I have to admit I'm a CATM, (Cheap A$$ Tool Maker). Why should I buy something I can build, anyway? I recently purchased (and am quite happy with) one of Matt's Precision Machine PM25 mills. Of course, it doesn't have table feed. I think I can build one.
I purchased for this project a 3/8" Variable Speed, Reversible Drill Motor. ($8.00 reasonable). (It has ball bearings on the armature). I have various DPDT center off switches and Potentiometers.
Below I have drawn, along side a plan of the electric components in the drill motor, the pot and the DPDT switch, and the Brushes and the Field Contacts, illustrated in the plan. There is no electrical connection between the switch/speed control and direction control inside the machine, it's all as shown with wires.
I'm hoping someone here can connect the lines so that I can duplicate the speed control and direction control with out my using the existing switch/speed control and direction controls.
Yes, I realize the DPDT diagram does not include center off, live with it.
Thanks in advance for bailing me out of this predicament.
