02:10 AM Deejay: moin
02:24 AM veegee: Deejay good morning to you sir
02:24 AM veegee: Deejay and happy 4th of July
04:27 AM XXCoder: interesting. https://www.youtube.com/watch?v=wZ7WcFxSc6I
05:06 AM JT-Cave: morning
05:06 AM XXCoder: yo
05:06 AM XXCoder: jt that little knee mill is interesting
05:06 AM XXCoder: but i dont think i will build it. too bad lol
05:17 AM JT-Cave: looks like junk to me
05:17 AM XXCoder: same to me, but then im used to large cnc machines
05:17 AM XXCoder: it might be good enough for home hobbyist
06:36 AM JT-Cave: package to canada went to st louis, springfield il, aurora il, chicago then miami!
06:37 AM XXCoder: geez
06:40 AM JT-Cave: I had one package to austria that went to the bahamas and finally made it to austria after 3 months but they didn't call the guy and sent it back to me total travel time 5 months
06:40 AM XXCoder: i remember reading about a guy package that "orbited" his home city for weeks
06:41 AM XXCoder: 2 cities to west and to east of that city kep [passing that package around over and over
06:42 AM XXCoder: some shipping is just ricious :(
06:43 AM JT-Cave: aye
06:44 AM XXCoder: my own experence worse one was one from new york to vancouver
06:44 AM XXCoder: it was 6 months.
06:47 AM XXCoder: unknown why it took so long
06:47 AM XXCoder: normally it'd be 3 days, because vancouver is near major shipping center, so are new york
06:52 AM JT-Cave: that's crazy
06:53 AM XXCoder: yeah
06:53 AM XXCoder: my best guess, it fell off converyers and was dusty by time someone found it
06:53 AM XXCoder: it was quite a while ago, before tracking is more common
07:10 AM JT-Cave: the almost good news is the 3 packages stuck in japan for a few weeks finally got a flight down under
07:40 AM enleth: veegee: a gundrill has one critical difference from a long boring bar
07:41 AM enleth: veegee: a boring bar touching the inside of the hole anywhere other than the cutting edge is a rubbing or crashed boring bar
07:41 AM enleth: a gun drill is made to deliberately bear on the hole opposite the cutting edge
07:42 AM enleth: and it will deepen blind holes
07:42 AM enleth: otheewise, the cutting action itself is similar to a boring bar
07:48 AM XXCoder: wb JT-Shop
07:48 AM XXCoder: JT-Cave: wb'
07:49 AM XXCoder: thats good that those 2 pckages is moving
08:16 AM JT-Cave: I'm glad all 4 packages are moving and I'll be glad when they get there even more. I don't use USPS international any more... UPS has their own planes
08:42 AM Tom_L: https://packageradar.com/courier/cainiao/status/soon_delivery/33440
08:42 AM Tom_L: :)
08:43 AM Tom_L: https://www.youtube.com/watch?v=zjdpz05u2DY
09:24 AM Tom_L: JT-Cave, is fedex higher than ups?
09:34 AM JT-Cave: dunno, I don't ship with fedex
11:11 AM Loetmichel: **meh** just had to pump a few cubic meters of "Light rain" out of our cellar... good thing i have a submersible pump at hand. why did i go to the cellar today at all?
11:25 AM Tom_L: anyone have a particular brand of drill bits they like?
11:38 AM cradek: I love the triumph twist drill 135 split points. I use screw machine length when possible.
11:39 AM Tom_L: yeah, i'm looking for a set of screw machine length
11:42 AM cradek: that's exactly what I have for the good stuff. I use a harbor fright set for drilling junk.
11:43 AM Tom_L: i've got a full set of regular length but now that i have a decent spindle motor want to start using them more on the cnc and the length is prohibitive on the larger sizes
11:44 AM cradek: inch? https://www.mscdirect.com/product/details/09581414
11:45 AM Tom_L: yes, number, letter, fraction
11:45 AM Tom_L: i'm on the travers site right now
11:46 AM cradek: it's gonna cost you, but you won't regret it after you've forgotten about the price :-/
11:46 AM Tom_L: i know what tooling costs :)
11:46 AM Tom_L: you either pay or you pray
11:47 AM cradek: yeah especially taps
11:47 AM Tom_L: especially the sizes you probably use
11:48 AM Tom_L: i'll check with my local guy. he was closed but i dunno if it was for the 4th or if he had another bout with cancer
11:49 AM Tom_L: small tool shop
11:50 AM cradek: aw, hope he's ok
11:51 AM cradek: the one here closed years ago.
12:16 PM JT-Cave: for taps I only use OSG Electralube
12:16 PM JT-Cave: they tap so easy and last a long time
01:34 PM Tom_L: yeah tap honey makes the world a great place to be
01:36 PM Tom_L: oh wait.. you're talking about a coating
02:13 PM JT-Shop: yep
02:15 PM Tom_L: did you jus start using those?
02:16 PM JT-Shop: been using them since 2003 or so
02:19 PM Tom_L: you gonna dust off the cannon this year?
02:20 PM JT-Shop: I should let one fly
02:21 PM JT-Shop: but Bambi is eating lunch right now
02:21 PM Tom_L: chickens might not appreciate it either
02:22 PM Tom_L: where was it you get your carbide bits? was it lakeshore or online carbide?
02:25 PM JT-Shop: carbide end mills from lakeshore
02:25 PM JT-Shop: drill bits from msc
02:26 PM Tom_L: i was looking at online carbide and they're a bit cheaper but i've never tried their endmills
02:26 PM Tom_L: same coating
02:28 PM Tom_L: have you tried lakeshore's chip breaker ones?
02:29 PM JT-Shop: no
02:29 PM Tom_L: just a little notch in the flute partway up
02:29 PM Tom_L: i haven't either
02:33 PM JT-Shop: I don't do any high performance machining, my machines are like me old and likes to take a nap now and then
02:33 PM Tom_L: hah, i hear that
02:34 PM Tom_L: i may try a couple of the online carbide ones
02:34 PM Tom_L: they're quite a bit less
02:40 PM JT-Shop: I havn't ordered an end mill in a few years, I'm sure one day I'll need to
02:40 PM Tom_L: i didn't have many so once the mill started working right now i need a few
02:48 PM JT-Shop: I used to keep a stock of all sizes for aluminum and steel when J&J Automation was blowing and going
02:59 PM _unreal_: trying to figure out what to do right now... hehe
02:59 PM _unreal_: dont have any projects
03:00 PM Tom_L: go to the beach and get bit by a jellyfish!
03:01 PM Tom_L: bit? stung?
03:01 PM _unreal_: did that yesterday
03:02 PM _unreal_: went to "rapids" and I went to the beach
04:30 PM JT-Shop: roycroft, what do you use to lubricate the posts on the planer?
04:44 PM roycroft: i just use boeshield - it is mainly a rest preventative, but it does libricate a little as well
04:44 PM roycroft: and they don't really need much
04:44 PM roycroft: rust, rather
04:44 PM JT-Shop: ok thanks, I have some of that... was planing some boards and noticed it was sticking a tad going down
04:44 PM JT-Shop: oh shoot I was going to spray some on me so I could get some rest
04:45 PM roycroft: if you use oil or something all it will do is collect sawdust and form a thick cake
04:45 PM JT-Shop: that's what I was sorta thinking
04:45 PM roycroft: well my new jig is working brilliantly
04:45 PM roycroft: the one to make the big arcs
04:46 PM roycroft: what i ended up doing is a variation on the two pins and a flexible rule thing
04:47 PM roycroft: i calculated the angle between the middle of the arc and the ends - it was 3.25 degrees - and i mitered the endsof two pieces of mdf at 1.625 degrees, joined them together with a biscuit and a lot of glue, then located two 1/4" pins at the endpoints of the arc on my template
04:48 PM JT-Shop: sweet
04:48 PM roycroft: i mounted a router on the joined mdf boards and cut the curve that way
04:48 PM roycroft: i had to make a mating piece as well
04:49 PM roycroft: so i cut the first piece with the router bit on the outside of the boards, touching the joint
04:49 PM roycroft: then i moved it back so it was on top of the boards, with the outer edge just touching the joint
04:49 PM roycroft: the two pieces came out perfect
04:50 PM roycroft: it was a fair amount of meticulous work, but still a lot easier than making a 13+ foot long pivot
05:00 PM CloudEvil: :)
05:05 PM _unreal_: I'm prob to late but getting ready to head down town for the fire work. (too late for good parking
05:09 PM veegee: roycroft hope you're enjoying your fourth of July :)
05:09 PM XXCoder: happy brexit 1776 day all!
05:10 PM JT-Shop: roycroft, glad you got that sorted out
05:10 PM JT-Shop: the planer is smooth again :)
05:10 PM * JT-Shop heads to the deck
06:24 PM roycroft: it's time for the operation that chewed up my first set of drawer pulls
06:24 PM roycroft: so i'll know soon if all the work on the jigs paid off
06:56 PM veegee: There are like a 100 auto repair shops within walking distance lol
06:56 PM veegee: Do they just throw out their old brake rotors?
06:56 PM veegee: Or do they keep them and sell them somehow?
06:57 PM veegee: What I'm getting at is, if I go door to door, are they likely to just give me their old brake rotors? Or perhaps even sell them for a low price?
06:57 PM veegee: I'm really loving the versatility of these things. They're easy to machine and make excellent bases for pretty much everything
06:57 PM veegee: And with proper preheating, they TIG weld just fine with the right filler
06:58 PM XXCoder: just be careful of abestos
06:58 PM veegee: XXCoder you mean traces left over from the brake pads?
06:58 PM XXCoder: yes
06:58 PM veegee: I thought they don't use asbestos anymore
06:58 PM XXCoder: its still legal in certain uses
06:59 PM Tom_L: cheap ones are
06:59 PM XXCoder: including brake pads
06:59 PM veegee: <3 you both
06:59 PM veegee: Thanks for the warning
06:59 PM veegee: I'll wear gloves and a P100 respirator until I can thoroughly clean them before machining
07:01 PM veegee: I am so damn excited to move my new vertical machining center in next week. Reorganizing the entire shop with new racks and such to make space for it
07:01 PM veegee: Not that it needs much space, but I want its home to be pretty
07:11 PM roycroft: wow, with the new jigs it seemed like i was doing a completely different operation to the identical one that i attempted with the original jigs
07:11 PM roycroft: the parts machined like cutting butter, instead of being spit out and chewed up and making me fear that i'm going to cut my fingers off
07:12 PM Tom_L: safety is a consideration when thinking of one's self
07:12 PM roycroft: one more set of machining operations, and then a whole lot of hand sandling/blending
07:12 PM roycroft: it should be a consideration when thinking about anyone
07:12 PM roycroft: but i was not anticipating the previous problems
07:12 PM roycroft: i set the jig up and machined some mdf samples just fine
07:12 PM veegee: except people who use imperial. Those people don't matter and are disposable
07:13 PM veegee: roycroft JUST KIDDING JUST KIDDING
07:13 PM roycroft: but when i tried doing the same thing to mahagony, it was a completely different story
07:13 PM roycroft: fuck off, veegee
07:13 PM * Tom_L slaps veegee with an american aligator
07:13 PM roycroft: you can't be an asshole and then say "just kidding"
07:13 PM veegee: are you telling me you don't understand the concept of a joke?
07:13 PM roycroft: and no worries, channel, that's all i have to say to or about that cretin today
07:14 PM Tom_L: veegee, don't push your bounds here
07:14 PM veegee: Because it was just a joke.
07:15 PM veegee: roycroft no need to be vulgar and rude, you're better than that man
07:15 PM roycroft: when i originally made these parts i sanded the curves freehand, as darrel peart suggests
07:16 PM roycroft: not only were they uneven, contributing to the problems i experienced before, it took me a lot longer than using the router jig i made
07:16 PM roycroft: like about 5x longer
07:16 PM roycroft: so the investment in time and money in the jig is really paying off
07:19 PM veegee: Tom_L why not a crocodile?
07:19 PM veegee: Do they prefer metric?
07:19 PM roycroft: the really fun part hasn't begun yet - making mahagony look like it's not an open pore wood, and making wenge look like ebony
07:19 PM _unreal_: tried to go out for fireworks. just got back said FUCK IT nothing going
07:19 PM Tom_L: too crouded?
07:20 PM _unreal_: lack of
07:20 PM roycroft: i can't ever go to see the fireworks displays
07:20 PM * veegee .
07:20 PM roycroft: because i have to stay home with a hose in hand for when the neighbors shoot bottle rockets into my yard
07:20 PM _unreal_: lack of crowd, no craft fairs, food things nothing
07:20 PM * veegee hurls a crocodile at Tom_L
07:20 PM _unreal_: all the bars are open though
07:21 PM _unreal_: roycroft, palm to face JUST SET the sprinklers going
07:21 PM * roycroft should go do the final machining
07:21 PM roycroft: i have half an acre
07:21 PM roycroft: it's a lot of yard to monitor
07:23 PM veegee: > The crocodile weighs 4x as much as the alligator and crushes it merely with its own body weight
07:23 PM veegee: > The attack is highly effective
07:27 PM veegee: > The crocodile proceeds to waddle over to roycroft 's property and kindly inform him that 0.5 acres is 2,000 m^2
07:30 PM veegee: > The crocodile then defends his property from stray illegal fireworks as a gesture of love and friendship
07:41 PM burklefoo: roycroft: we have about an acre but with the drought the sheep have eaten the weeds down to 1/2" nubs
07:54 PM burklefoo: so not much danger of a fire in the yard, but there's still a crazy amount of illegal fireworks here.
07:55 PM * CloudEvil wonders if sheep are flammable.
07:56 PM CloudEvil: With the lanolin and ...
08:06 PM burklefoo: They are hair sheep so don't have much wool or lanolin this time of year, so probably not too flammable...
08:13 PM roycroft: all fireworks are banned in 2/3 of my city due to the drought
08:13 PM roycroft: i'm sure there will be dozens of citations issued tonight
08:14 PM roycroft: and i would not be surprised if there are some fires set by fireworks tonight
08:15 PM roycroft: i have one drawer pull machined, sanded, and ready for finish
08:15 PM roycroft: it turned out great - i'm sure i'll improve as i make more, but it is almost exactly what i hoped it would be
08:16 PM roycroft: tomorrow i'll finish sanding the rest - that will take an hour an hour and a half
08:21 PM CloudEvil: :)
08:21 PM CloudEvil: how many you making?
08:26 PM roycroft: just a half dozen for this project
08:26 PM roycroft: but i intend to make a lot more down the road
10:20 PM drdoc: I have a noob LCNC question
10:21 PM drdoc: "touch off" in Axis' manual control panel sets *current position* to zero, yes?
10:22 PM drdoc: as opposed to moving the slected axis till it triggers a sensor
10:52 PM Tom_L: it will touch off the axis you have selected yes
10:52 PM Tom_L: to set the tool height you touch off the tool z only
10:53 PM drdoc: right
10:53 PM drdoc: OK, that's what I needed
10:53 PM drdoc: I think I have this thing ready to cut parts
10:58 PM Tom_L: dry run it
11:11 PM XXCoder: walk it in too
11:15 PM XXCoder: lol https://youtu.be/DbcEL514FV4
11:15 PM XXCoder: someone 3d printed fracial vise
11:30 PM FinboySlick: I really liked the HTR video. I had seen 'pin' vises for irregular shapes but never the fractal ones.
11:31 PM XXCoder: yeah
11:46 PM snakedLX is now known as snaked
11:58 PM veegee: XXCoder
