One of the key design features of this project is the three-way half lap joint, a joint I learned here on Lumberjocks. I’ve been practicing making them on scrap. After making my 120° sled, I started out on my own. I just tried to figure out the cuts on my own. The result wasn’t terrible, but it was clearly not the best method. So I went back to the thread on LJs and found the youtube video that shopbuilt posted, and I learned the trick to doing this much easier, so thanks to ShopBuilt.
Here’s a pick with my first two efforts (after being cut off) and then the last one I did. I did put a little timbermate in the joint to see if I could clean it up just a bit. For me, the trick to the tick joint was to use the table saw to get 95% there, and then use a chisel to pare away. I think this will work.
