I've included a video to see the situation before me. I have a horizontal crucks log which is ~15cm too short which I must connect to a corner post. I'm thinking I need to create a custom connector to tenon/mortise into both pieces. If my understanding is correct, this joint won't hold structural weight but merely serves to hold it together
I didn't do it. You can't prove it. Nobody saw me. The sheep are lying! This tiny ad is my witness!
