05:56 PM jthornton: beer?
06:00 PM jthornton: JT has some 198 proof alcohol...
06:11 PM roguish[m]: Lcvette: hey you out there?
06:13 PM jthornton: no bike grease yet... I'm wondering if I can use something else to assemble the crank into the bottom bracket?
06:13 PM * roguish[m] posted a file: Carriage4.STEP (218KB) < https://matrix.org/_matrix/media/r0/download/matrix.org/VrjskFXMazqQxVbjuPixcbfR >
06:14 PM roguish[m]: Lcvette: could you look at this model, and tell me how you'd make it?
06:15 PM roguish[m]: jthornton: generally bottom bracket grease is just good, water proof stuff.
06:15 PM Lcvette: Yo
06:15 PM roguish[m]: Lcvette: just uploaded a STEP model.... could you check it out.
06:15 PM jthornton: hmm I might have some lower unit grease from the bass boat
06:16 PM roguish[m]: i've been asked to help a student finish his seniior project. since he's locked out of the university for the rest of the school year. he's trying to find someone that can make the thing.
06:17 PM roguish[m]: doesn't havve much money.
06:17 PM roguish[m]: jthornton: any bike shops closse bY?
06:17 PM jthornton: one, but...
06:18 PM Lcvette: Downloading
06:18 PM roguish[m]: this is really common https://www.amazon.com/Phil-Wood-3-Ounce-Grease-Tube/dp/B000WYANAG/ref=sr_1_1?dchild=1&keywords=phil+woods+grease&qid=1587597472&sr=8-1
06:19 PM jthornton: I'll give it a few more days... my exhaust is showing up tomorrow and chicks ship next Wednesday
06:19 PM roguish[m]: jthornton: you just have tooooo many toys.
06:20 PM jthornton: https://www.amazon.com/gp/product/B000NORVHI
06:20 PM roguish[m]: more power to you. just envious here.
06:20 PM jthornton: this is what I ordered
06:20 PM jthornton: worked long and hard to get here, now it's time to play
06:20 PM roguish[m]: jthornton: that's good too.
06:20 PM Lcvette: roguish: what's the length of the through holes
06:22 PM jthornton: that's an interesting part for sure
06:22 PM roguish[m]: it's all to scale. holes are through. 3.0 deep/long
06:23 PM roguish[m]: Lcvette: can probably do without the rounds and chamfers.
06:24 PM jthornton: you would need some fillets where the middle meets the ends if your using a ball nose end mill
06:24 PM roguish[m]: I told the young guy that's what I call 'prettyfying' . looks good, but cost lots. especilly for a 1 off prototype.
06:24 PM jthornton: aye
06:24 PM roguish[m]: jthornton: yeah, small changes are probablby ok. at this point
06:26 PM jthornton: that would be a bunch of ops on a VMC even if you had 5-6 axes lol
06:26 PM roguish[m]: i'm thinking stand it up on edge and go around to do the cylindrical parts, them lay it down and contout the rest
06:26 PM jthornton: seems plausible to me
06:27 PM jthornton: what material
06:27 PM roguish[m]: 6061-T6
06:27 PM jthornton: not bad then
06:29 PM roguish[m]: Lcvette: what da ya think?
06:29 PM jthornton: weather sucks until Sunday so no rush to finish the MB
06:29 PM roguish[m]: ew
06:30 PM roguish[m]: we're up in the 70's right now. staying for at least the next week.
06:31 PM jthornton: we still have a few mid 40's nights so covering up the tomatoes at night
06:32 PM jthornton: counted 36 Cherry tomatoes today
06:34 PM Lcvette: Holes vertical
06:34 PM jthornton: well they changed the forecast to 50's at night for a few days then a couple of 40's
06:35 PM Lcvette: Use a ball nose endmill to create the fillets
06:37 PM Lcvette: Of its only 3" that's a fairly easy part
06:38 PM roguish[m]: Lcvette: easy for you to say......
06:38 PM Lcvette: Nothing to crazy
06:38 PM Lcvette: One flip
06:38 PM roguish[m]: I have a reamer for it. and can peck drill the holes ok, i think
06:38 PM Lcvette: Probably need soft jaws cut to hold it properly
06:39 PM Lcvette: The holes are easy
06:39 PM Lcvette: The outside with the curvature will take some cam fun
06:40 PM Lcvette: Probably 3d rough and select a finish strategy that best suits your desired result
06:40 PM roguish[m]: ok. the complete thing with the holes vertical.
06:41 PM Lcvette: Ebooks will need to be able to cut slightly more than half the depth
06:41 PM roguish[m]: once around like half way down. held in flat vice jaws.
06:41 PM Lcvette: * Endmills will need to be able to cut slightly more than half the depth
06:42 PM Lcvette: I would do one flip
06:42 PM roguish[m]: flip and hold in soft jaws with hole bored to match the just done cylindrical parts.
06:42 PM Lcvette: Is or symmetrical?
06:43 PM roguish[m]: yes. 1 way. down the centerline perpendicular to the holes.
06:43 PM Lcvette: So one set of soft jaws can handle a flip
06:43 PM roguish[m]: yup
06:44 PM Lcvette: If your machine is accurate should not have much of a line from the flip
06:44 PM Lcvette: How many?
06:46 PM roguish[m]: well, he had hoped to make 10 for testing, but he really needs 1 for finish the assemlby. and his class, and get graduated.
06:46 PM roguish[m]: what would you charge? for 1 ??? for 10?
06:47 PM roguish[m]: just estimate... not absolute quote.
06:47 PM roguish[m]: 10, 50, 100, 1000, ...???
06:47 PM roguish[m]: $$$$$$ that is
06:49 PM Lcvette: For one hourly
06:49 PM Lcvette: $150/hr
06:50 PM Lcvette: Plus materials
06:53 PM roguish[m]: he has a quote for 1 for $600. I think it scared him.
06:54 PM roguish[m]: I told him 'welcome to the real world...'
07:02 PM TurBoss: <jthornton "beer?"> carajillo!
