    Alistair, I've a dumor 'speeder' or at least that's what i've always called it - is that what you mean? it spins at something like 20k with the smallest jacobs chuck. basically a high speed balanced motor with a chuck on the end. its used in the drill press chuck, simply as a way to hold it, the drill press is never turned on. actually I turn the breaker off because by rote i'd hit the green button, don't ask how i discovered that little personal weakness.



    sensitivity is increased if you make one of these, plans irrc in one of our sponsor's books.



    for very find work, its a sensitive drill press table, counterbalanced the table raises up into the drill. I've done #85 holes with this, it works.

          Nice!

          I have had a high speed, precision drill press for a long time. It is called a Unimat. Selection of speeds up to 10K RPM and with a fan speed control, I have continously variable speeds.
