Hi all and thanks in advance for whatever help you can provide. I recently purchased a tandem (1952??) that was stored in a garage for decades. The rims are now soaking in molasses and I want to get started on cleaning the cranks and regreasing the bottom bracket bearings. I don't really want to use a channel lock on the bottom bracket nut if I can avoid it. So does anybody know the size of the nut and a good wrench reference?
