re-stringing and CA

I've done a couple of uprights this way with excellent results. I just
squirted a little CA directly into the hole before driving in the next
size larger pin. I use an air chisel to push the pins in instead of
driving them with the hammer. It has to be easier on the pin block.

Larger pins (lo-torque or otherwise) have to put more splitting pressure
on the pinblock, possibly causing further damage.  Using same-size
replacement pins and pre-treating the holes with CA might fill in some
existing cracks and make the block stronger.  Would you swab the holes
first and let it dry before driving in (or dropping in!) the pins, or do
it in one go?
 
Just guessing, here...

Hello John and List
The old pins are grotty, rusted and deformed and would not be worth
preserving and re-bluing. Apart from which the old pins will have their
scoring (the end part of the pin which is in the plank) filled with old
wood particles and rust. The new pins will be chromed and indeed .. new.
The object is to find out what your collective reaction is to CA-ing in
new pins.
