A pair of adjustable jigs for accurately setting up your planer blades within their block. With a lockable vernier setting and magnetic feet, all the blades in the cutting block can be set accurately to the same height. This is most important to give a clean finish to your work. The feet are magnetic and swivel to accommodate different diameters of cutter blocks, whilst the knife itself is held in place by another magnet. The beauty of these jigs is that the blade is held by the magnets allowing you to set the height and secure the blade in one operation. Then you can repeat the process for each blade, keeping the same setting each time. If you are using these jigs on a surface planer or planer/thicknesser, you can set the blades to the outfeed table and keep the jig settings for accurate repeat settings each time the blades are sharpened or replaced. Please note, these are made by the original design manufacturer and so are the best quality vernier setting jigs available.
