Treadmill motor powered Drill press (UPDATED April 26th 2016)
The Link belt setup is remarkable. I’ll admit Im pretty skeptical kind of guy. And, these belts fell under my watch full eye Im glad to report that they have not missed a beat. their quite , easy to adjust, re-useable, have great traction. inexpensive too. simply put? a win-win.

All, Several people have asked me for the circuit design. I did this mod so long ago I cannot recall where I left my Drawings. (but I do have them Im sort of a horder in that way) After a few mins of searching the Vast Interwebs. I found this. Link/Forum Thread (see #7) which seem pretty congruent with my install. with a few exceptions. The supporting schematic is below. As of Now (April 23rd.) I will confirm the schematic to my actual install and notate this post. But as of now. I have NOT confirmed.
The exception in my case
1: I did not use a choke.
2: If I recall I bypassed the Thermal switch on the motor.
After several years of use. this setup has not failed even once. the limit of my drilling is prob around 3/4 to 1″ (slinging a drill bit) that big and slow the torque just drops off so much its really not useable. Im thinking of adding a flywheel to the setup. but after all these years Im not likely to ever reach that project again. but its my opinion.
