Well I will start off by telling you what I am building.

I am building a two axis linear positioning device. It goes onto a saw grinder. It is hand joged around to position to saw in the right spot to be ground. Then the saw is then pushed into wheel to grind the od. So all this is needed for is adjustments. Then it needs to be locked into place and not moved till the next adjustment.

The problem with the setup is how easy it moves. Someone just bumps it and it moves without even touching the jog handles. I need some way to put like a spring tension on the ball screw so it wont move on its own.

Also I am looking for some jog handles with measurements on it. My ballscrew is 5mm lead and I need a handle that matches that.

Thanks Smackre,
