Looking to fix an older, vintage alloy weinmann rim that is flat spotted.
Years ago I remember a tool that clamped on the rim and worked like a gear puller to pull the flat section out. Are these still in use ? Any other tricks in use ?
You're thinking of the Overland tool.
Rumor has it that one might crack a hollow or thin walled rim with it but I've never lost one. It's tedious as it's used after disconnecting several spokes. It's got a lot of leverage so the inattentive operator might easily go too far. But for the occasional irreplaceable damaged rim what else can you do?

That was the name of that tool! Didn't VAR make one like it, too? I've wanted one of those for years as it seems a bit more precise than the method Jobst described- loosening the spokes and hanging the rim over a 2x4 nailed to the joists in the garage and pulling. Effective, no doubt, but a bit more difficult to control.

That method works but since doing that, a friend gave me a "Rim True" tool by Overland Inc. (Grand Rapids MI) that has a rubberized flat hook with a spoke nipple slot and a curved brace that fits a 700c rim. The hook is suspended from a large screw with a dumbbell nut to pull up through a broad gap in the middle of the rim brace. It's a nice device but the 2x4 works as well.

There is/was another guy called RimTrue. That if I recall was an adjustable set of rollers on a plate which pressed at various points. I never saw one in the flesh.
I don't recall seeing anything like either one in the VAR book but I'm not the last word on that.
Again, in a pretty high volume wheel shop I use that thing once every couple of years. Absolutely a specialized tool for a limited set of circumstances. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971

I once made a set of blocks, carved from oak, to fix flat spotted rims. It was a labor of love but they worked. One block filled the rim and matched the contour of the rim OD plus tire bed. The other was cut to match the inner profile. I used a combination of bits in my router and made a radius jig to match the diameter of the wheel. It took about an hour to make the jig and about 5 minutes of pounding to get the rim back in shape.
before banging, cursing, and bending-rememeber re-trueing takes up lotsa wrong bend at low nipple torque levels. tightning the side's and loosen the flat spot, repeat repeat get 1/3 more pressure. the number of needed spokes narrows. then go to the opposite rim side and loosen. brong! less flat.
"And of course, the rim is no good for anything other than getting you home"? encouraging words. do yawl use conti pads? and that's what said when i began jumping on it sandwiched tween two slabs of particle/formica board: but its now rrrrround! whaddya mean "roll it back and forth"?

Having no idea how extensive the damage to the rim would be as a result of either the initial blow or the repair, let alone the persnicketyness of the owner, I felt it best to err to the safe side.
