Good, yes first and last are the same arch, reversed. If you notice on photo 2, I make the chalk marks on the inside of the arch. If you blow up the last photo you see there are no chalk marks on the inside, 'cause they are now on the outside.
I have a number of attachments that I have made for the press, I have used it for pressing cartridge type wheel bearings, and straightening any number of items, including every bent tankers bar in the neighborhood. I formed some of the parts for my current speedster with it. Not quite a shop press, but real handy for the $80.00 it cost.
