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...

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 . I don't "do" any welding even Oxy Acet. so that annealing is out. As to how much machining is...

I have a small piece of the stuff but am going to need several square feet at least. It's about .005" thick but would like some even thicker if possible. The stuff I have is like very thick Food wrap foil . I want to use it to cushion the knurl when I hold a bunch of parts in the lathe chuck to fini...

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...

I sounds like he was trying to put the insert in without taping the hole first.

<If I use a carbide spot drill, will it stay on location, or will it "skate" on a slippery brass surface?>
It wont "skate" as far as the play in your spindle bearings .

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 .

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)
