Hello Pat, Yes I do. This type of grand action is a single escapement. Regulate it the same as a standard vertical action. That is the hammer shank on hammer rail with a tad of lost motion. Let off and blow distance the same. Thayer Action Co. built all of the " Staib " ( Grand ) actions. On the Foundation page in a recent Journal you will find a picture and a short commentary on this action. M. Schultz used this action also along with other Piano Company's. It worked well ( as a single escapement) action. Regards Jack Wyatt Dallas -------------- next part -------------- An HTML attachment was scrubbed...
