I had a problem: I needed a lathe for a couple of chisel handles but
had no intention of buying one. My workshop is about 2,3 x 2,4 m big
and already pretty full and I did not want to waste money for something
that could be easily built anyway.
I have used my hand drill for all sorts of small turning tasks,
modifying screw heads, polishing anything that could be gripped in the
chuck and rotated etc. So the thought of using a hand drill as the
motor for the drill was quite obvious.
