After a bunch of fun-time with SolidWorks, the preliminary payload design is complete. This 1 foot long section of fiberglass coupler is going to house all of our cameras, scientific instruments, and telemetry hardware, so we've made sure that it will be spacious and strong. The electronics will reside on double-decker sled made out of G10 sheet, and will be easily removable. It will be held in by two opposite aluminum endcaps threaded for 1/4-20 eyebolts. The eyebolts will be attached to shock cords leading to the booster and the upper body of the rocket. Stainless-steel 8-32 threaded rods will run the length of the payload, holding it all together. Hopefully the payload will not turn out too heavy once we actually construct it...
On the to-do list are finding out where in the outer phenolic section of the payload can the photodiodes and cameras be mounted. Having the electronics in hand will make that easier.
Enough talk, here is a picture of the assembly:
