3D Printing Fin Bevel Jig

[thzero]

After search around and looking at various RocketryForum articles, blogs like JC's Rocketry, etc. on beveling fins I ended up printing myself a jig. Here are the results for a BOSCH RA1181 router table.







As someone on another thread asked for the STLs, so I threw up my first Thingiverse creation:

I'll have to get around to turning the face plates from OnShape to OpenScad so that they can be customizable.

Fantastic, thanks!
Was leaning towards square edges on my Wildman AGM-78, but thanks to you I think I'll try beveling (testing on scrap first, of course).

This is excellent!

Yeah, definitely practice first... I got go fever and munched to fins. Thankfully I had just enough material to cut out two new fins!

@thzero - Any thoughts on sharing your design file to customize the angle?

Used the tool to bevel some 3mm fiberglass fins, worked pretty well. One direction is better than the other. Probably need a better guide tool for doing the reverse direction.

Hadn't thought about it before because it wasn't built in OpenScad, but turns out I can enable it in OnShape to be exportable and also adjustable.
