You have cut away any covering in the glue area, RIGHT ?? Glueing wood to covering or covering to anything doesn't make a good glue joint. Think about it >> you glue to the covering and all that's holding is the adhesive on the covering. Good Luck !! ENJOY !!! RED
Very good advice Red. And to add to what he said, do not use a knife of any sort to cut away the covering from the stab surface. It's too easy to cut too deep and score the wood underneath, which can lead to the wood breaking while in flight. Instead use a soldering iron to melt through the covering to remove it.
Hope this helps
