That's where the Machinist comes in. He is going to cut and paste. He will be cutting some of the trays and pasting (welding) them on to other trays to create a larger batch for the dessert pies. The meat pies are a different story. For them, he is going to manufacture a tray big enough for each deck of the oven, cut holes in it (like an egg poacher) and we will purchase loose pie tins to fit in the holes.
This pie pallet / pie tin ordering has had me flumoxed. I am no mathematician and don't have much of a logical brain at all. That's where the Machinist comes to the rescue again.
Ah, the Machinist. What would I do without him?
