I find it sad that this forum is here and empty. So I made a couple little parts for a rocket build. I don't think they deserve their own thread really, but I'll add more posts as I go.

These are pretty simple, caps for a tube that fits in another tube. The tube they cap off is used to hold electronics for deploying parachutes and tracking. The ends need to be sealed to prevent the high pressure of the separation charge from damaging the sensors. They also need to move freely in the larger body tube so that the tubes can separate.

It was also a little project to practice setup, measuring, and hitting sizes. Other than some chatter marks on one from parting, they turned out pretty decent. Material is 6061 aluminum.

I post all of my rocketry machining projects on The Rocketry Forum. ;^)

Steve Shannon is on here once in a while too.

I'm on TRF as well, but I've been enjoying this place, so I figured I'd put some content in this neglected forum. And TRF doesn't really have a machining section. :)

Keep posting as someone else might start working on this type of thing, and you would be surprised as to what can be adapted from one thing to another.

Thanks for posting, I used to build rockets with match heads and aluminum foil shaped on a writing pen.
That was 50+ years ago.

I have much better tools now.

You could use them to join us on the dark side... :)

Well, keep us up to date on your build, and maybe I will get smart enough to build a rocket.

I use to build model rockets fifty years ago. Estes and I think century was another, built my own launch pad and station. One rocket I built was a sputnik they said it'll never fly. It did and I won a couple awards ,, big deal,, at 10 it was. It was a Styrofoam ball 4" in dia. With four long wood legs ,,matchstick,, fireplace size. Bored center for engine tube it shot well . I enjoyed those years. We even made rocket powered cars do they build them now too.

I've seen a few sputnik style things fly. They tend to do ok if there is enough "stick" hanging down. They act like fins and stabilize it. I saw pictures of one that was a big ball with pool noodles sticking out that air resistance pulled down in flight. Looked crazy but flew well.

There are a few people that do cars. It's against the group safety codes, so you can't really do it at an organized launch.
