[pianotech] Pumper Flap Valve Leather

[Greg Newell]

John,

                Could you burn the “hairs” away? A heat gun or a fast moving
propane torch should do the trick I’d think. It’s kind of what you do when
you’re looking for a good, clean looking edge after ripping felt.

I purchased some bulk flap valve leather. 

Previously, I had used the precut individual ones.

This leather has courser hairs, or whatever the strandy stuff is.

I was thinking that this wouldn't be as air tight, so I was thinking on
putting it hairy side up, on a flat surface and sanding it.

Would this work, or should I just go back to ordering individual ones from
Schaff? 

Or just cut it to size and use as is?

I can't even remember where I got it, probably APSCO.

I suppose I could just use the original inside ones, as they seem fine. 

That way if the outside ones didn't work, I could just change them, without
having to recover the bellows?

Any suggestions most welcome.

Thank you.
