I don't have the rotary jig but I was wondering what your thoughts about using this mpc to produce a dowel. It should produce a 2" dowel 12" long leaving both ends with 1” X 2"square. I don't see why the machine couldn't handle this however I may be totally off base here but you have to start somewhere I guess.
Board Layout 14" X 6.727 X .750
Drew a series of vectors 11.5 and assigned a 1/2 straight bit using 4 passes with a max .138 per cut for a total cut of .41 cut allowing for a .250 overlap for the bit on the ends of the vectors (should yield 12”). I used Randall Newcomb diagram below to get the depth.
In this first diagram ignore the top number it's referring to a safe Z and doesn't pertain to the CW
