:22 PM roycroft: calling for the behading of dr. fauci was too much even for twitter
09:22 PM roycroft: beheading
09:22 PM XXCoder: rumors tho. nothing hard
09:23 PM roycroft: the county just to the north of me was the first part of oregon to use preference voting
09:23 PM roycroft: for county lesser races
09:23 PM roycroft: county and lesser
09:23 PM XXCoder: its a start
09:23 PM roycroft: hopefully the state will implement it soon
09:23 PM roycroft: our newly-elected secretary of state is a strong advocate of preference voting
09:26 PM Tom_itx: https://www.youtube.com/watch?v=rX4eP3QLwo0&feature=youtu.be
09:27 PM Tom_L: the scale is off
09:27 PM XXCoder: wb
09:27 PM XXCoder: encoder second belt?
09:27 PM Tom_L: yeah
09:28 PM Tom_L: not for spindle control, not yet anyway
09:28 PM XXCoder: does it being slightlu less than tight is fine?
09:28 PM Tom_L: yeah
09:28 PM andypugh: The UK has very nearly your electoral college system.
09:29 PM roycroft: well, i suppose
09:29 PM roycroft: but there is exactly one elector - god
09:29 PM roycroft: and once the chosen, the job is hereditary
09:29 PM andypugh: If we clumped constuencies by county, and reported by county, it would be the same
09:30 PM XXCoder: any unfaithful issues?
09:30 PM Tom_L: XXCoder, i don't wanna over stress those tiny bearings
09:30 PM XXCoder: makes sense. usually tiny arc error dont affect rpm and position all that much
09:31 PM Tom_L: i do think i need to run the analog back thru the PID though
09:31 PM Tom_L: the scale is off
09:31 PM XXCoder: rpm or also plan positional?
09:31 PM Tom_L: rpm
09:32 PM XXCoder: nice
09:32 PM XXCoder: i added 2 magnets to my spindle fan for rpm also
09:32 PM andypugh: roycroft: Ah, well, yes, for Head of State we choose the emminently sensible approach of the eldest heir of someone who was good at fighting several centuries ago,
09:32 PM XXCoder: sensor sucked so i planned to upgrade sensor but then i moved and no room lol
09:32 PM roycroft: until very recently, the eldest mae heir
09:33 PM roycroft: male
09:33 PM andypugh: roycroft: Queen Elizabeth I wasn’t _that_ recent
09:34 PM roycroft: she was the default when they ran out of men
09:35 PM roycroft: edward vi did not last very long
09:35 PM roycroft: and he was henry viii's only surviving male issue
09:35 PM Tom_L: XXCoder, i stripped out all the spindle code and am gradually adding it back in. i didn't want any surprises
09:35 PM roycroft: unless you want to count that fitzroy lad
09:35 PM roycroft: which some still do
09:36 PM XXCoder: tom smart.
09:37 PM andypugh: roycroft: True, QE1 could have been trumped by a younger brother.
09:38 PM roycroft: that was only changed a few years ago
09:38 PM roycroft: but does not apply to the current royal family, i believe
09:38 PM andypugh: And one would assume that any “Fitzroy” has a claim, as he surname is lierally “Illegitmate son of the king”
09:38 PM roycroft: yes
09:39 PM roycroft: that's how he got his name
09:40 PM andypugh: I guess “Fitzreigne” doesn’t happen?
09:40 PM roycroft: anyway, i think the new succession of first born, not first male born, applies to prince george's issue, and not before
09:41 PM roycroft: i don't know
09:42 PM roycroft: it would be intersting if she had a child with robert dudley
09:42 PM roycroft: elizabeth i, that is
09:43 PM andypugh: Well, any issue of a ruling Queen would have no doubt of who their mother was, and legitimacy (logicaly?) wouldn’t count?
09:43 PM roycroft: there was a pretender claiming to be exatly that
09:43 PM roycroft: exactly
09:43 PM roycroft: but he was sent to spain
09:43 PM roycroft: never to return
09:43 PM roycroft: i'm sure because he was smart enough to know not to return
09:44 PM andypugh: Makes no sense. QE1, had she birthed an heir could just have claimed it.
09:45 PM andypugh: Why _wouldn’t_ she?
09:45 PM roycroft: because she was a virgin
09:45 PM roycroft: and a protestant
09:45 PM roycroft: a virgin birth would be considered rather catholic :)
09:45 PM XXCoder: well if dead bodies of them can be tested for family relations
09:45 PM roycroft: um
09:45 PM roycroft: i mean
09:45 PM andypugh: Being Queen trumps all that.
09:45 PM roycroft: she was a "virgin"
09:46 PM roycroft: i'm not sure what became of arthur dudley
09:46 PM roycroft: he had some menial position with the spanish royal house
09:47 PM roycroft: his remains may be long lost
09:47 PM andypugh: https://en.wikipedia.org/wiki/Arthur_Dudley
09:47 PM roycroft: and i'm sure the current royal family would not want to stir that can of worms up again
09:48 PM roycroft: were it proven to be true one of dudley's heirs could make a claim to the throne
09:48 PM andypugh: OK, so |In 1561, she was mysteriously bedridden with an illness that caused her body to swell.” https://en.wikipedia.org/wiki/Arthur_Dudley
09:49 PM andypugh: The _current_ Royal family wouldn’t care. They were imported.
09:50 PM roycroft: so from that article it seems that arthur dudley was disappeared
09:50 PM andypugh: (so don’t need to claim descent from the Tudors, and in fact have none)
09:50 PM roycroft: and when royals disappear someone, that makes it extremely difficult half a millinium later to exhume the body and do some dna testing on the remains
09:51 PM roycroft: this is true, but that was well post the tudor era
09:51 PM roycroft: a completely alternate line of succession could, and probably has been, created
09:52 PM roycroft: the saxe-coburg and gotha house may never have been legitimate
09:54 PM Tom_L: where's pcw been lately?
09:55 PM CaptHindsight: he's been on the ML
09:56 PM CaptHindsight: it's no fun here anymore
09:57 PM roycroft: i finally got my cyclone pre-separator installed and tested tody
09:57 PM roycroft: for my dust collector
09:57 PM roycroft: it works pretty well
09:57 PM roycroft: and i have it choked down right now, because i don't have the correct size ducting for it yet
09:58 PM roycroft: the barrel i picked up for it the other day works brilliantly - it seals very tightly
09:59 PM Tom_L: JT-Cave, just for you: https://www.youtube.com/watch?v=czZrpFbY8DA
09:59 PM CaptHindsight: there is a current mini-series about Catherine of Aragon
09:59 PM CaptHindsight: but they don't stick to history
10:00 PM Tom_L: let's just rewrite history
10:00 PM Tom_L: it didn't really happen anyway
10:01 PM roycroft: donut mess with momma
10:01 PM roycroft: i've head about that, capthindsight
10:01 PM roycroft: but i haven't bothered to find out more about it
10:02 PM roycroft: unfortuantely we do way too much rewriting of history
10:02 PM CaptHindsight: https://en.wikipedia.org/wiki/The_Spanish_Princess
10:03 PM CaptHindsight: there was plenty of historical drama to work with, not sure why they felt the need to just drift off at times
10:03 PM roycroft: sometimes it's laziness
10:03 PM roycroft: sometimes the ego of the screenwriter
10:04 PM roycroft: sometimes just a bad attitude
10:05 PM CaptHindsight: the current episode covers an outbreak of the plague ~1516
10:05 PM CaptHindsight: the TV guide by eldiario.es both call it "one of the worst shows about Spanish history."
10:06 PM CaptHindsight: has been described by various media as "insulting", "offensive", and "as full of stereotyping as sadly expected".
10:06 PM CaptHindsight: to put it mildly
10:06 PM roycroft: sounds entertaining
10:11 PM andypugh: Blackadder I and the Infanta of Spain was hilarious.
10:13 PM roycroft: yes
10:13 PM roycroft: all of blackadder was hilarious
10:13 PM roycroft: but that was particularly so
10:13 PM andypugh: (Well, mainly the unemotional translator saying, in a pitch-black screen “My daarling my daaring, my loove, my loove, now we are alone together”
10:14 PM roycroft: my two favorite episodes were the one with his parents and the turnip, and the scottish play
10:15 PM andypugh: A friiend of mine talks of “the Scottish food”
10:16 PM andypugh: If you say “Porridge” he replies with “Mention not the name of the Socttish food”
10:17 PM andypugh: This was especially fun as he used to cater a group breakfast on the way to Brighton every year. Featuring deep-fried “Scottish food”
10:18 PM roycroft: but does he have a ritual for when it is mentioned?
10:19 PM roycroft: speaking of scottish food
10:19 PM roycroft: st andrew's day is the end of the month
10:19 PM andypugh: Not that I recall.
10:19 PM roycroft: i usually make some scottish food for that
10:20 PM roycroft: and piss off my redneck neighbors by displaying a saltire
10:20 PM roycroft: they don't know what kind of flag that is, but they know it's not 'mericun
10:21 PM roycroft: i only do it twice/year - on st. andrews day and on burns night
10:21 PM andypugh: The Hawaiin flag is a curiosity
10:21 PM roycroft: yes
10:25 PM andypugh: Most especialy as it changed when the Union Flag changed.
10:26 PM XXCoder: tlking about flags
10:26 PM XXCoder: one state removed bars from flag
10:26 PM XXCoder: mississpi
10:32 PM skunkworks: Tom_L: that is how I remember the drives that came with the spindle on the green machine - overshoot when finding the rpm..
10:32 PM roycroft: yes
10:32 PM roycroft: mississippi was the last state with a confederate-ish flag on their flag
10:33 PM roycroft: now there's a blooming magnolia
10:33 PM roycroft: and it's a much more attractive flg
10:34 PM andypugh: Fun With Flahs
10:34 PM XXCoder: JT-Shop: interesting video
10:34 PM andypugh: (Flags)
10:34 PM XXCoder: yeah i like the look of new one
10:34 PM XXCoder: ignoring old flag history
10:35 PM andypugh: I disagree. Flags should be geometric, not pictorial.
10:36 PM roycroft: historically they needed to be
10:36 PM roycroft: they had to be easy to recognise from a distance on the battlefield
10:36 PM XXCoder: usa flag is amazing complex for era it was come up with
10:36 PM XXCoder: adding stars just made it more complex
10:37 PM roycroft: from a design point of view, ours is far from the most attactive national flag
10:37 PM veegee: Any ideas for what I could use as a wheel for a DIY belt sander build?
10:37 PM andypugh: I prefer the three-stripe flags.
10:37 PM veegee: Example: https://www.youtube.com/watch?v=uHBlnSMx604
10:37 PM veegee: Not sure where he got those wheels from, they look strange
10:38 PM veegee: Old forklift cushion tire wheels are a possibility seeing as there's a broken down forklift with good wheels sitting outside
10:38 PM XXCoder: might be
10:38 PM veegee: they'd also make for a huge flywheel
10:39 PM veegee: the kinetic energy of a forklift wheel spinning at 3,600 RPM lol
10:39 PM andypugh: The Union jack is odd. I don’t really like it as a flag, but as a design it has become wierdly popular. You see folk with it on clothes and bags all over the world, which is frankly a bit strange
10:40 PM roycroft: veegee - i got one like this for my belt grinder:
10:40 PM roycroft: https://www.ebay.com/itm//114366094286
10:40 PM roycroft: except i got a 10" one
10:40 PM roycroft: 12" would be too big for mine
10:40 PM veegee: oh wow perfect, thanks
10:40 PM roycroft: the union jack will be interesting when scotland leaves the union
10:41 PM roycroft: a serrated one runs a lot cooler than a solid one
10:41 PM roycroft: so do get a serrated one
10:41 PM roycroft: i got mine from that same seller
10:41 PM roycroft: and it's an excellent wheel
10:44 PM roycroft: https://www.ebay.com/itm/231396771664
10:44 PM roycroft: that guy makes nice drive wheels and idler wheels
10:44 PM roycroft: and he also makes small wheels and a small wheel holder
10:45 PM roycroft: i use his stuff on my machine
10:45 PM andypugh: I could make nice wheels at $45 each
10:45 PM roycroft: https://www.ebay.com/itm/233164003450
10:46 PM roycroft: that's a nice set of wheels if you're going to also have a platen
10:56 PM roycroft: mark meadows has covid-19
10:56 PM roycroft: and he attended the election night party at the white house with hundreds of people
10:59 PM CaptHindsight: i wonder how many times I've had it so far
11:00 PM roycroft: i look forward to a day when we no longer hear of how many new cases there are
11:00 PM roycroft: hopefully that day will come within the next year
11:00 PM CaptHindsight: I also wonder what people actually have that go for test with symptoms and get negative Covid results
11:01 PM roycroft: the seasonal flu, amongst other things
11:01 PM roycroft: we'll see a lot more of that soon
11:01 PM roycroft: but many get tested just to be tested
11:03 PM roycroft: i have no idea how many of the negative tests are for people who present symptoms vs. people who either just want to know or who think they were in contact with someone who has it
11:48 PM roycroft: bummer
11:48 PM roycroft: geoffrey palmer has died
