Fin guides

[Normzilla]

Anyone make those laser cut fin guides?

I'm looking for 3 and 4 fin templates for 3 and 4 inch body tubes.

Thanks all

Not what you're asking, I know, but you could visit https://www.payloadbay.com/page-Tools.html and print one on paper, glue it to a foam board from a hobby store, cut with a matte knife, and voila. I've done all of my rockets this way, from 2.6" tubes to 8" FG tubes.

Not the same thing, but these have worked very well for me.

Nat at Upscale CNC. He has done quite a bit of work for me and he does the fin jigs for MAC Performance and Mike will likely tell you as much if you email him.

Just hit Nat directly and he will help you out.

I've never had good luck cutting my own out of foam board. Tried several times just never got it down. So I designed me some guides in FreeCAD and had them 3d printed at 3dHubs.

Just curious would you be willing to share your designs?

I use the 1" thick foamular board. You can buy it from Home Depot for $6. Comes in a handy 2'x2' sheet. Super rigid, but easy to cut with a utility knife. It's thick enough to not warp or bend when using it as a fin guide. Good stuff. I used it with my 8" diam. rocket with 7" fin semispans.
