A few people mentioned making one of these long boards with a built-in "fence" to ensure accurate cuts every time. Here is Ted Sobocienski's version.

Jerry Ormes has the same idea, but also sent over a Sketchup file for you do download.

I really like David Higgins' system and may make one myself.
"I made this system for beaking down sheet good, you just set up on saw horses. The grid system allows you to cross cut or rip cut, and your work will always be supported, also the system breaks down and leans against a wall when not in use. One other feature is you through a sheet of ply on top, and you have a great work surface."
I have one of those circular saws. That is a Porter Cable 743 left hand sidewinder isn't it?

Steve, I made a setup like David's. Very convenient, stow-able and breaks down easily if it's not to tight. Great for job sites.
ReplyDeleteIn the UK at B&Q, which is our equivalent to the US's Home Depot I think, you just give 'em your dimensions and they cut sheets down on their panel saw, free for two cuts. I only buy ply sheets for specific projects so this is perfect for me.
ReplyDeleteI do basically the same as Gareth. I have 'em cut the sheet in half if nothing else. Sure, There may be a little waste but at 65 I'm no spring chicken and even lifting a half sheet of 3/4" onto the table saw is getting to be a chore.
ReplyDeleteThen there's this guy who put way too much thought into his setup:

It is pretty nuts!
Ted's fence system can also incorporate a router. You cut one side with the circular saw and the other side of the fence with the router! Now its a 2-tool jig :)
ReplyDeleteAll these suggestions for breaking down plywood cut it up.
ReplyDeleteTo really break down plywood, you need to bend the sheet so severely that it snaps in two. Only THEN will you have broken it down.
C'Mon people. Learn how to "break down" plywood correctly!! USE A SLEDGHAMMER!!!
Ted's setup is sometimes called a shooter board by finish carpenters. It supports one side of the cut line, which has the same effect as a zero clearance plate. Very easy and efficient. Thanks for sharing all of these ideas.
