I got to conduct a quick shopping raid on Crosscut Hardwoods this afternoon. Came out with a nice 4' x 8" x 8/4 piece of walnut from which will come many risers, a 7' X 8" x 3/4 clear black walnut plank, which can make limb lambs or be used in laminated risers, and 3 assorted 3/4 planks of nice maple... two clear grain and one with a little curl. This gives me more variety acceptable stuff to work with than just the red oak and hickory I have had on hand.
They had a lot of elm... but no red elm... just "elm" and "white elm". I know that red elm is a favored lam wood. I'd be interested in any comments or comparisons between red elm and other elms. If white elm is anywhere near as usable as red, I have a heck of a source right close by.
