Make box joints without a router table or a table taw!
This is my box joint machine. If you’ve ever had to cut box joints in excessively tall stock, this contraption is for you.
It translates a horizontal push to a vertical router cut. Now you can cut precise box joints with your stock laying flat.
The tool is constructed of two parts: a parallelogram router guide, and a base.
I built this prototype out of MDF. It’s configured to make 1/4” thick box joints in up to 3/4” thickness stock. A 1/4” dowel at the front placed exactly 1/4” away from the router bit serves as a relative spacer between cuts.
Actions speak louder than words, so let’s jump ahead and see this in action!
And there’s the box joint.
If you’re interested to see this machine as it develops, follow along and you’ll get the updates. I have plans to make it a lot more customizable in the future. Thanks for reading, and good luck with your box joints.

Neat design. I have a use for it but its actually to cut somewhat irregular shaped interval slots.
Sweet! That’s an excellent use case. Glad you’re finding it useful 🙂
Did you produce a build video ??
Not yet for this one. I’m working on an improved design and intend to offer plans for it soon 🙂
do you have the plans for the improved version yet?
Are plans available for the improved version ?
Looks good! I intend to build a large toolcabinet with excessively high sides that this would be perfect for. Can’t wait to see the plans.
Are plans available for the improved version ?
I’ll echo the last few comments: Are the plains available yet?
How’s the build video for this box join jig coming, been waiting forever it seems.
