[pianotech] Pumper Flap Valve Leather

[John Ross]

I will try that on a sample piece. 
Fast moving being the operative word, as the heat would normally make it hard.

  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.
