I agree with Chris but everyone should make this attempt at least twice though.  The first if it was like mine, was a bit (ok quite a bit) of a Mess.  Wear old shoes,  clothes, and glass it someplace that you don't care about to much.  ;D

I spent the last couple days putting this together. The fin design changed a little. The rocket so far comes in at about 24 oz. 15 of those are in the nose cone.

With 3 centering rings instead of 2 in a rocket this small, I installed the middle ring first, then glued the forward ring on the motor tube (with shock cord) and installed that assembly from the forward side of the gody tube instead of the aft.

There is 8.5 oz. of buckshot in the nose, so to make sure it doesn't go anywhere, I first drilled a 1/4" hole through the sides of the nose cone, then ran a 1/4" dowel through it. The buckshot/epoxy mixture then surrounds the dowel so the weight isn't going anywhere.

Note the CG in the full rocket photo. this is basically a 32" long dart.

Here are some pics. I am hoping to bring it in to the Jan 10 meeting, if work doesn't kill me.

Hey Evan,
Your rocket looked great and would like to see your finished touch up. It would be a supersonic model. How high are you planning to go for?

It is probably transonic. I doubt that it would exceed Mach 1, but it will come close. However it was designed more for altitude. It is heavy which slows it down but at the same time gives it more momentum.
