I want to control "hand" in the hand drill press with a motor.
Why? Actually it is protype of custom cnc for drilling small metal parts (about 12mmx12mm). I already setup proxxon KT 70 with two step motors with arduino cnc board and it is working without problem. Actually I tried to use a rope directly with a nema23 step motor( sanyo denki 103g770-2517 1.1A 4.1V , probably 0.62Nm) , but it could not pull the hand. I checked instructables.com and there are many custom hand drill press or some tips related to this "universal hand drill press" drill stand, but I could not find something similar which is trying to control this hand powered drill stand.
I think I need a motor gear, but I dont know where is best place to mount this mechanism.
