Great video, Tommy. I watched the whole thing from start to finish. I was very impressed by some of your techniques, and templates you used during the build. Back in the day I worked with a guy in Oklahoma, and we built resiphonic guitars (they were known as DoBros), and we built all the jigs for all the parts. My question is: What was the purpose of putting the f-hole sound board on the back of the mandocello that sat on the little blocks.? And what was the small tool (it looked like a mini router) used to rout out the grove for the binding.? I also built an F5-style mandolin patterened after an old Gibson mandolin…I think I told you that some time back. When I did the mother of pearl inlay on the peghead and neck of the guitars, I cut it out just like you did with a coping saw, but used a Dremel tool to cut the pattern to inset it in the neck….!! Anyway I enjoyed watching the video, and following the build.
