tumbled center pins

[Roger Jolly]

Hi Don,
            If you are completely repinning the action, I would suggest the
following. Find some of the looser flanges. Ream the bushings and ensure
they are parallel. Determine the size of pin required.
Rough up a pin by rolling it on the bench under a medium file. Use this in
a pin vice for your reamer. the new pin should slide through both bushings
feeling equally snuggish from both sides. The next step I use a alcohol
lamp and a new pin in the vice, heat the pin and run it quickly through the
bushings. This irons the nap and gives very even friction. The result works
out perfectly consistent to the Yamaha flange screw test every time.
I think its about 4gms of friction?
Pianophile's  pins are Japenese, and I have found them to be very good.
I have ground down the sides of the tip of my wire cutters to form a flush
cut, it works better than my expensive centre pin cutters.
Do things in order e.g. remove all flange pins ream all bushings ect.
Hope this helps
Roger
