I just finished this stitching clam. Its made of steam bent white oak and is 36" tall. The jaws are under tension and measure 2 3/4" at the top. The throat is 3 3/4" at the widest and 19" deep. The dark areas on the wood are a result of the steaming process. I based it off of plans available here- https://www.etsy.com/listing/249232297/leatherworkers-saddlers-clam-and. I saw his video on Youtube last fall and thought it looked really slick. I have a stitching horse that I made from the plan
