This is the first time I have heard of grit side to the pin. If I do it now,because, I don't have an oversize pin, I will= frequently use a bit of veneer. One thing NOT to do is use these metal tuning pin bushings, that= are sold by the supply houses. I still have them left from 1975,= when I didn't know better, and bought some. Regards, John M.

Also, if the situation is bad enough, a piece of 150= grit sandpaper could be cut in about a 3/8" wide strip, the= length of which would be twice the circumference of the pin,= folded in half width wise and wrapped around the pin and put= back in the hole. The folding in half width wise, allows you= would wrap the grit towards the outside of the pin and there= will be grit surface towards the inside of the pin, so that the= grip occurs between the pin and the block's hole and the pin and= the inside of the sandpaper. I never had to try it yet as I have only been tuning= for a little over a year. It worked at school and I would try it= if I had the need. Hope this helps.
