An Idea for an Adjustable Skew Plate

To make the skew adjustable, we would have to open up the opening in the MDF backplate slightly to allow one roller to be adjustable left and right as well as up and down.

A second piece of MDF would be used to hold the adjustable parts in position and let it serve the function the one piece is now doing.

The adjustable parts would have to have two halves in order to capture an adjustment screw in between them. The idea being you put the screw in place and then glue the two halves together and the screw then cannot be removed but it can supply pressure left and right on a nut which pushes and pulls the back roller in and out in relation to the fixed roller which can only move up and down.

You still have to use bolts like you have now to lock it down once adjusted, but it would make it easier to make fine adjustments a quarter turn at a time by loosening just one bolt.

The idea being that you use the bottom adjuster to get the height of the two rollers even and then that plate serves as a resting block for the moveable piece which adjusts the in and out which corrects for the skew.
