What do others do when the felt strip for the middle pedal on an upright starts to wear out? This is a Yamaha M450.

Either get rid of the felt, or replace it.

You can buy felt strips for this purpose, and its also available as a sheet, graduating in thickness. The UK supply houses call it 'celeste felt', nut sure if it might be called muffler felt in usa.

You can buy replacement felt from Yamaha in California, I believe.

There is a phone number here, but they have online parts functions as well.

Thanks! I found some tapered muffler felt at Schaff and I’ll contact Yamaha to find out about the actual part.

It can actually be quite a fiddly job to fit new muffler felt accurately. It may take longer than you think, to remove the old felt cleanly, and fit the new stuff carefully, so that it engages to the correct depth, yet fully clears the strings when not engaged.

Some years ago I fitted new muffler felt to a little Yamaha upright, and the coil spring that lift the rail pinged out of my careless grasp, I know not quite how, and disappeared. I spent a fruitless half hour grovelling on hands and knees searching under furniture for it, without success. I think it vanished through a warp in the space-time continuum. In the end, since I had a string coiler in my case, I made a new spring out of 20 gauge piano wire, which looked pretty good and worked perfectly well.

The information on the Yamaha muffler parts is below.
Maybe M450 is T802000. U1E,F,G type.3 part with under felt.

Newer Yamaha uprights have a rail that comes off by loosening the screw near the spring end, so you do not need to fiddle with the spring. Thank you, Yamaha!

In some cases it may be possible to get more mileage out of the felt by adjusting the rail a little bit further down.

Yes indeed. Much easier.
