opinions on this CA job for loose tuning pins

[carlteplitski]

About a year ago I stated that a tuner on the list , ( can't remember 
his name )  had a great sense of humor.
Well reading this message this AM had me giggling so much my wife came 
into my office to see who I had
in here with me.  Other times she comes in here just to make sure I 
haven't expired , because I can be quiet, too. 
If you have worked at all with C/A you will know that those remarks, ( 
glue your butt to the bench ) aren't that
far stretched from reality.  Sure enjoy this list. Need the great info., 
and the humor is good for your heart, I hope.

It's reminiscent of the days of inserting sandpaper suppositories into the pin holes (wasn't THAT a pain in the ... oops, never mind.) If you already have the pins out for a restring or whatever, then larger pins seem appropriate. If you have to take the pins out, why do that just to get the goo in there???
