I made a bearing seat out a piece of oak and believe it or not it worked. Just trying to figure out how to keep the swivel bearing in. It sits between two rubber bushings. The original piece used screws. I tried but thought the holes weakened the piece. It was around the screws that the original broke. I filled my hole with toothpicks and glue. I was thinking about a coat of shellac on the piece then put the bearing in hoping the shellac would help. It is a tight fit now. Any suggestions? The speed control shaft was broken and of course it wasn't a straight break. Did not leave much to file down either. A piece of 1/4 acrylic extend the shaft. Yes it is a bit crooked, but it works. The bellow is also shot but an aquarium air pump will solve that issue. So I am putting along. Will update as I progress.
I made a connecting rod for my old Craftsman saw out of 1/4" aluminum. The original was some type of plastic. the top bearing failed and burnt up the plastic connecting rod. I looked up the dimensions and found the bearings on Ebay. I bored the bearing holes on a drill press and pressed the bearings in retaining them with red loctite. It has been working that way for several years now. The difference with mine was it was not twisted 90 degrees like yours. Mine was straight. If the oak doesn't hold up I would bet you could make yours out of aluminum also you would have to have the aluminum welded together to form the 90 degrees any good weld shop that can handle aluminum should be able to do that.

Wayne..
how about if you made that part from aluminum and then you could use Loctite gray to hold the braring???
the speed control is a potentiometer (variable resistor).....
available from an advanced Radio Shack stores.. maybe even a Radio Shack..
just match ohm readings..

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....
