[ARC5] Removing plug retaining rings

[Steve Williams]

I think you're dealing with 75 year old aluminum corrosion.  Acetone won't
fix that. I have dealt with the same thing with no luck so far. If you dont
have a special pair of exact fit pliers, you're pretty much screwed, unless
someone else has a better solution. I do have the knurled rings for sale on
ebay, but you'll need to come up with a way cut the old ring off. Very
carefull die grinder work to cut the ring only may work. I also have some
of the more common recepticales listed. I may have an odd receptacle in the
junk box as well. You may only have to weaken the ring in order to remove
it. If I have the receptacle, then you can cut through both and replace
both.
Good luck.
