Today I received the 42mm Columbus LIFE down tube I ordered from Nova Cycle Supply and was able to finish mitering the front triangle. This will undoubtedly be the stiffest frame I have built to date. The OD on the head tube is 36mm and the OD on the bottom bracket is 38mm, so I had to ovalize the down tube in opposite axis to be able to have complete miters. With the height of the down tube at the head tube joint so tall, I had to add a double miter to the top tube (essentially relieving it where it intersected the down tube). Before welding I added the cable guides and sealed bottle bosses to the down tube. I think I may have executed my best welded joint ever on the seat tube/top tube joint. As with frame 055, the seat stays are the last to go on and those will get welded Friday.
