[pianotech] Installing Vertical Piano Hammer Return Springs

[John Ross]

Initially, I just used a piece of coat hanger. Then I got more 
sophisticated, and bought a piece of bronze rod or something from a welding 
supply place.
Just run it through the coils, and it keeps them lined up.
remove the old ones carefully, as they sometimes break, and it is harder to 
get them out.
Clean out the grooves, and just fold them over into the grooves, pushing 
down with a small screwdriver.
Use hide glue along the surface after bending into the groove, and put on 
your piece of felt.

You can also use a drill bit of an appropriate size to fit inside the coil
and advance it along as you install the springs. I recently did just that.
