restoring freewheel threads on a hub

[halyes]

I found buggered threads when putting a freewheel back on the hub, and it started to cross thread.
After reading several suggestions...thread file, knife blade, buy a new wheel, etc....I took an old bottom
bracket lock ring, cut a small slice out of the perimeter of the lock ring (Hacksaw), and spread the opening a little.
I put the lock ring onto the good threads toward the shoulder of the hub, clamped the ring semi-tight with
pliers and used it as a die by threading it off the hub. I spent a fair amount of time thinking about this,
but less than 30 minutes to execute it.

great technique for BSC thread

could not be used for metric which is 34.7mm pitch diameter
metric bottom bracket lockrings & cups are 35.0mm

nor for Italian which is of a different thread pitch

VAR makes or made a die for this; do not now recall if it were offered in all three threads
