When I first decided to build this jig I wanted to make sure that I used materials that were going to remain stable. I chose to use some material I had left over from a commercial media cabinet. The core of the material was MDF and it was laminated on both sides with formica. I also wanted to make sure that the guides would not expand and contract in such a way so to cause binding in the adjustable portion of the jig so I used two pieces of precision ground A2. The grooves milled into the upper portion allow for a slip fit with no slop. The grooves for the lower portion are a press fit. One thing I had to overcome was finding material to act as a bushing for the ID of the bearing. What I found was that 1/4” hardened flat washers, which are 1/8” thick, fit perfectly, again slip and no slop. Something I decided to do, that the plans did not call for, was add a micro adjust knob. It’s probably not needed but I’ve found that it helps to obtain a very specific thickness if needed. When I made this jig I did not have the various knobs that the plans called for so I made my own. Call me a yankee but I try to use what I have on hand before I buy something. I’m pleased with how it turned out and how accurately I am able to create thin material. Thanks for looking.
