[pianotech] Wurlitzer console action bracket hold-down screw

[Dean May]

I use a concrete anchor bolt/nut when I have trouble with these Wurly spinet
action bolts. There is a concrete anchor nut that is made of lead, designed
to fit into a hole in the concrete, then as the screw is tightend, it
swedges the lead against the hole forcing a very tight fit. One of the sizes
available is a near perfect fit for the hole in the plate of these Wurly's.
The anchor looks like this: http://www.boltdepot.com/product.aspx?cc=35
<http://www.boltdepot.com/product.aspx?cc=35&cs=149&cm=89> &cs=149&cm=89 
 
First time I ran accross this problem I was a newbie working in a music
store and I was eager to "prove" myself. I went to the local hardware and
explained my problem. The ole boy there helped me come up with this
solution.

David,

I've done enough with "normal" bolts to know exactly what you're talking
about! (That was my comment about old uprights in my first reply to Frank.)
I don't know that I've ever sent a damper head flying, exactly, but I have
nudged some out of whack. Fortunately, the resulting utterances have always
stayed inside my head instead of escaping my lips.

I've attached a couple photos, worth so many words. The first shows
plenty(?) clearance at note 1. The second shows the current screws unscrewed
far enough, and the action tipped back to where the brackets would clear
"normal" bolts. It certainly looks to me as though it would easily clear
with a modicum of care without cursing the noob (moi) who replaced the
screws. 

Additional thoughts?

Paul,
 
It is about not clobbering the dampers on the way out or back in. There are
some spinets with bolts on all but the bass/tenor break. That is the most
common place for a damper head to go flying. Do a few more of the ones with
"normal" bolts, and you too will curse the gods of piano design. (Present
company obviously exempted, Frank!)
