I've just used two teeny tiny drops of superglue spread with a toothpick and it seems to have made a very solid connection. It's held very strongly in place and spins nice and smoothly. Still need to run a roll through but things are looking good. I wonder why Mamiya had them as separate parts where previous models didn't do that? Anyway I've put in new light seals too so the whole thing should be set for a "real" run soon! The weather in Sydney's been a bit dreary lately—great for taking photos with a camera that I can keep out of the rain under an umbrella, not so much for the RB67 which is too heavy for me to carry for more than a few minutes
