Before and after shots of the drive side seatstay braze on.  Even though I use an alignment fixture to set the stays relative to the front triangle, I like to use a true and centered wheel to tack the ds stay.  paranoia, I guess.  I set the stays as wide as possible on the seat tube lug and still be considered fastback.  Dave wants lots of room for wheel and fender clearance.  Also, you will see a fat silver edge at the seat post port.  I like to put a radius or a chamfer  there, just think it looks good.
