Wood: If you were to make the 4' cross pc a few inches wider, put a strait pc of hardwood on it and rip the pc with your saw than you would have a guide that is EXACTLY on your cutline. just make your marks, clamp it as you do right now and cut no measuring at all:yes:
Great jig idea tho. I got tired of em and bought a slider attachment for my saw :}. I just ruff rip em then finish on TS. It is a few extra mins and cuts but soooooooo much better and easier for me.

Square is RELATIVE. Lets say that the Jig is square and you referance off the top factory edge, and crosscut the sheet. Well you now have two edges that are SQUARE to each other and can now be used to square the remainder. As far as blade I use a Freud 60 tooth fine blade and it rips fantastic and crosscuts the same, no problems. Always cut good face away from the saw and with the Jig you will have a virtually chip free cut.
