The box joint appeals the most. Simple is good but, not a fan of dowel joints.
I just don't care for them either. However, making a frame for shade cloth, using 24 inch lap joint, I did drop several dowels through the joint to add a little reinforcement....not a fan of dowel joints.
4D, I love dowel joints. :grin: It is different and I think making something is what it's all about.The dowel version is essentially 3 through tenons cut in the end grain of the joining board. Using the CNC I could have stretched them, made them triangular, done a zig-zag row of short tenons, etc.. I made them look like wood plugs (or hardwood dowels) when assembled because that is how we originally asked the students to reinforce/strengthen the shallow rabbet joint. In the future I may scrap that joint and replace it with a simple dovetail row. Through or half blind.

Absolutely.... I think making something is what it's all about.
