04:10 AM Tom_L: rue_shop2, there are 2 schools of thought on depth of cut. oldschool is more shallow wider cuts and newschool is deep narrow cuts. the latter takes less HP and actually removes material quicker
04:21 AM Tom_L: by depth i mean full flute depth and a few thousandths wide
04:21 AM Tom_L: oldschool would take about 3/4 width and depth of the cutter diameter at the chipload recomended for that cutter
04:21 AM Tom_L: generally the chip load is somwehre between .001" and .004" per tooth depending on machine rigidity, HP etc
04:21 AM Tom_L: rpm can vary as long as you maintain the chipload. that way the cutter is working enough not to gauld etc
07:52 AM rue_mohr: hmm
07:52 AM rue_mohr: heh, that is the fan of a computer in storage
07:53 AM rue_mohr: I'm thinking of moving the stuff there somewhere else and putting in a stack of storage bins
07:54 AM rue_mohr: if so, I need somewhere to put sheet stock.

07:54 AM polprog: meet Laser, our rabbit
07:55 AM rue_mohr: mhm
10:42 AM aandrew: heh nice rabbit
10:43 AM aandrew: we have a family of wild rabbits that have been in our backyard for several years, you see the little ones in the spring and then they get big real fast
10:44 AM aandrew: we also have a hawk who (to my knowledge) has been unsuccessful in catching them, although last week there was a big ass turkey vulture in the back yard eating something that I thought was maybe a rabbit the hawk caught, but when I went to check it out it was just a pile of feathers
10:44 AM aandrew: so something got the bird and then the vultutre got the leftovers
08:27 PM rue_mohr: cast pullies
08:27 PM rue_mohr: fix truck
08:31 PM Tom_L: you fixed truck already. now what?
08:38 PM rue_mohr: no I have a list for the truck
09:29 PM rue_shop2: https://www.amazon.ca/58pc-Slot-CLAMP-Clamping-Bridgeport/dp/B00R5E5P0E/ref=sr_1_1
09:29 PM rue_shop2: ?
09:29 PM rue_shop2: shoudl I?
09:29 PM rue_shop2: or just make them
09:31 PM rue_shop2: this thing keeps tieing back to bridgeport
10:02 PM Tom_L: i just make what i need but they may be handy
10:02 PM Tom_L: i'd put the 88 toward a mesa card and lcnc :)
10:07 PM Tom_L: your table is small enough you wouldn't likely use half those
10:08 PM Tom_L: just make sure the slots are the right size
10:18 PM rue_mohr: I like the sound of it
10:22 PM Tom_L: sound of what?
10:41 PM rue_shop2: making my own
10:41 PM rue_shop2: I wonder how long a CO sensor cell lasts for
10:42 PM Tom_L: no idea
10:42 PM rue_shop2: I'm guessing not since 1992
10:42 PM Tom_L: do you know what size t slots it takes?
10:42 PM rue_shop2: 7/16
10:42 PM rue_shop2: w/ 3/8 thread
10:43 PM Tom_L: you could find some t-slots and studs maybe but i suppose if you're gonna do that you may as well get the kit
10:43 PM rue_shop2: I wonder if i can mill 3/8 square nuts to work
10:43 PM Tom_L: sounds like that machine is pretty solid
10:44 PM Tom_L: the shoulder probably wouldn't be wide enough
10:44 PM Tom_L: the 3/8 would slide back & forth in the slot and the nut wouldn't stay centered
10:45 PM Tom_L: and they're not gonna be as hard
10:45 PM rue_shop2: a buddy was saying to not worry about hardening them
10:46 PM Tom_L: maybe not on that small machine for hobby use
10:46 PM Tom_L: they can always be replaced
10:47 PM Tom_L: all my holddown stuff is 3/16
10:47 PM Tom_L: :)
10:47 PM Tom_L: but i don't have t-slots either
10:47 PM Tom_L: just a grid of tapped holes
10:48 PM Tom_L: got a new parallel cable coming for mine. the old one is getting pretty loose and that's the link to the pc
10:49 PM Tom_L: i had to use one of those gender changes on it and it's not screwed in solid
10:50 PM Tom_L: you'll probably find out steel will be a chore for it
10:50 PM rue_shop2: I'll tread carefully
10:50 PM Tom_L: 4 flute endmill
10:51 PM Tom_L: ~800-1k rpm maybe 5ish ipm
10:51 PM Tom_L: maybe a bit more
10:51 PM Tom_L: i'd have to look at my tool table
11:00 PM rue_shop2: ooo I could make them in 1/2" plate
11:00 PM rue_shop2: I have some misc pieces of 1/2" plate
