[pianotech] Blocks

[Dale Erwin]

Yep, and you're welcome. I make a composite multilam block with a 9mm 
Delignit cap. I'm the guy who introduced y'all to them, 
Well not exactly. I saw this idea on the Yamaha blocks first. But you did motivate me to go with it so...thanksA Great idea!
 I'd go with a smaller hole 
like you did, before I'd put in a longer pin.

Yep, and you're welcome. I make a composite multilam block with a 9mm 
Delignit cap. I'm the guy who introduced y'all to them, but my testing 
has convinced me that there's no difference worthy of the price between 
a high dollar plank and the cheap rotary cut supply house product with 
the same high quality cap. It's the cap that does most of the work, and 
I find it hard to put in an expensive quarter sawn block unless it's 
doing something wonderful while it's in there.

I use about 2-1/2 coils throughout, but my low bass core wire is 
typically 0.051" rather than 0.064", so the bass coils don't stack as 
deep. I don't find enough difference in torque from end to end double 
drilling, which I also introduced y'all to, to bother with different 
drill sizes. But it's whatever works to the satisfaction of all 
concerned that counts, whatever it takes to get there.

I sure wouldn't. One thing I for sure don't want in a piano is a long 
pin that's tight at the bottom. That's the whole point of the composite 
block with the 2-3/8" Denro pins that I use. I'd go with a smaller hole 
like you did, before I'd put in a longer pin.
