As I mentioned in a few earlier posts, I created the tenon's on the aprons a little over 1" in length. This means that the tenon's are either too long or need to have some scheme to take up the same space inside the mortises.
The 2 approaches I considered include:
- A miter joint between the tenons
- An interlocking finger joint
I decided to go with the interlocking finger joint.
The first step is to insert a tenon into it's mortise (I've been marking each tenon and mortise with matching letters to keep track of them). Then through the other mortise, I mark how much of the tenon overlaps with it's mated tenon. I then decided the width of the finger joints (in my case, 1 1/8") and marked them. Then I used a saw and chisel to cut and remove wood. I followed it with a few chisel cuts to size the finger joints with some test fits in between. The goal is to keep the shoulders of the aprons to be tightly flush to the legs.
Here is how one turned out.
I progressed around the desk's base and finished each tenon. This now allows me to dry fit the desk together.
Next, I will come up with a glue up strategy. I am planning to pin the tenons with dowels but my goal is to achieve a square glue up. I can then work on the drawer rails. Once the drawer rails are done, i'll turn my attention back to the top.
