This is a simple router planning jig I built today. I have a stack of oak and poplar 4×4’s that a friend of mine and I will be turning into a workbench top for him. Though I have a 6 inch jointer, most of the 4×4’s have a bit of twist and cupping to them. I tried truing one up on the jointer and it was taking forever.
Now that I have a proper workbench I thought it would be much easier to take the twists out of these boards my keeping them stationary in reference to a flat surface. The router is stationary in the jig though I have it drilled for the router to be in 2 separate positions. Most jigs the router slides back and forth inside the jig. I just slide the entire assembly around. It has oak runners on the bottom that are chamfered so they slide nicely. The sides slide up and down on hardboard guides and are tightened to the main assembly with t-slot bolts. The knobs are inside the jig.
The last picture shows my benchdogs from hell. I made them specifically for this project they are roughly 3” square by 2-1/2” high with 3/4 oak dowel epoxied into the body. Used in conjunction with the wagon vise on my bench they do a great job of holding the 4×4’s.
Using a 1” dia straight bit I true one edge then I rotate the board 90 degrees and make sure that the newly flattened edge is perpendicular to the benchtop. Then when I true the next edge I have 2 square sides. The planer does the rest.
