I was work in firework industry at same process you describe.With brass piston and 250t press.After making pucks then you grind pucks as sift it to ff grades

@@accipiternisus649 exactley, it makes sense. Especially for weapons.

This is my bp kzfaq.info/get/bejne/nMt7qsycvcfFgGg.html

Smaller shells use mainly BP for the burst. As the shells get larger I use coated rice hulls for the break. Also a touch of a hot prime to help it ignite.

15mm is a good size.

I've also seen people use sold copper rollers, and also large aluminum brass rollers for 3kg mills

Yes. I bought the 12” square screens from McMaster Carr and used 1x4 boards for the box. I used small flat molding to sandwich the wire to the box. Used panel nails to attach the molding.

Thank you for sharing your thoughts i look forward to seeing more thanks again

No kidding! I wondered about that myself. The first time I made BP I didn't know the differences in charcoal and used an 80 grain instead of airfloat. Not even enough power for lifting! Took me awhile to figure that one out.

I've even tried a formula using nc lacquer as a binder/solvent... It was closer but still not shiny like theirs... My first batch of bp I made, I used charcoal from the store, substituted sugar for a modifier instead of sulfur. It was brick charcoal, so I had to wash the clay and lime out of it before milling it. Worked okay but not as good as Willow, poplar, or hemp charcoal.

Graphite powder.

The shiny coating on commercial bp is graphite.

Kenny that shiny Black powder is commercial sporting powder and it is tumbled to polish it sometimes with graphite to make it poure smoothly and also to make it somewhat moisture proof. There is a big difference between the manufacture of sporting powder and poyro powder for fireworks and this video did not cover that.

I've never heard of using glass marbles for this. If you try it let me know how it does.

@@Tarheel_Pyro There has been rumor that the marble can break down on the edges after awhile and possible create sparks. But I have never heard of anyone ball mill blowing up from it. But, don't go the five and dime way. Go spend your money of some good medium and keep yourself safe.

eastern red cedar and paulownia mixed is suppose to be the best for black powder. I'm really not a purist when it comes to the type as long as it's airfloat.

I have made dummy shells with just sand in them and shot those for testing. Just make sure you have room and a spotter because it’s coming back down. Ned Gorski from fireworking.com launches baseballs and figures the heights.

I buy just the screen from www.mcmaster.com and make them out of 1x4 wood, and small trim pieces on top edges. You can buy already made screens from skylighter.com

You can buy these chemicals with no license. You can buy some BP for use in guns without a license.

Ok cuz I've been watching a lot of vids & would love to try some of the simple builds I'm seeing. Thinking of getting the turbo pyro kit from skylighter to try some stuff out. I saw ur vid on supplies & tools used is there anything else u recommend getting to help me out. I don't want to have to throw a ton of money out if I don't have to especially being a total novice. There might be things I'm seeing used that I simply just don't need for now. Thanks for getting back to me I appreciate the help.

Country Boom always use potassium nitrate, it won't work with perchlorate and it's also cheaper. And yes perchlorate can be used instead of chlorate in stars and is safer than chlorate but still take care.

Awesome! From wich country you are? Here I can't find any Perchlorate.... And I really want to use it for new products.

@@pyroxtremevuurwerkpro4537 im from the united states. Where are you from? I can get the perchlorate in any quantity and reasonably priced too. Isially amywhere from 5 to 10 US dollars per pound of fine, milled, high purity perchlorate.

@@countryboompyro6746 Awesome! Well I am from The Netherlands and here it's quite hard to get... But, If I want KNO3 I can buy as much I want... Last time I bought 150 KG of Potasium Nitrate for smoke projects

@@pyroxtremevuurwerkpro4537 awesome. I love making smoke stuff. Well if you want amy perchlorate let me know and maybe we can figure something out. Would probablly be expensive for me to ship it to you tho. If you look on youtube there are ways of making it from bleach by using electolysis.

it acts in 2 parts, fast drying to reduce kno3 crystallization and a wetting agent

Have you tried purifying your sulphur? A friend of mine is in the process of purifying his. The store bought garden sulphur he bought is 92% or 94% pure, it is slightly off color, not the vibrant yellow it should be. It's really quite a simple process. Since sulphur is insoluble in water, you can purify it with simple water, to eliminate any other contaminants from entering your product, you can use distilled water, but a few extra tap water minerals won't effect anything. The way my friend does it is in a few steps. 1st. Put sulphur into a container which will allow you to add about a litre of water, with enough room left over to shake the contents. 2nd. Add hot water, hotter the better, but not too hot where it can burn yourself, or damage the container. Shake contents fairly vigorously, making sure that the water is thoroughly mixing with all of the sulphur. Shake for a few minutes and allow the contents to stand for 10 to 15 minutes. After contents have stood, all of the sulphur will resettle to the bottom of the container, slowly pour off the water being careful not to lose product in the process. 3rd. Repeat. You can repeat this as many times as you like. 4 or 5 times is about how many my friend does it. 4th. This time repeat the same process with cold water. As some contaminants will be soluble in hot water, others may be soluble in cold. 5th. After you have completed all the steps, and you have been careful not to lose product. Slowly cut the top portion of the container off. If you are using a 2 litre pop bottle or juice bottle. Drain off any remaining water, then pour contents into an aluminum foil lined baking tray or similar. Spread contents out and allow to dry for a couple of days. Finally, you will notice that your dark yellow, gross looking sulphur, is now a vibrant, bright and beautiful yellow. And damn near 100% pure. I wouldn't say it's exactly 100%. But it is pretty darn close. Anyway, that's the only, and simplest way I know how to purify your sulphur. Play safe.

I would definitely purify if you are planning on using it in your muzzle loader. Extra unknown contaminants might not be too good for your barrel.

@@Subway1427 Thank you. I do plan shooting it. First thing I'll do is a burn speed test.

@@Subway1427 Thanks very much for the information. After trying in vain to find sulfur in pellet form I bought it finely powdered. I can get 100% pure sulfur, but only in 50# bags. I didn't realize the procedure for purifying the fine powder was basically the same as for pelletized, so your information is very helpful. I'll do the purifying procedure as you suggest. I haven't yet corned any BP, but I'll make it that way. I'll do the first corning using door / window screen. I want to end up with FFFg or FFg. I can shoot both. I have rifle and revolver. All I've done so far is to make some charcoal using chunks of yellow pine lumber. I'll make small batches of B.P using various local woods to watch the burn test, then make bigger batches with the wood that works best for gunpowder. Thanks again for sharing the information.

Don't bother puryfing it. It is the charcoal that makes the difference. www.creagan.net/fireworks/blackpowder2.html#AGC pyrobin.com/files/Black%20Powder2.pdf

McMaster Carr has lots of options.

Good question. Never got an answer on that myself.

Yes, that shouldn’t be a problem. Actually you’ll have a head start.

I think the addition of a small amount of graphite gives it that totally black and shiny look. The graphite supposedly keeps it from clumping and provides a small amount of moisture resistance. At least that's what I've read. I'm trying to figure out exactly how it's done so it doesn't slow the burn rate.

@@sempertard I would think if it were tumbled in a ball mill without media that it would work...

@@houseoffire72 I like that idea. That would work.

@@sempertard I really think it would. I would also think a little would go a very long ways since its tumbling...

If you make your powder using the 75 15 10 composition formula and granulate it, it should lift shells no problem. If you’re not using air float charcoal and mill your comp it will not be powerful enough. The first time I made BP I used the wrong charcoal and had that same issue.

Yes, thank you

There are lots of binders that people use, and some have luck not using any at all. I'm working on testing the use of phenolic resin as a binder, such as red gum is sometimes used. Both make harder granules but are expensive to use. Dextrin works just fine, rice starch is also sometimes used. Just depends what's at hand and what works for you. As for my exparementing in phenolic as a binder, I happened to buy a good quantity for cheap, I aready use it in my firework stars, and I can use acetone to bind it. Drying time is hours, and I dont worry about re-crystallization of the kno3. Through the small tests I've conducted my normal dextrin bound milled powder performs similarly to my unmilled phenolic bound.

Anything over 100 mesh is considered airfloat. Usually when you purchase Charcoal that says to Airfloat it will at least 100 mesh or better in the lot.

you used a hair dryer when working with BP? Are u insane, before you try something you better read more about it.

@@pyrofox1461 - Who used a hair dryer? Where exactly did you read that? Whoosh, right over your head, LOL.

@@6977warrior1 so what electronic thing did you use?

@@pyrofox1461 -It says it right in my original comment - Did you even read it? It was meant to be funny. The story was fake and funny. Whoosh, right over your head, LOL.

It is actuali screening but you need to have drop 40 cm in can so its AIR mixed
