All right guys. First i have to apologize, sometimes i snap and become mr Hyde but usually I am dr Jackyll.:))))) But that's ok because i have license to snap from Norbert :))) second i want to give you a tip so you don't have to go through same thing i did. When Paterson guy shows up to replace the suction sensor on your Mcx5 don't let him go before you mill at least one crown. The new sensor sometime doesn't work. Third thing I want to admit I am very pleased with the quality of the mill after we got the 15 sw. Fit is extremely accurate.
