This Is All Bt- 40
Everything here is BT 40. The steel ruler is all I had & may mess up the pics. Let me know what else you need, Bt 30s too? Danny BTW-this is a 16 inch ruler.

Firefox sells a body tube that is dimensionally the same as a BT-40, but spiral wound.
Unfortunately some stupid regulation prevents them from shipping it in decent lengths. I can understand why convolute wound tube has those rules, but this isn't something you'd use to make fireworks. Until that scotched my order, I was set to put together a couple of dozen models based on those Design Book plans.

Here's an early fin unit to fit a BT-40. I also have one of the early spin fin units around somewhere, and will try to find it if there's any interest.

Fantastic, guys - this is exactly what I was hoping to see! As soon as I get a chance, I'll try to to a 3D render of the fin can and nose cones for printing. I can't do the actual printing right now since my printer only handles PLA - nose cones would be rough but usable, but I'm afraid the motor exhaust would war a PLA fin can. Won't have a printer capable of printing ABS until early next year.

You could see if e-Rockets has some Semroc BT-40 equiv. left (or if they're having more made for Aerobee-Hi kits). I bought a few from Sheryl a few months before she sold.
