Pressure bar on upright piano

[Elian Degen J.]

Thank you very much Richard

First thing I did before asking was to tighten (without rising the pitch)
turning all screws until I felt they  were tight enough without pressing to
hard on the strings, then I tried pitch rising several notes after sliding
the strings in their place, and this time they did not slip, I did not want
to finish the tuning until having an answer, I thought maybe there was
something more to it. but that is a simple rule to remember
