The cable stop for the front derailleur finally let go, I really don't want to mess up the paint, so I thought of one of these

and a quality metal on metal type epoxy, I'm not talking JB weld here, there are many types of specialized epoxy available to permanently bond metal to metal. I like the investment casting stop, mainly because it has a large curved surface that would seem ideal for bonding. Has anyone else ever tried using a quality epoxy to bond one of these? I forgot to mention, it's a Cromoly frame

I checked into the 3M scotch Lock epoxy, which is 27 dollars for the dual tube dispenser, I already have the expensive special dispensing gun, it's for industrial bonding of metals, that sounds about right. I guess thats cheaper then tearing up the paint

Sounds like you're on it. FWIW this might get more visibility in the mechanics forum.

I have this junk murray frame here, with stops that look almost identical to the supersport, I had an idea of cutting out a section of it's frame tube, and trimming most of it away from the stop, but leaving just enough to use a couple of stainless steel 3/32 rivets, if I were to paint it matching cool lemon yellow, it would be a nearly invisible repair, if I wanted to braze on a stop later, a little bit of tig weld would fill the rivet holes in the frame

Ok the piece is cut out of the murray frame, once it was blasted and trimmed up, it basically left a stop with a small curved shoe, this gives more area to bond to the frame. It's taped up and curing now, all of my exotic two part epoxies have hardened in the tubes, so it's down to a good two part standard epoxy, if it doesnt hold, I'll have to order some scotch lock

not very elegant, but these cable stops from Origin 8 work well for me

Ok even using these high tech epoxies didn't I work, I finally drilled 2 #40 holes in the piece and attached it with 2 high strength stainless rivets, I coated it with epoxy first then riveted it on, so far it's rock solid, it's barely noticeable, once it's primed and painted, you'll. Have to look close
