What did you do rocket wise today?

[wmay78]

Two new projects/scratch builds for recently purchased 24mm and 29mm hardware.
1. Bt-80 short body with delta swept fins and 29mm motor mount.

2. Bt-60 body with trapezoid fins, 24mm motor.
Both Hopefully flying fathers day weekend!

I'm not looking to break any speed or altitude records, so I'm not terribly concerned about the extra drag. It's the 18mm, and I have not flown it yet.

I think I'll put mine on for safety. I have an 18/20 aerotech casing I put in it last weekend with a D24T reload. I never saw it after it hit the clouds but did find it later in the day going to pick up one of my high power rockets. It was straight as arrow. Beautiful rocket Sir!

Thanks- I'll keep that in mind, I have a D24 or two...

Built a Eggtimer Quantum. Fired it up, and i am having issues with it... need to check the solder joints on the optoisolaters per Cris’ troubleshooting guide...

Don't give up, mine gave me a hard time as well. Touched up some solder joints and got it working. I've since built another one that fired up first time.

Oh, I’m not! This is actually my second quantum. My first was given to me as part of the the TRF secret Santa a few years ago, and I was intimidated by it until last week When I decided to finally give it a try. All went well until the very end when I screwed up and put the fet in the place of a rectifier. I fried the board accidentally when trying to remove it and fix my mistake. Cris was nice enough to send me a new part just in case, but the damage was done. I bought a hot air station on amazon, and it worked wonders the second time around. Now, I can get the unit to boot up, but I can’t eat continuity on the rogue channel.

Last night/this morning.
Assembled a Semroc 1/35 V2 from parts from erockets.
Parts were bagged and thrown into the build pile centuries ago.
1.84" dia. (ST-18) tube, pre-drilled nose cone for ballast, pre-drilled tail cone with 24mm opening.
Laser cut fins.
Assembled wt. 2.05 oz.
Don't know if Semroc ever put this into production, but their specs show an 18mm motor mount.
https://www.semroc.com/Store/scripts/RocketKits.asp?SKU=KS-4
Soda can for scale.
Just need to epoxy in some bbs.
Build, build, build!
Laters.

I love that balsa tail cone.

Put the final paint touch on a scratch build BiSix. Not sure if I'm adding to the LPR inventory so my grandson has more to chase down or if I'm succumbing to "stay at home" OCD.

 

[rharshberger]

Prepped my FlisKits Tres for its maiden flight on 3xAT 18/20 D24-7T's, its ready with JLCR, JL Alt 3, FlightSketch Mini for data and recovery. RTF its 12oz. and right at about 1 cal of stability.

 

[o1d_dude]

Epoxied the motor mount into my black/orange Formula 54 from Madcow and beveled the fins.

In the process of ordering a couple of Landru AV bay sleds from Missileworks for my two LaserLoC kits.

Keep working on that, Robert, and be on the lookout for an Estes/Hobby Lobby “Vapor”. One of the two suggested finishing scheme is very similar to what you’ve done.

Thanks for the encouragement. I’ll definitely try this again in the future. But for now I’m calling it done. I masked off the bottom of the rocket, lightly sanded the tape line edge down a bit and then hit the top with a dusting of yellow. (With the light breeze, I think more paint drifted over the fence than got on the rocket.) Here’s the final result:



Still a bit of a sharp edge, but much better than last night. I’m afraid if I keep messing with it at this point, I’ll waste a lot of paint for little benefit, or I’ll go overboard on a coat and end up with the runs.

All that’s left to do is wait for a couple of sets of StickerShock custom lettering I ordered last night.

My grandsons (8 & 9) are visiting for several weeks. Having fun teaching them about rockets! We even made the evening news.

 

[Adam3836]

Got the motor mount installed and fins sanded and glued on the 24mm stonebreaker
Next up primer and paint

 

[Wally Ferrer]

Another one ready for paint, SBR Honest John. I still have the big one to build...

I cut my fins a millimeter short so i created a couple supporting rings for them to rest on. Now I'm just putting epoxy layer after layer and the fillets.

Wood filler in on the fins and body tube for the spirals, sanding, and paint.

 

[prfesser]

Finished masking, and sprayed the undercoat, for the semi-upscale-260-space-booster. Masking is a LOTTA work!

 

[ToneDeafJunior]

I did not listen to my head telling me NO and flew the Saturn V one more time today. Must have tweaked a fin last flight because it corkscrewed up only about 100 feet, turned over and with a 4 second delay... Well, you know. Ruined the Gemini capsule too. It was not a good day for me.

 

[Scrapmaster87]

Almost done CADDing my 4.6" Big Bertha motor mount.... I can't do anything easy...

The motor tubes are rolled and cut, I think I might go print a cropped test section of that forward ring. Need to make sure the threads will print nicely and the PET nut holes come out clean.

Those are 29/360 and 380/1080 cases modeled there.

 

[o1d_dude]

Used my badass fin jig from Badass Rocketry to mount fins on Madcow / RW Formula 54. Weighed all the components as well. Heavier than I thought it would be even without recovery gear.

Played with OpenRocket on the Formula 54 file. I have a long way to go on getting my sim chops up to snuff.

In the lower right area I can see a peace of wire that is not suppose to be their.

My TRA level 1 HPR certification rocket flown yesterday 5-16-20. 57" long, 2.15" Diameter "Blue Angel" (PML Phobos kit) flown to 2569 ft. with an Aerotech H219T-10 motor. Sorry too tired to post last night.

congrats!!! That is an awesome day you had!!

 

[Vdutel]

sanded the fins on my Estes Goblin this morning. Getting it ready for primer tonight after work.

 

[Knuckledragger]

Installed the shock cords on my modified Big Daddy, finished painting the Mars Lander (just have to install the rivets to make the landing assembly accessible), cut the fins for a Leviathan clone, and primered the Big Bertha. Tried launching the BD three times last week but the winds were 15+ and a burn ban in place so maybe today or tomorrow it goes airborn.

that’s already been addressed... it was a strand of loose wire From when I clipped the battery leads down. It wasn’t soldered on at all

 

[Old School Doug]

Finished a quick and dirty Apogee plan file scratch build Bolaero from extra parts. Enough LPRs for the grandson to chase down for a while. Now it's time for "Pop Pop Doug" to build a few toys for himself.

 

[Adam3836]

Did some successful small launches today with the little man
Alpha and jetliner

 

[prfesser]

Masked and sprayed the undercoat on my 3" Aerobee Hi, in preparation for the next color.

 

[Adam3836]

Note to self check launch gear thoroughly and if the clip is broke and your using a cheap rod STOP lol sent my AGM rocket 150 yards the wrong way lol alittle Hike later and got her back

I use the same Husky chest for my field box.

But now I also have a motor box, a motor hardware box, and a launch support gear box (paper towels, dog barf, safety vest, digital scale, strap wrenches, etc.)
