kbh-<< The plastic lockring on my relatively new UN-52 bottom bracket is
stripped and won't thread on snugly. Is there any source of replacement
removeable rings, preferably aluminum like on the UN-72, for Shimano BB's?

Yes you can use one from a UN-72 and most decent bike shops have them, as do
we. Call us

Use this technique to help keep the next one from stripping.

A rear skewer and some washers. Use a 8Mx1 bolt on square taper BB's to
hold the tool in place.
