Greg, Unless I am reading your sketch wrong I think there is an error on the third drawing of the pencil box with the lid. Take a look and tell me.. The sketch in the lower left corner is showing both ends of the sides?
I wish I had but my pencil box caught it… 🙂 I made one today using just hand tools. It was great! If I had to make a bunch of them I’d probably go back to the table saw but getting it square was fun… I looked up and it was dark outside… My wife had hobbled out and fed the horses. (she has a broken ankle). But when I handed her the box she hugged my neck! I’m liking this stuff more every day.
The hardest thing to get the hang of is not breaking the ends of when planning end grain.
