How about JB Weld, stuff is cheap and is really strong!   I've used it to fix broken drill bits, and fix my weight lifting equipment!   I believe it bonds to mostly anything?

Also found this....
What does it bond to?
Virtually any combination of iron, steel, copper, aluminum, brass, bronze, pewter, porcelain, ceramic, marble, glass, PVC & ABS, concrete, fiberglass, 
wood, fabric, paper -- just about any porous and non-porous material.
