Dear User,

Make sure that you know what you are doing before attempting to manufacture 
your own rocket engines. Even the smallest ones can be dangerous.

Here's a list of links to model engine manufacture at home - more can be 
found using www.google.com with appropriate keywords.

Please make sure that you work under adult supervision and that you do not 
break any laws pertinent to manufacture of high-energy substances in your 
country.
