How to Make a Brass Tumbler

The Process

• 1

  Take a plywood square measuring 6" x 6", which will be enough to accommodate an air condition motor with 4 rods attached to it for mounting purposes. Make four holes anywhere on the exterior of the air condition motor for the rods and make another hole for the shaft.

• 2

  Mark and drill holes on the lower side of a large plastic bowl with a hole in the center of the bowl and at the bottom of the bucket. The center hole that is located on the bowl should be 1/4 inch. Cut the center of the bucket so that the motor will be able to fit into it then make five holes in the plywood square so that it corresponds to the holes on the exterior the air condition motor and the holes on the shaft. Fit the motor to the plywood square.

• 3

  Construct a counter weight and put it above the shaft by taking a steel bar that has a slit at one end and cross drill this bar. Use a set of screws to fully thread the same holes that you made on the shaft in the above first step to the counterweight. Join one threaded rod through the hole that you previously made in the middle of the plastic bowl. Fix the remaining four rods to the plastic bowl. Fasten loosely.

• 4

  Move the four springs and four washers onto the rods and put the rods into the bucket holes. Add a spring, a washer from below, and add another washer to every rod. Make sure that they are fastened with two nuts.

• 5

  Connect a power cord and if needed, put switch functionality to the motor. Fill the material, add brass, close the lid and give it two hours before you test it to see if it works.
