Unusual fall hinge hardware - A Tuesday Tech Tip

    Recently, a fellow tech called up and said, "Allan! Help! I've been sitting here for quite a while trying to figure out how to get the fall out of this grand so I an access the action for a simple repair. It doesn't have regular hinges on the inside of the rim, in the fall, or in the cheekblocks." After thinking for a moment, I suggested that he check for something fairly rare and tilt the fall out 45° to look at the end of the fall. Once he did, he saw something similar to what you see in the picture below. By removing 2 screws on each end, the dado in the end of the fall slides off the hinge rails (which have one screw holding the hinge rail to the inside of the rim and inaccessible until the fall is removed) and the fall can be removed.

    Replacing simply involves lining up the dadoes with the hinge rail and sliding the fall into place until the screws holes align and reinstall the screws.

    You don't see these every day but file it away for that odd when you do see one of these. ( I saw this one last week on a Weber grand.)

    And, I tighten the screws into the case to aid putting the key cover back on.

    LOL. I remember the time I encountered one of these. (I've only seen the one.) How the devil am I going to get INTO this thing??

    I eventually spotted the screw heads but it was at least a quarter hour after arrival.

    The other tricky Chinese puzzle box is an upright with no lid hinges or visible fasteners. Screw heads are captured in kind of lock plates on the under side of the lid. The magic is to slide the lid firmly toward the back (if I remember right -- I think it was toward the back instead of pulling toward the front.) Then the screws line up with wider openings and the lid can be lifted off.

    Had an old Steinway XR recently with that fallboard hinge.

    The biggest puzzler I ever saw was an institutional Wurlitzer vertical, about 44 inches tall, made in the late 1960s.  There were no screws visible anywhere, and the front wouldn't budge.  I finally located a pair of long (over 12") bolts running up through the sides from below.  Presumably this was done to keep school kids from getting inside.  I've never seen a second one.

    And then there are the Story & Clark studio verticals that have L brackets instead of hinges on the top lid. Oh, and they're attached with Allen nuts instead of screws. Once you get the Allen nuts out you have to slide the whole assembly back by an inch to get clear of the  blind screw and bracket catch holding down the front.

    And then there are those “techs” who are positive those “L” brackets must be some kind of fancy hinge (usually found on Everette consoles) and pry the top up anyway.

    In a pinch, a large flat blade can usually loosen the Allen bolt, but no, couldn’t try that; couldn’t diagnose the problem ; had to assume they were right.

    Thank goodness for these forums and tech tips in the Journal. Why doesn’t everyone see the benefit of participating in PTG?

    Speaking of Wurlitzers, with every cabinet style under the sun, a friend was unable to open the bottom of the console to change a string. There was no bottom board clip or knob to pull forward, no screws at all anywhere. I looked under the keys for a long screw that would hold the bottom board. Nope. It was one of those cabinets where there are panels on either side which are permanent, with a smaller panel in the middle that is removed for service. The left and right panels had a gap at the top, so I wasn't sure if they came off, but I didn't know. Looking and looking, prying with a bar, it looked like it moved, but there wasn't enough room to lift it out. It had a sort of vertical wooden grill, and speaker cloth behind it. Frustrated, I yanked on the grille. It moved. A-HA! I pulled hard, and the grille came out. It was held with clips, like the ones used on cabinet doors.

    I think I've also seen one of these Wurlitzers. It took quite a while to figure out what was holding it together. 

    Confession time also...in my frustration, I started trying to force things apart, thinking maybe something was stuck. A small crack, ahem, er...somehow "just happened" right where the bolts were. After that, I could see what held it together. It wasn't a bad crack, and wasn't even visible without any pressure on the panel. Anyway, they never had me back, but that's ok. I really doubt it was because of the crack. I really think it's because it's at a church that only has the piano tuned every 10-15 years.

    I hear you, John.

    The default position for piano techs is to want to schedule regular service, but for a lot of pianos, I think that I don't want to see them more often than every 10 or 15 years. For a few instruments I can remember, the right schedule for servicing (at least by me) is every 30 years ...

    Hi Allan,
    I'll have to remember that "fellow tech" line (wink wink). A good thing about that design is,  it only fools ya the first time. Many custom art case pianos can have tricky set ups, hidden screws etc. Keeps ya on your toes.

    While we're on this topic. Cheek blocks on a grand screwed into the side with screws reached from under the keys after the key slip is removed.

    Hi Allen

    I have a new customer whose piano has that same fallboard hardware, but the part that attaches to the case at each end is missing. I need to come up with a way to re-attach it, but do not know what the missing parts look like. Any chance you have a picture of that?

    Thanks

    Good morning Craig,

    I happened to be close to the client with the Weber grand and she was gracious enough to let me stop by and grab a quick picture for you.
