i have a steel road frame with really flat threads in the bottom bracket shell. there are cut lines which indicate it there had previously been a seized bb, and i guess it took some shell material with it. it's english threaded and a cinelli shell. a chaser goes in fine, but a cup rattles around.

i just tried filling the shell with jb weld and re-tapping to english - no go, all the jb weld chipped out.

now i'm looking for other options. i want to save reaming and tapping to italian as a last resort.

i'm thinking of trying loctite form-a-thread,

but i don't want to waste my time with more glues if it won't work. any advice?
