[pianotech] Miking center pins and broach set

[David Ilvedson]

I don't mic center pins very often, certainly not each center as I come to it when repinning... '-]  But I have found differences between Pianotek and Schaff.   For instance, in the last batch of 20.5 pins from both companies, I found the Pianotek slightly bigger than Schaff.  I actually like because it gives me another option.   You will find that most often you are using only 20.5 and 21 center pins.   Those are the ones to have a lot on hand...

Didn't someone say that in between sizes can be had for center pins?   Where?   That would be very helpful.   You will find that most often you are using only 20.5 and 21 center pins.   Those are the ones to have a lot on hand...

Greetings,

         Does anyone else out there mike their center pins? I had an instructor at UWO who always miked his. He said that he found that pins can vary in size. 
     I miked my broaches too and gaging by the way my broaches feel sliding through the mike jaws (with a very slight resistence, the Schaff #21 pins mike at .0525!  Are broaches .0005" larger than center pins? Sure seems that way.

Thanks in advance,
