muddy waters. one of my favorites, btw. I'm looking at an original 68-ss bottom bracket axle in 115 and a 200x (early) record cartridge bottom bracket. The taper length on the newer unit is 16.55mm, while the older unit has 14.64mm useable length (measured from the inboard end of the little bevel to the end of the taper ramp. I'm trying to figure out whether I can use a newer (2004 or so) crank on the older nuovo record axle. It looks like it'll work, but I can't be sure that it'll tighten down. Anyone ever try to go this way?
