Some photos are in order, as I actually don\'t understand what you mean when you say you are attempting to \"remove the filter rings\". On most lenses, there is a \"name ring\" that is threaded into the interior filter threads (of the front barrel). This \"name ring\" often holds the front element in, and then possibly other rings or assemblies are threaded into those same threads further back.
On the Rokkor, the \"name ring\" is not what needs to be removed. Rather, there are two fine rings on the inside of the filter threads that need to be removed. They have notches, so you can use one of these to remove it (spanner):
I use a pair of small needlenose pliers that I filed to a point for this purpose. Simply adjust the pliers (or spanner) to fit in the slots and then (carefully) turn the ring.
For \"name rings\" which don\'t have slots, I have used a roll of cheap hockey tape. Simply remov enough tape from the roll so it fits, jam it against the \"name ring\" and then twist. The glue provides ample friction and can be cleaned up fairly easily later.
