The frame is two strips of 1/8” maple. I pre-bent them on a 30” form. The first ring was glued and tacked around the base. Rather than an exact fit, I drew from my knowledge of corking a clarinet tenon and tapered the starting end and overlapped the trailing end, then sanded it to the correct thickness with a disc sander. The second ring was done the same way with no tacks. I used a lot of spring clamps and small, slotted scrap pieces to get a good lamination.
