Wiring is simple as seen in this schematic.
|Control panel that houses the controller, switch, and pot. |
The switch plate is a bit garish but fun.
I designed a speed chart to go around the potentiometer. To see how I determined speeds, see my post on a shop made strobe tachometer.
Pictures of my DC motors and controllers.

|Back of potentiometer|
|1.5/2.5 HP DC motor|
And on the lathes. First pic has messy wiring, later I made it tidy.
Same motor on my Goodell Pratt lathe.
