What is the best way, well, easiest way, to square up a piece of plywood? I have several pieces that I used a jigsaw to cut windows out of a full sheet of plywood that I used to sheath the walls in my workshop. I'd like to get these back into square to use them in smaller areas on the walls.
I have yet to build a sled for my table saw which would probably be a great way to do it, so in lieu of having that option, what other techniques are available to me?
I do have a track saw and thought about just laying the track down on a path that looks pretty straight then going to the table saw for the other sides. Another idea (that I've seen some videos on) is screwing a straight edge to it and running that through the table saw.
Appreciate any tips I can get! TIA
