Please read all the way through the instructions before building to be sure you are capable of finishing it.
This instructable was based on pictures from United Nuclear check it out http://www.unitednuclear.com/ballmill.htm
The finished product should look similar to this
Step 1: Materials Needed
1. A motor -- I got one from a old dryer that is rated for around 1600 rpm which is good for this
2. 2"x4" -- Amount will vary with the size of the mill.
3. Pulleys(4) and Belts(2) -- Size will also vary. I was able to salvage mine from a old washer.
4. Ball Bearings(4) -- You may be able to get some from old junk or buy the cheaply.
5. Switch(1) -- Get a standard light switch.
6. Wire nuts and electrical tape -- Hardware store.
7. A rotatable wheel (optional but recommended) -- Like on the bottom of filing cabinets.
8. A container -- Size will vary.
9. Two poles -- For shafts make sure to get them to fit inside of your ball bearings.
It may seem like a daunting list of items but they are fairly inexpensive and you can salvage most of them or you may even have them laying around your house.
Step 2: Obtain the Motor
You should be able to find how to get it out by yourself but i will do my best to talk you through it.
1.) Turn the machine over and locate the screws on the bottom. (may be on side or back for different
2.) Take the screws out and unbolt the motor from the bottom panel and remove the panel.
3.) When the motor is loose follow all the wires to the motor and pull any plugs on the motor to be
able to remove the motor
4.) With the motor removed find the power cord going to the machine and cut it off (you will need this
Step 3: Prepare the Base
1.) Use (will you be using it for small batches of chemicals or large batches.)
2.) Area available (where will you be storing and using it)
3.) Cost (Cost will vary with the size..generally the bigger the machine, the more it costs.)
For this application I will be making the dimensions 2 ft wide by 1.5 ft long.
1.) cut two pieces 2 ft long and two pieces 1' 2" long.
2.) cut a piece 5 in long and another 7 inches long
3.) screw them together using the guide shown
Step 4: Mount the Motor
For my motor I need another way of mounting because my mounting plate is not accessible. I will use metal straps to tension the motor down. Mount it in the shaded area shown in the picture.
Depending on your motor, the pulley system will vary so use what is already there if possible.
Step 5: Add the Shafts and Bearings
After the bearings are mounted, insert your shafts through the bearings so they extend out as shown in the second picture. be sure that when you pully is mounted on the shaft closest to the motor that it will line up or the belt other wise may slip.
Step 6: Add the Pullies to the Shafts
Step 7: Add the Wiring
Step 8: Get a Grip!
Step 9: Add the Angler
this doesnt need much explanation just hold the front up (front being the way the motor is pointing) and measure 30 degrees and screw a leg on both sides.
the angle is shown in the picture courtesy of united nuclear
Step 10: Optional Step
Step 11: Done!
Note: do not use more weight than the motor can handle and be safe using this following all guide lines and percautions found here http://www.skylighter.com/fireworks/how-to/use-a-ball-mill.asp
