Cut something like this out of cardboard - circle (I usually cut a hexagon or an octogon) has diameter of body tube, fin slots are shorter than half span.

Works even for HPR rockets. Only problem is that you have to cut another "jig" for mostly every new rocket.

I've made Jim Ball's Fin Alignment Jig. I love this thing! I used a 1/4-20 t-nut and all thread for mine. I've made adapters for 29mm, 38mm, and even a 3 X 24mm cluster.
Check out mine here: Fin Alignment Jig
Nice job Mark. There's a lot of satisfaction to be had in building and then using such things.
I might be mistaken, but I think Estes used to make a small fin jig. It was plastic, adjustable for 3 or 4 fins, and could be used with just about any kit Estes was making.
