got this Idea from someone else on the net. I modified his idea. He had the cutter mounted on the side which meant you had to take off the drill attachment. I mounted mine on top so it can stay mounted when using the drill. which meant I had build a new banjo. Mine was too tall when the cutter was mounted on top. It works great. It will cut rings a bit over 1`` deep.
I am trying to come up with an idea on how to move it incrementally. It seems to be better to move the head stock as it is touchy to get the cutter square to the ring . If anyone has any ideas please share
Thanks
Al

Make a piece with 2 pieces of steel in a cross to fit in the slot in your banjo and between the ways.  Use 2 bolts instead of 1 to keep it square.  I am assuming the whole banjo slides in and out to make the cut.

Back to the beginning,
I'm guessing your trying to cut equal sized rings for segmenting.
I do this on a bandsaw due to less wast and I find it easier.
For your method of slicing with a parting tool, here are some suggestions.
Use a thinner parting tool, I would use a 1/16" or 3/32" tool if possible.
The tool rest,
The easiest way I know of is to cut a piece of wood which is easier or metal, that has the equally spaced slots that fit your tool of choice. (think box joint) You can cut slots for whatever size ring you're cutting. A template for 1/4" , 3/8", 1/2" rings etc. The template can be attached to the toolrest or an assembly that can be mounted in the banjo directly.
With this method you only need to align the toolrest/banjo once. Once you cut a ring, you simply move the tool to the next slot and repeat.
