Re: Vacuum tooling for composite construction

Looking great.

Did you use kitchen towel as a breather layer?

Make sure you have a good mask and gloves when sanding the carbon. That stuff is nasty!

Re: Glad Wrap Rocket

Some interesting research on the use of 3d printed ABS cores with carbon fibre laminate:

I should probably start a new thread to explore this further.

Re: Glad Wrap Rocket

That’s pretty sweet design. Those fins make me want to try building a set of diamond beveled fins using a 3D printed core covered with fibreglass and sending them screaming off on some minimum diameter build... I have started experimenting with 3d printed fin cores for a mid power project. I plan t...

Thanks. My camera has been out of action for a while, so it was nice to get some pics again.

I think my reflexes are getting better, because I didn't need to delete too many shots.

Re: Derek's Level 2 Build

Quick update. The end of this build is finally in sight. 2ml centrifuge tubes arrived.

Thanks Mat.

I went through lots of ideas, but the narrow mid section reminded me of a bee or a wasp. So settled for that.

Unfortunately its cold and wet here at the moment, so not great painting weather.

I decided to get some of the painting done before assembly as it seemed like less hassle for a rocket...
