For hexagonal barrels, diameter is measured from flat to flat side.

When loading the barrel, the weight rating of the tumbler usually means the weight of the barrel and ALL contents should not exceed the rated weight capacity.

 

For effective tumbling, you should aim to fill the barrel approximately 2/3 to 3/4 full.  Therefore you should use about 70% of the total volume to calculate how much media you may need.  The following bulk density data for various media types is a guide only - there may be variation between batches.

    Media Type Bulk Density (kg/L)
    Stainless Steel Shot (mixed) 4.7
    Stainless Steel Pins (1 x 10 mm) 3.8
    Hardwood Cubes 0.45
    Crushed Nut Shell (Standard) 0.68
    Plastic Cones 1.0
    Plastic Pyramids 1.55
    Plastic Pellets 0.55
    Ceramic Balls 4 mm 1.57
    Ceramic Triangles 6 mm 1.46
    Porcelain Balls/Triangles 1.56
    Ceramic Fast Cut 6 mm 1.52
