I use the same as Steel.
It\'s either too old, too much, the surfaces aren\'t clean or the metal is too cold.
I find pinning helps if the pieces are big enough. but seriously:
1. Clean the surfaces,
2. check the fit (they may not meet flush?)
3. make sure the pieces are room temp (comfortably 60-80 degrees F.)
4. just a dab will do, just a touch to the smaller piece, and press firmly together, count to 10 or 15, then it should be fine.
If it still doesn\'t stay together, get a new bottle of glue.
CHEERS!
