I ordered a 4" fiberglass Nose Cone from the Rocketry Warehouse to scratch together a mid to high power upscale of an Estes Fat Boy. Thanks go to Dave "Green Jello" for telling me that Rocketry Warehouse has 4" Nose Cones. Scaling up from the original 2.6" diameter to 4" diameter meant a scale factor of 1.54X.
I purchased a length of 4" Body Tube, two Centering Rings, a 29 mm Motor Tube and an Estes 29 mm Retainer from my local hobby shop, and a U bolt and 1/8" plywood from a hardware store. I cut the Body Tube to 12.31" long and cut some slits for Through-the-Wall Fins.
Below are pictures of the slotted Body Tube, assembled Motor Mount, and Fins....
