J.R. Beall has been a fine woodworker for many years.
He began building musical instruments in 1969, making more than 800 dulcimers, hammer dulcimers, guitars, harpsichords and more. He continued as a professional woodworker for many years, during which time he built clocks, furniture, giant wooden tools & wooden machinery. In 1982 he founded the Beall Tool Company, & holds several patents for woodworking tools he developed, including a wood threading device. The tool company occupies most of his time now, but he still does woodworking for fun. He loves the challenge involved in constructing complicated wooden mechanisms.

A note from J.R.:
Just dicta your web site and it is very impressive. You deserve great credit for all the work you have done in spreading the word on clock construction and design.
I have been messing about with clocks for some years and am currently involved in a sustained binge of clock building.
I found it curious that you have not had success with making your own plywood. I have been doing it for a long time and never had a failure. I have used all types of exotics and glued them with West System epoxy using a vacuum press. I have a 15 year old grasshopper with laminated bubinga wheels and pinions that has performed faithfully since it was made.
I have a CNC mill and home made made CNC lathe and have found a book called "Gears for small mechanisms" which does a good job of presenting the formulas and geometry for cycloidal gearing. I like to make very small and delicate wheels and have found that .055 imperial module is about as small as I want to go. That will give me a 10 tooth pinion of about 1/2" diameter.
It seems to me that someone should do something about organizing the wood works clock nuts and having a convention. I would be glad to host it. Many years ago I started The Guild of American Luthiers in this way and it has become a large and popular group. It would be wonderful to share experiences and techniques with others face to face.
I have been doing kaleidoscopes for several years and some of them are gear driven.
Incidentally, although I agree gearing should not be finished it does look and perform a lot better if it is buffed with our buffing system (plug).
Thanks again for all your effort,
