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 Bundle

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.
FITFINDER 1/2 Gauge Bundle

Consistently well-fitted lock miter joints quickly and easily.

The lock miter joint can’t be beat for making columns, newels, posts and cabinet scribes, but the bit and stock have to be exactly centered together. Only the Microjig Lock Miter Bit features a Center Finding Platform in the bit body to set the correct bit height the first time.

Once the height is correct, only the fence needs to be adjusted to perfect the fit. Greatly simplify router table setup for perfect joints with minimal test cuts and wasted stock.

Router Tables

The Grr-ripper provides incredible command over your workpiece on the router table. Whether you’re using the fence or freehand routing, its powerful grip controls stock and protects your hands from dangerous spinning bits.

FITFINDER 1/2 Gauge Bundle

Table Saws

The Grr-ripper was built for the table saw. It acts as a moving blade guard, shielding your hands from the saw blade through the entire cut. Right out of the box, the Grr-ripper can cut stock down to ¼” x ¼”. Because it provides three directions of control, your cuts will be cleaner and more precise.

FITFINDER 1/2 Gauge Bundle

Jointers

The Grr-ripper’s proprietary Green Grr-rip material provides all the traction you need to properly flatten stock on the jointer. Because of its powerful grip, you can feed material over the cutter head without having to apply too much downward pressure.  The Grr-ripper makes proper face-jointing technique easy and safe.

FITFINDER 1/2 Gauge Bundle

Band Saws

The Grr-ripper's legs and main body maintain a constant 90-degree angle. It can be used on its side, which is ideal for resawing on band saws. The Grr-ripper glides along the table top and applies even pressure against the fence with your hands clear of the blade. Even pressure means less blade drift, resulting in smoother cuts.

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.
