Yeah, the idea is is just to use it for the top. You'd be a seriously lucky person to find a piece of buckeye big enough to make a body with that wasnt filled with cracks and holes! Also, buckeye's very hard to work with. The strength of the wood fluctuates throughout and is liable to break easily so it's bets just to use it for the top. If I can get enough and it doesnt cost too much, maybe the bottom too would look pretty good.
Anyway, thanks for all your suggestions, I've fired off emails to all of them and hopefully i'll be getting lucky and soon enough i'll be able to get started! Dont worry folks, there will be a build diary forthcoming!
