G'day Fritz, I would be very cautious about WD40. I know you went to some lengths to ensure the tuning pins were unaffected, but the bass string windings can also be severely affected! I've heard many a dead bass resulting from WD40. As I've mentioned before on the list, I recommend the use of a drop in pitch on each string before you pull it up and over pitch. It only takes a little practice to become comfortable with the quick flick down .... then up as usual. Don't be too nervous about pulling pianos up to pitch. They are designed to be there...it's a matter of convincing it (the piano) to be comfortable at pitch. If you check the pianotech archives (via the PTG Piano Page) there's quite alot of discussion on pitch raising that could be helpful to you.
