Big Table Saw Sled

I have been working on a door. I needed to square up the ends of the door.  I made a big table saw sled for my Powermatic 72 to perform this function.  I started with a sheet of half inch birch plywood. I cut this to 30 by 48 inches.  Then I made a rail from hard maple that fit in one of the slots on the table saw top.  I planed it down to where it just fit in the slot with out wiggling but still could slide easily back and forth.  I attached the rail parallel to the shorter side of the plywood.  Then I trimmed off the shorter side closest to the blade to make that edge of the plywood perfectly parallel to the slot in the table saw.  Next I attached a stop to the back of the plywood piece with one screw. I made this stop as perpendicular to the table saw blade as I could.  Then I cut a test piece of plywood with the sled. With this cut I could test how square the sled was. I adjusted the stop and got it spot on.  Finally, I turned a handle on the lathe for the sled. This made it easer to push.
