Adjustable planing support

I'm adding an adjustable planing support for the kid's workbench that will allow easy edge planing of longer stock. One end of the stock will be held in the vise while the other rests on the adjustable support. It is simply made from the parts shown. 

The two outer cherry parts will be mounted to the sides of the bench and the center part with affixed rest will slide between and lock in position with the plastic knob. 

Make, fix and create. Assist others in learning likewise.
