			I don't have any full size. You could glue a few together.
		
		
	 
That's what I was thinking too...  If you just wanted the foundation/drilling to be solid and the height for design, then just glue a standard BSA block to the top of a sugar pine block.  Some wood glue and a couple clamps would do the trick.
