Fyou’ve ever used or seen a router lift, you know that the 3 major flaws with all of them are: 1) backlash,
2) dust build-up on the working parts, and
3) the inability to accurately adjust bit height changes.
Every router lift currently on the market uses either a belt-and-pulley system or some type of chain-and-sprocket arrangement. By design, each of these configurations has an inherent amount of backlash “engineered” into them. Add to that, the fact that all of the working components used to raise or lower the router motor and bit are exposed, thus making them a constant and frustrating maintenance issue of dust and particulate matter build-up. Additionally, adjusting the height of the router bit still requires the use of a ruler or some third party add-on device that fails to accurately or quickly give you the setting that you need...or worse yet, a never ending stream of test cuts.
