Shaping Metal with a Planer : Part 3

Using my "Antique" 1943 Metal Planer to make a precision 4 foot long straight edge.. In part 1 and 2 I take you through the setup and planning of the second and third edge of a Richard King 48" cast iron straight edge.IN part 3 I show you how I stress relieve the cast iron edge and set it up for final planning. This restored planer lives in my home metal shop ( well it is a BIG home Shop :) ) . It is a great machine and is the last of the planers as they stopped making them a long time ago..
