After getting several brass tubes, used in pen turning, mixed up, I came up with this sizing block. A few years later I found that reading those tiny numbers on my drill bits was causing more frustration than they were worth and realized the sizing block would work for them too.
This is my third video for 2014. Hope you enjoy it.
