Automatic Measurements

Find 1/2 thickness of material in seconds.

The FITFINDER 1/2 Gauge allows you to find the 1/2 thickness of any material up to 3" thick. Create perfectly fitting joints with zero guesswork, set fences and transfer cutting depths instantly—all with no math or measuring.

Henry Wang, Microjig Founder

The FITFINDER was conceived while founder and inventor, Henry Wang, was developing the Dado Stop. While the Dado Stop solved the problem of cutting the width of a dado, setting the dado’s depth for half-laps still proved challenging. Henry realized that the solution was already there—from a Greek mathematician that lived over 2 millenia ago—Pythagoras. He applied this simple principle of geometry to a common woodworking process, and the FITFINDER was born.

FITFINDER 1/2 Gauge

No math or measuring required.

The FITFINDER 1/2 Gauge automatically finds the center of your workpiece using simple geometry. Lock the measurement in place and set the cutting depth of your saw blade/router bit, or set fences.

  1. Match the material's thickness - Place material under P2, then lower P2 so that it rests on top of the material.
  2. Find the 1/2 point - The bottom of P3 automatically adjusts to exactly 1/2 the thickness of the material.
  3. Transfer measurement - Lock in the measurement and use the FITFINDER to set cutting depths and fences.

Got questions?

Does the FitFinder Work with any other Lock Miter Bit?

Our Lock Miter Bit works with our FitFinder because we have a shelf milled into the bit to set the height from.

No other Lock Miter Bit has this feature, so they do not work as well with our FitFinder 1/2 Gauge.

WOW What a joy

We used the Fit Finder with the Lock Joint Router Bit. Works perfectly. On our last build we used a different bit with a setup block that took forever to setup and then it wasn't perfect. What a POS. The Micro Jig setup took only a few minutes and the fit is GREAT. The engineering is fantastic and allows a woodworker with low vision the get good results. THANK YOU.

It all started in a garage workshop...

Henry was working on an intricate project and was challenged with cutting thin strips on a table saw. His frustration with traditional methods sparked one of the most innovative woodworking tools to come out in decades.

After countless hours and prototypes, the Grr-ripper was born. Henry has continued to innovate, and Microjig now offers multiple unique product lines all over the world.
