[pianotech] Pitch change, etc.

Thanks Ron for the referral, and others who have commented.  What are you
using for an epoxy, and how much do you thin it to get the saturation?

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.
