Matt,
How bad is the ridge? I have a reamer you can borrow if you want to... But you want to be very careful to only remove the ridge without hitting the ring sealing area. The issue is the sharp corner of the new ring impacting the rounded edge of the step and getting damaged.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
