For an update to this post I got my MiterSet about a week ago and used it yesterday. It is one of the slickest jigs I have ever owned.
The concern here has been the slot width fitting the Miter gauge. Don't worry about the "T" bar miter gauge, if the "T" part is on the end of the bar then there is no problem as the center of the bar is where the jig goes.
The Slot is milled .733" for the Shopsmith, and will fit most other bars, my Bosch "T" bar fit, Incre 2000 fit, Craftsman fit , if the bar is worn or a tad small you just have to shim it to one side with a calling card or thin shim.
It takes only about 5 sec. max to set the miter gauge. I set up for a seven sided polygon and the cuts came out perfect, it took only 5 minutes to have it cut and glued up.
The only math required is to use one of the formulas above to set the radius, to determine the length of the side.
I found that working in metric was easier to set up the stops on the saw to get an accurate stop setting, try setting a stop at 3.462" sometime as apposed to 8.79 cm.
For some reason the 1st picture sisn't load so now it is last showing the Bosch "T" bar miter gauge.
