Ok I had a little fun over the weekend! I made a linear slide assembly. It was really easy to cut the members to length. It’s a two step process; cut then sand. First you measure and apply a piece of masking tape on the part you want to cut. The tape stays on the keeper part. You cut it with a band saw about 30 thousandths long. Then using a table belt sander you finish the process by sanding the last bit off. The result is a perfect cut part.

I made this demo 12" x 6". It’s almost 6" of throw. The belt I had was a little small for the full 6" of range. But using a 10 turn pot it is possible to go up to 25". I plan to make a 12" and a 24" table. Maybe not the 6" one as it’s not a lot of throw. Alas it’s all I could make with the on hand parts.

I attached the flanged ball bearings to the base rotate part. They will have some nylon washers added to ride inside the groove, but for now it’s actually the flange that’s riding in the small grooves.

The 10 turn pot is not designed for the loads on the shaft, but this is not intended for light industrial use. More like science fair entry. However there is no reason motors and encoders couldn’t be used instead.

Similar to that.
I need an external pot for HS-7955TG that would be the same value as the internal pot.
