[TCML] Primary support "advance"

["Jon Danniken" <danniken@xxxxxxxxxxx>]

I'm making some primary supports for my next upgrade, ready to notch them 
out with the router, and I am wondering how you handle the "advancing" of 
each turn.

With six supports, and 1/4" tubing, each support location will have a 1/24" 
radial difference from it's predecessor.

The two obvious ways to handle this are one, to make each notch by advancing 
the jig 1/24" for *every* notch, or two, by making all six of the supports 
identical, and varying each support's location on the plywood "donut" 
supporting the primary and supports.

Which method to you do?

The last time I did this, I remember advancing each one by 1/24", but as I 
don't (yet) possess a ruler graduated in 1/24", I can't for the life of me 
remember how I achieved this.  This method would require changing the jig 
for each notch.
