Hammer butt leather

Do you hear a pronounced scratching when you play your keys?

Your butts may be losing their leather.

Looking at these two images you will likely see the problem.  It is relatively simple to resolve the loose leather, but be careful.  Don't use so much glue that it soaks into the leather causing another "noise" problem once the glue had dried.

I like to use a 60 second curing super glue.

60-90 Second Cure "Gorilla" brand

After applying the glue, press firmly and hold in place until the glue sets.  Alternately you can hold tight with a clamp, rubber band, etc.

 Re-install part and your jacks won't be dragging along your butt leather improperly anymore!

Listen to the video, pay attention to the sound when the parts drop back to rest position.

If you were able to look inside you would likely see this:

See the whitish area that is circled?  This is glue residue which is causing the noise.  Take a flat bladed screw driver and pull it across this glue to scrape it off the red felt called a hammer butt square.  Now test the note. If you have removed the glue residue the noise will be gone, no more "click".

Be careful not to dislodge the felt otherwise you will need to remove the action and find the felt that has come off and re-glue.
