I covering off the side of a barn next weekend and need to run about 20 or so 3/4in. plywood. Much to my dismay, my partner bailed on me and I will be doing it myself. Because the side is so short in height (and wide) each piece needs to be cut down to about 23in. I just started up my new Proshop and would like to devise a jig to cut my plywood quickly and safely by myself. Any suggestions? Ready made jigs you know of?
