west system in blocks

I went ahead and treated the bass holes with CA glue. I had dosed a number 
of pins in the upper section after finding that they were not tight enough to 
suit me. The thin CA did help, giving an additional 20 or so in/lbs. However, 
in the bass, I put a newspaper under the block and dosed the holes with the 
CA before I strung. I was using a nozzle to get below the top of the block, 
(I didn't want to really glue the plate to block!), and I used a liberal 
amount. 
After 20 minutes or so, (it is humid around here, these days), I could 
no longer smell CA around the block, so I began. I used 4/0 pins and it was 
dramatic how much tighter the pins were! Most of these pins are around 125 
in/lbs. So, it seems that there is much better results from treating the hole 
before the pin went in. 
I take notes on my work, so I will be able to track the long term results 
of various means of application on this piano. I would certainly have 
preferred to put in a new block, but that simply wasn't in the budget.

Ed, Did you find that the pins "squeeked" ? On a couple of occasions I have tried tightening a loose tuning pin by removing the pin and treating the hole. However, I used catalyst to harden the glue before driving the pin back into the block. It was tight enough but had a fairly loud squeek when turning the pin!

Perhaps I should not have used the catalyst.
