Essential router-table jigs: Veneer trimmerSee how a pair of crowned boards makes a jig that lets you joint perfect edges on a stack of veneers
This jig consists of two identical poplar boards bolted at their ends. They hold as thick a sandwich of veneer as you need, so you can edge-joint them quickly and perfectly. To keep the clamping pressure uniform, the boards are purposely crowned. First, make multiple passes over the jointer, shorter each time, to create steps in the board. Next, run the board through a planer, step-side down, to put a gentle curve on one face. Finally, run the board through the planer step-side up and plane off the steps.
