On a few sets where the odd key could not be made square for levelling, I relocated the balance rail hole over. Sometimes the hole wasn't right from the start and they bent the pin. It's a good opportunity to correct factory errors. It is a bit pricey but it sure does the trick. Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
