---------------------- multipart/alternative attachment Ola, Paul, and Stephen The Bluthner specs also say that the hammers on the Patent Action rest on the rail. If the blow is correct and the hammers are off the rail - then the rail covering needs attention. I use the method that Stephen described. I also agree with Stephen's comment above using the corect type of 'felt' for this. Uri gella aside! I have not found the 'L' shaped spring that easy to regulate. I don't see how this spring can govern hammer height AND drop effectively? Regards Rob Thornton ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
