<div dir="ltr"><div><div><div><div><div>Thanks all. I have read the 1'st two of Jack Krefting's Upright Restoration articles from 1982 and ya'll echoed some of those ideas (steel, or plywood, reinforcement; fixing tuning pin position). <br>
<br></div>Mike: it is not a 2-part block. So no problems there. <br><br></div>Flange-mentioners: i don't think there is a flange. as a matter of fact, the plate is sitting on top of the lower pinblock. No wonder it failed. You can like reach your fingers underneath the plate, like, all over the place. (well, not ALL over - but most of it, as it rests a half-inch or so from the soundboard). <br>
<br></div>Plus, I'm not sure the pinblock was made of the best wood. <br><br></div>Not to worry! We'll figure it out :)<br><br></div>I don't expect any replies here until I get into the shop again and learn more and get some pinblock-specific pictures. Just responding to the posts. However, i'll attach a photo of the back. <img alt="Inline image 1" src="cid:ii_13ca19fe07a1c7d6" height="316" width="474"><br>

I agree with everything Chuck has said. In addition:<br>
<br>
Most likely the new pinblock will need to be fitted to the plate
flange. Do this exactly as you would for a grand piano; i.e.
jigsaw as close as you can to original pinblock shape, refine with
chalk transfer from plate flange, finish with epoxy (West with
colloidal silica filler, not the stringy yellow goop in your
photos)..<br>
<br>
I can't tell from your photos whether your original pinblock is
one piece, or split at the tenor block (see attached photos). Do
not split your replacement. The pinblock will be the main
structural member across the top of the piano, don't do anything
to weaken it. Further, I'd recommend that you choose your
pinblock material for structural rigidity rather than your
preferred tuning pin feel. Delignit or Falconwood.<br>
<br>
good luck<span class="HOEnZb"><font color="#888888"><br>

<blockquote type="cite">Hey, Noah - Sounds like an interesting project you're
embarking on! I'm assuming this piano has a lot of sentimental
value to you or someone near and dear (hence it goes by a name),
because you'll be spending a lot of time on this. Well, if nothing
else, it'll be a learning experience. <br>
<br>
The article you're referring to deals with quite a bit different
situation - a solid pinblock which simply needed the pin fields
routered out for the insertion of pinblock panels. By the looks of
things, you're beyond that repair scenario, and will be looking at
a total replacement of the pinblock, complicated by the excessive
goop which will need to be completely removed from the back
bracing before replacement may commence. <br>
<br>
Before tackling the removal of the old pinblock, however, the
first order of business is establishing the correct placement of
the pins before their positioning is lost. You'll need to make a
paper pattern, using contractor's or butcher paper (not several
sheets of computer paper taped together!). Remove the old pins
(noting the angle at which they're drilled) and cover the entire
pinblock with your paper. Crease the paper along the sides and
clearly mark the position with tack marks for later positioning.
Use a pencil to make a rubbing of the tuning pin holes. For photos
of the technique, have a look at the <a href="http://www.pianopromoproductions.com/resources/34.%20Mar.%2C%202011%20Small%20Shop.pdf" target="_blank">March,
2011 segment of the "Small Shop" series</a>.<br>
<br>
The juncture between the bottom of the pinblock and the rest of
the piano hopefully is not complicated. I haven't taken one of
these particular pianos apart so I'm not sure what you'll be
looking at. Anyone else have a clue?<br>
<br>
Best of luck. Chuck<br>
