More on the turbo platform..

Since one of the techniques is to twist the wire till it breaks...IMO this can be a little tedious.

It strikes me that it would be relatively easy to drill a hole in the knob and epoxy in a shaft...then use something like a cordless screwdriver to do the turning....my cordless screwdrivers have gone belly-up so currently I have none but if I remember correctly you can run at a fairly slow speed?????

What do you think?

The shaft should be out of the way for manual use.

Any better ideas for a power source? Dremel tools seem too fast.
