Chuck,
Speaking of RECOVERY . . . Here is an interesting concept that might bear further investigation .

I am envisioning bringing the "ARR" down in TWO pieces ( AFTER Drogue Deployment ), each equipped with something similar to the above.
It would allow for the use of smaller parachutes, also.
Thoughts ?
Dave
Not bad ideas. With the rocket at close to 400 pounds after the burn the recovery system is going to be quite stout.
Thanks for the links.

For parachutes of this size and strength, something more rugged than a chute release is likely required. Search the forum and interwebs for Deployment Bag techniques (sometimes referred to as D-bags.... )
That's a technical suggestion based on the forces involved. My hands-on rocket experience has a gap between standard dual deploy and burnup on reentry
Chuck,
Once again, merely a "concept" . . . Not the actual "hardware" involved.
I was thinking in terms of reliability of Main Deployment(s), without tangling or potential "impact" of airframe components, plus the ability to use smaller chutes.

Hey Chuck! I don't get around on the forum much but just came across this thread that you started and just wanted to say hi. Good luck with your project! Are you planning to make it to LDRS this year in Argonia?

Chuck,
Obviously it's your choice, but you don't have to dismiss this case just because it 'has a seam'. A simple hydrostatic proof test would tell you if it is usable or not. They you can use it or dispose of it as seems appropriate.
I have a complete 6 inch case that I was given that truly is 'not worth the risk' because the threads are so loose they can engage normally or cross threaded with equal ease [and without damage]. However it makes a handy mandrel sometimes, so I hang onto it.

Speaking of deployment...
I can’t wait to see some build pictures. I’m hoping I will make it to LDRS.Hey Jim thanks for checking in! I'm thinking of LDRS... be fun to watch some rockets fly.
Mainly focusing on BALLS with this project.
Thanks!

Deployment " canisters" that hold the chutes are another optionFor parachutes of this size and strength, something more rugged than a chute release is likely required. Search the forum and interwebs for Deployment Bag techniques (sometimes referred to as D-bags.... )

I was in charge of the chute for our 1/3 scale V2 https://tripolioklahoma.org/html/v2/v2-main.html
I used a surplus 28 foot man rated, patched the holes and rigging, sewed a d-bag to fit the chute compartment, used a 6 foot pilot chute to pull it out of the bag.
It was a tedious but fun project.
We eventually donated it to the air/space museum in OKC.
Back in the day, Mark Clark's company Black Sky, made a pyro actuated cable cutter, that would be more along the lines of what you guys would be looking for
I've got a Jolly, they're cool an all, but they use rubber bands...

Seriously cool hybrid motors there Dave!
Time for L3 my man!

Here's the trailer we'll be using for the launch tower and Rocket Transport System. It'll be 4 ft longer than this one. Levi Seaton is the Launch Pad Technician in charge of converting this bad boy into a fully functional Rocket Launch System:

Chuck,
If the wheel-wells on your trailer are like those in the photo, see if your welder can fabricate some "covers" to slip over them. That way you could leave the tires on, at launch, if desired.
