Good info, thank you. I'm short on mgal, I have to make it by hand. I have
plenty of aluminium powder tho. 200# I believe, would that work?

Hello
I have been making sugar motors for the last 15 years and I also wanted to
try something new this year
I am currently trying AP with silicone ( the neutral type). I did try
Richard Nakka’s one with addition of ammonium chloride to control the burn
rate and it extinguish itself when in a casing. When I burned it outside a
casing it would leave lot’s of hash.
Then I tried another mixture with 15% of magnialium . At first it worked
pretty well, I did 3 tests without a problem see video.

But then I let the grains dry longer , retried it and I managed to break 3
casings
The mixture that I did burn really well it hardly left any hash but I
think that it would be a better candidate for an end burner when fully dry
65% AP, 22% silicone and 13% magnalium
I found it very hydroscopic
I would also appreciate help
Boris

hi, ill soon have a fair amount of AP made via electrolysis of sodium
chloride and would really like to have a fuel that I can make without the
specialist resins like HTPB. Does anyone have a recipe for a polyester
resin or another EASILY ACCESSIBLE resin? I'd ask about epoxy but it seems
that there is so much variance with epoxies between brands that finding one
like yours may take a lot of resin buying to figure out. worth trying tho.
any other AP recipes would be appreciated, I am currently experimenting
with silicone sealant but the amount of stiff ash it produces has me
worried.
Many thanks,
Nikolai Nielsen
