I've been getting annoyed with my Harbor Freight Bead Roller....it doesn't have any way to prevent the driven roller from moving to the left during use. That causes the bead that I'm making to start out very crisp and sharped, but to gradually turn into a slope. (Very annoying.) Luckily, a fix is cheap, and easily reversible; I just put a hose clamp on the shaft for the driven roller next to the support for the shaft. Presto, no more movement to the left.
The actual amount of movement that occurs is a lot less than in the picture (I exaggerated it to make the change more obvious.) The red line with the dogleg represents the bead I'm rolling, and how it looks at the start and the finish of the workpiece. The hose clamp should be self explanatory.
I know this solution is not rocket science, but I thought I'd share it, just in case anybody else is having this problem, too.
A split shaft collar from your local fastener store would be a permanent and cheap solution.
