Furnas Reversing Drum Switch

I got thinking that I would use the switch as is.(forward only) My thoughts are that you really wouldn't want the motor go in reverse as it would or I should say could turn the chuck off of the spindle.I have reverse on the lathe.
Still need to mount the motor and drum pulley.
 
The option to reverse your spindle is the cutting of metric threads. An Inch lathe when used to cut Metric threads has to be reversed to reset the carriage back to the start position as you can not disengage the half nuts until the threads are done.

Or stop your lathe, reverse the feed direction, and restart the spindle to feed back to the start point.
