Since I'm almost finished with my second build, which I will be putting up for sale soon, I have some questions: 1. How do I protect myself legally? (ie, I sell a bass, then the customer comes back some time later after leaving their bass in a hot car all day, wanting their money back and threatening to sue.) 2. I want a limited warranty on my instruments with a lifetime guarantee, covering things such as previously unseen flaws in workmanship, but not covering damage due to carelessness and rough handling. How do I go about that? 3. Any financial tips would be greatly appreciated. I plan on building 3-4 instruments per year, in my garage, on my own time while still working a 40 hour/week regular job. I don't expect to make much more than a little extra pocket money (maybe 3-5k per year). How do you other part time luthiers out there keep costs down and handle taxes? While it will be nice and quite helpful for me to make a little extra money on the side, I feel the most rewarding part of being a luthier will be seeing other musicians playing my instruments; watching them take something that I built from raw lumber and using it to create awesome music!
