Topic tags/keywords: jig trick tip

As woodworkers, we are naturally an inventive lot and I think most of us will admit that we are intrigued by shopmade jigs. There is nothing more satisfying than inventing or making a jig that works better and cost less than the store bought variety. However, one of the biggest challenges of making shopmade jigs is accuracy. I’d like to share a few ideas and items I use to make my jigs more versatile and accurate. I would love to hear other’s ideas!

- Paper shims – Each sheet is about 1/100 of an inch thick. Add or take away to adjust your jig.
- Screw adjustment – Turn a knob and you can micro adjust. Nylon set screws are also useful to micro adjusting miter slot runners.
- Tape - Similar to the paper shims, but stays in place for those jigs which require it.
- Hinges – Used in combination with other adjustment methods, I use this on my drill press table where I want to drill angled holes. Combine with a wixey digital angle cube and you have a great way to get accurate angles.

Just a clarification: I don’t know what paper you’re using, but 500 sheets of 20lb bond inkjet paper seems to be about 2 inches thick, so a sheet of that paper works out to closer to 1/250”, or .004”
