Tuning a Duo/Art player piano

There is usually, in console players anyway, a plate with instructions for the tuner mounted somewhere on the player mechanism or on the inside of one side of the piano.

I assume you are talking about the Aeolian Duo/Art console player, not the better stuff of long ago. If so, here is my procedure.

Unhook the chain from the air motor (note carefully how it is positioned before removing it), remove screw from the bracket that braces the air motor to the top of the back (?) of the piano, the frame that is. Carefully slide the large hose off the bottom metal tube below the air motor while tilting said air motor forward.

Remove the rearmost long screws from the trapwork bellows found, one each, mounted to the sides of the piano. Loosen the other screw in each, so you can swing these bellows down and out of the way.

Remove the screw and button holding the right side of the mandolin bar and whatever you have to loosen or remove on the bass end of it (not the cable) so that you can, carefully,  lift the treble end completely up onto the back of the piano, out of the way. Clamp it up there somehow. You may have to slightly flex it to get it out of the way but don't kink or bend it as it's aluminum and doesn't like to be messed with, if you get my drift..

It helps to tie two stick mutes together with string or a felt mute strip so that if one falls down into the guts of the piano, you can fish it out without undo cussing.

You'll have to work around the two brace-straps holding the roll mechanism in the middle. It's all kind of a pain and many techs charge extra, but you can do it, it's no biggie.

After carefully, professionally tuning with all of your skills and modern tools and techniques, the piano will sound lousy...don't be disappointed, this is normal.

Put it all back together in reverse order making sure that nothing (such as the mandolin bar) will interfere with the player mechanism--remembering that the air motor will have parts sliding back to front.

Cross fingers and toes, put in a roll (preferably a player test roll--Schaff sells 'em) and try it out. If you are unfamiliar with the player mechanism, don't be shy about having the owners assist you: after all, they've had much more experience at it than you have.
