John, I know it will be a suck it and see to begin with. So don't worry, I won't run away with it. I am super methodical when I try something new. I will have to see if someone has a slow count rev counter, or I could lash up a finger counter and a cam. As I said, I have yet to make my screwcutting tooling. So when I get that done, I can resurrect this post. Thanks again John |

John, I tried a lot of ideas for counting the revolutions and finally settled on a rotary switch, but I did have to butcher it so it could go around and around! I used a laptop to do the actual counting but if you have an old calculator you can make it into a counter! Just open the calculator and connect up two wires across the '=' key, then close the calculator with the wires connected to your switch. Just press "1 + 1= =" and everytime you close the switch it will increment the count. Cheers. |
