rhm , good idea, consistant with those of us not rec. soldering to sove a tiny problem and create a bigger one, possibly that of paint work. Those frame used muti-coated finishes, electrostatically applied no less.

JB Weld or other met. based epoxy types create "metal", if they work to recontruct an ear on an exh. manifold, they'll work on the cabl.holding tip on a frame.
I'd thought about it, you said it. So you do in fact know.
