A couple of years ago my grandson Nesta started taking guitar lessons.  He practised on his mother's old classical guitar.  At one point he asked if I would make him an acoustic steel string  guitar.  This was the beginning of a new adventure for me.  I bought a couple of books on guitar building  and also spent quite a lot of time on the internet trying to educate myself.  I had  to decide on a shape for the body,the scale length, etc. and then make full size drawings.  I also had to find sources for all the materials and obtain them.  Fortunately, British Columbia produces some of the best spruce wood for guitar tops in the world.  During my times in Germany I have been able to visit a couple of times a very good wood supplier in Frankfurt and purchase rosewood and other species for backs and sides. I also built some specialized tools and equipment including an eighteen inch drum sander to thickness the tops, sides and back.  Building the guitar took me many hours but it was a wonderful and satisfying experience. I have now begun a second and third guitar.
