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.
Step 1: Parts and Tools list
- 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.
