And it rained… and hailed…
So why not go up to the launch site with freshly topped off swamps…
What did you do rocket wise today?

Last night, I used JB Weld to epoxy on the AeroPack 38mm retainer to my LOC Nuke Pro Maxx. I bought the 38L version and it was a VERY tight fit! I did a test-fit and had to get my BIL to help me pull it off the motor mount. Was tempted to not even worry about the JB Weld, but decided it was probably for the best to use it.
Just finished putting the first fin on that rocket and am doing some shopping for the Freedom Launch in September.

Other two fins are on and I was prepping my 66" Spherachute for the JLCR and got some help from my little girl, Lagertha:

Got my 1/5 scale-ish Sandia Dualhawk in the air. H175 to F31. Keeping it low because the wind direction was bad. Proton says 1741’.
Low?
So we will be able to finally meet in SC?

Well the original plan for this was an H255-H13, which sims out to about 4600’. So yeah, Low.
Keeping these (essentially) midpower two stage sounding rockets to only about 2000’ is actually a challenge.

Possibly! I won't be bringing the Maggies and all my Schiit to SC, though. Just my rockets and wife.
Progress is being made...

It may not be a big deal to you, but I edited my signature here on TRF! And that was a big deal for me. First time its changed since 2017
(other than changing the year of course!)

Charles, I got good staging pics...give me time to get them off the camera.
I had a crap day. First flight was the 3" Goblin on a G53, CR at 400'. Perfect. Then "Expendable" lived up to its name. 2" dia, 45" or so. F52C to about 1800' CR at 300' but it got pushed hard while in freefall. Searched the rest of the day for it and never found it. Has the JLCR, Astrocam and Estes altimeter on it. Watched it come down just over the trees to the north but still couldn't find it. Will probably look more tomorrow.

Made a pair of over-the-top chutes for my F-79...
Started hearing rocket voices...the beginning of the rise of machines...

I think the photos are great.
I’m sorry for your missing rocket. The grass on the other side of the tree line is surprisingly tall in spots. I fly with some kind of tracking on anything over about 1000’. Even just a beeper with directional mic on the ground.
Thanks! That was a fun flight to watch.
I stupidly didn't put a screamer in it and I think I got more altitude than I expected too (and it definitely didn't turn into the wind at all). My son snapped pics as it was dropping and I got a glimpse of parachute and from what I can tell, it's probably very near the road or over it; further out than I thought. Could be in that tall nasty crap too; which I spent plenty of time in, but perhaps not enough. At least now I can probably get closer; go there tomorrow, line up the bearing on a compass and march to it (I hope).
I will never use another neon green parachute in the summer

Yeah, some colors go better against snow.Thanks! That was a fun flight to watch.

I recovered a couple of rockets from over by the road, and the far side on occasion.
I was inspired by an earlier thread by @lakeroadster seeking to identify the M1147 Tank AMP Round (I think the thread was taken down). Garnered some better details and measurements from a pictured captured from a video...
Anyway, designed and 3D printed parts last night and CNC milled fins this morning for my version 1.0 (version 2.0 is already printing). BT-80 + BT-50 model w/ plywood fins. Decided to make the fins fold on this model but not sure if I will make them spring / rubber-band loaded or if I will just fold them out for launch (I doubt I will do a tube launch).
p.s., in mock-up below I did not cut the BT-50 tube to length.
Simulated in OR and it looks like it will fly well on anything from a C5-3 to an E12-6.

Today, I finally glued up the fin can for my L1 bird that I’ve been procrastinating on for the past year. 4” LOC Goblin
I tend to overthink things and psyche myself out to the point where I avoid even starting. But here we go! Epoxy fillets curing now.

Epoxied the fins into the fincan on my LOC IRIS 3.10" 38mm. Using stringers on the MMT to cradle the fins tabs in a valley of epoxy. Seems to work well. Next are internal epoxy fillets on the inside of body tube. And keeping with the design-no external fillets.

Nice flight!
Got one Tin Tin rocket fin glassed and out of the bag, so while I was on a roll, I thought I'd get another one done!
Second one will take longer to cure as the evening chills from 20degrees C down to about 15degrees C in the next 3 hours or so. Will put a heat lamp on it if it drags on too long.
Using neon-yellow rip-stop as my "poor man's peel-ply" again, and it worked perfectly fine when removing it at the F/glass leather-like stage. The wadding from the recycling shop soaked up the excess epoxy bleeding through the rip-stop and didn't stick at all to the inside of the vac bag. Re-using the vac bag for all three fins.

Nice and tidy!
I see. I forgot to account for 2 stages.

Wow, amazing photos. What camera are you using? Any tips for novices?
Canon 80D. High shutter speed, AI servo with a group of focus points. Burst mode and turn off any lens stabilization. Practice, practice.
In other news, I found my lost rocket just now!!

Hurray!!
Dig, I'm afraid I've lost track of your name. Didn't put a tracker on it, I guess. If I post those photos elsewhere, whom should I credit?
