Growing up we made lots and lots of sausage. My family raised our own beef and pork and butchered it too. My dad bought a meat cutting saw and a grinder for doing all kinds of ground meat with a sausage attachment from a butcher shop going out of business .    
 
 The only piece of advice I have is when you season the meat, cook up a small amount of the meat to make sure that the seasoning is "right".  If it tastes good then finish the sausage making, if it needs more seasoning add it and cook another bite size piece.  Next time you make the sausage you won't need to cook a piece, you will know how much seasoning to use.
