  I use pure milled sulfur rubber maker sulfur good fast eastern red cedar charcoal and pure kno3 I only sift it to about 50 mesh then mix and mill for 3 to 4 hours in an optimal mill drum no need to mill for half a day unnecessary if done properly. For pyrotechnics purposes I granulate through a 4 mesh screen thats generally the size used in my shells and sift the sizes and I use 1 to 2 percent dextrin or sgrs I prefer sgrs and I use 70 percent alcohol and water to wet in some cases no binder and I use denatured alcohol. And for hot nozzless fuel use camp fuel and 1 percent mineral oil to make fast rockets. Pyro is fun and bp is the most flexible mixtures we use and can make an entire show with only bp

  Did you cook the nitrate in water and mix charcoal in after or just water and alcohol mix?

• 
  @jmohearn2 ай бұрын

  Do not need to cook. Mix all ingredients dry, add 40% H20 of non metal dry ingredient weight (if batch of dry ingredients is 100g, use 40g H2O). Add water in small increments to ensure you dont over saturate (should be clay or play dough consistency), make about a 1/4" pancake and cut into 1/4" cubes. This will make "cut stars" for aerial shells or shooting out of a mortar tube like here. Water works in this mixture because of the dextrin.

  I had trouble with the simmer ring actually working after the stove got too hot before putting it on trying to cook a burger patty in a small cast iron skillet, the flame wanted to come up around the small opening where the two parts slide and from up underneath the rim. but over all it seemed to work before the stove got hot, I'll have to test it some more to see.

•

  I have not used the Maple Polaris but from their website it looks very similar. I’m sure the micro regulator valve their site references is similar to the regulator valve on the Stryker. I picked this one up in a sporting goods store and it has worked out for me. I’d say whatever is in your budget and most accessible will probably do you well getting started. Once you get out on some hikes, learn and experiment with other stoves and cook systems, you will figure out what works best for your needs. I’ve started diving into alcohol and wood stoves but these canister stoves are great to start with and most on the market will work well.

  Very nice and informative video! One question: How can you separate FG from FA, let's say the FG,FFG,FFFG from the 3FA-6FA , since the mess gives equal granulation? 5FA is the same with 3FG, since their grain size is at the 20-50 mess range? After the graphite coating FA changes name to FG? Thanks

• 
  @jmohearn8 ай бұрын

  Yes, the mesh sizes overlap and if the grains are not glazed then they would technically remain as an A class. For home production Its really just about trying to get the grain sizes close to what you want to match with load data for your specific application.

  Sorting helps with consistent results and matching load data for specific calibers. Also helps for different bore sizes to match tolerances from pressure (firearms vs. aerial mortar tubes). If you just want to make something go bang, then sorting probably isn’t as necessary.

  Air float (sublimate) sulphur is not used in industrial production of BP. Its easy to oxidise in contact whit air, since particals are extremly small. SO2 and SO3 corrode equipment and products in which BP is used. Sublimation is process of refining it, remelt and simple crushing, ball miling is recomended.

• 
  @jmohearn10 ай бұрын

  Thanks for your comment! I should have said "very finely ground sulfur" not air float. The description of the product I used states: "It is recovered during gas manufacturing as a molten sulfur. It is then cooled on a stainless steel belt and forms into a flake form. The flakes are then taken off the belt and ground into a fine powder." And yes, ball milling would make it better for black powder.

  Charcoal is what gives BP it's characteristics, far more than the other ingredients. Plum, Silver Maple, Black Willow, Grapevine, Aspen, Alder, Poplar - all are reportedly good choices. I would HIGHLY recommend removing bark though. During the charcoal making process, bark can contribute significantly to the ash content of the charcoal, which would lower the effectiveness of the end product. Bark is like a filter for the wood. It often contains trace amounts of dust, particulate matter, insects/parts, pollution from the air, bird and small animal droppings, (if near a farm) it could contain pesticides or herbicides, etc. Don't know if this is a factual or not, but several books also advise against using straw as a charcoal source, due to it's sensitivity. Rye Straw Charcoal was reportedly used in revolutionary times, and was said to spontaneously ignite just being jostled around in the canvas sacks the soldiers would carry. It was found in modern times that the sand in the charcoal was the primary cause. I personally have not been able to find any source or witness reports for this issue, but better safe than sorry and not use it. For this reason, especially if you live in a coastal region, bark can contain trace amounts of silicate sand (which can turn into micro glass beads during the burning process, and micro shards during the milling process).
