What are the alternatives to ramming?
There are two alternatives. One is casting – such as wetting the composition with acetone and pressing it by hand into the tube and letting it dry. This is a pain to do and almost no one does it this way. The more popular alternative is to press it with either an arbor or hydraulic press. For small rockets (5/8″ and below), you can use an arbor press – get a 1 ton model or, if you can find a used one, a 2 ton model. For larger rockets, you will have to go to a shop press – a 10 ton model is best if you are shopping. See presses.html for more about pressing.
