ROBUST STEADY RESTS are used to support large diameter bowls and hollow vessels when working on the interior. They are also used to support long spindles. Long hollow forms especially need the support of a quality steady rest. They are manufactured to fit four sizes of lathes: 16″, 20″, 24″ and 25″. All are constructed from a rolled ring made from 1.5″ diameter 11 gauge steel tubing. The wheels are heavy duty & industrial quality, not roller skate wheels. Steady rests are made to order. You need to specify which lathe you have when ordering so that we can install the correct tenon to fit your ways.
