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.
great mod I also liked the caliper on the front nice touch i usea dia indicator old kind.
Hello, thanks for posting. Could you tell us how to do the mod to restart the drill press at the same speed each time it is turned off? I just picked up a treadmill to the same thing.
Alan, I have the schematic somewhere I did this Mod loong ago. Ill find it an email or post. either way I’ll you know. I use the speed mod every time I use the press. Sometimes it a pain. but most of the time its well worth it. -Sam
Hi Sam, I have been searching around and found a post where someone put a switch on the high leg of the POT. Then another where they cut the RPS3 resistor on an MC-60 control board. If you do not find it then I’ll try one of these methods. I realize it’s been 3 years so thanks for responding.
Alan, If I dont find the schematic today. I’ll just look at my drill press and let you know the wiring. (I’ll re draw the schematic.)
