1. Simple & Cheap Router Dado Jig Tutorial

Simple & Cheap Router Dado Jig Tutorial

This is a very simple dado jig that you can easily make whenever you need to make dados. All you need is a piece of plywood and 2 pieces of solid wood.

In this tutorial, the plywood used was a 1/4-inch thick, while the first piece of solid wood used as the fence is about 3/4-inch thick. The second piece of solid wood used as a T-square is 1/2-inch thick and 3/4-inch wide.

The plywood has to be initially wider than the dado spacing because you'll have to route it down to size. It should also be longer by a 1/2-inch at least.

There are descriptions and pictures in this tutorial which show you every step of the process in detail. You'll need some glue, a brad nailer, a square, and clamps to get this project done.

Exact-Width Adjustable Router Dado Jig Plans

Unlike the previous adjustable dado jig, this one has fewer parts, but you'll need to make rabbets along the guiding rails.

It features a 1/4-inch slot which is 2 inches long and allows you to adjust its width to make dados up to 2 inches wide. You insert your shelf material, position the rail, and then tighten it using a wing nut and carriage bolt.

This jig also includes rabbets on the sides of the rails. These allow you to use a wider guide bushing than the bit on your router, and this makes your routing faster and better, especially on wider dados.
