He offered me a job, but I finally decided not to go in that direction. I did build a one-rank pipe organ for myself, which I kept for several years and then sold. However, as a lark, I designed a small portable 2-octave organ that was well within the capabilities of a home craftsman. At that time I was designing woodworking and other projects for various magazines.
I convinced Popular Mechanics to buy an article on that little toy pipe organ. The article was published in 1982. Many years later, while searching YouTube for organ videos, I happened upon this video:
Someone had actually built the project and made a video of the finished item. I suppose others built it, too, but I had never seen one that wasn't the prototype I made. I contacted the person and he wrote back. Apparently he made several of them as gifts for grandchildren and went on to make some larger instruments as well. Very nice.
Here's the Popular Mechanics article, which I was surprised to find on the Internet, too:
