An illustration of the Lyman method of moly coating.
Lyman have a published guide https://www.lymanproducts.com/media/user/file/7/6/7631343_7631343_7631384_super_molly_finishing_kits.pdf .
This is the same method, but using alternative components.
1. case media tumbler
2. ceramic media
3. case tumbling media
6. steel insert for tumbler
7. acetone draining jug
The Lyman guide linked to above, contains the intructions on how to use everything, so read that first. The pictures that follow are to illustrate the point, and show the same result without the Lyman Moly kit, basically using what you have with what could be more readily available.
First prize is to get the Lyman Kit, personally I've never seen one in South Africa.
