SETUP FOR DADO WIDTH

 

Clamp, or bolt, the Front & Back Fences of the Dado 

Jig to the workbench. Always check that the Front Fence is 

square to the Stationary Track before beginning.

  

Select the setup workpiece you want to cut the dado for. 

Loosen the Adjustable Track and place the setup 

workpiece on edge vertically between the sized 

1/4” MDF Fences. Position the Adjustable 

Track so the workpiece is sandwiched 

snugly between the sized 1/4” MDF 

Fences, tighten the two knobs 

on the Adjustable Fence and 

remove the setup workpiece.

Workpiece sets dado 

width by indexing 

between 1/4” Fences

Butt the two Work Stops against the back edge of 

the workpiece to be dadoed and tighten the knobs. 

These hold the workpiece against the Edge Fence.

Clamp the workpiece to the workbench, or clamp 

stops to the workbench on either side of the 

workpiece, to hold it’s position while dadoing.
