Yesterday's joints came out both tighter and worse than my first joints. Measuring was the primary issue. I didn't scribe my lines very well. I think that I'll do better if I change my knife as a box cutter isn't quite giving me a nice enough line. The next time that I'm to a hardware store, I'll have to pick up a scribing knife.
Don't believe for a second that I'm doing a first class job. I'm not. This project is for me to develop skill and make mistakes, and I guarantee you, I am making mistakes.
