Mini Whistle Rockets DVD / La Duke volume 32

MINI WHISTLE ROCKETS - by Steve La Duke. In this 78-minute fascinating seminar, Steve explains why it is so important to use a sleeve when pressing rockets. And he explains in great detail why determining pressing force is so necessary to keep the rocket from blowing up. He even details how much comp. to press with each increment! And he gives a formula for determining pressing force! He says not to use a nozzle for whistle rockets and explains why. Then he wraps it up with a careful, detailed demonstration of how to make the comp. This is critical when working with whistle comp. and you don't want to miss a single step in his process. This alone is worth the cost of the DVD.
