Good for you, sharing the hobby with your Bud. Just as he decided to ask to build one, with encouragement from Dad along the way, he can be the one to decide to or not. I see these posts ever now and then, I love seeing a youngster taking his/her first steps at Dad's bench.
I hope he'll continue, it will make for some very happy moments in your lives. Thanks for a very nice post and for the photos.
