Hi ModCo, thanks for your response and willingness to do this, My address is :

Needless to say [but i will anyway lol] i dont need a humongous piece from the tree like you display, maybe 12-16 inches in diameter or square or what ever. The mian purpose is to work out on one side what strength gives the max results and then do the other side to show the final results. Shouldn't take me more than a few weeks. Also is it possible for you to prepare the surfaces exactly as you did yours so were in sync on this? thanks in advance, chemmy / sam
