Introduction: My Ball Mill for Just a Few Quid
I needed a Ball Mill for a Black Powder mix and when i browsed the internet they weren't too expensive but looking at them i thought " I could make one for a lot less".. so here goes.......
MATERIALS...1/ A Float (either for toilet cistern or water tank) 2/ A bolt ( i used an old one i found laying around). 3/ A cork 4/ A wood dowl 5/ 2 drill bits (20mm flat wood and the other just a bit smaller in diameter than the dowl) 6/ some ceramic baking beads.
Step 1: Cut Head
Place the Bolt in a vice or some other clamp and cut off the head with a hacksaw or disc cutter
Step 2: Insert Bolt
Using the vice to hold the cut end of the bolt screw the float on to bolt... This may be a bit tough because my bolt was quite a bit wider but persevere with it.....................
Step 3: Drill Float
Turn the float so the base is facing you and drill a 20mm hole one side and the smaller one across from it...........
Step 4: Insert
Put the dowl in the smaller of the two holes and put the ceramic beads in the larger hole ( i use about 20-30) . Put what ever your milling in and push cork in.............
Put on drill and mill (i use my cordless because its easier to controll the speed).... I have made a few of these for different chemicals... The floats cost me 87pence from Wilkinsons and the Ceramic beads were £3.50 from there aswell......
