If your 14" is a woodcutting bandsaw,you will have to slow it down with pulleys.Metal cutting bandsaws run at a speed of 100-200 fpm,woodcutter at 1500-3000 fpm.Friction cutting metal on a wood saw is an option,but you would need to get the speed up to 5000fpm +,and I am not sure what type of blade to use in that application.For regular metal cutting,a 14 to 18 tooth BI METAL blade (depending on the thickness of your stock)will work fine.
I am going to cut metal patterns no thicker that 5/32. I think I will go with a grizzy metal cutting band saw for 199. They had a 14 inch for 279 that I thought I might cut wood and metal without getting into the higher priced saws. The 14 inch had a cast iron frame.
