'I battle gravity'
Made a fin guide for my Wildman Jart.
Tomorrow I will cut out the waste material and it will be fully functional.

The lake is currently frozen. It’s a perfect launch “field.”
Here I am hiking out to the launch site across the ice with a backpack full of rockets.

iirc at one time the controllers were in the box set as a kit, during the 80's my Power Pulse launch controller was a bag of parts with instructions and it used the flat Polaroid Camera battery.

Yes, the Electron beam controller use to come unassembled in the 80's and early 90's. I still have mine from '89, had to build it and apply decals to it. Those were the days .
Have you got (access to) a drill press? that makes the motor mount hole easy, and the antenna holes, well, easyish.
Thanks for the info guys. This must have been between my teenage rocket lust and my 1st BAR incarnation.

Sitting at a Drs appointment and my UPS delivery alert goes off. My order from Apogee Components is sitting at my door.
The Zephyr has landed!!! Lol

To center drill a sphere clamp 2 1" boards to your drill press. Using a 2" hole saw drill thru the top board. Set the sphere in the 2" hole and it is centered to drill what ever size hole you need.
You could screw the 2 boards together and keep it around for the next time. Use the small center drill hole to line it up.
For Styrofoam it would be a good idea to take it off the drill press and break the sharp corner of the 2" hole with a router.

Finished building a relay launch controller.
I built a little circuit board with transistors for continuity testing and to control a 30 amp SPDT automotive relay.
Wired it up with 22mm industrial pushbutton and selector switch that I had laying around from another project.
I used XLR3 plugs and connectors simply because I have hundreds of feet of microphone cords from a theater that went out of business.
Continuity test current is around 10ma. Bench tested Estes Igniters and Chinese Ematches for full 60 seconds just to confirm no fire.
Now I just have to untangle some 100' cords that look like spagetti and get some 16awg zip cord and alligator clips for the igniter leads.
I really wish somebody would market a printed circuit board that just needed the components soldered on (anybody at Eggtimer listening?)
Hoping to do a launch test on Saturday.

Discovered I never cleaned out my six grain Pro 24. Something tells me this was a Moon burner

I’m in the groove tonight As I mentioned earlier my package arrived today. Eager to leave Dr apt that seemed like a lifetime 45 minutes, lol a 30 minute drive I finally was able to lay my hands on the box from Apogee Components..i was not surprised to find the quality and the shipping as others have stated it to be. I’m stoked and can’t wait to get to building this kit. 2020 will be the year to remember in Rocketry for me...
No need to use two boards; clamp on a 2× or thicker and drill partway through it. Also, you can brake the edges of the hole with a rasp and/or sand paper without risking the alignment.
The antenna holes are trickier, since they are not radial (i.e. not pointed at the center of the sphere.) What I'm thinking of is:
- Move the block with the hole sideways.
- Put a pole of some sort (like a long piece of your motor mount tube) in the motor mount hole.
- Use the pole to indicate and the angle for the antenna hole.
Yes I do. I also think I have a neat solution to the antenna mount.

As an RC pilot I will be affected, as a rocketeer? Maybe. It's all about a airspace control. With UAVs being suggested as delivery use the FAA doesn't want to miss out on the possibility of revenue. As we all like to develop things I would speculate the FAA would want to review the rules governing model rocketry also.

For your need, just go to Harbor freight and get one of their cheap drill presses, I got the second cheapest one. It's not bad considering the source, not a production machine but has a 1/2" chuck. The cheapest one does not, don't get it... About the cost of a couple high power flights...$139

I lucked out. A friend gave me a Shopsmith Mark 5.
Seven months later I have received no answer After letting this slip my mind and thence through the cracks, I have sent another email repeating the offer. If I still don't get an answer I'll try another nearby school district.
I was on Google Earth today looking for the latitude, latitude, and altitude of the Tripoli launch area at the Richard Bong State Recreational Area in southeast Wisconsin, getting ready for launch late April. I noticed that there was some smoke & smoke shadow and that there were cars and what looked like the launch controller setup. I checked it in Google Maps & it was the same. I emailed a friend of mine who lives in that area & launches there and sent him the Map link. He looked into it and it was taken during their launch last July. What are the odds, eh?

'I battle gravity'
Last night: Put in my order for a 3” Cherokee upscale that I hope to pick up this Saturday if we don’t get rained out.
Today: Finished up my fin guide for the original Wildman Jart I bought years ago. Modifications thus far are opened up back of nosecone for ballast, bulkhead, and eyebolt; Estes threaded motor retention; and kevlar y-harness and shock cord (close to delay grain).
It should fly really well on F67W and F50T...obviously a small field Class 1 rocket appropriate for the SARG Gibson Ranch launches.
It will of course have a metallic black fin can and fluoro pink body and nose cone. My flying colors for ease of finding.

Finished painting UCANDOIT2
It's a very basic 3" 3fin and nosecone design
My 10 year old nephew designed the paint scheme, not really what I would have picked out but he loves it so I couldn't resist.
He got an Apogee Apprentice for his design work.
My 21 year old son picked out the Rustoleum Sparkle paint and ordered it from Amazon. It runs like water, really need 85 degrees or more to make it work well. He doesn't work as cheap, he'll probably want an "L" motor for his troubles.
Just needs a coat of clearcoat, rail buttons and motor retainer installed.
Will probably fly it at SEVRA launch in a couple of weeks.
Just spent the past six hours or so doing a design review (schematic and PCB) for the electronics payload for the university team I am mentoring.
Thanks for posting this. I built the Magnum in the late 80s and lost it on its first launch. I couldn't remember what it was called. Now that I know what it was maybe I'll do a scratch build replica.

It’s a great kit! I just finished assembling mine a few weeks ago.
wsume99, I combined all the tiffs from kuririn's link into a PDF. Here it is.
