Rebuild Snag

Hey guys!
Started rebuilding my ultra low time Aerovee to convert it (at the factory’s recommendation) from a 2002 to a 2.1 so I can utilize the turbo. The bore measured good on the cylinders so I opted to throw new rings in and reuse them. Got most of my parts from Sonex or CB performance, no eBay parts here!! However, the new piston rings I received from CB Performance did not meet Sonex specs. My ring end gap ranged from .005” to .007”. Manual states the gap should range from .012” - .022”. Since I didn’t have a ring filer and didn’t trust myself to make a square end on the rings with a hand file I decided to take them to a local machine shop. My question is for you guys that rebuilt, did you ever have too tight of a gap for the rings? What did you do to fix it? Did you decide to go the machine shop route as well or am I being too obsessive compulsive?
