yeah I will buy some more... What weight would be ideal? can get like 100 1/2 ounce sinkers for $8

[trash can man]

just go for something about the size of a marble

Ive made another small batch... and lit via some fuse. Made a vid but this BP was worse than the first I think. http://www.youtube.com/watch?v=xs-RK54KXrU

3rddegree: I highly recommend finding or building a ball mill. It is a worthwhile investment at least in creating a finer composition.

Yeah thats pretty much the plan. Im getting some more lead sinkers... (50) and I'm trying to sort out a design. If the motor is geared down low enough are the rollers, gears, belts etc required?

Generally 2/3oz sinkers are best. I use 1oz. Half ounce would probably work, maybe if not as well (I doubt much so). 1oz are about the size of a marble (1.5cm approx).
mm I paid €18 for 100 1oz sinkers.
In response to your last post: No they wouldn't be required if its geared down enough. I don't know if you thoroughly understand the concept of gears cogs pulleys etc... But belts are used in the same manner gears are. You'd use belts if you didn't have a gearbox but only had a high-speed motor. Basically circular gearing all depends on diameter ratios. That is to say, if one gear has twice the diameter of the adjacent gear; for every one rotation of the first gear, the second will rotate twice..
However a roller with good grip will be required to set your cylinder to be rotated onto.. This roller obviously needs to be connected to the motor indirectly through the gearing system.
On my ball-mill, at first I had a lousy layer of silicon type sealant smeared around a metal rod for grip. This worked fine until it wore away. I then stuck a layer of grip mat around the metal rod. Doing so made the diameter or the rod much larger. Therefore, the ratio of turning rod (roller) to cylinder was changed from say 1:60 to 2:60 or 1:30 (That is the diameter was increased from say 1cm to 2cm). Since the diameter was doubled, my ball-mill now turns twice as fast! (for every one rotations of the roller, the cylinder turns 1/30^th. You'll also need a strategically placed loose roller on the other side of the container to support it on the turning roller.
Yeah.. Hope that made sense... Sorry if all this was obvious to you. I'll plead guilty to spoon-feeding if accused..

Edit: I'll get you a picture or two of mine if you like. As a matter of fact I need a new container... The edge of the lid protrudes out quite a bit further and thus causes the grip on the roller to wear easily...
