I scarfed all of my plywood by just placing the plywood edge on the edge of a table layed a piece of angle about 6-8 inches back from the table to clamp the plywood down and hold it in place then measured back 1" from the edge of table/ply and drew a line. Then with belt sander in hand worked from the edge of the table back to the line. It make a good scarf and if repeated with all ply it will fit anywhere you have a joint.
