I purchased plans for strip cutter. I am diy challenged any help would be appreciated. What did you mount this too? Plywood? I did notice some responses for MDF. Just curious what others might be using. In the You tube video it appears to be mounted to some type of board and it looks like a morton based was placed on top of the mounting board. Is this correct? If you use the centering ruler, do you need to cut it in half? Any construction problems or tips?
