Ted Simmons Whatšs the latest on whether or not a pinblock should butt against the p= late flange?  I have a customer who has a rebuilt piano that wonšt hold= tune for even a day and when I removed the action and checked the pinblock-= to-plate fit I found gaps throughout, some as much as 1/8 inch.  Two we= eks after I tuned it I found it over 20 cents flat and had to give it a pitc= h raise.  A few weeks later it was overly flat again and in need of a p= itch raise.  I explained to the customer about the pinblock to plate fl= ange fit but he said that he was told by the rebuilder that such a thing was= not important.  To top it off he did some research and got conflicting= comments.  Some said the piano is OK as is while others held to the co= nviction that the gaps in the pinblock are the problem with his piano. &nbsp= ;I need some backup in my assessment, either pro or con.
