I decided to give myself a little challenge. This has nothing to do with the brotherhood thing - its just something I want to do with myself. It might fail dramatically - you'll know if it does. Background. My first guitar was built in 2014 from plans from Stewart McDonald and the classic book by Cumpiano and Natelson, Guitar Making - Tradition and Technology (I like that title, think about it a bit). The book is mostly just known as Cumpiano - thats how I'll refer to it here. Cumpiano takes the reader (and beginning builder) thru the construction of two different acoustic guitars - a steel string similar to an OM and a classical similar to a Torres or Hauser. I used the book mostly as a guide of how to do things, I used the SM plans for dimensions. The guitar came out pretty nice, actually pretty amazing considering everything that I struggled with, and when I showed it to my son (the same one) he said "dad, if you ever want to build another one I would love a classical..." Well, since I had the other half of the Cumpiano book that described building a classical and since the GAL had classical plans and since he was my son, after all, I said what the heck and built a classical. Here are the two guitars - 16 years ago. The plans for the classical are the 1937 Hauser that Andre Segovia called the greatest guitar of our epoch". That sort of got peoples attention and this guitar has been studied and copied probably more than any other single instrument in history. The beautiful plans were (hand) drawn by RA Brune after taking detailed measurements from the guitar, I followed them as closely as I could. After building those two guitars I figured I knew everything about building guitars and put Cumpiano on the book shelf where its been sitting until last week. The library is shut down and I've read everything in the house - Cussler and Tolkin and all of my back issues of Fretboard Journal and American Lutherie. As I worked my way down the pile of guitar books I found Cumpiano, dusted it off and started reading. And got inspired. Why not build another classical guitar? But set some constraints on the way I build it. First of all, could I build it out of materials that I have on hand? I have boxes of wood and scraps and cutoffs and stuff - this would be a chance to use up some of it. So first challenge, build with what I have. Second challenge - could I build this with the minimum of tools? Over the years I have added fancy new power tools and gizmos to make building easier or more accurate or better - I have a policy of looking back after a build and thinking about a tool that would have made it easier and adding that to the tool bench. Could I do it entirely with hand tools? This kept me away several nights, I'll come back to it. Third challenge - could I build it with hide glue? That doesn't seem like a biggie to you folks who have mastered HHG and those of you who have never tried don't understand what a complex subject that really is. Hot hide glue is the traditional glue that was used in the 1600's and 1700's and .... right up to maybe the 1930's when modern glues pretty much replaced it. Hide glue has some huge advantages for instrument construction but it is simply a hassle to work with. It has a very short "open" time, you can't fiddle around looking for a clamp or moving pieces if they don't align perfectly. I use it from time to time when I feel it is necessary, but I've never felt I has mastered it. This would be a good time to practice. Forth challenge - the best finish for a classical guitar is hand applied shellac called French polish. Once again, it is a technique that needs to be mastered to get the kind of finish you see on vintage instruments. I haven't mastered it either, another good thing to practic. Coming back to the hand tool question I decide that it was silly to try to build a classical guitar with a pocket knife. Some of the hand tools I would need (like an egg beater drill or a bind grammil) I don't currently own - seems kind of silly to by a hand drill to make six holes for tuners. So I compromised my second challenge - I will use only tools described in Cumpiano. If he used a band saw for something then a band saw is fair game. If he used a powered drill then I could also. He actually does use a router for binding, that opens up a big worry. No air compressor, no problem. No CADD or CAM or CNC in site - good thing 'cause I don't have one.
