Man those are nice! I really have an interest in making box calls and pots but don't know much about it. I made one box when I was 16 for a wood shop class project. I got a 99 on the call and I've called in a ton of birds with it, it never killed a bird that I called in with it. My late grandfather gave me pointers while I was making it. He was a carpenter for 60 years. I would love to learn to make a call for myself to kill birds with. I imagine that would be very rewarding.
