Great tip because I have 20 to go!
But, 10 seconds in Kleeer Acetone and the flew right off to bare wood with a large flat blade screwdriver.  But I did note that mine had really gotten stiff over the years.  The looked untouched, but tough nonetheless.

Just to be clear, steaming will only work if the adhesive is water-based.  Just like adhesive that doesn't respond to acetone will respond to steam, adhesive that responds to acetone will not respond to steam.  So, it's one or the other.

Hi everybody,

On my 77's rhodes piano I have flat pedestals. I don't know if I've to place bumps and new red felts from the Miracle Mod on pedestals and removing the originals felts on hammers (white felts on hammer cams), or if I've to leave these original felts and just put bumps on each key pedestal...

Thanks in advance !
Bill

Either way would work, though I think most people decide to take the felt off the hammers and put the bump and felt on the pedestal.  I believe that was the factory solution to the sluggish action on the 76-77 pianos.

I understand, thanks !

I made this modification on some pedestals, but when I place hammers on the rail to test the ideal position for the bump (and also on some keys that have their modification complete), I hear a "click" that seems to come from the damper arm bumping against the hammer... I don't know if it's normal, but I don't think so...

After this is installed, should I put some sort of teflon powder or other dry lubricant between the felt and plastic?

The consensus seems to be do NOT put Teflon powder in the pedestals.  Over time it builds up in the felt and  apparently acts as an abrasive on the back of the hammer cam, which causes wear, and in the end an even more sluggish action.
