Sweet syringe!
Thanks! Unfortunately it didn't work as well as I hoped. Concept was good but Rocketpoxy is thick and my tubing was too small. Even trying to heat it up didn't help much. I was able to use it enough to get the mid and forward centering ring glued in the right place. Going to let that set and then use a stick and brush to do the internal fillets on the fins.Sweet syringe!
Great idea and perfect timing. Now I just need to get a hose clamp for a 7.5" tube.
The fin can is complete. Motor adapter built.

Made a tool to help with the internal joints and fillets.

Was able to slide the fin can in place. Lines up just great. Tomorrow I'll glue everything in place.

I can see where the hose clamp will come in handy. A lot of gaps there.
Cool. I've got a bunch in the garage. I'll give that a shot first. Thanks.There was a guy who did a build thread for a LOC VII. In one of his photos, it shows many many hand "spring clamps". They looked like big clothes pins. He circled them around the body tube. I hope this helps.

Oh, yeah, no, RocketPoxy cannot be injected.Thanks! Unfortunately it didn't work as well as I hoped. Concept was good but Rocketpoxy is thick and my tubing was too small.

Nice fillets. Your doing a very nice job on the build
Woah. I was negligent here, wasn't I? Being in quarantine and having the launches cancelled caused me to lose motivation to build. Fast forward to a few weeks ago when our club surprisingly announced a launch. I finished the build, really all I had left was the electronics bay. I didn't have time for a proper paint job so I flew it naked. I wanted to test my altimeter placement so i used motor ejection for the first flight. Flew it on a CTI J293 to about 1300ft. It's heavy! Around 12 pounds.Any updates?
Flying 54mm motors which have 2g powder in them. Did a test in the backyard to make sure. Using two shear pins to hold the nosecone and keep everything aligned. 2g separated it just fine. I had an 8s delay on the motor.did you add bp for the motor eject? What was your delay?

Here are some pics of the final build and the launch.

i have the paint, stickers and lettering arriving this week. Will probably start priming and filling tomorrow. I’ll post pics of the final product. No spoilers but it’s gonna be super!
I had right at a pound. I debated how much. Openrocket wanted me to add a ton get good stability numbers. I read some articles about short stubby rockets and added a massless come behind the rocket in openrocket which made it more reasonable.How much weight did you end up putting in the nose?
VERY COOL!Just to wrap up this post here is the final rocket with paint and vinyl
