First off, where are you located? If none of the local shops or makers will take you on, then I suggest you wait until you graduate high school, then attend one of the violin making schools in the States or abroad. I graduated from the North Bennet Street School in Boston last year, and I had the time of my life. Sure it had its ups and downs, but you power through it; and if you have a good work ethic and an eye for the craft, then you’ll find the experience very rewarding.
The other schools are in Chicago, Salt Lake City, Red Wing in Minnesota, and at Indiana University. I don’t know too much about the other schools, but a significant advantage over the others is that you are allowed to keep your own instruments after you finish them. At the other schools, the instruments become their property upon completion, and you would have to buy them if you wanted to keep them (laaaame). The trade-off there is in the tuition.
The entire violin making department at the North Bennet Street School is about twelve, which includes the instructor, Roman Barnas, who is an extremely excellent, excellent teacher. It wasn’t until we had the occasional substitute instructor that I began to really value Roman’s ability to impart his knowledge of the craft.
If you find the time, go out there and visit the school or any of the others, especially during the academic year when you can hang out with the students and ask them questions. If you don’t have time, then MAKE TIME! If lutherie is a serious possibility, then start looking around to get a better idea of your options and where you might want to be by the time you graduate. You might want something completely different by then, but I’m all for preventing others from ending up in a cubicle.
