Hi Jeff, You might look in a Sporting Goods store outlet and take a gander at Brownell's AcraGlass. It's used to bed rifle stocks. It sticks and welds to anything and the bond is stronger than the parent material.
I use it all the time bedding CF, FG and wooden stocks. It's sandable/ paintable and you can D&T it. It also doesn't shrink. A friend of mine made a gear for his lathe with the stuff. It's one of my favorite and useful things. Other than ViseGrips that is

.
