As you can almost see, the seat tube/down tube angle of the bottom bracket shell is  60' and Robins frame needs  55.6'.
 So, I have some pieces of water pipe sleeved with scrap frame tubing and I muscle the BB to close up the angle.  I'll get 2-3 degrees with this and rest by selectively removing material from the insides of the lug ports.
I decided to go ahead and buy the 43.95 mm ream.

We are off to follow the Tour of California......
