Check out Sullivan. They've got then for sale and may provide specs.

Don Bryant (bryantde on the hangout) can help you. PM him. He’s a great guy, helpful, and an excellent luthier.

Go to figure 8. There is a good profile diagram. If you can print and blow it up to 3/4" rim width, you should have it all.

Hunter,

I have converted many tenor original pyramid Gibsons to 5 string over the years!  I have 2 original pyramid banjos in shop now but they are intact so I can't give you the measurements, but I sold Arnold Clayton an original pyramid a few years back and he had it duplicated with his own alloy and sold several and I put them in peoples style 1s and 2s on occasion.

Arnold sort of got out of that business and passed on the ring to Eric Sullivan to duplicate and sell @ FQMS.

I would contact Eric and see if he will share the dimesnions of his rings.......they should be exactly the same as the originals.......
