John, to get thinner stock through the planner, just add a carrier board. What I do is take a 3/4 piece of plywood, sand and wax one surface, and glue a cross leg to one end. This is like a hook keeping the board from sliding through the planner. Now the planer has a raised table to work from. Thus you can use the planner on thinner stock. It is like adding a carrier board for the CW allowing you to carve thinner stock than the .5 min. thickness.
