Joel Corwith

Joel sent in several retainer tests and shock cord. Much of the shock cord had the knots in them.

Nick Stich

Nick sent in the first fin can with a very detailed data sheet. He through in some swivels and quick links for the hardware testing, and some small Kevlar for the shock cord testing.

Robert DeHate

Robert sent in some mailing tube. Some plain and some glassed. The glasses tubes consisted of a polyester resin sample and a West System sample.

Bill Kennedy

Bill sent in the wood dowels. These are for friction fit tape motor retention testing. These things are furniture quality. We are using these instead of motors because if the testing machine takes on a life of its own, (and it has) we wont destroy a good motor. Beautiful job, Bill.

John Coker

John sent in our first fin material test pieces. There was two materials: G-10 and aircraft plywood. He also threw in some Kevlar and nylon shock cord. This is a very scientific effort. He sent in a comprehensive data sheet with loads of information. Very impressive, John. http://www.jcrocket.com/adhesives.shtml

Rick Dickinson

Rick sent the largest contribution in length of shock cord. He sent about 75 feet of 5/8" tubular nylon. This was used to do several tests such as stitching and knots. Thanks, Rick, for the contribution. 

Ken Alger

Ken sent in a big assortment of shock cords to test. These were particular interesting because there was a mix the type you get from the hardware or sporting goods store and "rocket stuff". He also sent in a tube he gets from blueprint paper. This was a very heavy walled tube and the results were impressive. Thanks, Ken.

Jerry Irvine

The biggest contributor so far has been Jerry Irvine of US Rockets. He sent in a box of tubes, couplers, fins, RC's and MMT's so big they brought it to the lab with a fork truck. There was thirty five 3" tubes alone. Jerry really gave the project a huge jump start. He also sent in additional 30 tubes for a glassing test and all of the materials for all of the fin can tests.

James Padfield has done some testing as well. His site tests some composite materials used in fin construction. Excellent data.
