This is about as far as you can get from fine woodworking, but… it works.

About a year ago I acquired a broken treadmill with a DC motor that I wanted to use for a variable speed conversion for my Jet 15 mill. That project was a success, and I saved a few of the other parts from the treadmill that looked like they might be useful. One of those was the drive roller, which looked like it would make a great outfeed roller for my radial arm saw. I had a portable folding roller stand, but it was a PITA… always in the way, always getting knocked out of alignment or completely over.

Fast forward a year. I was cleaning my shop last week and moving stuff around to make room, knocked the roller stand over once again, and decided it was time to do something about it. This is the result.

The roller is considerably longer than the old one, and rather longer than it needs to be. I wanted something that would stay accurately in place, while being able to be moved out of the way. The solution was to mount it on hinges to the wall, with a hinged leg to support the outer end.

The main frame is 2×4s, hinged to another 2×4 which is attached to the wall with three 5/16 lag bolts into the studs. Oversized holes in the back 2×4 give a bit of adjustability. The leg is adjustable as well, with a rubber faced machinery leveling pad on the bottom. The roller is mounted to a separate frame, held to the main frame with carriage bolts and wing nuts riding in slots to let it move if I move the rip fence. The end blocks of the roller frame are maple, the base is pine. Everything is held together with Titebond II and screws.

I left the plastic drive pulley in place, lined up with the fence on the RAS. At the outer end the roller shaft is threaded so a bolt through it gives adjustment of the angle to make it track straight (it was that way on the treadmill).

The white pegboard in a couple of the pictures is just there to provide a background for the photos. You can see the old roller stand folded up leaning against the wall behind the shop vac.

When not in use, I simply hinge it up and secure it with a bit of cord. Eventually I may clean that up to make it more elegant, and I may work out a way to adjust it closer or farther from the blade if I find it necessary, right now the hinges are just wood screwed to the 2×4 bolted to the wall.
