Before reviewing this item I should explain how I came to use it. I was reading a recent special issue of Popular Woodworking Magazine entitled "The Ultimate Guide to Tablesaws 2004". In this magazine I found the article "19 Step Tune-up" by Paul Anthony. This article explained a lot to me and really emphasized the importance of keeping your tablesaw (and other tools) properly adjusted. He explained the many components of a tool that can be checked/calibrated using a dial indicator. I assumed throughout the article that he was probably using some $300 model that would forever be out of my reach. Imagine my surprise when he revealed that he was using the Grizzly dial indicator with magnetic base attachment, and that these items are precise and affordable on every budget!
