What did you do rocket wise today?

[Wayco]

Glued an anchor rod in the 7.5" Tweety bird nosecone. I need to add about two pounds to the top of this rocket, so I can fly the 54/4000 Loki M1378 Loki Red in this cluster rocket.

Brass rod trapped on a 2 ft. piece of 3/8" allthread:

Tweety birds NC is over 3 ft. long, stuck in a 5 gallon bucket of ice water:

4" hole in aft end with an extra length of allthread attached:

I added about a cup of West systems epoxy into it after shoving the rod down.

This rocket's next flight will be at LDRS-38 in Argonia, Kansas. Two J430's, two J250 skidmarks three seconds later, and an M1378 Loki to get it going off the pad.

First flight was at last years LDRS in California:

I printed what might be just a fancy nosecone.

Or the Bat-plane.

Or the Bat-plane.

The black PLA makes it look kinda Bat-ly, doesn't it.

I'm hoping to balance it so that it will 'Fall With Style'.

Time to queue up a 1/72 Atlas V 412.

Finally got around to building rafters in my office at maker space, nice to get the rockets out of the way instead of constantly moving them to work on others.

That is an excellent idea if I ever saw one! KUDOS

Got my NAR L1 certification (yesterday) on an AT H115DM in a Madcow 4" Patriot! Woo hoo! Happy MDRA member!

 

[jqavins]

Congrats!

 

[wrad]

finished sewing the gores on my first non flat chute, just the lines to go now.

 

[Flyfalcons]

Ordered some tubes from a member here to begin repair work on my cratered Nike Apache booster! Then talked to Madcow and found out they don't make the interstage coupler transition anymore......sigh.......I see fabrication in my future.

Started a Bull Puppy build

Painted the Gemini III stripes on the Lifting Rocket Cargo Bay... see build thread below for more data.

Started seriously contemplating getting my L3. Going the scratch build route with a 6" upscale of a rocket I designed back in 8th grade (76').

But before that build, I need to hone my electronic and dual deploy skills with some smaller birds. This is gonna take awhile....

Finished reading "Handbook of Model Rocketry" that got sent to me on Dropbox.

Had my first go at making fin fillets using epoxy putty. Very happy with how they turned out. Used these tools:

https://www.amazon.com/gp/product/B0758CW7ZG/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

Dipped the ball end in solvent and smoothed out the fillet. Easier than a finger. Got the fillets done on an Estes CC Express and a Launch Pad ASRAAM. Should be ready for primer tomorrow.

Congrats!!!

Congratulations!

That looks like a great way to get perfect fillets with those plated balls. Thanks for your link to them. What solvent did you use?

ShotokuTech Rocketry Update June 2019. Two rocketry projects in the works at ShotokuTech. Work is well under way now on Project X and the anniversary of the Apollo 11 Moon Landing is just a few weeks away.

My post of what I did today isn't going to be anywhere near as impressive as all the esteemed posts that preceded mine. I'm amazed at what you guys build and do with rockets.

I placed the third strake fin on the 2.6" body tube Sentinel upscale this morning. Here's a photo of the second strake being installed about 10pm last night with the rocket in the fin jig.

The jig works great.

I've never seen fins so perfectly aligned.The photo sure doesn't reproduce that very well, LOL

If you post about rockets, it belongs! Little rockets, big rockets, simple rockets, unnecessarily complex rockets, painted rockets, naked rockets, we want to see them all!

 

[jqavins]

unnecessarily complex rockets

Hey! why you pickin' on Neil like that?

 

[SierraDrinker]

Rebuilt a sled for my 2" fiberglass Frenzy XL. First one couldn't fit a 9v battery. Lesson learned: use smaller batteries. Also lesson learned: 2" rockets are a pain to build if you're trying dual deploy for the first time.

 

[jqavins]

Also lesson learned: 2" rockets are a pain to build if you're trying dual deploy for the first time.

And since you'll never have another first time... But, as the say, smart people learn from their mistakes and wise people learn from others' mistakes, so it shouldn't be a total loss.

Bollocks! Complexity of my rockets is completely necessary in service of... ah... lemme get back to you on that.

Then again, if you're trying to work towards something like this...

Maybe after I learn how to design my own altimeter. Considering a struggled assembling an Eggtimer classic with this build, I have a long way to go.

Ah, Yes you do spot DUNE in the photo Liv3mind.

I have all but the last couple of Dune books also.

I've been a Dune fan since the middle 70s.

"I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when my fear is gone I will turn and face fear's path, and only I will remain." - Paul Atreides
