Alternatives to Fighting

In progressing the standing desk build, I had to make a design choice regarding how to attach the back stretcher. But, more importantly, I had a practical choice to make. The angle of the back leg on each of the two frames is slightly off. Call it half a degree or so. Near the top of the assembly, there is no appreciable difference. 30″ or so down the legs, though, it’s nearly 3/16″ off.

I could, in theory, modify the cheek depth on one of the tenons and cant it very slightly to correct for this discrepancy. Or I could just run the stretcher near the top where the bag legs are, for all practical purposes, parallel. And if I’m doing that, why not in my impatience just lap a dovetail?

Because of course dovetails.

Half-lapped dovetails are an interesting joint. I personally find them aesthetically displeasing, even when executed perfectly. But they provide a mechanical resistance against tensile force that in other joints would require some sort of fastener (dowels, screws or bolts). And, like the comparable joints (mortise and tenon, half lap joint), they have significant long grain to long grain glue surface for maximum strength.

Plus, I find them rather easy to cut once you dial in the compound angle.

Ugly or not, this particular joint is not only on the back of the assembly, so I don’t have to every look at it again. Plus, it will be painted. So I’m happy with the choice.

Now I just have to make the top.

Have I mentioned that Eastern White Pine is just the best? Because it is.
