Hey

 

I've been experimenting for quite a while with BP. And finally came across

this formula:

 

 

60% Kno3

20% Sugar

10% Charcoal

10% Sulfur

 

If you have the time and the necessary materials to make it, Please try it and post your thoughts here.

 

(enjoy and be carefull)

 

Thnx

why bother with the sugar? it`s far more effective with the Charcoal alone (no water vapor generated).

I Tried only with Charcoal.

And with sugar it works a bit better than with only charcoal.

 

LP Aspirin

Hmm, working better = different kind of flame? Have you tried concentrating both and seeing which one combusts faster, that's the primary property of BP for me.

I Tried only with Charcoal.

And with sugar it works a bit better than with only charcoal.

you`ve got your BP seriously wrong then, real BP will kick a$$ outa ANY sugar mix you can come up with!

 

btw, are you talking real BP or green meal?

The new one burns off a bit faster than the original one.

The flame is very similar. No big diferences here.

you made some that quick???

As i recall reading from united nuclear

Real BP Would be that meal powder which you grind in a ball mill.

And this green meal would be pre grinding BP Right.

So i think we're talking about Green meal.

you made some that quick???

 

I Have it in stock

 

LP

when I make BP, it takes a day or 2. it sounds like you`ve only got green meal there.

How do you make it. I've tried dozens of diferent formulas.

Maybe it would be better if i did it in a ball mill but i don't have it.

 

On UN they say that

75-15-10 is the most common formula for BP

but then on another site they say 60-20-20

(KNO3-Charcoal-Sulfur)

Which one do you use?

 

LP

75:15:10 (the correct way)

 

I ball mill all the ingredients seperately, then weigh them into their 75:15:10 parts then diaper them all together I add a little water and mix it all together until it`s like bread crumbs, I also add a pich of dextrin (less than a percent) because I don`t have a several ton press!

 

I then wrap this in plastic and put it between 2 steel sheets and press it for several hours, then I take it out and it`s a hard solid block, I let that dry over a gentle heat and it becomes almost like a ceramic.

I then smash the peice up (all wooden tools!!!!) then pass it through meshes to grade it in order of size.

Yeah, milling separately and using wooden tools is probably an intelligent thing to do unless you want to collect pieces of your ball mill or pieces of your hand from the wall.

OK Thnx

btw You any other store than United nuclear which sells Ball mills.

 

LP Aspirin

make your own, it`s alot cheaper

I've been trying to make my own but i just cant find a FUC**** motor to turn my barrel

 

Now i allmost lost all hope.

 

LP Aspirin

buy one of these cheap £4.99 electric screwdrivers then! that`s all I use. and btw, there`s no need to get all hyper about it!

Heh, an electric screwdriver. I never thought of that. But I think I'll still order a ball mill from unitednuclear.com or such (if they even ship them to foreign countries >:/ ). And any way, it's hard for me to make a ball mill of my own because I got no balls.

 

...metal balls, that is. Though I could probably buy them somewhere.

use the unsplit fishing weights then.

 

I use the .45 muzzel loader balls from the gun club, they work just as good

 

rem though, they MUST be lead or the likes, NEVER anything that can make a spark!

Or find some old computer mouse balls they are steel inside, but thay arnt that heavy.

steel`s a BAD no no!, and the rubberised coating won`t do diddly either if left on.

 

ordinary marbles are ok to use, but be carefull of dust or ingestion, glass powder can kill you!

"glass powder can kill you!" Especially if it's from uranium marbles.

 

When it comes to ball mill balls, I think chrome plated steel balls are simply the best. Though if you're grinding corrosive chemicals, chrome's not too good, but if you're planning to eat the stuff you are grinding (spice mix or something), I think chrome-steel is a good if not the best option.

great if it`s not plated. the problem even WITH non sparking balls (tell the jokes later) is that many materials ball milled are pyrophoric when at such a fine mesh and even the charcoal when airfloat is static sensitive. Never ball mill indoors either unless it`s in solution for this reason, it`s also kinder on the ears too

Hmm, now that I think of it, maybe ceramic media like aluminum oxide is the best for not-so-hard materials.

yup, that would be great too, common garden clay is largely Aluminium oxides and silicates

 

personaly, I`ll stick to my .45 shot, it`s only a couple of quid for a 1lb bag.
