    Default crack repair

    I don't know where else to post this one, so here it is.

    I have some timber that I'm wanting to use for 1/2" - 1" drop tops on guitars, but it has a few cracks in it. They're large enough to be seen easily, but not so large they're structurally dangerous. Add that they'll be glued to another crack-free piece, and I don't think they'll be a stability issue. That being said, I want to repair/patch them as much as possible before doing any cutting/shaping on the slabs.

    So... what would be the best suggested course of action: putty, epoxy/sawdust, patching with "splinters", glue & heavy clamping, or something else entirely. I don't have any pics with me right now, but I can probably post one tomorrow morning. I'd estimate the cracks to be about 3-6cm long, and maybe 1-2mm wide at the most.

    Do you want to completely hide these cracks? If so, depending on what type of wood is involved, that is going to be quite difficult. I would experiment with something like an epoxy sawdust mix - but not on the actual piece itself. The cracks will still be visible, probably darker, but may blend in OK.

    The epoxy mix is correct, but if you want it to be structually sound its best to seal one side and end with a strong adheasive tape or anything suitable and pour the epoxy in, this way it will bond better. You can put some color into the epoxy with an oxide or just leave it clear.
