    I spent a while trying to figure out how to remove the cheek blocks on a Haines Brothers 6 leg grand.

    I finally found the screws in an unusual place: under the top of #1 & #88.​​

    There was also an interesting action "handle".

    Hi Blaine:
    Interesting the ways the blocks are held in place. Some are very thin, so it makes sense to screw them in sideways. A screw from beneath the keybed might not hold it straight or keep it away from key 88.
    I had to remove the fallboard from a very unusual spinet the other day. It had metal strips embedded in grooves on the ends of the fallboard. I scratched my head for a moment, and then remembered I'd heard about these some time ago. Sure enough, a couple very small screws held it in place. Pianos are very much like giant Chinese puzzles. If you don't know the secret, you might have a problem opening them. Wurlitzer especially had a huge assortment of cabinet styles and secret ways of getting them apart. One I remember was the bottom board, which was more like a grille. There were no screws anywhere! Finally, I just yanked it outta there. It had those cabinet door hardware clips on it. Duh!
    But if everything was made the same way, it might make our work less challenging and more boring.

    My family's old Chickering spinet was one of the more difficult pianos to disassemble and another similar Chickering stumped me even though it was the same style.
    I have seen a LOT of pianos and still run into a tough one about once a month.

    Never found one I couldn't open (OK, that orchestron was a real mystery; it was apparently glued into the case).

    Hello Blaine,
    It looks that the Handle was retrofitted to pull the action out?
    I like that idea since I have broken a few hammers pulling out actions...

    This was apparently either an ex-player or a player model without the player mechanism, as there were player holes under the key tails and key felts for the mechanism but not the usual plethora of screw holes.

    Hi Blaine.  Thanks for sharing.  AS for the holes under the backs of the keys  .....  talk about labor intensive!!  I suppose that was to accomplish the somewhat critical alignment for each push rod.  And then to have to punch the hole in the backrail felt for each actuator!! 

    I couldn't quite put together in my mind how the cut out in the key frame acted as a handle.  It looks like it was cut out after the fact using a coping saw.  I've seen the little embedded metal handle located in the front of the key frame on some olde grands. 

    The player was obviously hung under the keybed using a minimum of screws passing through a super-structure of some sort.  Can you imagine trying to put that thing back up there getting all those actuators back in their little holes? 

    I've used a motorcycle lift from Harbor Freight to drop a wheelhouse pump out of a grand to replace some brittle wiring.  That also comes in handy to drop and re-install the current PianoDisc player mechanism.  I'd imagine something of that nature would be needed to put this 1920's version player system back in this grand.  To work on the action you'd have to drop the player mech!!  Ufda MEG dare once hey.  YAH, no wonder it's not under dare anymore.

    I once worked on an older grand that took me some time to figure out the cheek block screws-turned out they were one of the leg screws! I don't remember the piano maker, the piano itself was from the 1920s or 1930s.  Egads, a 1920 made piano is now over 100 years old-how did that happen???
    My 1932 Marshall & Wendell Ampico grand action also has two formed wire handles for pulling it out-I assume because the cheek block area is so small one cannot easily "grab" the action frame there. Very convenient, especially when adjusting the note striker rods from the player stack. See attached picture showing one of the handles-also note the stepped balance rail pins. Another oddity, but they seem to be in good condition!

    Just yesterday I had an older Lester grand where one leg screw was up through the key bed and into the action.  Removing the action required removing the screw (fortunately it had leg plates).  I will have to saw off the end of that screw on my next visit.

    Is it possible the tail leg uses longer screws?

    I have encountered this problem more than once when movers just screw stuff in. 

    Just sayin'

    (Also common when lost screws "replaced")

    While this may be the case (wrong screws), both leg screws were protruding into the action cavity.

    The piano I mentioned  using one leg screw on each side to hold the cheek blocks in place was manufactured with that feature. I must have spent a half hour figuring out how to get the action out. I've forgotten why I need to pull it, but something was wrong that need the action out to correct the problem--this was about 20 years ago, I forget!!
