Please note, that the design used for this project is the BSD Rocketry - Horizon. Instead of doing it the easy way, and buy their upscale version. I decided to build everything from scratch...

[To technical section with parts, and checklis]

Level 3... In progress...

Done - So here it is... the final result.
A 6" rocket... Together with its smaller 4" cousin. I was pleased with the result.
Now it's left to determine how well it flies.


 

It always starts with a plan though... Mine was to do a larger version of my Cert 1 rocket, the BSD- Horizon.
The initial idea was to do it something like the picture below is showing. The basic design is still valid, with some reallocated space for the electronics bay, and shifting the main, and pilot shute around.
So I am aiming for dual deployment for my certification flight.


 

Here's my L1 Horizon - 4" in comparsion to the 6" one in progress. Put together with some tape, and good hope...

1. Playing with epoxy...
Yes... Well, I am in the game... still... With some lag time to compensate for.
See... This is me doing some serious sanding on the %¤#%¤# body.
It takes some serious sanding to even out the darned fiberglass - even with
some primitive vacuum bagging... except without the vacuum.



2. All parts are epoxied though...
And that always looks neat, and easy, when others are doing it. But gets into
being rather pesky, when you do it yourself. However... The result is a
revard in itself. And yes, I would do it again...
So far, I have just about used up 4liters of epiglass two component epoxy on this project.


The inside was reinforced with epoxy and fiberglass. The space between the upper centering ring, and the bottom one, were filled with expanding foam - to fixate the fins.

First picture below, is the parashute compartment that went into the nosecone being reinforced with fiberglass. The second picture below to the right show the reinforcements to ensure that the parashute will not rip out the inside of the rocket during deployment.

The fins are made of epoxied and carbon reinforced 1/2" (12mm) plywood. I am confident, that whatever the final outcome of my certification flight... They will be parts surviving, even a hard landing.



3. And the parts...
Well... The parts laid out on our front yard. This is still without the motor mount
assembled. The 360cm shute (main) and 100cm (pilot) is out..

Shutes (Red Baron), couplers, motor tubes and deployment bags are purchased from Rebelrocketry in the Netherlands! The Nosecone is from Roffes in Sweden, and the rest of the stuff is from various sources in the known world...



4. Coming together...
Slowly, but with some confidence, I am starting to smell the morning air... It still is NOT finished... I have some serious building left on the electronics bay, and the motor mount is not finished.
I also need to have a dialogue with my TAPs, Rolf Örell, Sweden and Frank De Brouwer, The Netherlands about the construction etc.


But it will all come together... eventually ;-)





Disclaimer... No animals were hurt during this page construction... Although payload, our chiuaua (resting in my supervisor - Myran's- confident hands), is wondering why I am custom making him a carbon fiber helmet, and trying the parashutes on him for size...
