fin can

For day job stuff, we frequently anneal 3d printed parts (plus stress relive machined aluminum, heat treating formed parts etc...). For rocket stuff, things like fins I anneal, I never bothered to do it with av bay stuff, or drill jigs. I have annealed using an oven and even used the dark car...

OK… So I’m finishing up the fin can portion of my LOC 4in AMRAAM build and I’ve run into a bit of a dilemma. Will epoxying the top CR/recovery eyelet to the fin can by applying an epoxy to the inside and outside of the MMT(inside radius), then epoxying CR to the inside of the coupler going to...

Interested in hearing from anyone who might have constructed an Estes Vapor #7294 for dual-deploy recovery. I have an eye towards building one to allow for more practice with dual deploy at our club's field, which is currently low and mid-power only. I know I'll need to construct an AV bay, and...

Several people have posted fin can generators. Most of them cannot generate round fillets. I thought, "How hard can that be?" Well, two weeks later I finally have something to share! The attached script lets you design fin cans. A "fin" is composed of up to three trapezoidal, simple fins...

I'm in the design phase of my level 3 certification. The base airframe will be a LOC Bruiser EXP. Unfortunately, I think my kit was a mixed bag between versions which means my fin situation looks like this: This obviously isn't ideal. Now, I do have a 3D printer, and the obvious solution to me...

I'm working on a project--and hoping to fly it at Bama Blastoff II in October. I'm trying to build a mach-capable rocket using a carbon fiber airframe, and a 3-D printed 38mm fin can from Additive Aerospace. My experience with 3-D printed components is limited to low power flights. If it...
