Re: [GrizHFMinimill] Re: griz 3in1
How much of a bite (in aluminum I assume) did you take when it took out the gears? I routinly take 0.035 with a 1.25 diameter fly cutter; in low gear.

It always seems to blow the chips into places I don't want them to
go. And that makes clean-up harder. I don't enjoy cleaning up, so
anything that reduces the effort is a Good Thing in my shop!
Using a reducer to allow a smaller nozzle on the vacuum helps
get into tight places - turn one out of plastic or aluminum on the
mini-lathe. Just keep the air flow high enough to keep the vacuum's
motor from melting down.
