THIS is the culprit for lots of instances where new rings get 
cracked.   You can't have the ridge there; the old rings "wore into" 
that ridge (since they caused it in the first place) and if the ridge 
isn't removed, new rings which are *Not* worn will smack the ridge 
and crack.

Ridge reamers aren't that expensive.   You can also usually rent them 
from your favorite "rent-a-thingy" joint.
