Sherline Steady Rest Riser Block- The steady rest (P/N 1074) can be used with the riser blocks in place by using the steady rest riser block to raise it to the same height as the headstock and tailstock. An example of where it might be used would be in turning a large diameter part that has a long shaft that needs to be steadied to keep it from wobbling. 1290 Sherline Steady Rest Riser Block Instructions
