It is a masterpiece Tom and thank you for letting watch you build it.
I had that can't do attitude when I was on a forum and a guy built a 20 note hand crank organ. He told me I could do it, so I bought the plans, but still thought it was beyond my skills. I had the plans for two years, watched others on the forum build them. Finally I decided what the heck, I can start, it is only wood, if I screw up get more wood and try again. Once I started, I became obsessed with it. Still took me 7 months to complete, but it was pretty much all I thought about for that time. I had the motto, one part at a time, when that is done and correct, do another part. Seemed like in no time I had a lot of parts, each became easier because my confidence was building right along with the parts. It was unbelievable the first time I turned the crank and music came out. Honestly brought tears to my eyes. Probably the biggest thrill in my life next to holding my new babies for the first time. Looking back, none of it was really that hard.
Congratulations on your great build.
