I painted this: Mad Cow 2.6" fiberglass Tomach (changed the fin design) that's been waiting for paint since last summer. 130 stars on the thing. Some technical difficulty getting the chrome paint to work properly and play well with the Oracal 631, and getting the blue and green to adhere, but only 4 of the stars messed up slightly. I'm just going to live with it! STILL looks amazing. It might get a coat of 2 part automotive poly, not sure how froggy I feel yet.

Dang, that is sweet.
 
Today I ordered an AT J250FJ-L from Wildman for my L2 Cert at MMWP. My Goblin sims to 4.2K+ ft. (1st cert choice) and my ****** RIM-66 sims to 5.4K+ ft. (2nd cert choice). I was considering ordering an AT J401FJ-L rather then the J250 but I chickened out at the last moment. The RIM-66 sims to 7.6K ft and that alt. scares me a bit. Maybe I'll man up and fly the J401 later this summer...
 
7.6 k ft shouldn’t scare you as long as it’s dual deploy or JLCR with decent gps trackers. I’ve flown L1 multistages past 11,563 ft. Like any other flight but more antsy to actually recover it. (Because you may not see it land). My L2 cert choice is planned at 7.3k ft.
 
Base white was painted weeks ago. Masked tip and painted black this morning. Removed tape and clear coated a few minutes later. I feel sick. No more rocket work for now. 0509190629a.jpg0509190630.jpg
 
Got the big BBII ground tested yesterday evening. The drogue test, with two 2-56 shear pins and 2.2g black powder, was a pass. The main, with three 2-56 shear pins and 2.0g, was a fail. Good separation of the nose cone but the parachute did not leave the payload tube. Hopefully today I will get the chance to re-run the main with increased black powder. I had wrapped the nose cone and payload tube with bubble wrap to protect the paint during testing.

$20 worth of harbor freight moving blankets and you're good to go. They double as transport padding.
 
Was the paint Krylon by chance?
Rusto... I think it was because I wiped the part in IPA before clear coating. That must have softened the white. But I wiped it all off with acetone. Since it was black plastic I taped the tip and the shoulder. Then painted the white again. Remove the tip tape and sprayed clear over it all right away. Then instantly remove the shoulder tape. Turned out much better0509190741.jpg
 
Lockheed Martin is processing my system integrations and test engineer application for spacecraft design. (up to 4 weeks)

In the meantime I applied to 39 other positions there in engineering lol.
 
Cut fins for a new rocket. I'm planning to fly it at Delamar, but I have 10 days of vacation between now & then...I better get busy.
 
First printed rocket part. It came out better than I'd feared, and it will fly - but I should probably read a little bit from the "How to 3D Print" guide before I print the next one.

Military, civil, or commercial? I worked for the first 11 years of my career on LM commercial satellites, A2100 (now LM2100). If you've got questions I'd be glad to answer them as best I can, though I've been away since 2006.

Looks more than OK from here. What's the spiral for?
