Over the weekend I started two new Micro Odd-rocs. One a full size 3/8-16" x 6" Machine Cap Screw, the other a fully threaded 3/8-16" x 6" stud. both with Hex nuts and Fender washers Drag fin.
First thing I had to do was determain if I'd be able to find a material to produce or hold the Threads needed.
a short piece of 3/8 thin wall Polycarbonate tubing proved to fill the bill perfectly.
Hex Nuts and Hex Head will all be made with 22lb High density foam.
1-1/2" diameter Fender Washers will be either .063" Polycarbonate or paper laminated Basswood. We'll see what the mass of each end up.
The Cap Screw body and stuffer tube/motor mount will be standard T2+ & T3 (.375") craft tubing. I rolled a custom computer paper stuffer for the Polycarbonate stud do aid adhearing the motor stop/shockline mount and to help with the heat.
both have 3/8-16" x 1.0" Threaded Polycarbonate "Nosecones" with T2 Full length shoulders. this give me plenty of area for any noseweight that might be needed tho I do not believe any will be required.
.052" holes in the Nuts and washers will serve as Launch lugs.
The plan is to prime and paint both with Testors ModelMaster Stainless steel, buffed than future coated. Hope to get a few more of the pics out of the camera soon. Both models are almost ready for primers.
