won't know til i get a testable model done...have to get a friend or someone to turn some parts, but sure, i'll share the notion - here's a stupid bmp done in paint to suggest the design
er...lemme jpg that first...
well, lemme make a note or 2 on it first...
but i think it sort of makes the problems i've learned of go away.
this would be only 1/4 shaft - that's gonna maximize rpm - i don't care if there's a bigger chuck on the end - plz keep in mind, though, that this is for high speed laptop mills - not your 10 ton hog !
