HI Tim,

Replacing Baldwin Abstract Grommets
Replacing hardened and/or crumbling grommets on metal Baldwin spinet abstracts is really easy and this method require minimal regulation.
•    With the action still in the piano, use a hook to pull the lower hook of the abstract from the fork in the wippen.
•    Remove the abstract, with the grommet in place, from the fork in the keytail.
•    Slide the bushing loop off the hook then slide the old bushing off. 
•    Slide on a new bushing on the abstract then slide the bushing loop back onto the hook. 
•    Place the abstract grommet back into the fork in the keytail. 
•    Push the bottom hook of the abstract back into the wippen with the glued portion of the loop facing out.
•    Repeat 87 more times.
•    Vacuum up the mess from the old crumbled grommets.
•    Adjust lost motion via the nylon nuts on top. 
•    Elapsed time: approximately 2 hours. 
•    Do any other work and bill for your time and parts. 
•    Notes:

• Don't spin the nylon nuts off, especially with a cordless drill/driver since this loosens the threads and introduces regulation stability issues. 
• I sit in the floor on a kneeling pad to do most of this work.
