kpknd Posted January 11, 2014 Share Posted January 11, 2014 I did a number of experiments with sugar and BP fuels by simply mixing and screening. For some reason the hand mixed fuel blows the motors that would normaly work fine with fuel that has been milled 1 to 3 hours. I would expect the hand mixed fuels to burn much slower than milled fuels. What's the deal? I was using the 1/4" ID motors. Link to comment Share on other sites More sharing options...
ddewees Posted January 11, 2014 Share Posted January 11, 2014 Usually lack of compression, or crack are the main reasons for Cato. Link to comment Share on other sites More sharing options...
leedrill Posted January 11, 2014 Share Posted January 11, 2014 I have come to believe that the anti cake on my kno3 is what use to cause this I no longer use hand mixed fuels I see it this way. If I put my granular kno3 in a container it maintains flow and does not cake if I put air float kno3 I have milled in a container with basically no moisture some of it ends up as hard as a pressed grain Link to comment Share on other sites More sharing options...
