Like this a lot. I've similar plans to make a Star Wars clapper, so i've been watching your threads with interest.
Couple of questions.
1. The slot in the top clapper. What is that used for, and did you cut it out or make the top from three pieces of wood?
2. What did you use for the back? I was going to use blackboard paint. Seemed to make sense if i was going to be writing on it in chalk
3. How did you do the white lettering and lines
