I'm going to build a simple workbench for my cabmate and trim saw. I've seen where people mount the motors under the bench, and if I remember correctly the motor is attached to a board with some hinges so gravity pulls the belt tight. Does anyone have any design ideas or workbench pictures of something like this? Here is a little drawing I made to give you an idea of what I am talking about trying to do.

I did that with my expando drum. You just put the motor on hinges and let the weight of the motor hold tension. I found that the motor was a bit heavy so I put a long bolt through the top of the table that extends through the motor mount and put a wingnut on it so I can tighten or loosen it as I see fit.

My old grinder stand was set up that way. It had a metal support bar across the front of the stand (you could do it behind as well) that had the hinge welded to it. The motor mounting plate was welded to the hinge.

The weight of the motor is usually fine for belt tension. The mount itself makes a fulcrum more or less. If you don't have shop tools, go down to the local welding outfit and ask them to cut the metal for you and take it to a local muffler shop to have it welded up (they might do it cheaper than the local welding shop who might want one shop hour to do it. I'd use simple angle iron and threaded rod to make the mount. quick and easy.
