Pinning on new flanges

[Bob Hull]

Here's more detail on the pinning condition:
The thinnest treble shanks swing in the 5-6 range. 
That's acceptable. The medium thickness shanks
swing6-8. The bass/tenor s/f swing mostly 8 - 10, some
7.
This doesn't seems as bad as the original checking I
did of the first 20 or so which seem to be more loose
than the rest.

Question: when you swing a hammer do you test by
swinging the shank from a 90 degree angle to flange or
less?  It seems to make a difference of about 1 more
swing?  Also: do you count even the last couple of
very short swings?

Thanks for any input.
