Greg,
I've done three with hhg, scraping the bottom of the bridge (not toothing
) to remove any oxidisation just prior to gluing. So far so good - the oldest one was put on in April last year.

Like Dave says, lightly sand the bottom to get a fresh surface. Yellow glue (Titebond). |

Hey Todd, Yeah, I've got some test pieces glued up as we speak ( exact coco I'm using to spruce), I'll let you know what I find out this evening. The funny thing is I tried some West epoxy and was not overly thrilled with the bond, so now I'm adding some Titebond, and fish glue to the mix. Greg |

needs to come off epoxy is not a good idea Phooey. Epoxy releases easier than Titebond or HHG. |

I agree with Mario on this one, epoxy does release very easily with seemingly moderate heat, and I found there to be little damage to the wood afterword!! I just performed some very unscientific tests on Titebond and fish glue adhesion between spruce and the cocobolo I'm using presently, they both left behind spruce adhered to cocobolo in some, but not all areas when struck with a hammer and chisel between the joint. I also used the chisel to remove the spruce that was left on the cocobolo, the fish glued piece was more difficult to remove.....I can't imagine either glue failing though as it took quite a blow to remove either piece.
