The best motors for small to medium size VDG's are, by far, those little
sewing machine motors, They have gobs of low end torque, are a brushed
motors, can be controlled with a single-pole light dimmer. and cheap. Most
sewing machine repair shops have used ones for $5 to $10.

Initially I decided to go with the traditional build. Id had my
fill of electronics and wanted something different (I then built a uP
speed control for the motor)
So, hair dryer v High voltage supply.
I've thought about it, but I'd need to change my bottom roller to
Aluminum. I don't have the workshop tools to make another crowned
roller. The last two rollers were machined for me, so it will have to
wait until someone with a lathe owes me a favour..
You can wrap tape around the roller to make a crown. All it needs to be
is a bit bigger in the middle than on the sides.
