braddsn Posted November 14, 2014 Share Posted November 14, 2014 As per a previous post of mine, I was having some lift issues. Thanks to the advice here it is solved, as you will see in this video. I was previously using 2FA in a cup taped to bottom of shell, and using 10% of shell weight. When I switched to 20% of shell weight, I didn't see much improvement. So I granulated some 4FA, and confined it to the bottom of the shell instead of loose in a cup. Fired this shell tonight using only 10% of shell weight. I was amazed. The lift was twice as effective as before. I don't know whether it was the granulation, or the confinement, but WOW what a difference. The stars used in this video are left over dud stars that I basically just needed to burn instead of throwing away. They are not great. They are TT to blue and it was a batch that I messed up. I have since perfected those stars. My next barrage of shells that I will shoot next week will have all new and hopefully perfected stars. Ok so here is the video. Oh and I think my white flitter rising comet is improving. Link to comment Share on other sites More sharing options...

enanthate Posted November 15, 2014 Share Posted November 15, 2014 Nice shell! some white in there too?For what it's worth, I use lift loose in a cup, works fine. About 1,5mms granules (3fa?) Link to comment Share on other sites More sharing options...

psyco_1322 Posted November 15, 2014 Share Posted November 15, 2014 I'd guess the improvement was mainly from the granulation. In the small quantity you are using and speed of the powder, I wouldn't think the confinement wouldn't make much difference. Link to comment Share on other sites More sharing options...
braddsn Posted November 16, 2014 Author Share Posted November 16, 2014 Psyco I would bet you are right. The granulation certainly makes a difference when I burn small piles on the ground to test it. But I went ahead and confined it too, not really much out of the way to do so. I read in several places that the granule size makes a difference.. but in my head I did not believe it was going to be the answer.. but it was! Learn something every day! Thanks for the compliment SideGlance, it is a 4" shell, white flitter rising comet. Link to comment Share on other sites More sharing options...
