1/4 Scale Pershing II Project

I originally concieved this project as an L3 project. But I discovered it would be on the light side for an M at Geneseo. So we will see.

I will document this buid project kind of blog style. Also I will keep track of costs to see how the cost of a project like this can be executed at.

I like to build from scratch. The specs and strategy for this build are:

- 8” Main airframe diameter using glassed Quiktube.
- Transitions and nosecone assembly to be made from hotwired form and glass like the Honest John project nosecone.
- 3” main motor mount with 2 54mm for optional cluster flights.


	Nosecone - The nosecone in this project is going to be the most work. After that, the rest of the project is easy. Below is the Rocksim snap shot of the nosecone assembly design.


	The nosecone is made of of three transitions and a shoulder. Between each transition will be a 1/4 plywood plate to help define the transition changes when hot wire cutting the foam.


	A central tube forms a core of the nose cone assembly. Access to the core will be provided at the base of the shoulder in order to insert noseweight and/or elecronic tracking devices.


	Starting the Nosecone Here is picture of the nosecone base. The short length of Quictube will be the shoulder of the nosecone. Two 1/2” plywood centering rings support the central tube. This central tube will be the core support for the foam blocks from which the nosecone shape will be cut. The shoulder is covered with 10oz glass. I used a sleeve. After using sleeves I now know that life is too short to be wrapping glass around tubes. Sleeves are the way to go. Below is a picture of the glassed tube. Cost: Quiktube section $2, plywood $1, centertube free, glass sleeve and resin $2 = $5 so far.
