I heard somewhere that it was better to cut the threads after the pin
had<br>
been blued for a better grip.<br>
<br>
Before you install new pins, deglaze the holes with a gun barrel
brush.<br>
I use a brush for a .30 caliber in a drill. Also mic all pins. It is
tedious<br>
but once you realize the discrepancies you will have motivation.<br>
What works best is a tension thickness gage which is a micrometer<br>
which is spring loaded. This will enable you to turn the pin while
it<br>
is being read. Discard the oval pins, they are there.<br>
<br>
For a 2/0 set I set up containers labeled: .279, .280, .281, .282,
.283<br>
and sort them. When stringing, the smaller diameters are for the
high<br>
treble and the larger for the low bass. A more consist ant feel
will be<br>
the result. This was on the list a few years back and has proven
itself<br>
worthwhile.<br>
<br>
Here's a thought to ponder: In the lowest bass, the core diameter
is<br>
the thickest. When 3 coils are made and the pin is driven in so the
coil<br>
is the same height off the plate as the treble, there is not as much
pin<br>
left in the hole. Granted it is small but with the tension it needs all
the help<br>
it can get. I generally make only 2 coils on the single bass notes or
use<br>
a longer pin to aid the longevity of the tuning. More often is the case
that<br>
the lowest bass is the first to develop loose pins.<br>
