I checked the specs from a few manufacturers like flexcoat, CRB, and Pacbay that sell electric turners used to turn blanks when applying finish to thread wraps. Not surprisingly, each offered a different rpm motor. These little AC motors are fixed speed and offered from as slow as 2-3 rpm up to around 50 rpm. One rod builder friend said he used a 10 rpm turner for mixing epoxy, applying finish and drying. Just wondering what rpm or turning speed rod builders prefer when applying finish to thread wraps?
