Delay grain part 2

[Crimson0087]

What chemicals do you guys use to make abdelay grain. I've tried the epoxy/knsu and it doesn't light. I know they say it will light ynder pressure but if the motor only Burns for 1 second d and I need a 10 seconds delay how do I keep it lit for the other 9?

I make my delay by adding sodium bicarbonate to my knsu... I had to experiment to get the percentage right and it wasn't what I read about. Start at around +2-3% and go up from there.
