.680 -.500 = 180 thousanths :) A few? :) A bit crude isn't it Kevin? :)

Paul, not a plumber are you? :-) 1/2" = ID in pipe. Still crude just not quite
as bad as you might think. Bill Jepson

My mistake. I stand corrected. I thought that applied only to cast
iron and pvc pipe. In that case Kevin I apologize and take it all back.
Damn good idea. I'll have to mic the OD on 1/2 inch copper pipe.
I tried 5/8 (.625) bolts and they were kind of sloppy.
What is the OD of 1/2 inch PVC pipe?
