Nature of tuning pins

[Jon Page]

? Hi Kendall
? Our pin of choice are Blued, Diamond brand pins. On occasions we 
use the Japanese pins.? The difference for us is that the Diamond 
Blued pins clearly have a cut thread that is not blued over & they 
are far more consistent in true size.? The Nippon Denro typically run 
on average .002 smaller than the stated size, which can be a good 
thing when repinning an original block that doens't need a true sized 
pin.? They also make a 3 1/2 size pin.? Nifty aye?
? The diamond nickel /chrome plated pins appear to have had the 
threads cut & then plated?over which I dislike & don't trust this 
though I ahve used them at one time.
? For my Shop made 1/4 cut maple blocks I've had the best uniform fit 
from the Diamond made pins.
? For years Trix miked all the pins in a set & put the largest in the 
bass & smallest in the trebles. Finding something truly round is 
about as consistent as finding something truly straight.? Just try 
running a micrometer on a few sets and on differing points on the pin 
& you'll see. It's a good thing wood is pliable & forgiving.
?? My friends once had a set of the Diamond that was oblong/out of 
round?but to my knowledge this was the only one we've ever heard of. 
This anomaly occurred during the time when we mic'd every pin... 
every set.? ughh.? SO diamonds are? more expensive but not when you 
consider we don't mic pins very often anymore?& they are as reliable 
as any we've tried
??
