INCRA I-Box Jig for Box Joints (Standard & Shopsmith)

>> Pencil Holder with INCRA IBOX by Garage Woodworks

To get right to the point, the new INCRA I-Box is the most advanced tool ever produced for creating a stunning variety of box joints & finger joints. Its revolutionary design allows faster setup, greater versatility, and improved user safety compared to traditional jigs. At the same time, it's easy to use and the included 1-hour instructional DVD covers everything from basic setup to advanced decorative joinery.

This versatile design works on both table saws and router tables, and it's available to fit either 3/4"x3/8" standard miter slots or Shopsmith machines (use the selector above to choose the version). We also offer unique I-Box Combos and accessories to get you up and running fast - box joint blades, gear for making wooden hinges, spare backer boards and more.
The I-Box is an evolutionary leap
forward from conventional box joint methods - this single jig can be used on both your table saw and your router table, and the IBox's dual pitch lead screw mechanics easily micro-adjust joint tightness & provide a whopping 1/8" - 3/4" range
of pin widths. It's capable of making good fitting box joints using any width cutter within that range into lumber from 1/4" to 1" thick.
The advantages continue far beyond the basics: I-Box-exclusive joints like the Center Keyed Box Joint can be used to produce symmetric patterns on any width lumber, allowing you the flexibility to create joinery that matches existing project plans rather than altering board widths to fit the limited possibilities of traditional box joint jigs.

The Splined Box Joint is yet another INCRA-only decorative joint that's guaranteed to add wow-factor to your projects, and the I-Box can even be used to produce an unlimited variety of classic dentil mouldings!

Nothing says "craftsmanship" like adding solid wood hinges to your projects, and the I-Box can be used in conjunction with the INCRA HingeCrafter to produce wooden hinges in four different barrel diameters and in lengths up to 10".  Works with the metric HingeCrafter, too!

If you've been looking to improve your shop's joinery capabilities with a fast, versatile, and easy to use method for producing box joints of all descriptions, the INCRA I-Box is what you've been waiting for.
