What did you do rocket wise today?

If it's a small model-sized one, get posterboard. You can practice/change tips, and best, draw on it and follow lines.
I'll put it on what did you do not rocketwise today.
Sanded the seams on the plastic nose cone
spent 3.5 hours on OR drawing up a 1/4 scale Sea Killer which would have a 3-in booster section and a 2-in top section and I would use Dollar Tree plywood for the fins and get some standard cardboard tubing so it would be super cheap and single deployment. Using "H" motors.
Looking forward to the video there!

Yesterday, a gallon fo U.S. Composites thin epoxy with their medium hardener arrived. Time to glass the airframe for the Estes PSII Nike Smoke and finish glassing the fins for the FiberSwarm. (I bought the pumps, so it should be easier to dispense than my Aeropoxy. Though, I realize that Aeropoxy uses a 3:1 ratio by volume, so I might be able to get some pumps for that, later.)
The Nike Smoke airframe glassing will get white pigment added to the epoxy. We'll see how that works.

OTOH, a van de Graaff or Wimshurst machine could be relevant when painting. You put one charge on the spray gun and the opposite charge on the object you're painting. A trick I saw in a factory once, though they weren't getting the charges from anything so steampunk as either of those gadgets.
Spent 2 hours on open rocket program.
More hand painting on BOSS. Decals hopefully soon.

Searched, and failed to find an open rocket file for the standard BMS school rocket (not the 3" one) so used photos on the net to guess at bodytube and fin dimensions and some of the internal components mass. Sim showed about 1cal stable and to a little over 200m on an Estes B6-4 or Quest B4-4 which passed the sniff test. Will update with actual dimensions/weights and publish when my kits arrive.

Still trying to resist using evil CA instead of wholesome, high inducing nitrocellulose based glue and lacquer. Adding carbon reinforcements to Jetex rocket glider. Probably should have used thicker, light wood instead. It's not meant to be pretty, though. Wing is based on this model of a Convair F-102, but leaving out the fuselage, putting motor on top, and using two fins. Plus somewhat enlarged. I call it a rocket glider, but it's a slow rocket and will launch horizontally. Or, at least, that's the plan.

scale it so the main tube is 0.976" and it's 14" long
Ignore that. Not close.
Try this.
And I've uploaded it to Rocket Reviews

Found out how to do rail buttons on OR.
Been falling down a certain rabbit hole for a few months now: a metal/silver paint that handles fingerprints, accepts colour, accepts decals and clear coat without mottling.
This may be it. Plastic scale modellers are raving about Tamiya’s AS-12 bare metal finish. I have watched a ridiculous number of YouTube videos about… yes… a can of spray paint.
Anyhoo… scored a few cans from what seems to be a meagre supply here in Oz. Just need some good weather and an appropriate
rocket. I’m thinking a V2.
It’s $12.40 a can here, and Tamiya’s little cans only go so far.

I had a look at your ORK and while there are a lot of similarities, your PVC nose cone is MUCH heavier than any of the BMS cones in the Open Rocket Library which has a big impact on the stability. Here's mine for comparison (sorry about the dark background, I normally do this in the evening and try to avoid too much white light).
The clue was in the file name. Estimated from a photo.....and Estes standard tube info.

What kind of grass are you going to smoke on Sunday?
I have several school rockets. I give them away to kids that are interested. If you want them I'll get them for you.

I sent the Traveling Rocket to the next person in line.

That would be great, thanks. It's mainly the fin dimensions that are just guess work, but if it was easy to weigh the dowl and nose cone hook I wouldn't say no.
I'd love to be in a position to give them out, unfortunately with the current exchange rates and shipping around the world the best I can manage is selling at cost.
Dowel weighs 1.05 grams. nose cone hook weighs .88 grams. Need anything else please let me know.

Dave's not here, man.
That's a really nice finish. Hopefully the weather will be good for the May launch at Grove City!

Add: Doesn't interfere with radio transmissions...
Too expensive here as well: https://www.hobbylinc.com/tamiya-as...lver-3-oz-hobby-and-model-lacquer-paint-86512
That's $12.95 in your dollars, according to Google today.
