I'm familiar with the VO and milling options, and I knew that either would be cost prohibitive, so I think I'm going to have to take a chance with a No5 spindle, or search vainly for a No7. Every one I have is a No3. . .
I can't remember where I read it, but once I saw something about MTB spindles being made for wider shells, and if they're JIS taper I was thinking it would go. Ah well.
Apart from paying through the nose on eBay for an Italian bb, I may just stop by the coop and nose around, or alternatively, just stick with cottered. (I'm doing this for a flip and already I won't see $25 margin on it, even in the spring.)
Thanks very much all.
