I believe the "C" is actually for chainsaw... And nope, shots don't work, we won't get into that.... Only thing that helps is a new saw!
Welcome to FHC! Glad to have you aboard. As to CAD, well, good luck with that. The above comment will likely be used against you at some point. I went for almost a year without buying a saw, problem was I bought three tractors, two trucks, and two dump trailers. In retrospect CAD appears pretty minor lol. Glad you're here and hope you stay for the long haul.
