New Dobson Spunover


Spunover rim, maple neck, ebony fretboard, detail.

Here are a few pictures of the latest Banjo in the workshop. Please click over any image to enlarge.
It’s a fully spunover rim with a Dobson ring tone fitted over. Both spun from a single ring of brass and have no joints at all. After extruding, both were nickelplated as it is all the hardware, all made at Rickard Banjos.

The internal wood ply is a single layer of curly maple approximatedly 1/4″ thick and was inserted and glued into the spun over rim after the nickel plating process.

The maple insert is yet not finish It requires several coats of a clear catalized varnish. The neck is a “5 ply construction”, a central laminate of maple was glued up with with two contrasting plys of dyed black pear wood between the main neck pieces of curly maple. There is no truss rod but it has two strips of carbon fiber for additional strength.

In this rim construction the tone ring sits on top of the spun over rim assembly, like it did on the original Dobson’s rims. The tone ring has a slightly flatter profile, compared to an original Dobson tone ring, to accomodate the fiberskyn head.

  1. Beautiful!!!!!! I have ordered a spun over rim from Brooks Masten…Perhaps in the future I will get a hold of one of yours…In the meantime I have a Dave Ball Banjo that sounds lovely and has a beutifully carved neck and heel…I would like to replace some of the hardware however with raw brass parts…It has a block 12″ rim of padauk wood…and a one piece rosewood neck…I would like to replace the tension hoop with a raw brass one,as well as replace the shoes[which are “L-shaped”]and hooks wih raw brass “Ball-end” shoes and hooks…The rim has 26 shoes and hooks not including the shoe and hook assembly for the tailpiece…I currently have a brass fielding tailpiece which looks and sounds great….Please let me know if I can do this…I.E. #1 If you have the Parts…#2 The cost…I love the looks of your joint venture with Kevin Enoch….Sincerely,Kevin Maloney
