What did you do rocket wise today?

Yesterday morning I built a fin jig out of some 3/4" Baltic Birch cut offs I had laying around. Yesterday afternoon and today I glued some fins on two different rockets I'm building, a scratch Arapahoe and a Quest X-15. I can't believe that I didn't build one of these years ago.

Well it was actually yesterday but,Got my lvl1 cert @ havoc our national launch day. only got 2 flights in but SO stoked. Apogee Zephyr preformed outstandingly.

Congratulations.

Congrats!

More prep work for a future build.

I'm so stoked about how great papering fins worked on my scratch build hammerhead that I decided to make some centering rings using the same technique.

The balsa breaks when I try to cut delicate centering rings on my jigsaw... maybe the papering will be just the thing to prevent that?

We'll see.

This is what I did today (or at least finished today.) 520 grams without parachute; should fly well on an E-18 or better. It's been sitting in my build pile for years, but I finally decided to build it for a school presentation that Zia Spacemodelers is doing at the end of this month.

Very nice! I've got one sitting in my office that I'll be starting on in the next few days. Seriously considering turning it into an L1 cert project.

Flew my L1 on a Pink Crayon...one I had built for my daughter and a Red one for my son, the red one died on a G76-4G (delay too long for a 500' flight) so an H128W in the Pink one for my L1, the pink one died a year later on a G80-4W with altimeter ejection however the nosecone failed fully come out and the chute failed to deploy, both are rebuildable and eventually will be, love my Crayons as do my kids we have over a dozen in sizes BT60 (at least 6 Estes), BT 70 (1), 3" (4), 4" (2).

Looking good! What rocket is that?
The "conduits" running down the side remind me of the Aerobee-Hi in my build pile but I see a little "Ho-Jo" shape on the fins so I know it's neither....maybe???
Do you have a build thread? Things get buried here pretty quick and I have no idea what to look for.

Oh wow!
Not what I was expecting, NICE!!!
I see a written date of 12-02-92 on the box, way before my rocket time!!!
Awesome little sleeper ya got there!!!
Desert Storm Hero!1
I'd like to see it finished and flying!!

SS

Flying is the plan!
(Given the date, it's almost before my time Period)

Glued the canard fins to my 4" LOC Nike Zeus.

Just re-visited your build thread! Looking GREAT!!
Lone Star State!!!
Much more work and detail than than my "disposable-lighter" rockets!!!
Looking good Mugs!!!

One of today's Instructables was a couple who made a Mood Ring Tiolet Seat. So I looked up mood ring paint and ran across this. Imagine a rocket that changes color with temperature.

Mood Rocket!

EDIT: A ring-fin rocket in Mood paint -- MOOD RING ROCKET

I saw that toilet seat!

I'm unsure how the effect on a rocket will be. I imagine it'll match ambient temperature, and Maybe get reddish around the back end for a second

DIY Papered Balsa Centering Rings... I'd rather build than buy, so I'm investigating different ways to make these myself.

See post #76 and #87 here.. . https://www.rocketryforum.com/threads/lakeroadsters-hammerhead-shark.157283/page-3#post-1962806

sitting here with rock sim designing my lvl2 rocket. carbon fiber but heavy. Don't want it to go too high lol. my first high power kit was an apogee zephyr that I modded to dual depoly and called a MkII zephyr, so new one will Be The MkIII (people who know about English cars will get the joke here). still a work in progress going to be at least $1000 worth bigg step up from the apogee @ $90 which I highly recommend as a dmn fine rocket too.

I'm feeling "patriot"ic today as well. Getting work done on the LOC 5.5 Patriot while filming for my video review on the kit.

Depending on how quick the paint would react to changes, the airflow over the wing and the proximity to the motor could show a cool gradiant if you'd notice it in or shortly after flight.

Sean, it would be a neat experiment, eh?

Re-rigged both my Protons with a shorting plug from battery to deployment positive.

Indeed. Are those pigments for use in an airbrush

Yes, that is how they applied them to the toilet seat. Here's the Instructable.

A high power, minimum diameter rocket with an aft facing camera could catch the gradient from motor heat to airflow cooling. Could be cool.

Here's a YouTube video of the application of the Mood Ring paint to a tumbler. I do think that this would be an interesting paint job for a rocket.

Is this to satisfy the new Tripoli rule for a hard switch? If so, that's a nice solution.

Yes. It has side effects I started a new thread to discuss.

And I had built the Protons with header pins to jumper B+ to DP+ to begin with, just in case I ever wanted to fly the two battery option. This is just moving where the jumper is.

Now my Quantums have a soldered jumper. Those will be harder to update.

Just-ish what I was thinking. A high power rocket, not necessarily min diameter, with a rear facing camera. And what it might catch is not only the airflow cooling but also the air friction heating! Make sure that a fin leading edge is in view. If the camera is between fin positions (still up high) and aimed slightly off vertical "rollward", you'd get body tube, fin leading edge, and fin face all in the shot. Correlate with altitude and speed from the altimeter. Then publish.
