Re: 123 blocks Dumb Question

And while you're at it make some with 5/16 and 1/4 threaded holes to fit the slots. They come in handy often.

Re: Making carbide tipped boring bars

If you haven't caught Robin Renzetti on youtube, you should. He does some incredibly precise work. Here he makes his own carbide-tipped boring / internal grooving tools. He makes them so precise that he can swap them out on the CNC and keep going. https://www.youtube.com/watch?v=OjQ5pOkCeW0 Steve I...

Re: Dead soft Aluminum

I think that McMaster 1100 stuff would be the ideal but all I need for ever would be a 3 or 4 ft., a 50 ft roll would be overkill :-) All the cans and like has been tried in the past and is way toooo hard .

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...

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.

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)
