Question Radial Arm Saw Problem

A while back I picked up an old 10-inch, Rockwell radial arm saw. It wasn't in great shape, but the price seemed right, and I always figure that if I canít fix it, it ainít broke. Well, I discovered a problem Iím not sure how to deal with. It seems that somehow, the rails in the radial arm that the roller bearings ride in have become pitted. This causes the saw to pull ďroughlyĒ. Iím not sure itís a big problem, but I donít like it. I think the correct ďfixĒ for this would be to weld a bead into the rail and have it machined out. However, I donít think the saw is worth that much work and expense. I was thinking about trying to fill the pits with JB Weld and sand it smooth.
Has anyone else had similar problems or other ideas for a fix?

If you don't want to put much time and expense into it, I'd say you're on the right track. JB weld, Bondo, or epoxy...any of those might well do the trick. Just sand or file them to match the rail and maybe put a coat of paste wax over it to help smooth out the slide.

Thanks MM and Rick.

I hadn't thought of using a little paste was in addition to the filler. That might help.

I think the rails are machined into the arm. However, I'll double check this weekend. If they were removable, that would simplify the whole thing. Even if I couldn't find replacement parts, I bet it wouldn't be too difficult for a machine shop to recreate. I suspect they'd just be a steel bar with a bead machined out.
