Then screw on the lid and plug it in.

A word of warning: This is about the loudest noise you will ever hear from a tumbler.

Since there is no polishing media in the tumbler, the bullets are just bouncing on the bottom of the container and it makes a lot of noise.

I start it up and go in the house for about an hour or two.

The bullets bounce around in the moly and it impregnates the surface of the bullets.

When you open the tumbler, the bullets will look like this.

I built a box to use to separate the bullets from the excess moly.

It consists of a box to catch the excess powder, and an upper box with a 1/4 inch screen to allow the excess powder to fall through, leaving the bullets on the screen.

I then pour the contents of the tumbler onto the screen....
