Star looked nice. Should look good flying through the air.I think we're in the wrong topic area...I've never used lampblack, just substituted airfloat,formulas work but don't know how much difference the lampblack would make. If you are only looking for smaller amounts (like ounces) you should be able to find redgum on ebay,look for yacca resin.Thanks for the tip, gonna need to get some Lampblack and red gum also. Anyway my own recipe Bp star which was pumped and cut. The vid is about a 1/4"x1/4" pellet.

My question here is how to attach a rising comet on top of a snug fitting cylinder shell that is bottom fired. Is it possible? Maybe sticky match from lift charge to comet? I have added small comets to 1" shells and they work well, but would the same work on a 3" shell?

The lift gasses take care of this - no need to match the comet at all (presuming it's primed sufficiently!), whether it's on the top or bottom. Just make sure it's securely attached.

I use 15g of 3FA Equiv for 2.5" shells. 2FA I would use 20g. 2Fg is finer and faster so 10g might be about right. KP needs to be well confined to work. I would use BP first to burst and use fibreglass strapping tape to get as good a break as you can then try KP with strapping tape to see what difference there is

Ok thanks, that seems to be general area I was thinking of. The O.D. of the casing is 1.75 inches which is a little smaller than yours, so I may try a smaller lift charge like 5-8 grams. I'll try it out on a shell loaded with dog food pellets and see how long it stays up.
What kind of altitude should I be looking for in terms of burst height for this size of shell?
