I needed to get some resawn parts to a consistent thickness (rails that will be used for a planter and need to be able to accept a bench), and decided to build a fixture that would hold the workpiece, as well as provide fixed height rails for the plane sole to ride on. This is what I ended up with. The rails are simple rectangular stock that I picked up at the local Obi, screwed to an MFC base. They are angled, so that wedges can be used to hold the work in place. Works well enough as long as you don’t fiddle around with the blade protrusion. It accepts parts that are longer than the rails, and can be used for parts that are wider than the plane blade, as the plane is always skewed to ride the rails, you just need a long enough plane.
