Fjp92 Frequent Poster	posted December 13, 1999 12:07 PM Can you please tell me if it would work if i take a brazz tube (1cm in dia. )and fill it with molten lead and then when cooled take it and cut it to 1 inch pices. Will this work for milling media for a bal mill
Ho ju Moderator	posted December 13, 1999 05:50 PM fjp are you over 18? if so you can just go by round lead .50 cal balls used for muzzle loaders. (can you use steel or do you NEED lead) cause i am sure you can find steel ball bearings somwhere ------------------ -Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

Blaze Frequent Poster	posted December 13, 1999 08:52 PM filling the pipe should work.. as long as the lead doesnt come away from the inner pipe creating a gap, which could result in the accidental mixing of chems. Im pretty sure you can buy lead balls without a shooters licence, cost too much but.
Fjp92 Frequent Poster	posted December 13, 1999 11:21 PM Thanks for the advice all of you. I think im gonna trie to fill the pipe couse it is damm hard to find balls for muzzle louders in south africa and i all ready have a shit loud of lead that i can work with.
darcey Frequent Poster	posted December 13, 1999 11:22 PM why don't you just buy some large round fishing sinkers? Thats what i use in my mill and they work fine. They are made from lead and can be bought in heaps of different sizes.
Fjp92 Frequent Poster	posted December 17, 1999 04:38 AM Can one use gypsum so make a mold for lead or will the lead be to hot on it or maybe get stuck on it? It woulg be realy easy to make a round mold from gypsumn.
VeHeMT Frequent Poster	posted December 17, 1999 06:34 PM Do you mean some kind of plaster? It should work. I remember there being avery good post on rec.pyrotechnics about molding your own lead cylinders. Something along the lines of wrapping aluminum foil(lead will most likely stick to it, paper wouldnt hurt to try) around a wooden dowel 1.5-3cm in diameter and then burying this dowel in sand or soil then sliding the dowel out of the hole. And then just poor your molten lead into the hole.
Fjp92 Frequent Poster	posted December 21, 1999 07:09 AM Ok now i have Finiched my ball mill but i still have a few questions. The mill is 11.5cm in diameter and a little less than 20cm long. I have filled it about one third with lead balls (3cm in diameter) Will this give good results or can i do sonmething to improve the mill? When i mill say blackpowder for how long sould i be milling it or does that depend on the mill? By the way plaster of paris worked fine to make a mold. I sinply mixed some in a bucket and when it was dry i took a drill head (ones used for grinding, it hat a round ball on the end) and drilled half way in to to pices of the plaster and placed them on top of one another.
nbk2000 Moderator	posted December 21, 1999 08:33 AM From what I've seen on other sites, the longer you mill, the better the BP. The minimum seems to be 4 hours with 12 being the most. I'd say mill it for 12. Of course your ball mill is somewhere where if it blows up (always possible with BP) it won't kill you? Or draw the neighbors attention. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
Fjp92 Frequent Poster	posted January 11, 2000 12:05 AM Can lead be used to mill AN?? Can Aleminium(spelling sorry) be ball milled, what media is to be used if i want to mill some?? Thanks
nbk2000 Moderator	posted January 11, 2000 03:46 AM I don't know if aluminum can be ball milled. I assume your thinking about making aluminum powder in your mill, right? Al powder is made commercially by blasting a high pressure air stream through a stream of liquid aluminum. The molten droplets are then collected in water to solidify. So maybe you could use an air nozzle to blast a stream of aluminum you've melted into a kiddie pool of water or a bucket or something. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
