Greg, If you are using a good quality lacquer thinner, it may be contaminated or has a high water content. There is definitely something in your lacquer thinner kicking out the nitrocellulose. Find yourself a good quality lacquer thinner or use MEK or Acetone. I prefer MEK to acetone because it's slower and has more time to penetrate deep into the hammer, but lacquer thinner is best to use in the shop or when you have time for it to dry. Al Guecia From: Greg Graham Sent: Monday, June 02, 2008 12:09 AM To: pianotech Subject: hammer lacquer clumping I have some lacquer for hammer voicing (from Steinway) which, after dilution, forms a clump in the bottle, looking something like a Lava Lamp. I'm using standard "Lacquer Thinner". If I shake the bottle for a loooong time, the clump gets smaller, but never really goes away. I've never experienced lacquer that wouldn't stay dissolved.
