How to choose tumbler parts

Match the part to the tumbler model and size before you order. Barrels and liners wear with use, belts stretch and motors eventually fail, so having a spare belt or barrel on hand avoids downtime. Extra barrels also let you run separate grit stages without cross-contamination.
