Blackthumb Posted April 23, 2011 Share Posted April 23, 2011 Found one reference to BP w/sawdust in my archives.... I will be posting new trials and improvements in the mis next week. Going to try adding AL and a bit more KNO3...as suggested. Plan on videoing the trials.... Link to comment Share on other sites More sharing options...

Bilbobaker Posted April 24, 2011 Share Posted April 24, 2011 I milled some really fine wood dust into some BP meal yesterday and it showed promising burn times as fine powder.. I'm gonna wet it and make grains out of it for more testing soon.I also spooned a bit it into a short cardboard tube plugged the ends and it made a decent report upon ignition.

dagabu Posted April 25, 2011 Share Posted April 25, 2011 I launched two rockets last night to test a heading and a new motor. I forgot to stick up the Scooter and light it so I will have to try that again tonight. I have a straight BP 3# motor to compare it to as well and will head them with 5g of "F" for end of flight notification as well. Blackthumb, got any video yet?
