I've got a set of those pliers. If they weren't fairly good for reaming 1/2 and 3/4 thinwall, I'd send them to you for the price of shipping.
If you use them, be careful or use fairly thick gloves. You (I) generally have to use fingertips to hold the jaws down on the locknut, and they tend to bite without warning, when they jump off the locknut.
Often.
