I have made many, many rockets using the saltpeter/sugar combo.Your post made the hair on the back of my neck stand up. Words like pound, drill, hammer and hot glue on a loaded shell......holy crap. One eyed or four fingered comes to mind for a new nickname. Or worse.Here's a good site to start with if you want to make you own sugar rockets.http://www.nakka-rocketry.netStart with the safety section.
