high speed drill.

[big o]

This drill was made to complement my Unimat DB200 lathe.It has a 4"stroke and the capacity can be increased or decreased by moving the motor up or down using a threaded rod on the back post.The motor is rated to over 20,000 rpm's on 36Volts.I run it on an 18Volt wall mount transformer ,it has good torque.RPM's are controlled thru a potentiometer .Chuck quill return is thru a spring taken from a 8mm camera.Base is a quartz cut-out off a counter top.Unit is bolted with "T"nuts drilled thru base.Wiring is hidden in holes drilled thru quartz base.
