Split sides
Split sides
I am starting to 'assembly' my guitar, cutting bent sides to length etc. And one of the sides have split in the middle for about half the length of the sides.
I have quickly put a whole lot of glue on the split and clamped it, hoping for the best. Any ideas ?

I agree with Paul and this is what I would do too - turf that sucker....Paul B wrote:Yeah, turf it and get another pair of sides. You'll only be storing up trouble for down the track.
Of course, not everyone will agree with me, but that's what I'd do.

When you don't know what to do when something like this happens ask yourself this question: Do I want this issue to come back and haunt me later AFTER the guitar is completely built and finished?
You will know what to do...

Also - even though this sucks and I am sorry that it happened to you there is an opportunity here to learn why it happened. So with that said what kind of wood was it, how thick were the sides, quartered/not quartered, moisture content/seasoned, shape you were trying to bend, bending machine/pipe, bulbs/blanket/both, slats - what kind, bending stack - what did it look like, moisture used - if any to bend, temps used and time? Anyway if we knew a bit more about these things we could perhaps offer something that might help us all learn something for future bends.

1.) solid linings
2.) interior patches for sound ports, and/or access doors
If you had just cracked the side, and it was not yet glued, I'd say fix it, invisibly, and realize that with crossgrain reinforcement strips glued to the interior of the guitar that it will hold up forever. A good glue joint is stronger than wood. You may still be able to do this.
Did you get the alignment of the pieces really well aligned before clamping? If not, then this may be good just for solid lining strips. If "yes", then keep reading...
"I have quickly put a whole lot of glue on the split and clamped it" - what kind of glue, or more importantly, what kind of wood and what kind of glue? If the wood has large pores, and you really used "a whole lot of glue", you may have allowed glue to get into the pores of the wood near the crack. Not a problem for stability of the repair, but it may have left a telltale sign that the sides are glued, because your efforts to fill the pores won't be the same on raw wood pores as they will on glue-filled pores. It will show up as a repair when you apply finish.
If you used hot hide glue, or a white or yellow glue, then if the wood pores are tiny or if you were just kidding about lots of glue and actually kept the glue only in the crack, you should be in good shape. Nice save! Way to go! If the glue is in big open pores, well, I'd say slice it up for solid lining strips or keep it for pre-bent sound port hole liner material.
If you glued the crack with epoxy: then, it doesn't matter if it is in big open pores, as long as you are willing to fill all the pores on the guitar with the same epoxy. The repair and surface coatings of epoxy will yield an invisible repair, and epoxy "pops" the grain.
That's my $.02
