Dick, I do use veneers quite often, some I grind myself and others I purchase. You can get some beautiful stuff from, believe it or not, eBay. I grind my veneers to about .0025". The commercial veneer is usually in the .0020" - .0023" range. I cut it with a sharp razor knife to the width and length that is needed, right before I glue the bow up since it will sometimes want to curl and cup on you if you let it sit around for a day or so. Naturally since it is so thin it is also usually very dry and alot of care is needed to work with it.

May you be forever blessed with favorable winds and clear trails.
