There have been an inordinate number of posts and inquiries regarding the suitability of JB Weld to perform repairs that are normally carried out by a skilled welder / frame builder.
There is a reason certain assemblies on bicycles are brazed and welded and this is because brazing and welding offer the needed bond strength to make sure that things stay together and resist stress and fatiigue.
JB Weld is an epoxy glue and is only for light duty applications... the bond strength on a brazed joint is at least 30 times stronger.
Damaged frames are generally not worth repairing due to the relative cost of the repair compared to the value of the frame.
If you do have a damaged frame or fork talk to a professional mechanic and even better, find a frame builder as some small issues can be repaired rather quickly and might only cost you a few cold ones.
I prefer IPA.
