Here is another great designed shop machine from the brain of our fellow Lumberjock, StumpyNubs.
This one cuts box joints like no other box joint jig I’ve ever seen or had the priviledge of using before. It is made from a variety of items I had around the shop, plus a few hardware items I picked up at my local hardware store. Unlike a lot of box joint jigs, it does not limit you to one size of fingers. If you can count turns of a crank, you can cut fingers for box joints with this machine as thin or as thick as you like.
The last two photos show four pieces of wood jointed together using this machine. These were cut from scrap wood and aren’t even carefully done as I would while making a project. They are just test pieces.

You can look in my blog section to see more about the build of this machine.
You can go here to watch a video of Stumpy using his machine.
You can go here to buy the plans for this machine. They are only ten dollars and well worth it. I highly suggest this machine to anyone who cuts box joints.

Its pretty cool but it seems like a lot to go through to make box joints? BUT it also looks like its worth the trouble to build because of the speed and simplicity of setting up.

With this & the Dovetail jig, you’re gonna need to make a poject with both joints!!!

Have yourself a cold one, you deserve it my friend!!!

Thanks you two.

sandhill,
Even if it seems like a lot, the joy I get from it is the journey itself.
Besides that, you are correct. In my opinion, it does good enough job that it is well worth it. I built this in about ten hours total, roughly. I have spent more time than that in the last year adjusting the miter gauge setup I had before to cut box joints. The way this machine works, those adjustments will be a thing of the past. Also, with the miter gauge setup I was using, it has gotten to the point where it was adjusted so many times that it needed rebuilt. I’m glad I ran across this machine before I done that.

I recommend anyone who sees this to go see Stumpy's video if you haven’t already seen it. Whatever method you are currently cutting box joints with, I think watching that video will show you that this machine is an improvement.

Thanks DIY.
I’ve actually already had an idea for a project using both machines.
I’ve been thining about building my wife a jewelry cabinet. I’ll bet you’ve seen the type I’m talking about. It’s not something that just sits on top of the dressser. It’s one of those big ones that is a piece of furniture in itself. It has doors that open to reveal drawers and hangers for necklaces on the inside of the doors. That would be nice with dovetails in the cabinet and box joints for all drawers and such.
I have to see how my finances go. I don’t have the lumber stock I want to make it out of. Mother’s day is coming up. If I can get the money up, I’m thinking about making this idea a reality.

I’m going to save this one so I don’t forget. It looks like a good idea.

Looks like you can roll a fair size joint with it…......peace man.

I liked this machine when I first saw it on Stumpy’s video. I like it even more now!
Thanks for sharing.
Well done.

When this design first appeared on my show I got an email from someone asking how it compares with the box joint jig made by Matthias Wandel. So, in case that comes up again, let me address it here:

A lot if jigs out there use a lead screw drive and a sliding carriage. I have discussed my jig with Matthias and am now convinced that he was the first to use a sliding carriage. So I want to mention that, while many have since made all sorts of jigs with that principal, HE WAS the first.

Other than that, the two jigs are very different. Don’t be fooled by the two gears on the side, the gears are only there to raise the crank up to a more comfortable level. You do not swap them out with different sizes for different finger spacing like his.

The way the jig operates, the way the finger spacing is changed, the way the carriage slides and everything else is different on my jig. I also have some key features that his doesn’t have like a quick release and a template feature. I own one of his jigs and it is very well designed. I just like mine better because I believe it is a lot easier to build, and has some extra features that I like very much.

I am not trying to say his jig isn’t a good one. In fact I like his jig very much. Matthias is vastly smarter than I am and a great guy with great ideas. I am only saying that anyone who says my jig is in any way a copy of his is dead wrong. Matthias and I have discussed the jigs and he has even featured mine on his Facebook page and sent a link to my video to all of his mailing list.

Just wanted to clear that up and make sure the credit for the sliding carriage went to him.

By the way, since William didn’t include the template feature on his, I thought I would show what it looks like with the template installed. This is a great feature if you make a lot of the same joints. I made a 1/4” template and a 1/2” template so I don’t always have to turn the crank when I am making a lot of the same joints.

Thanks for the photo Stumpy.
I started to make the template just to show what it looked like, but figured it was alright as long as I provided links where everyone could see your design and video.

I am glad you pointed out that you don’t have to change out gears. I had not seen Mr. Mathius’s, so I was not aware of his having to be switched out.

The top gear also reduces the number of times you have to turn the crank in half. On this machine, this is the way I cut quarter inch box joints.
I “kiss” the left side of the dado blade with my stock and clamp it inthe jig with the fence set so that it stays square.
Then I crank the handle two times to bring it over one quarter inch.
Cut.
Crank the handle four turns to bring it over a half inch. That’s one quarter for the finger, and on quarter for the center point of your next cut.
Repeat those two steps, four turns then cut, until you have all your fingers cut.
Move on to the next piece.
.
Of course, the number of times you crank will change depending on width of fingers you’re cutting. Just remember that for each complete revolution of the handle is ine eighths of an inch. Double that count for the spacing of your finger.
So after making my first cut I’d crank the handle eight times for half inch box joints or twelve times for three quarter box joints. Then again, for small work such as jewelry boxes, you can move the crank two times and cut one eighth inch box joints.
The crank mechanism is simple. The harder part, for me, is getting the width and depth of the dados set right. Since I’ll be doing mostly quarter inch joints though, I wrote with ink on my machine what blades and shims I have to use for quarter inch joints. I’ll be doing the same when I do other sizes. That way, in the future, there will be no guesswork involved.

.

Thanks again Stumpy. This was another great design. I had fun building it and will get a lot of use out of it in my shop.
