Figured I may as well chime in. I'm working a couple of really clean, straight grained Maple boards right now and I may pull out a slippery elm stave I've been seasoning. The one maple board is 72" long and 2.5" wide. So I'm going with a pyramid style bow, 5" handle, 1.5" fade out from the 1.5" wide handle and then it tapers down to .5" tips. The other is 66" over all, 5" handle, 1.5" flade out to the 2.5" and then tapers down from there to .5" tips. I'm gonna use the left over wood on the board to glue on a handle to beef it up a little bit. I'm hoping to get them cut out this weekend and start floor tillering. I hope to post up some pictures at that time.
