Ron,

I've used the Foredom for a long time and can't imagine how I shaped hammers
for 25 years without it.  My use of it is for rough shaping, followed by
hand work.

The only real hint I can offer is to have lotsa belts.  The inherent
instability of the belt (each seems to be custom made), and the use to which
we put them, seems to mean unevent stretching and wear.

I find the problems to be miniscule, especially when one needs to remove 3
sheep from a set of ill-formed hammers.

Other comments?

Best,
