Had our first club BoD meeting for the year this evening 3 hours discussing the years plans over Traeger'd pizza.
And not trying to start a glue thread here but as you can see in my prior post the fin can fillets are nice and clear. But one of them went on nice and clear then an hour later kicked off a little strange and it's pretty milky with tons of micro bubbles.Look into T-88 epoxy, much longer cure time but lower curing temperature.
Gotta love Eddie. Well, except for the wind.Today there was a meeting of the faithful in the shadow of the Neil A. Armstrong Flight Test Center
And to address my little conundrum I went online and did a bunch of research. Temperature and incorrect mixing technique with the little stick seem to make the most sense. Next batch I'll make sure the adhesive is a little bit warmer and that I take it easy while I'm mixing and not introduce a bunch of air in to it that can't escape.And not trying to start a glue thread here but as you can see in my prior post the fin can fillets are nice and clear.

As you can see in this picture one pot is clear, like all the others are, and the offending one obviously isn't. I did exactly the same thing for every pot and every fillet but for some reason this one went off the reservation. Not sure if it kicked off too fast and trapped air in it or what. But I've never had this happen before I'm really careful with this stuff and don't mix up huge batches of it, mix thoroughly, watch the temperature do a few Hail Marys blah blah blah. Not sure what I did wrong. But something went sideways.
One of the things I really like about the various System 3 products (like T-88) is that they tend to shed any bubbles fairly well. One caution--the curing time on the T-88 is usually far longer than what it says on the box. That's usually fine as long as you don't plan to do three sets of external fillets in 3 hours.And to address my little conundrum I went online and did a bunch of research.

I decided to get out the Saturn V kit I started building 3 years ago. Abandoned the 24mm MMT and paper rings. Cut new 3/16 plywood rings with 29mm Center and 4 x18mm outer mounts. Not sure yet if I’ll do electronics bay or simple motor eject.
Sounds like a real PITA. I admire your dedication. And I wonder if you've considered making a heated curing box.I got to have a heat gun and a small space heater pointed at me while I'm mixing and filling because I can't let the temp go down below 70 with that 30. Slap the stuff on cover it with foil and crank up the heat and go have a cup of cocoa. Then babysit for an hour with the laser thermometer trying to keep it between 80 and 90°. Then on to the next in 2 hours.
This launch was held out near North Edwards. A few miles east of California City near a place called Aerial Acres. No 'facilities'. No vendors. Just a few peeps launching rockets. Mojave Desert Advanced Rocketry Society. A TRA Prefecture.gdjsky- just wow. Best report ever. Sorry bout the FL, but...if ya gota go? In Flames!
Where in Mojave do you shoot? I'm familiar with a LOT of the dez out there (x-dirt biker - Charlies Place, Husky Hill, Red Mtn, Domes, White Mines, Spangler, etc....). Miss the hills and pucker bushes.
My folks lived in RB a long time (Beryl and Amethyst across from the old Von's market and Big D burgers, lived at Ave. G, and Prospect Ave, etc....way many moons ago) . I know that spot well and all the local surf breaks. I'm in Az. now stuck in the mountains. Sounds dumb but I miss Ca. (when ya get out of the city.)
Great pics/report and thanks. I lived it. Thank you.
Yeah another consequence of CA's overpopulation and climate change causing dry conditions (amongst other things). No places to launch LPR/MPR. Everyone *thinks* it will cause a fire. Ummm not LPR in a school yard... but then there are airports everywhere. The is one location in all of LA Country. Run by a guy that is a little king. There is NOTHING in OC. Mile Square Park became 3 golf courses. There is ROC out in Lucerne Valley (2.5hrs), my spot out near Edwards (2.5hrs), DART in San Diego (3.5 hrs) and Holtville in S.D (or is it Imperial?) county (4.5 hrs). Finally TCC which is like 7 hrs drive. The last two not worth it unless a multi-day launch.I used to launch LP/MP at Flagler Park back in the 70's. Beryl and Flagler. Right below where they filmed the original gone in 60 Secs. Worked at Bob's Bike Rack and Hobby. Largest bike n rocket shop in So Cal. At 14 I was living it there.
