Janssen info needed.

[Richard Moody]

I recently tuned a Janssen console 116331 (1952) and noticeced a split in
some parts of the pin block joining or near the frame, looking down from
the top.  I also noticed that the top bolts seemed to go all the way
through, so the traditional repair of drilling these all the way through
is moot. It looks like a carrage bold was used, and the head came in from
the back, and the nut and a cap nut put in front. (the tuning pin side).  
 I am wondering if this was from the factory.  
	By coincedence the next week I tuned an Everett console.  also from the
50's and noticed the same thing. The top plate bolts completely through
with the threaded end on the tuning pin side. .   I had never seen this on
an Everett, and I used to tune for a dealer who sold them, perhaps it is
something I never noticed.   The block to frame seams were solid in this
case.  

As far as the cracks in the Janssen, we are watching.  I don't see how
they can appear with the plate bolts going all the way through.  Maybe
it's just wood shrinkage, and NOT the pin block trying to pull away??? The
piano was at pitch. 

comments suggestions ?  

Thanks
