I'm going to tap the hole I drill in the frame, not a lot of threads, but should be enough. I tested this set up with scrap tubing (without the JB weld) to see how well the screw tightens down and it did just fine, its a small screw, and the old Raleigh 3 speeds have thick wall tubes, notably thicker than my test piece, so it will work even better in situ than my test.



Painting tiny pieces with an HVLP gun! And not have them blow across the garage...

I put screws through foam board, cut the tips off the screws off and super glued the pieces to the top of the screws, I'll grind the super glue off the back once they are painted for proper jb weld adhesion.
