thechewy Posted July 15, 2012 Posted July 15, 2012 ok,well i just took close too 100grams of bp out the rock tumbler. I milled it for a full 24hours. Just tested it out with great results:) maybe 1gram of the powder launched a 8 gram dummy shell into the clouds so high i lost track of it lol. My comp was 64 grams kno 3, 16 grams granulated sugar, and 12 grams charcoal/newspaper ashes lol!! Great for lifting small shells especially if you dont have sulfur
LehighValleyPyro Posted July 15, 2012 Posted July 15, 2012 If you live in the US sometimes you can get sulfur at a drug store. I have before.
FlaMtnBkr Posted July 16, 2012 Posted July 16, 2012 That sounds closer to R Candy with some charcoal added than a sulfur-less BP. Have you checked any gardening stores? They usually have sulfur. There are 2 kinds. You want the dusting sulfur which can run bugs off and I think is used in organic gardening. It can also have up to 10 % of inert filler/ anti-cake. Many people have used it though and some add a little more to make up for the inert portion. The other kind I believe, is a soil acidifier and not what you want. You can also find KNO3. It is used as stump remover (read the label) as well as fertilizer. I buy it in 50 lb bags and it works great. I try to find Haifa greenhouse grade which I think comes from Israel and is also mined in Chile for other brands. Pottery/ ceramic suppliers also carry many of the same chems used in pyro, but can have questionable purity. Just thought I would mention it since you don't have many chemicals.
taiwanluthiers Posted July 16, 2012 Posted July 16, 2012 sulfurless bp is a good prime to isolate chlorate based stars from the sulfur in regular bp...
thechewy Posted July 16, 2012 Author Posted July 16, 2012 thank you everyone! Lol i didnt think anyone would reply. I feel like evryone on this site is pro pyro's i used to make r candy,and made my own red iron oxide cell. But i found a sufurless bp comp on the web and just took from there. All my rockets were sulfurless,and now all my firework type things that actually work....ae sulfurless which os kinda sad
bob Posted July 16, 2012 Posted July 16, 2012 have you tried just leaving out the sulpher? and do some thing like 75:25 I tried some thing like that once it was a diffrent comp it had some thing like 125 parts in it, but it worked pretty good bob
Short5 Posted July 16, 2012 Posted July 16, 2012 Kno3, sugar, and paper ashes? I don't see how that works. The ashes add nothing to the mix being they are ashes and not charcoal and it would seem the sugar and kno3 would burn with a fizz, not a poof.

I burn them unti they are black therefore acts as charcoal. If you burn it to much it will turn white and thats ash. Also if its that wax coated newspapr it whil burn white and not be good

If i do,ill post the results asap. I might beable to use photobucket but idk on my phone its kinda lame
Potassiumchlorate Posted July 17, 2012 Posted July 17, 2012 I think the sulfur belongs there. As I have mentioned in other threads, I have problems with air humidity. The air here is so moist that is has actually made time fuse not to work. But I found that another fuse, that I first deemed inferior due to its plastic being a little loose, worked without problems. Why? I could smell it: it was more sulfur in the BP used in that fuse!
Peret Posted July 18, 2012 Posted July 18, 2012 thank you everyone! Lol i didnt think anyone would reply. I feel like evryone on this site is pro pyro's LOL, professionals, us? Maybe there are a few but this is the Amateur pyro forum after all. Hail and welcome.
thechewy Posted July 18, 2012 Author Posted July 18, 2012 lmao!! Well i ment im most likely the only one having to actually pump stars out of a marker casing! Like everyone but me is up to date and have all the things i wish id have.
dagabu Posted July 18, 2012 Posted July 18, 2012 lmao!! Well i ment im most likely the only one having to actually pump stars out of a marker casing! Like everyone but me is up to date and have all the things i wish id have. You are not alone, I used to use a syringe to pump stars. -dag
bob Posted July 18, 2012 Posted July 18, 2012 You are not alone, I used to use a syringe to pump stars. -dag I still use a syringe I really don't have much boughtin tools I do have a 3 lbs ball mill that I bought and a musket ball mold that I use for making media but that's about it you can make just about any thing you want I know a guy on a diffrent forum that made a pasting machine bob
thechewy Posted July 22, 2012 Author Posted July 22, 2012 lol i have a kids rock tumbler with solid glass marbles as a media,they have weightt to crush the mix with ease. But a few people said use real media,i neve had any problems with it"no cracking or breaking" so ill do with what i have for now:) . Its not to bad though
utmustang07 Posted July 23, 2012 Posted July 23, 2012 Hi new to the site and just looking around. I have used Garden sulfur for years with good results at least in BP. The added advantage is it has small amount a clay which makes a great binder. ok,well i just took close too 100grams of bp out the rock tumbler. I milled it for a full 24hours. Just tested it out with great results:) maybe 1gram of the powder launched a 8 gram dummy shell into the clouds so high i lost track of it lol.

taiwanluthiers Posted July 24, 2012 Posted July 24, 2012 The problem with glass marble is possibility of sparking... which is why it should not be used for bp. It would be good for simply grinding chemicals. Same goes for ceramic media, there are certain ones that are designed to be non sparking but unless you know for sure, don't use it for bp.

Same goes for ceramic media, there are certain ones that are designed to be non sparking but unless you know for sure, don't use it for bp. Could you state the reference for your claim please? I, once upon a time though so as well but I have completely failed to find a single credible source to back it up. In speaking with several others about glass causing sparks, I have found no supporting evidence, no empirical data that shows any sparking from glass on glass impacts. I personally do not suggest glass on any kind as grinding media for lots of reasons, it lacks weight (density) and does erode. I do not like silica in my comps when not intended to be in them. -dag

But a few people said use real media,i neve had any problems with it"no cracking or breaking" so ill do with what i have for now:) . Its not to bad though You say you live in the South, can you find .50 caliber lead balls anywhere? Where I live, we even have dedicated muzzleloader season, so lead balls are easy to find in any gun shop or sporting goods store that sells ammo. I ended up with .44 caliber lead, because it was in stock at the store I went to. I use a 6lb rock tumbler from Harbor Freight for small batches with only one of the jars, and 5 lbs of lead in the jar. I can make 100-125g batches at a time. Perfect for testing new comps.

graumann Posted July 25, 2012 Posted July 25, 2012 Dag, I'll chip in here and pass on something I was told by a chem lecturer a few years ago, no verifiable occurrences but a reasonable statement. The use of glass marbles/beads should be discouraged when crush milling combustible materials as there is the possibility of high iron content in some glasses which can accumulate in the mill. More likely is the glass, again depending on composition, could accumulate a piezoelectric charge.
taiwanluthiers Posted July 25, 2012 Posted July 25, 2012 Lead shots are useful for a lot of things other than guns, the problem being that in Taiwan you can't buy lead balls in any non BB gun (.25, .22, and .177) calibers because all guns except air guns are illegal. Germany is even more strict I believe, anything with a muzzle energy of more than 10 joules are considered firearms and therefore illegal without a license (in Germany one can get such license but you must prove a "need").
Mumbles Posted July 25, 2012 Posted July 25, 2012 Congratulations on adding nothing relevant to the conversation or anything that anyone cares about to the forum.
thechewy Posted July 30, 2012 Author Posted July 30, 2012 well my tumble is very small and uses like 50 marbles,still never had problems with the chipping or anything. When i clean them,they still look a new as the day i got them.i am not very educated on this so forgive me if im wrong.. I use marbles that are made for paying marble. Its for children 8 and up if im correct. But my thing is if they are made for shooting at each other,it would have a hazard warning about sparking.there for i really dont think kids could use sparking marbles for playing. So i dnt see why it would be a problem for just milling bp. well my tumble is very small and uses like 50 marbles,still never had problems with the chipping or anything.
