Microjig FITFINDER 1/2" Gauge Center Finder & FITFINDER Accessory Upgrade Kit

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.

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.

Set fences for resawing. Set fence positions and resaw material on the bandsaw with zero guesswork.

Center stock on the lathe. Find the center of stock and mount material on the lathe for safer spindle turning.

Set precise cutting depths. Lock in the measurement and transfer to the router or table saw to set cutting depth for flawless lap joints.

Center router bits. Quickly and accurately find the halfway point of material.
