[pianotech] Replacing plastic elbows

I agree with Wim.  Trying to find a replacement piano for $500 that was well
taken care of and needs very little to no work is very difficult if not
impossible.  Many years ago, I used to replace them with the snap on ones
too finding that years later if not sooner, the new ones also broke.
Replacing with wooden is the best way.  No more broken parts 15 or 30 years
later. Just make sure the dampers and hammer flanges and other parts are not
also plastic as well.

You're probably not going to like what I'm about to suggest, because it's a
little more work, and goes everything else you've read. Vagias snap on
elbows are good for replacing a couple of elbows in the piano. But if you're
going to do a whole set, and you've got the action out of the piano anyway,
why not replace them with wood elbows. My arguments is, plastic was used
once, so why replace it with plastic. (I know, the new plastic won't
disintegrate like the new Vagias ones. But that's my story, and I'm sticking
to it.) 

Lay the action on the bench, dampers down, and remove the center pins from
the wippens. It's not that difficult to do, once you get the hang of it. The
old elbows, or what's left of them, will fall right off. Before putting on
the new elbows, tighten all the screws, shape the hammers and blow out the
dust and dirt. 

An easy way to put the new elbows on the sticker is to chuck the sticker
into a variable speed drill at the regulating button end. (Sometimes you've
got to screw down the regulating button a little to get enough into the
chuck). Put the elbow in a vice, and drill the sticker onto the new elbow.
Try to get the sticker about the same distance into each sticker, but don't
try to figure out which sticker goes to which wippen, because you're going
to have to regulate all of them anyway. Putting the stickers and new elbows
on the wippens is also a little tricky, but again, once you've done a couple
and get the hang of it, it's actually very easy. If you're careful, and
don't break any wippens, it only takes about 2 hours to do the whole job. 

 

Before replacing the action, you probably had to take the keys out. So
vacuum under the keys, and down in the bottom of the piano, to get rid of
all the plastic remnants of the elbows 

 

I haven't done a set for at least 10 years, but over the years, I've made a
lot of money from Betsy and her cousins. The total job, including replacing
the elbow, vacuuming, regulating, tightening the screws, etc. is worth at
least $500, plus tuning. As much as some people seem to belittle Betsy and
her cousins, some of those pianos weren't all that bad. If the case is still
in good shape, it would be well worth the money to spend on replacing the
elbows, as opposed to buying a new piano, or a decent used one.

Dear Friends,

I have a Lester spinet action belonging to a long-time customer on my bench
(that is, my dining room table) that needs new elbows.  I thought replacing
the original plastic elbows would be easy, but only the broken ones are
brittle; the unbroken ones are hard as concrete.  How do you replace these?
Unpin them to put the new ones on? I don't want to risk breaking the wippen
by trying to bend the old plastic ones. I'd be grateful for your advice, and
my wife will be thrilled to get the dining room table back.
Thanks,
Greg Livingston
PS- I have not figured out how to search the archives, though I've tried; I
need help in that area, too.
