As noted there is a few resources available to show how to sharpen the big crosscuts. The "one man saws" I have are capable of taking a handle on the other end..
The dry wood will cut harder as the fibers tend to break off as opposed to green or wet tends to shear. The rakers actually are supposed to be shorter than the cutters, and they should be tapped over to get more of an angle...think chisel cutting angle. As with all saws you can set it up for hard, soft or both...or buy another saw so you can have a hard and softwood saw.
Come on up to Taylor Mill in Derry with the saw and I will see if I can help you with it. Saturday the 24 is a cutting day, but at the rate the water is dropping...maybe not.
