I've often wondered if I could use a strobe light to see my work without turning the lathe off, but I never thought of this:
Hey, we could also butter our corn on the cob! Safety shield in place, of course, for flying butter.
I use a variable speed lathe to ball mill pyrotechnic compounds. I also use the same machine to roll various sized and color changing stars used in display fireworks shells.
I'd like to see a video of the results of this, as I am nuts about pyrotechnics.
