Propping up side-hinged lid

[Paul McCloud]

Hi, Paul:
    I don't know about that exact model, but Yamaha has a special type of hinge pin on some of their pianos.  If you turn it in the hinge (not remove it), the hinge will come apart.  There are flats ground into the hinge pin that allow this to happen.  Lift the lid on the hinge side while you turn the hinge pin- you'll find the lid will detach at a certain point.  Of course, if this model doesn't have that kind of hinge pin, you'll have to move the piano away from the wall and remove the pin.  I doubt that you'll have to unscrew the hinges.  But then, what do I know.  Someone else on this list will confirm or deny this.

Hi all

This is my first post to the list...

I have a question about techniques for propping open the lid of a piano with a side hinged lid. I tuned a Yamaha M1A the other day and couldn't figure out a good way to get the lid open high enough so that I could get my tuning hammer on the pins vertically. I tried flipping the lid all the way open but it hit the ceiling. And short of unscrewing the hinge from the lid of case I couldn't come up with anything.

Any suggestions?

Thanks,
