speed control

[dave.williams@chaos.lrk.ar.us (Dave Williams)]

 I've been thinking about building a honing rig for honing blocks.  My
Sunnen cylinder hone works just fine, but it kills a 3/4hp drill in
short order.

 I drew up a nice rig using a 1hp industrial motor on an arm.  Looked
nice until I thought about varying the speed.  How can a vary the speed
of a 1hp (760w) motor?  Would an ordinary light dimmer work?  One of my
industrial catalogs had a dandy electronic speed control for only
$300... ouch!
