CAUT

Lists,

We have a Yamaha C7 from which we are currently unable to remove any of the lid hinge pins. We have had the lid off this piano several times over many years. Can't get any of the three pins to budge, even with someone raising and lowering the lid while pliers are on the hinge pin, being struck by a rubber mallet.

As you might imagine, we are curious about what may have caused this condition. And knowing the cause may steer us in the right direction about how to remedy it.

But regardless of whether or not we figure out the cause, we have to fix it. What is the best brass to brass lubricant? 

Also, we have considered trying to drive the pins out with a drift, made of either brass or something softer. Anyone with experience doing this care to weigh in?

Thanks,

Alan

Fred,

Ditto my response to Wim about matriculating to a hammer.

If a hammer doesn't work, I will try a nail set to get it moving. If at that point it still can't be pulled out, perhaps grind the pointy end of the nail set down so it can reach further into the hinge.
