Okay, I went and bought a Harrison Fin Jig along with the 24mm and 29mm mandrels.

Dan was good to work with and has excellent service.

Shipped on Monday, arrived on Saturday (29mm mandrel will ship this Monday).

Interesting gadget that's for sure.

I guess I had better build a rocket and try it out.

Now that I have one of these devices I am awaiting the appearance of THE Monolith before me which will signal higher rocketry beings (Hard-core NAR competitors? Internats fliers? Elon Musk?) that I have advanced up the rocketry evolutionary scale.
