Comp. screening in the remainder of charcoal afterwards. this gives a figure 5: arbor press used to compress comp. into the powder is to work it in a little by hand and then pound it pumping crossettes: the crossettes used in this 6 shell are made using the 1-1/4 nituff coated crossette pump made by rich wolter. note that.
at some point fairly early in every pyro career we realize we need to be able to make good black powder (bp) from scratch. bp is used in aerial fireworks shells as lift and burst powder. add the dextrin with the black powder comp and then ball mill as usual. potassium nitrate says: january 4, 2011 at 1:53 am.
use 75/15/10 willow based bp or similar that has been ball milled in a pyro ball mill for at least 3.5 hours. mix +3% mineral oil with lacquer thinner (about 1 part mineral oil to about 10 parts lacquer thinner) and then mix that with the bp and dry for 24 hours.

If it is at all greasy feeling or mushy, there is way too much water. save some dry mix on the side just in case it becomes too wet during the dampening. granulate the damp comp by rubbing the packed ball over a 20 mesh screen. do not use any screens larger than 20 mesh. if the screen plugs, the comp is too damp. add more dry comp and thoughly .
