SLIPFEATHER JIG

For any box makers viewing this website, I've included my adjustable Slipfeather Jig. I've seen a lot of different designs for a slipfeather jig and mine may seem a little extravagant but I figured I'm only going to build one of these and use it for a lot of boxes so I might as well make it easy to use and quick to set up.

 

BASE

The base is made from birch plywood and pine. The pine is ripped at a 45-degree angle to support the plywood bed of the jig and is glued and nailed to the bottom plywood as shown. 

Also attached to the plywood bottom piece, are the two 3/8-inch by 3/4-inch miter-slot strips.  It is important that these strips be precisely installed so that there is no side-to-side motion and that they are installed at exactly a 90-degree angle to the front and back of the jig.  The jig should slide freely in the miter-slots with no slop.

Bed

I've routed and chiseled a dado to one of the sides of the bed to accommodate a short section of T-channel.  This is used to install the slide for adjusting the distance between the slipfeather slot and the end of the box.  The photos below show the T-channel installed in the dado and the slide installed (with a knob and bolt) in the T-channel.

Slide

The slide is simply two pieces of plywood glued and nailed at a 90-degree angle to slide on the bed of the slipfeather jig base.  One end of the slide has another piece of plywood attached as the stop-plate.  A hole is drilled in the appropriate location over the T-channel for the lock-down bolt and knob to be installed.
