Not having access to a lathe, I had to come up with an alternative method of shaping the banjo rim. There are a few different possibilities, but I decided on using a router table and sanding drums.

The English Sycamore rim was made using a block construction and then each later routed to approximate dimensions using a template bit.

The 3 layers where then glued up using dowels to align the rings.

Once the three rings were sanded flush using a sanding drum and a template to keep things even.
