Leveling a Harp
« on: December 11, 2018, 05:52:46 PM »
Hey all,

Long time reader/hobby refurb guy.

I'm working with some 1969 Wurlitzer student models and the harps have not been shimmed and I'm trying to get the harp  un-tweaked. Any tips from you pro guys on how best to shim the harp and maximize ring time across the piano?

So true, but at least I can get notes up to pretty good sustain. All but one or two on each harp.

Just remember the shims need to be insulators since the harp has voltage in it. Rubber, plastic, etc. not metal

I've been using balance rail/ front rail shims for it. Its what I had seen in the 5 other pianos I had refurbed so I figured it would be good.

I’ve done that too in the past. Rubber washers are good too.
