I already knew about the French threading problem, since I stripped the threads on the Normandy fixed-gear hub of my Helyett track bike in 1965 by installing a BSA fixed cog.
The old bike mechanic in the shop where I bought the bike simply unscrewed the BSA sprocket, wrapped the hub in aluminum foil, and reinstalled the sprocket. Held with no problem for as long as I owned the bike.
