Re: New in town

I was thinking the same thing. If the "magic" word is "Stainless" just use some other BS terms like the alloy words and numbers to confuse the silly consumers. :-) Then there is always the magic word "Billet". :-)

Re: Brand New Smithy 1340 Max

Ah ! Just what I've been looking for. :-) Our local organization has one of these (I think it's the same model at least it says Granite on it) and we already have other lathes and a Bridgeport etc. so want to sell it and invest the space and capitol in some other more needed machines. So I have been...

It wont "skate" as far as the play in your spindle bearings . :-)

Re: Fire Danger

I can imagine that one of the big problems with any "Makerspace" is that everyone thinks they are an "expert" in any field that comes up.
:-( As my one and only (very recent) experience at one of them shows . :-(

Re: Starrett #123 26" Vernier Caliper

Old Pierre Vernier 1580 - 1637 would be roiling over in his grave if heard all the people using his name in conjunction with those devices with "Dials" or "digital readouts" on them. I don't know if it's ignorance or simply laziness. (Probably not stupidity)

Re: getting endmills sharpened...

Not true. It all depends on where you are. Here in Abq. we have a good sharpening service that we have used for years for end mills as small as 3/8" and up to 3/4" at prices that make it economical.

Re: Need to drill 1/2 sphere hole in aluminium and/or graphite - 1/2" - 2" diameter

You'll need a lathe for sure and a "radius turner" . I've done this many times. It's even possible to make the hemisphere a bit deeper than the radius. The tool bit needs to be a bit different than the common one but it's no great problem . I'll be happy to send you some pix if wanted.

Re: Matching a taper

Yes I can BUT the compound on the lathes I have access to are very suitable to do this on. First off they have nearly 5 inches of travel and a straight side that a dial indicator can follow. So I made a fixture that sits on the ways and measures how far the side of the compound moves while moving th...
