This instructable is for a box joint jig, which is necessary for this particular carpentry technique. I made it at TechShop in Menlo Park (http://techshop.ws). I needed this tool so I could create a box joint (also sometimes called a finger joint) using the dado stack bit on the sawstop table saw.
A jig is needed to easily cut 1/2" "fingers" and equally sized spaces in the end of a board. Using this tool will make those cuts clean and efficient.
The box joint is an alternative to the more popular dovetail joint. An interesting point that the box joint is stronger than the dovetail joint, and does not require the custom dovetail jig. Instead, you can create this one with scraps and belt out box joints all day long. Strength test was done at http://woodgears.ca/dovetail/index.html.

To create this instructable, you'll need the following parts:
- Wood scraps - ideally some 1x12 and 2x4 scraps - length will depend on your table saw, but two feet long should be plenty.
- Wood screws - 1 1/4" (at least 14)
- Wood glue
You will also need the following tools (all of which are available at Tech Shop!):
- Table saw with standard blade and dado stack bit set
- Mitre saw
- Power sander
- Power drill
- 1/8" wood drill bit
- Phillips or flat head bit, as required for your wood screws
- Carpenter's combination square

If you're building a jig, it's assumed that you already familiar with the above tools and parts. That said, this is an instructable, so I'll go into some detail as necessary. Please comment your corrections.

Thanks a bunch for sharing.
It's simplicity and almost foolproof idea ("almost" as fools can be very creative) makes it one of the best idea (maybe the best) I've found on the net for a box joint jig (and there are a lot of them ! â¦Â ).
However as a foreigner I have trouble to know what exactly is a"dado stack bit set" as stated on the list of required material.
â¦Â
Is it the two blades contraption that is shown on your table saw ?â¦
If not how this two blade system is called, and is it something "homemade" (if so how did you make it ?) or is it available on the market (a link would be absolutely fantastic) ,â¦
Thank you again.
I should try to put two or more equal cutting blades in my hand grinder, for make these unions in my homemade cutting table.
