changing hammer line

[Lance Lafargue]

List,
I am replacing hammers, shanks and flanges, on a concert grand soon and the
hammer line in the treble section may have been tampered with.  So, before
hanging, I need to find or confirm optimum strike location (particularly in
the lower treble section). What is the _best_ way to go about this?  How
does everyone secure the hammers temporarily (strips of paper? tack glue?),
listen, move around, etc before permanently gluing end hammers?  Thanks,
