Imperial Thickness Gauge for Domino DF 500

The Seneca Woodworking Imperial Thickness Gauge for the Domino DF500 allows you to quickly and effortlessly adjust the Domino fence offset to center your mortise on a variety of imperial material thicknesses. The gauge installs in less than a minute using a Torx T10 bit (not included), and is a direct replacement for the metric thickness gauge included with your Domino DF500. 

The Imperial Thickness Gauge is CNC machined from Delrin material and designed to center on 1/2", 5/8", 3/4", 7/8", 1", and 1-1/8" nominal ply thicknesses (undersized from dimensional lumber)

We currently offer two products to create the correct offset for mortising imperial lumber.   The Domiplate and the Imperial Thickness Gauge.   If you primarily work in only 1/2 and 3/4" material, The Domiplate is probably the right choice because it provides a reliable way to set a specific offset and create many mortises with absolutely no possibility of "Fence drift".       On the other hand, If you frequently use material other than 1/2" and 3/4", the new thickness gauge allows you more versatility in choosing different fence offsets.  However, it doesn't provide that extra "insurance" against fence drift that the Domiplate offers.
