Thanks for the up date, Ray
Last week, I updated my oil pan jig (a three inch tall box the size of the inside of the oil pan), I added a piece of plywood the same size as the inside of the pan. I cut the metal, mark the pan edges, put it on top of the jig, put the plywood on top of the metal, center it and then I use push clamps using the cabinet above the table to push down on the plywood to lock the plywood in place. I then use a bar to bend over the sides. Worked out real well.
