I stumbled upon this old thread while Googling for David G. Sleeter, author of these works. I purchased copies of "Building Your Own Rocket Motors" (1983) and "Amateur Rocket Motor Construction" (2004), both by Teleflite Corporation. I also have downloaded copies of the "Five Cent Sugar Rocket" and the "Homemade Hydrogen Report" by the elusive Mr. Sleeter. A search of Amazon and other rare book sites indicate I made a good investment.

I also obtained a copy of a sugar rocket construction manual entitled "Bravo Niner" by John Drayna, which appears to have been based upon Sleeter's work. http://www.privatedata.com/byb/rock...oberscience.pdf Drayna had apparently applied for a patent on a device he called "HANEES" for "Heat Activated Non-Explosive Ejection System". Very interesting stuff.
