superspike23 Posted July 25, 2012 Share Posted July 25, 2012 (edited) hi I tested with only a 2 star StarMine. it sounds bad but I'm happy because both stars have burned in the air. I'm just disappointed in the poor quality of the blue stars. here the video: link-->http://www.youtube.com/watch?v=r22ZL_ivVa8&feature=youtu.be Edited July 25, 2012 by superspike23 Link to comment Share on other sites More sharing options...
psyco_1322 Posted July 26, 2012 Share Posted July 26, 2012 Maybe you should try that at night, when you can actually see the color. What was the formula? Link to comment Share on other sites More sharing options...
superspike23 Posted July 26, 2012 Author Share Posted July 26, 2012 Maybe you should try that at night, when you can actually see the color. What was the formula?the composition is: Hardt Blue Star # 2 potassium chlorate 65 Copper oxychloride 16 lactose 10 PVC 5 dextrin 4 Add 25% alcohol / 75% water Tonight, three failed stramines 1,5g granulate bp for lift http://youtu.be/iWeUDp8Igjg Link to comment Share on other sites More sharing options...

Mumbles Posted July 28, 2012 Share Posted July 28, 2012 Have you considered trying a larger star mine containing more than 2 stars? In my thinking on this, unless there stars are well fitting, there will be a lot of potential for blow by of the lift gases. Are you still using the same batch of BP that you posted a video of in the comet bomb problem? If so, the slow lift you showed there will still be slow lift in star mines. That will have to be corrected if you want to ever get appropriate heights. Link to comment Share on other sites More sharing options...
superspike23 Posted July 28, 2012 Author Share Posted July 28, 2012 (edited) I will try more size soon. Here are the currently used size: http://img11.hostingpics.net/pics/348531001.jpg I use the black powder that I granulated with 5% dextrin. For these small starmines I take 1.8 grams.

Col Posted July 29, 2012 Share Posted July 29, 2012 You could try adding a small wad of kraft above the stars to contain the lift gasses a little longer. Link to comment Share on other sites More sharing options...

dan999ification Posted August 23, 2012 Share Posted August 23, 2012 indeed, for small stars that are not suited to the bore i make a cup from a circle of card formed over a dowel with a few holes, like a sabot, it will prevent blow by and maximise height, you can also use less lift with this setup, half a gram should lift a 15mm bombette 40-50ft with lifting aid/ disc to prevent blow by.
