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
Forget this weirdo. You guys wanna see something really neat? I just have to take off my shoe .... (hint: it's a tiny ad)
