Corrections For Aaaargh & I Spec Someone Does

[David Boyce]

"at the same time the pin is tapered and a thicker portion of the pin has 
moved into a different part of the hole along it's entire length".

I wasn't aware of tuning pins as being tapered.  Of course the *square* is 
tapered, but surely the threaded part which goes into the pinblock, is 
parallel?  I just measured on and it's parallel along its length.  If it was 
tapered, how would you know where to measure, to get the correct thickness 
measurement for ordering new ones?

I understood the principal active effect of driving the pin further into the 
block to be that the end of the pin would now be gripped by a "fresh" 
portion of the pinblock hole which had not hitherto had any pin in it and 
therefore stood a better chance of gripping.  I can see that the disturbance 
of driving the threaded pin along the hole might also disturb pinblock 
fibres in a way that cold cause them to grip better.

Best,

David.
