Front lid extended during performance

I wouldn't bother referring them to anyone. Hinges are simply not designed
to support a load in that position. Not even piano hinges. If they insist
they have to always have it open in that configuration, you or a carpenter
should design a proper means of stiffening the joint so as to relieve the
stresses from the hinge. If they (the owner(s)) disagree, then challenge
them to prop the lid open the way they like it and hang/pull on the closed
front. Be sure to be standing a ways back so they don't fall into you when
the hinge/screws fail(s). (I'm kidding... don't even suggest that because
some people will do it... and then make you fix it... and charge you for the
hospital bill.)

Think about it. Would you remove the stop from your bathroom door and then
move the door beyond its closed position? No. That kind of leverage would
rip the screws right out. Ever noticed how a hydraulic storm door closer
typically has a safety chain/spring to prevent the door from leveraging its
bracket out when you open the door all the way?
