I built up a few tandems with Phil Wood disc brakes too. Wasn't there a special lubricant that need to be applied to the splines of the disk and hub?

I seem to remember one that had problems but I think that it had been set up by the owner???

We found a good connection for Maxicar hubs and went that way instead of the Phil Wood hubs.

The first few 48 spoke Phil Wood wheels that we built were trial and error because there we no guidelines at that time.
