Yes Sir, Like “Go, No Go Gauges” And then measure them. I use Torch tip Cleaners, and a Teeny Tiny Drill bit set, i can use the Shank end of the Bit. But that is precisely how i do it

Between the Tiny Bit set, and This Large Torch Tip cleaner set i have all sizes covered. I can get REALLY Close this way
A Forum member friend sent me the little Drill Bit set and it works AWESOME, Thanks again Willfish
