Star Mine Problem.


Recommended Posts

Posted (edited)
Hi i made a star mine but the paper plug just turn to one side and dosent pop out. the stars fly out but only 50cm. Is this because of the plug is not tight enough or to slow bp ?. Or not enough black powder ? Edited by Sondre

Sounds like slow or not enough BP.

Tested it it was quite slow after granulated it. i probably added little to mutch dextrin.

Are you milling or screen mixing BP? Also try omitting the dextrin altogether and just using 70/30 isopropyl alcohol to granulate the powder. The grains will be a little softer than dextrin bound but you'll get an improvement in your burn. If you decide to stick with dextrin cut it back to around 2%. You'll still get hard grains but without so much reduction in power. Weigh everything accurately!!!!
