Tom, 

If it's THAT toxic (yeah right!) most of us are on our way to the cemetery,

Brian,

If you heat Teflon beyond a certain point, it starts to out gas some toxic
stuff. I don't think hot feet is going to be a problem, though. go to

Yes. And quite possibly extremely toxic, and conducive

to cancer and horrible, horrible birth defects. Bad

idea.

Hi Alan:

    Did you determine if the wippen flange was

stuck?  It often causes the

key not to return quickly.  Unfortunately, if this

is the case, you won't be

able to determine this unless you take out the

action and check it.  I vote

for the iffy weights.  Good luck.

First visit, new customer, Baldwin Howard spinet.

 

Customer complains that F2 "sticks". Sure enough, it

is very slow to return.

Lift sticker off the key end and the action seems

lively enough. No problem

with keyslip. Look at back of key and, guess what,

someone else tried to fix

this key: It had a jiffy lead nailed to the back.

 

I removed the lead, so I could make a propper

repair, for heaven's sake! I

eased the key a bit and then it would return just as

fast as its neighbors.

Done ... or so I thought.

 

Tuned and was playing the piano when I noticed F2

"sticking". Further

experiments revealed that it only happened when I

depressed the sustain

pedal. Hmmmm....

 

Tried holding the damper off the string with a hook

(no pedal pressed) and

the slow return was still evident. Hmmmmm....

 

I could not, offhand, think how the damper, damper

arm or spring, would

affect key return like this. I was out of time,

running late actually, so I

had to come up with something quick.

 

Simple. I nailed the jiffy lead back in place. Works

great.

 

All I can think is that maybe the felt is worn and

the spoon is snagging on

it, or something. And I do want to fix it properly

next time.

 

Any ideas, oh wise and knowing List?
