Are the leading and trailing edges chamfered to prevent cutting or wearing the belt?
No, they do not arrive chamfered from us, this is something the user will need to do if they want. You can do this by roughing the radius in with a coarse grit belt (1.e., 80 – 120 grit), and then cleaning it up with a fine grit belt (i.e., 220 – 400 grit), or until you are satisfied with the smoothness of the transition region. I prefer to use the slack belt region of my grinder to do this operation. In addition, some people choose to radius the edges or parts of the edges to assist in attaining different plunge cut geometries. For instance, I have known people to leave the upper half with sharp edges, and radius the lower half edges. This way you can have a sharply defined plunge cut by using the upper portion of the platen liner, and if you desire a more sweeping plunge, you can use the lower half. It is up to the user to determine if this is something they want to be able to do or not.
