I'm looking for some c-clamps for a crack repair... I need about an 8-9" throat, so 2-3" longer than Shop Fox bridge clamps. The soundhole is really small so my long cam clamps won't fit. I ordered some of these: http://www.harborfreight.com/8-inch-dee ... 45917.html which look cheap and ideal sized but they appear to be sold out. Any ideas?

How about these?

If you knock the corners off the lower arm of a StewMac 8 1/2" cam clamp, it will fit in most classical guitars. Don't know if that helps you.

Hmm... for this guitar not quite but if I made a cam clamp with a curved bottom like so:

it seems like the arch would make it stiff and the curvature would make it easy to fit inside a smaller guitar. Does anyone make something like this?

I have those harbor freight deep reach clamps. They are heavy as hell and would probably cause more damage then they are worth. I tried using them for an acoustic and you could actually see the top flexing from the weight of them. Tom West had the same exact idea for a clamp that I had when I first read your post.

Good to know about the HF clamps... I think I'll just make a curved-bottom cam clamp and see if that does the trick. The LMI clamp seems like a clever idea but looks very light duty... I need some pretty decent clamping pressure.

Ah, perfect... how did I miss those before?
