hey, machine tool dreamwidth!

I got a question!

This adjustable-hole-cutter I got has a max of 500 RPM and my newly assembled drill press doesn't go that slow.

BUT

The hole-cutter cuts holes up to 200mm. 500rpm is safe at 200mm, meaning the tool has a max safe rotational velocity of 314,000 mm/min.

So if I cut my 108mm hole at my drill press's slowest setting, that's a max OD rotational velocity of 250,860 mm/min.

That's much slower and well below the max safe outer-diameter rotation velocity of 315,000mm/min.

(at 200mm/500RPM, as above)

This sounds safe. But I could be missing something. Am I gonna put my eye out?

The war is won. Oasis and the Concordat are at peace. Overwatch has been folded up again, this time made into an intelligence arm for Helix, under new - and the UN hopes better - leadership. The Gods are free - largely - to do as they will.

Lena's found something she didn't expect to find, and she's very excited about it.
