The cable driven hand piece is probably one of the most useful tool
you will have on your work bench. You will be able to grind, cut,
polish set stones, texture and many other operations with a cable
driven hand piece.
I am not sure what you mean by bench type. Rio Grande used to sell a
Foredom mounted in a heavy base that could be mounted anywhere. I
did not see that product in the latest catalog.
How and where you hang the motor will depend on you work bench and
I have several Foredoms. One is the old bench type, one is the
hanging type and one I just set on the table next to my work bench.
The main concern is how and where your are going to use the hand
piece. The flex shaft cable should not be bent in too tight of a
radius. The Foredom should be mounted so you can use the hand piece
without stress. The hanging cable should not be in the way as you use
the hand piece.
The size of the motor will depend on what you want to do toda and in
the future with your Foredom. Plan ahead and buy the size of motor
you might need in the future.
