---------------------- multipart/alternative attachment You're right, it was a disorganized post. I'm a mich. tech. new to this block, was craftsman rated back in 1972. Consider this, if you had an EIGHT foot Starrett straightedge, (machine builders use these for .001 precision) where would you place it over the board to do measurements ? Right over the long axis of the long bridge ? Would three placements in a triangle give a complete enough picture ? Most precise bearing gauges use a bubble level to establish that perfect plane in space, would a straightedge be as good ? I tooled up a little sled with a dial gauge to ride the straightedge, but how to develop the total picture from the raw data ? By the way I thought surely a cool name like crashvalve would be already taken, but nobody was as odd as me. I enjoy this forum immensly, the information is post-graduate level and i'm learning. My weak point is communication (ask my tuning customers) but I am good at machining, and recommend learning same to any piano technician, if you want your dream tool you can just run it up. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
