What did you do rocket wise today?

[tOD]

Did some crosshatching of fin roots and motor mount then dry fit the fins and tacked the centering rings in place with CA. Next step will be to apply Rocketpoxy fillets on the outside of the fore and aft rings and interior fillets on the middle rings. Mach 1 Speed Demon BT60. I want everything to fit as tightly as possible so I don't get a lot of epoxy leaking when I inject the internal fillets.

Put 3 coats (and, yes sanded) CWF on new bigger, thicker fins for the Tube Stack. Installed MMT also.

I flew the Congreve today on an E12, and it was stable for most of the flight. It pitched over at the very end of the burn, so I might make a new nose cone with slightly more nose weight. Overall it flew better than I thought.

Well, I guess if you got back 3 of 3 then the rest is secondary.
Y'know what the difference is between talent and skill? Talent is native, where skill is acquired through practice. It's best to have both. As for me, I seem to have an anti-talent that I don't believe practice will ever adequately counter. I'd be totally lost without jigs.

Saturday I blew the best chance all year for painting. A weekend, 60º, and sunny with low wind. I'd had a few other things I had to do and thought "The last time I saw a forecast, Sunday was supposed to be as good or better than Saturday, if the 30% change of light rain gives me a window, so I'll get some stray bombing in tomorrow." Sunday was in the 40s and drizzling all day. Damn my lazy backside!

That flew pretty true! Good job.

As mentor for the USYD Rocketry Team I evaluated a payload PCB design they had done and provided feedback.

It's nice to be doing some rocketry.

I finally finished editing our club's latest newsletter issue:

Well I am going to need a larger launch pad....

It's not completed but a few good steps closer. It seemed a little smaller once on the pad. Now I just need a friend or 2 to get L1 certified and help at the pad.

I posted my triple E12 cato in the Liftoff thread, then started building a clone of the Viper 3 that was destroyed.
Finished up posting the launch report on "Arizona Isolation launch #2:
https://www.rocketryforum.com/threads/arizona-isolation-launch-2.159094

Also got back to work on the Frenzy XL, and put a coat of primer on an old Vagabond that I'm restoring.

Ordered my EggFinder Mini sled nose cone mount (the Works) and some miscellaneous support pieces from LabRat.

Reacquainted myself with peeling glassine off the fin can area of my LOC Precision LaserLOC 2.23. I’d forgotten how enjoyable a task that is...right up there with sanding but it builds character.

Sorted out my latest collection of rocketry parts & pieces and put them away where I will (hopefully) be able to find them when needed.

Fitted the motor mount of the Micro Mamba and but still have to wipe the fuselage tube down with alcohol before epoxying it in place.

Glued the launch rod tube on my Luna Bug.

Finished scratch-built Quark, been knocking out the non-sanctioned tumble/featherweight kits from my youth with junk parts and scraps. Low stress fun and good practice. Along the way, I realized I could easily build a BT-80 upscale "Strange" Quark. 29mm mount from Apogee cut short. Fins will be 1/8 balsa laminated, either 1/64" G10 or 1/32" plywood if I can do it w/o a warp. Lack of body tube space is an issue and I may need to take a little shoulder off and hollow cone a bit for extra room. Long shock cord due to larger ejection charge in 29mm motors and small recovery area. I think this has been done before but it's been enjoyable. For a twist, making TTW tabs separately. Estes retainer for cheapness and lightness. This one may come back unlike the original. Semroc BNC-80G4 or 80AH, whichever looks best. The G4 with a slightly blunted tip looks closest. FL blue nose instead of periwinkle. Currently 78 grams - going to be a light model for mid-power.

Hmm, wonder if burnout of the motor caused a slight destabilizing loss of forward mass. Either way, great rocket, good flight (you even painted it!)

Cool! That's a fun one.

Yesterday, I was at another launch at Heroe's Park. Since it's about as calm as it gets in Omaha, I flew a bunch of BGs. Today, I ordered a binge of G. Harry books off eBay, including the 4th, 5th, and 6th editions of the Handbook of Model Rocketry, the Model Rocketry Manual, and the New Model Rocketry Manual. I'm amused that somebody is trying to sell Starship Through Space at $150. I picked up my copy at a second hand store in Onawa, Iowa for either 50¢ or $1back in cicra '88 before I knew what it was. I'm not so amused at how eBay messed up their PayPal function. Yesterday and today, I'm printing out some close enough to Allis orange, redesigned bar-nuts to replace the cracked ones on the "Gleaner" Omni-Pad.

mach 1.1 something. Accl pc chip said 896mph. 14k

 

[Doug Holverson]

So why did G. Harry write both The Handbook of Model Rocketry and the Model Rocketry Manual? Wouldn't one be redundant? Then there's The New Model Rocketry Manual to make it even more "redundanter"....

It's like using altimeter deployment, with a motor ejection charge for a backup... and a second altimeter?

 

[jbsommerfeldt]

even more "redundanter"....

haahehaaa

I was eyeing the same tubes at home depot. As my wife stepped up she said "Thinking about building a rocket? " Boy, does she have my number.

That looks awesome! How did you make nosecone? (I'm trying to figure out what the circles are on it.)

 

[Joekeyo]

Finished filling and sanding fins for Tube Stack. Put "rivets" (poked holes for glue to flow in) on fins and BT. Converted plastic transition to bulkhead.

How tall/wide is that thing?

Finally got a good coat of Rusto enamel on Sharon's Mach 1 Excellerator:


Did another set of fillets on the Frenzy XL, with the leftovers going on my Nike Smoke.

I have a build thread going in the Scale section:
https://www.rocketryforum.com/threads/1-4-scale-viking-7-sounding-rocket.156896/
I fabricated or widled everything by hand, everything besides the 98mm cardboard mmt from madcow is from Home Depot, Lowes, or Menards. A prime example of what more time then money can bring to the table.

The circles are some low spots I want to build up with one final layer of bondo.

How tall/wide is that thing?

It's a 1/4 scale Viking 7 sounding rocket. So officially its 142.875" from the base of the booster to the nose cone tip and 8" in diameter. Then the retainer will hang down about 1.5" so overall 12' 3/8".

Craigslist score. I have never build an Alpha and I like the look of the Nemesis.

Thanks! The motor is in front of the CG, so that is what we have been thinking. I'm going to fly it with more nose weight and see if that fixes it (mine is not made from sheet iron, so it's a little lighter in the nose than the original).
