Big 10inch

Kevin's new 10" Test Tube Rocket. Sports a 5" diameter motor mount and is to be used to test the new 5" motor we are working on. See the Motor Page for more on our ongoing quest for the perfect sugar motor.

The fins are designed to screw on so they can be replaced when damaged. The plywood strips have 10-24 T-Nuts that are taped up ready for foam.


One way to save money on two part foam on a big rocket is to use someone else's foam (thanks Waysie), if you don't want to waste your buddy's foam put scraps in the cavity and pour the two part around it!


The fins test fitted, in flight trim the screws will have washers and the tubes will have T-Nuts and screws top and bottom holding them together. The 10" with the 3" motor tester that it is an upscale of.


The cone is made from an inner structure of 3" plotter tube with a 1.25" dowel to take the landing stress.


A cone of paper is securely taped over structure then it is inverted in a section of body tube and filled with Waysie brand foam.


Fiberglass packing tape makes great handles for test fitting bulkheads. A long screwdriver, a syringe and some tubing make a great glue pump for getting into tight places.


All the parts fitted together for the first time and the rocket prepped, ready to be carried to the pad.


The fin can after it's first flight.
