Review my motor mount of insanity

[Scrapmaster87]

In short: This is my motor mount nearly done fabrication and in mock up, I'll be glad to hear any input on my work.

In long: This is going in a 4.6" big bertha upscale. Those are 4x 29mm an 1x 38mm, a 29/360 and a 29/240 can be seen installed. I'm having good luck using those speaker terminals for ejection charges, so I figure they'd be fine for air starts. That plate they're mounted to is removable anyway, so they can be changed lated if needed.

I'll be using 4-conductor headphone jacks as my breakaway to the e-bay. Of which, I'll be using an eggtimer proton for 4 airstart channels and 2 recovery channels with an eggtimer quark as backup (2 channels). I'm using my twist-detent lock for quick service of the e-bay, but that's another thread.

So please, pick apart my work while I can remake/reprint anything. After a few high impulse H and I flights, I hope to use this for my level 2.

Some nice ideas and craftsmanship there.

If you are planning to cluster for L2 it is not permitted by Tripoli. Not sure about NAR. Tripoli consider it a complex rocket, and clusters/staging are not allowed for certification flights.

I phrased that poorly, I intend to use the rocket itself for cert, not a cluster.

No worries

Looks nice! So you push the ignitor leads up through the holes on the bottom plate, they run up through the conduits, and then you plug them into the speaker terminals?

That's the plan, that's a scrap lead in the picture. It pushed through nicely and I didn't need hemostats to get the leads plugged in. Until I started this project, I never thought I'd ever be using my brakeline bender again, especially for a rocket.
