Anyone ever do blind box joints?

Seeing Bandits post and how he was doing them and got me to thinking about if they have been done and wondered how strong they were.

I also thought they may look nice to.

Box and dovetail joints are versions of the same joint, mortise and tenon(?). I keep finding a progenitor of what I read as the parent of those joints, so never know. Selection of one or the the other for use is a matter of esthetics and convenience. Obviously, converting to a blind, or half-blind joint compounds the difficulty of fabrication, which can translate to kudos for the builder, or frustration.

Regarding strength, I would say the dovetails are strongest, only due to mechanical advantage. A full through joint is the strongest simply due to greater long grain to long grain surface area for gluing. I think the hype for dovetails strength--as we view them--is overblown. A sliding dovetail is probably the strongest joint; but we can't gloat over those since they were favorites of mass production; as are finger (box) joints.

Arlin, take a look at this, starting at the 4:10 mark https://m.youtube.com/watch?feature=relm...wzeONtOAFg

As Bruce says, there's not much difference between the dovetail and box joint, as the casual way they're made in the video pretty much confirms. Bear in mind that I will never rise to the level of skills displayed in this video series.

Arlin, I was thinking the same thing. Use a mortise machine to make a bunch of evenly spaced mortises, then use the table saw to make the row of tenons.  If one were to make them 1/2" deep in 3/4" stock, I would think there would be plenty of edge to edge gluing happening to make a strong joint.

You may get a stronger joint in the state of Colorado, but that conversation belongs in the basement  Rolleyes
I tried not believing. That didn't work so now I just believe.

had to check to make sure I was still in handtools

seems like blind box joints would be marginally easier to make than blind dovetails, because you don't have to chop out the corners.
But if you are going to cheat on it, I like the shop made veneer method.  Just make through box joint and glue a shop made veneer over it.  FWW had that in a recent issue for blind dovetails.

In bold is what I was thinking to.

I grew up in Evergreen Colorado and went into the Air Force in Denver but never did that Joint thing and never will.

Sorry.  I got here from the "Welcome" page, and not the normal menu.  I was not paying attention.  Sorry   Uhoh

Arlin, I would use a brace to hog out the material, then use the mortise chisel, the one I use with the drill press, but with a mallet, to square up the small, individual mortises.  

Hope that helps.

To me it is not how you get them out since there are as many ways as to how many people who do them.  I also was not comparing the Dovetail to the Box joint but just if anyone seen or did a half blind box joint and if it was still a good rock solid joint after the glue was applied.

To me it would be easy to use a mortise gauge or marking gauge whatever it is called between the two of them and then being able to cut two of the boards at the same time to save well time but not the blind part.

On the blind dovetail or box joint I think the joint not only goes part way up the board but half way or three-fourth's of the way thru the thickness of the board also, correct?

In my opinion, with a 1/2 blind, one will see the fingers from the side, but not the front.  In a full blind, one will not see the fingers.  Basically it is a mortise and tennon, or rather a series of mortise and tennons.

Hmmm, got me to thinking...... Uhoh Dangerous, I know.... Winkgrin 

After a certain box is in the clamps...I might have a bit of scrap wood laying about Rolleyes  and might give this a try out?    3/4" pine?  Joined to another 3/4" pine?    There IS one way I could try out...... Raised Raised Cool 

Need to "hide the joint"?   Maybe a "miter joint-like" thingy?     Give me a couple days, though.....
Show me a picture, I'll build a project from that
