I machined the mounting ring and tray bracket last night. These two parts weigh 12.5 grams.

Nice work Chris.
Hope this heatwave helps to dry out the Playa soon.
That's dead sexy, Chris. Can't wait to hear how it flies!I also machined a motor retainer/recovery hard point. <snip>

I finally got back to work on this project today. I machined a jig and then drilled the screw switch and camera holes into the nose cone.
I also machined a motor retainer/recovery hard point. I'm going to glue a ring of coupler into the booster even with the end of the motor. This plate will be screwed to the closure above the ring. The recovery harness is attached by inserting a hardened dowel pin through the loop. The screws keep the pin in place when it's not under load.

It's projected to hit 35k' on an M685.

What's the breaking strength on that pin? Would love to have something like this, but I'm worried about the pin breaking on a suboptimal deployment.

Do you have the 75/7680 case in hand? My local vendor has plenty of 6400 cases, 7680's not so much...

Chris can attest the kevlar cordage will *likely* fail before the anchor point.

Very slick idea with that hardened pin through the sewn loop. Easy to remove/attach and super low profile. Like the isogrid style weight reduction on your bulkhead too :wink:
