[pianotech] Pitch change, etc.

[Scott Nelson]

Hi Ron,
 
Could you give us a little more information in regards to thickness, species ( I assume rock maple), and what specifically are the "bundles" to which you were referring? I tried navigating through the website and didn't see anything like you described.
 
Thanks,
 
Scott Nelson

That's it. You're making a fiber reinforced plastic. Hard, tough, stable, notch resistant. <G>

I get mine from Herzog. Their website http://www.veneeronline.com is flaky as it can be, but you can eventually find pictures of veneer bundles, 24 sheets to a bundle. I flip-flop and alternate 8 sheets (to get whatever minor cross grain angle I can), so I have three batches per order. Or just give them a call and describe what you want. They're real nice folks.
