Too sick to do much in the shop today -- but a little progress nevertheless.
The taller hatch broke away from the bed about 20 minutes after I posted the picture last night. I cut the model into two pieces and -- becuase I knew I was going to have to do some drilling and sanding to assemble the hatch -- I switched to carbon-fiber infused PETG.
Then I did this
I installed the rigid rotator/fly-wheel/bearingless disappointment in the nose cone. I put in a plug cut from a scrap of packing foam, and poured in a few ccs of Gorilla Glue. I painted BSI 15 minute epoxy on the inside surface of the cone, installed the flywheel, and then sealed the gaps with thick CA+kicker (my next HPR is going to be assembled without adhesives)
This is easily my most stupidly over-engineered/over-thought rocket project to date. It is taking WAY longer than I'd budgeted. As I type this, I can see my dusty soldering station and the boxes of parts I've been collecting for a non-pyro dual deployment mechanism, and the multi-materials upgrade for the Prusa (still in the box), and the partially assembled low-vacuum chamber, and the parts for a catadioptric telescope, and the projection lens I was going to convert into an anamorphic camera lens adapter, and the parts for a heliospectrometer...and...and... >sigh<
