Here's a bit of information on the pan. Except for the very deepest pocket all of the other walls are .06 thick. The bottom is .110 because it needs threads for the drain plug.
As I have mentioned along the way, when making parts from bar stock the inside always needs to be done first. With most of the parts I'm making a fixture plate is also needed. At this point I have three, 2 of them serving double duty for other parts. It seems like a waste of material but some times there's no other way to hold a part for machining. Usually if a part has clearance holes for mounting screws I'll drill and tap them for mounting to the fixture plate and then go back and clearance drill them when I'm all finished machining the part.
