This set is made from white pine, from Home Depot, because my spruce supplier is closed on weekends.
The rings are 4 1/2" OD, 5/8" thick, to fit a pvc pipe coupling I used as a compression chuck for turning the inside. The overall chain is about 34" long, with 18 rings. Finished with satin finish polyurethane varnish, before assembly. Half of the rings are broken in cross-grain bending, stitched into the others, and glued with Titebond 2.
I also made a test with the same size rings, but in segmented cedar (2 layers of 12 segments each). The segments reached almost to the center of the ring for attachment to a faceplate, for turning the outside of the ring. Instead of breaking for assembly, I masked two locations of the pre-rings (i.e. without glue). I placed a drop of CA at those locations for temporary brittle assembly for turning, and glued them after final assembly. The finish here is EEE and paste wax, in three turning stages: outside, inside one face, and inside the other face.
Cheers,
Joe
