[pianotech] action brackets

[Paul T Williams]

I had to do this a couple times.  Both were existing customers of mine who 
purchased new from the dealer, and all "new piano" stuffs had been done.

It will take a bit of time.  I would plan on a short afternoon, or 
morning.  Once the brackets are in, you'll have to realign the jack to 
knuckles, set a new blow distance, backchecking let off drop, etc. 
Basically start from scratch on the stack.  If you've done this before, 
which I'm sure you have, being the keybedding is all good....key height, 
dip, etc. You'll  be fine in 3-4 hours or so.  Of course, when I did this, 
I would throw in a "touch up" tuning so it all sounds nice and also 
playable when you leave.  You might sell them on a complete cleaning too 
if you have the time...a way to pick up a few extra bucks while you're 
there. Good to do while everything is torn apart.

Best of luck
Paul

It depends on how much "damage" was done by the previous tech. If the 
action has never been altered, like the technician raising the capstans, 
or lowering the drop screws and let off buttons, then it will only take 
you an hour or so to install the new brackets, and make some minor 
adjustments. The man problem is with the middle two brackets. The holes 
for the new ones are not in the same place as the old one. So you'll have 
to drill new holes, at an angle, to fit the holes in the bracket. The 
problem with that, I've found, is that the screws that hold the wood 
braces for the action brackets, will be in the way, so you'll have to move 
them first. I sounds more complicated than it really is. 
 
While you've got the action on the bench, it's a good time to remove the 
keys and clean under them. You can also shape the hammers and tighten the 
screws. But other than than the job of replacing the brackets is pretty 
straight forward. 
 
What you want to watch for is the position of the jack under the knuckle. 
You're told, and others will tell you, that you have to have the exact 
action spread. But I've found that lining up the jacks under the knuckle 
core will get the job done, too. Do the end ones first, and the replace 
the middle brackets.

I am about to get a job replacing Young Chang grand action brackets.  How 
many hours can I expect this gig to take?  I did a few Marshall and 
Wendells many years ago, and they took a ton of regulating.
