I've seen a lot of threads on cutting speed and and how efficient they can do it and there's a lot of different answers. If I guys wanna play along and post what kind of cutting machine u have and how much horse power and fpm ur cutting speed is and down feed pressure. I think a standard piece of metal to use is 2" 1/4" angle iron. Let's see straightness of cut also. Thanks if u got time to take this test with ur saw!
