Bolster_Plate.pdf This is a scan of the new bolster plate for my Famco 3R. The diameter is 8"D X 1" thick, as cast. It appears to be cast iron with a turned top surface, painted edge & bottom. There's a 1.5"D x 0.19" deep recess centered on the underside, with a 3/8" roll pin for a pivot. Pete Keillor
