How To Cut Perfectly Sized Dadoes
In this Rockler demo, we’ll show you how to cut dadoes that fit your workpiece perfectly. The Rockler Perfect Fit Dado Jig lets you rout precise dados and grooves at any increment from 1/4'' to 1'' wide. Since it uses a scrap of your actual material for setup, the fit is spot-on, every time. Just rout the first shoulder with the jig in the ''closed'' position, then rout the second shoulder with the jig in the ''open'' position. The result is a tailor-cut dado that fits like no other. Once the jig is set, the stops make it easy to return to the ''open'' position so you can machine as many dados as you like for that thickness. No need to buy undersized plywood bits, or bits for other odd thicknesses—your dados can fit any thickness within the range (19/64'' for example) using standard 1/4'', 3/8'' or 1/2'' straight bits. Not only do you get easy operation and a perfect fit, you also get an integral dust port that lets you hoover up the mess before it ever hits the floor.
