<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top" style="font: inherit;"><div>I would see this as a chance to upgrade the original construction. By adding some hardwood laminate to the back structure and/or, perhaps even better, bolting a large pice of angle steel (high-carbon spring steel grade, to resist bending) to the back of the piano and across the top of the block (routing out a bit if needed, so the lid still closes.) I'm, doing this on a big, art-case upright now, using a piece of 5" leg steel angle, 1/4" thick and about 5' long. The big upper plate lags will be replaced with bolts that go through it.<br /><br />Thumpe</div></td></tr></table> <div id="_origMsg_">

It's on Mini Piano named Gerard, and one can follow the progress here: <br><br><a rel="nofollow" target="_blank" href="https://www.facebook.com/media/set/?set=a.414081118675357.98495.146765508740254&type=1">https://www.facebook.com/media/set/?set=a.414081118675357.98495.146765508740254&type=1</a><br>
<br></div>The pinblock severely pulled away from the posts. It is a 3/4 plate, and there are large gaps behind the pinblock with no support. That's my current concern. I had epoxied and bolted the pinblock a few years ago, and it held for a couple years. My plan is to reread Chuck's Replacing the Pinblock series which was published a couple years ago in the Journal (and which I read at the time) and follow those steps. However, I believe<img alt="Inline image 1" src="cid:1.2266348021@web142606.mail.bf1.yahoo.com"> I will need to add supports, fill in those gaps between the posts. <br>
<br></div>Any glaring issues or recommendations from you experienced rebuilders before I start?<br><br></div>Thanks!<br><br><br></div>
