[CAUT] tuning pins on a Samick

[David Ilvedson]

You have tapped the pins a couple of times before because you have loose tuning pins, right?   Did you have any torque numbers?  Why were you tapping the pins?  Aren't your tuning pin coils right on the plate now?   This would have been the perfect situation (before you went through lamination) for CA glue.   It would have done a much better job of tightening up the tuning pins.   The pinblock already had a problem if you were tapping tuning pins several times.   I'm not I would put all the cost of a new pinblock on the technician...



I think that first lamination is the only separation.

i actually wasn't replacing the pins, just driving the one that were already there.



"Why are you driving them so far through the block?

When they go that far, they must be pushing the jack away from the block."

i made the mistake of not checking whether they were too long or not. 

i had done that two or three times before on other pianos, but the pins were short enough that they didn't protrude through the bottom of the PB, so i forgot to check. oops.



Do you have a support between the keybed and the floor?

yes i did have support between the keybed and the floor...the piano legs. (SORRY, JUST KIDDING.)

i used my pinblock support, the kind with two pieces of laminated hardwood two large bolts. 

i had a piece of high density fiberboard between the support and the keybed.



"...you owe your customer a new pinblock as well."

"Sorry, but I'd say that this block is a do-over."



well...crap.



i guess there's really no way to tell if the damage is deeper than the first lamination.

so it sounds like most everyone's professional opinion is to put in a new PB?
