Chuck Gripping Depth
When turning a large pieces such as a bowl, for safety reasons, allow a minimum amount of wood for the
chuck to grab while turning.
1. Cavity base (inside grip) – for a 2" diameter base, minimum hole depth is 3/16".
2. Spigot base (outside grip) – for a 2" diameter base, minimum grip is 3/16".
Lathe Speeds
Turning: 500-1500rpm
Sanding & Polishing: 1500-2500rpm
Make sure your wood is properly aligned and balanced when mounted or re-mounted. Use slower speeds for
larger work.
Maintenance
Brushing is all that is needed to clean your chuck. If the chuck becomes sticky, soak in varsol or mineral spirits
with 10% oil added. Soak for thirty minutes and blow dry.
