Does a ring hole have to be round?
I’ll explain: Let’s say I want to create a size 7 ring, which means
the diameter should be roughly 17.3 mm. I file the hole on a ring
anvil wrapped in sand paper, while checking the size with a caliper.
Problem is for some reason the hole doesn’t come out perfectly round
- while the diameter between two points is 17.3, between other
points it may be 17.1, 17.4, etc.
Does this matter? will this bother the person with a size 7
Can anyone share his or her method for creating “the perfect
Thanks in advance,
