What did you do rocket wise today?

[ecargmij]

Worked on repairing the goblin.. got her all cleaned up.. a body tube and coupler should be here early next week.. you can see the ejection charge went off right when the nosecone and tube were compressed up againstthe rear of the motor.. there's a pattern on one side of the cone from the charge where it took off paint..

Examined the path before me.

Deployed a large (3'x4') cutting mat to my workbench. Can't wait to actually do something with it. Originally getting a small mat (12"x18") was the second stupidest thing I did when getting back into rocketry; the stupidest was to actually live with it for 9 years before realizing that I could get a bigger one. ¯\_(ツ)_/¯

I couldn't get enough open space on my small workbench for the 12" x 18" one.

I got the first coat of Rustoleum primer on four of the Rockies i've been working on and this will be the very last time that I use a Rustoleum product

Mine won't be as open as it is in the picture all the time...

Still trying to get better at papering. Papered some fins on the New Way Little John that I've had sitting around half-finished for months (lots of irl stuff happened to slow me down).

First round of paint for my youngest's Big Bertha. She is obsessed with fire type Pokemon so this one is getting yellow and orange for Flareon.
Then treated myself to the 29/180 and 29/360 motor casing combo pack at Wildman...

Finished up the rebuild of my crashed PML Andromeda converting it to dual deploy. This is a test of the charges and the Fluctus flight computer.

Dave's not here, man.

Since my first name is Dave. At that time and still I have heard that a lot.

There was no wind this morning and I decided to fly something. But ended up not.

Tried spraying fluorescent yellow on top of metallic silver. Result meh.

Through no fault of my own, I'm fairly sure I can still name all of the original Pokemon. The kids had the cards, the games, the little figures, I think I picked up a lot of it through osmosis. I coached a 3rd & 4th grade basketball team and one kid announced that he would no longer respond to his name, but only to Mew. And he would only communicate through mews. I still occasionally find the Burger King stuff in various boxes.

If it makes you feel better, I spent 30 dollars on a GBA in order to play Pokémon emerald…

Ps those games are addicting…

 

[Blast it Tom!]

And designed to be that way, much like casinos. Be careful. Computers are wonderful tools, but like anything can also be used for very destructive purposes. </dad mode off>

There is a actual casino in them so it makes sense

I want a 12⨯18 or 15⨯24 matt that's reversible, but with the usual inch grid on one side and a centimeter grid on the other.

Get the largest size you can and trim down if necessary.

Went to Lowes for an eye bolt for the Guideline rocket. and installed it on the 3" bulkhead

 

[cwbullet]

I thought about rocketry

 

[krislhull]

came home from work, and packed my car for a bright and early departure in the morning to the sod farm.... Looking forward to what will hopefully be another great day of flying

Applied some Elmer's Carpenter Wood Filler on the Anduril Roadrunner.

BOSS decals, part 2.

Just the big one on the disc fin left.

 

[Gastrok]

I'm working through the finishing steps on an Aerotech HV Arcas, and I've got the launch lugs attached as described in the instructions. The kit also came with a set of conformal rail guides which I also want to install, but there are no instructions for installation. Obviously they should be centered between 2 fins, one near the bottom of the airframe and the other somewhere a little above the fins, like regular rail buttons.

Question 1: Should I use CA glue to install the conformal rail guides or should I use epoxy to attach them to the airframe?

Question 2: Is there any structural downside to not installing the fin can? It's just a cut up piece of tube glued between the fins, but maybe it secure the upper section of the fins which are not in contact with the airframe?

Thanks!

Built a launch rail for my EZ-DD using a 2m length of 20mm rail, a cheap speaker stand and some scraps lying about the garage.

Great idea - I have a similar speaker stand kicking around.

I can't take credit for the idea, I've seen several of them on this forum that I took inspiration from.

Did some research last night on Australian hardwood densities for the Level 3 build project, then visited a local woodworking specialist, Carbatec, only 2km away from home and bought a 1m plank of 106mm x 30mm Spotted Gum for A$22. Cut it into four and the plan is to glue me a block of approx. 106mm x 120mm x 250mm for turning down at a later date to make a hardwood nosecone tip for the flax level 3 project - Flax Capacitor.

My measured density of this Spotted Gum is 1071 kg/m3 ( approx. 66lbs/cu.ft. ) so the finished tip ought to weigh approx. 420gms to assist with stability, but in a green/sustainable way instead of the more traditional aluminium tip. Well, that's the plan for now.

Also chased the supplier in South Australia for my replenishment of Bio-Epoxy, and it should be here on Tuesday, including an extra 1.5kg for the delay. Bonus!

To paraphrase Lisa Simpson, "I know all those words, but I can't make sense of that paragraph."

That’s dense wood! If you have extra and some lathe time, you can make wood rail buttons too.
