Simple, easy-to-use dowelling jig for edge joining stock


Rockler Dowel Drilling Jigs

Dowelling is a time honored, and very efficient method of joinery. If you do a lot of dowelling, then it makes sense to purchase a versatile, precision jig that enables you to make a wide range of dowel joints.
However, if you are looking for a simple, easy-to-use dowelling jig to edge join stock, then you'll want to have a look at the Rockler Dowel Drilling Jigs. Simplicity is the keyword here - you can use these jigs with a minimal amount of layout work. It's practically 'clamp and drill'.

The registration line make layout a breeze  
There are three jigs for making dowel holes of three sizes - 1/4", 3/8" and 1/2". You use the 1/4" jig for 1/2" stock, the 3/8" jig for 3/4" stock and the 1/2" jig for 1" or thicker stock.
All have a 3/16" replaceable transparent acrylic face. Three black lines are scored onto the face of each jig - one line marks the center of the acrylic face (which will be the center of your dowel joint), and the other two mark the center of the drill holes.
The only drawback with acrylic is that it's likely to chip or break if dropped onto a hard surface. Rockler doesn't sell replacement faces, but you can easily make one. You can get acrylic from sign shops and some building supply centres.

Align stock, draw a registration line, clamp the Rockler jig in place, and then drill away          

The 1/4" and 3/8" jigs will enable you to drill holes that are 3/4" apart on-center, while the 1/2" jigs drills holes 1" apart on center.
To use these jigs you simply align the boards you want to join together, and then mark a registration line on each board. Clamp the jig to a board so that the registration line on the jig matches the registration line n the board, and drill away.
I found that two clamps are necessary, or else the jig has a tendency to shift sideways. If you want to daisy-chain dowel holes simple insert a dowel into the second hole, reposition the jig, and then drill a third hole. A bit time consuming, but it gets the job done.

Ideal for quickly making face frames 
If you use the jigs for making face frames, the narrowest boards you can use with the 1/4" and 3/8" jigs will be 1-3/8 wide; for the 1/2" jig the narrowest board will be 1-3/4". You can draw registration lines on your stock, or use the outside edge of the frame as a guide. Either way works fine.

You can't use the jigs to drill on the face of stock
Because of the design of the jigs you can't use them to drill on the face of stock - there's no way to clamp the jig to the stock.

Quick, easy, precise  
These Rockler Dowel Jigs represent excellent value for the occasional user, enabling you to drill edge-to-edge dowel holes quickly and accurately.
