06:28 PM unterhausen: well, my first print was a failure. Basement is full of filament now, looking for my machete
06:29 PM Tom_L: look like a ghostbusters scene?
07:17 PM CaptHindsight[m]: the original cordless drill https://www.youtube.com/watch?v=zTyZgOkWs4o
07:23 PM XXCoder: oh thought it was new videpo. was wondering why it didnt show up in my rss feed
07:24 PM CaptHindsight[m]: XXCoder: I wouldn't mind having a hand cranked version now
07:25 PM XXCoder: lol my brother got hand cranked, and screw type drills from dad
07:25 PM XXCoder: also couple hand powered buzz cut
07:29 PM XXCoder: https://youtu.be/JnT0vDpyUs8 fun
07:29 PM XXCoder: 3d print to bronze casting
07:39 PM roycroft: i still use a yankee screwdriver on a regular basis
07:40 PM roycroft: it is very portable, and i never have to worry about running out of battery
07:45 PM XXCoder: always heh
08:52 PM roycroft: more pricing weirdness
08:52 PM roycroft: i'm looking at some angle brackets
08:52 PM roycroft: i found some on amazon that might work out
08:52 PM roycroft: they are $4 each, 5 for $71.69
08:53 PM XXCoder: weird
08:53 PM roycroft: yes
08:53 PM roycroft: those are faztek
08:54 PM XXCoder: buy 7, put them together and resell on amazon lol
08:54 PM roycroft: i looked at 80/20, which are the extrusions i'll get
08:54 PM roycroft: theirs are $4.33 each
08:54 PM roycroft: but shipping is $9.15
08:55 PM roycroft: for each one - i added 5 to my cart to see what the total shipping would be, and it's $21.65 for the parts and $45.75 shipping
08:56 PM roycroft: if i get the 80/20 parts, i'll order them direct from 8020.net
08:56 PM XXCoder: unfortunately too expensive for me to
08:57 PM roycroft: but at those prices i'll almost certainly just buy a piece of aluminium angle and make my own brackets
08:58 PM XXCoder: expecially if you has a cnc to make nice brackets, but not required
08:58 PM XXCoder: cnc ... or mill
08:59 PM roycroft: i can buy a foot of 1.5" x 1.5" x 0.125" angle for $4.03
08:59 PM roycroft: and with that i can make 20 or so brackets
08:59 PM roycroft: no, it's just a piece of angle with two holes drilled
08:59 PM roycroft: i don't even need a milling machine
08:59 PM roycroft: a drill press and a band saw are all that i need
08:59 PM XXCoder: for plain type yeah
09:00 PM roycroft: but i did the right thing
09:00 PM roycroft: i checked for pre-made brackets before deciding to make them myself
09:00 PM roycroft: at $2 i'd probably just buy them
09:00 PM roycroft: but at $4 they are getting expensive
09:01 PM roycroft: and the shipping makes them unaffordable
09:02 PM XXCoder: yeah too much shipping wow
09:02 PM XXCoder: 9 usd geez
09:10 PM JoseIgnacioRome4: Speaking of sticker shock i just got my gas bill. Jesus
09:14 PM roycroft: i'm so glad i don't live back east and i'm so glad my heat is not gas
09:15 PM XXCoder: electric heat here also
09:15 PM XXCoder: using heat exchange system in my room, rest just stright power to heat
09:18 PM * Tom_L gives roycroft keys to the kingdom: http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/13.jpg
09:19 PM XXCoder: and a finger too. wow
09:20 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/10.jpg
09:22 PM JoseIgnacioRome4: Gas is like double now
09:31 PM unterhausen: I always thought Misumi was the place to buy extrusions
09:33 PM roycroft: i'm not familiar with misumi, but i'll definitely check it out
09:34 PM roycroft: as long as they have what i need, and it's straight and priced reasonably, i'd be fine with another brand
09:34 PM roycroft: 80/20 is the one i know best
09:34 PM Tom_L: what size are you looking for?
09:34 PM Tom_L: nevermind...
09:35 PM roycroft: 1545 and 3060
09:35 PM Tom_L: angle
09:35 PM roycroft: oh
09:35 PM Tom_L: i can read
09:35 PM roycroft: the angle will be 1.5"x1.5"0.125"
09:35 PM roycroft: aah
09:35 PM roycroft: i may even have some in the shorts shelf
09:36 PM Tom_L: i bet hd has that at a greatly inflated price
09:37 PM roycroft: and i don't know that i need that size
09:37 PM roycroft: but it's what is in the plans as of right now
09:38 PM roycroft: i'm not a professional machine builder, and i can't just design starting from one end to the other without backtracking and changing things as the design evolves
09:38 PM Tom_L: https://www.homedepot.com/p/Everbilt-1-1-2-in-x-96-in-Aluminum-Angle-Bar-with-1-8-in-Thick-802617/204273956
09:38 PM Tom_L: it's probably 'O' material too
09:40 PM roycroft: well as i said, i probably have enough on the shorts shelf
09:40 PM roycroft: and if not, coyote steel will have it for a fraction of home depot prices
09:41 PM Tom_L: then you must ask: do i want square or radius'd corner
09:41 PM roycroft: radiused
09:41 PM roycroft: i don't want architectural
09:41 PM Tom_L: then hd is out for sure
09:42 PM roycroft: although this will just be to support some channel that will support some drag chain
09:42 PM roycroft: so architectural would work
09:43 PM roycroft: but i don't like sharp corners
09:43 PM Tom_L: i used a flat piece and tacked it in place
09:45 PM roycroft: i could probably just use a piece of angle that is the full length of the axis
09:45 PM Tom_L: no need to
09:46 PM Tom_L: if you support the end, the rest will stay there
09:46 PM roycroft: but i want the channel so i don't have to use drag chain for the whole length
09:46 PM roycroft: well i have some on order
09:46 PM roycroft: so i'll be experimenting with it soon
09:46 PM roycroft: that's why i ordered it now
09:46 PM roycroft: but i still need some channel
09:46 PM roycroft: i figure on the x axis i'll start the drag chain in the middle of the axis and run it to the far end
09:47 PM roycroft: there's no need to use it on the near end
09:47 PM roycroft: i'll just hard tie the cables for the first half
09:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Wiring/X_Axis_Dragchain.jpg
09:48 PM Tom_L: i brought mine out the middle
09:48 PM Tom_L: and tied it underneath as you said
09:48 PM Tom_L: that piece is all self supporting
09:48 PM roycroft: hopefully the stuff i get will work out that way
09:49 PM roycroft: then all i'll need is a bracket in the middle
09:50 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Wiring/X_Axis_full_right.jpg
09:50 PM Tom_L: that's the extreme one direction
09:50 PM Tom_L: not enough droop to matter
09:51 PM roycroft: yeah, i'd be fine with that
10:06 PM roycroft: that's 15x30?
10:25 PM Tom_L: that was 10 x 15
10:26 PM roycroft: oh
10:27 PM roycroft: so the stuff i ordered will probably sag even less
10:27 PM Tom_L: probably so
10:28 PM roycroft: i added up the cables/tubing i need to run, and 10x15 will be too small
10:29 PM Tom_L: yeah for z it would be
10:32 PM roycroft: especially since it's water-cooled
10:35 PM perry_j1987: evening
10:35 PM perry_j1987: you'r building a big mill Tom_L ?
10:38 PM roycroft: i don't think tom_l is building another mill
10:38 PM roycroft: but i'm building a cnc router
10:38 PM roycroft: which is what we've been discussing
10:39 PM perry_j1987: the pictures he posted?
10:39 PM roycroft: those are the machine he already built
10:39 PM roycroft: unless i've been missing something here
10:40 PM roycroft: which is quite possible
10:42 PM perry_j1987: oh
10:43 PM perry_j1987: it looked bigger than what i remembered heh
10:45 PM Tom_L: i just took lots of pics in case it would help someone later on
10:47 PM perry_j1987: how has it been treating ya
10:48 PM Tom_L: just fine
10:49 PM perry_j1987: i got ballscrews enroute to arrive by wednesday it says
10:49 PM perry_j1987: finalizing the cad work on the brackets i need to mill up this weekend
10:54 PM perry_j1987: finally get some ballscrews on this mini lathe
10:56 PM roycroft: i'm still in the design phase
10:57 PM roycroft: i've bought my spindle and vfd and spindle mount, and just ordered some drag chain so i can work out how i'm going to install it
10:57 PM roycroft: but other than that i'm not buying anything until i get the design finished
10:57 PM roycroft: oh, i bought the ball screw and linear rails for the z axis as well
11:03 PM perry_j1987: roycroft you look at the printNC router?
11:03 PM perry_j1987: their Z Axis doesnt look half bad
11:04 PM roycroft: i may have
11:04 PM roycroft: i've looked at dozens, if not hundreds
11:05 PM perry_j1987: has tramming features baked in
11:06 PM roycroft: i haven't pushd any new drawings in a couple days, but this is where i was at then:
11:06 PM roycroft: https://roycroft.us/CNC-Router/Full-Assembly-Preliminary-3.jpeg
11:07 PM roycroft: https://roycroft.us/CNC-Router/Z-Axis-Motor.jpeg
11:07 PM roycroft: i have tilt tramming built into the spindle mount
11:07 PM roycroft: tip tramming i can do with shims
11:09 PM roycroft: but since i haven't started building it yet, if i find a better way to do it i'm open to making a change
11:14 PM perry_j1987: aye take a peek at their stuff
11:14 PM perry_j1987: its one of the opensource designs
11:15 PM roycroft: having to use the machine as a conventional router table as well as a cnc router does limit a lot of my design options
11:15 PM roycroft: but i know i can make it all work
11:27 PM roycroft: my router will be bigger than that one, and i don't want to use a bunch of 3d printed parts for it
11:27 PM roycroft: but there may be some useful ideas that will translate to my build
11:35 PM perry_j1987: ya its the.z axis that looked interesting on their build
11:40 PM roycroft: i want an independently adjustable dust shoe on mine
11:51 PM roycroft: i can't really use that design at all
11:51 PM roycroft: i have to keep my y axis rails below the work sorface
11:52 PM roycroft: surface
11:55 PM roycroft: the plan is that when i'm done doing cnc operations, i move the gantry all the way to the rear, remove the spoil board, and then i can use the machine as a conventional router table
