    I just love the open-faced pinblock. It's the best way to do it, IMHO.
    
    
    
    
    
    
    
    One major thing about them is that, during the rebuilding process, it allows one to correct a less-than perfect tuning pin array. But I just love how they feel during tuning - I can hardly wait to tune this baby!

    Okay Terry, just tell us if all your beckets are going to be facing the same direction once it is tuned. How did you do that?

    I just tuned a 100 year old (this year) Bechstein upright with an 
    open-face block.  It had half agraffes all the way up the scale from 
    the bottom.  Pulled it up 150 to 200 cents with regular overpull and 
    nothing broke.  It was sounding pretty decent on the third touch-up 
    pass.  Hammers were a little flat, robbing higher partials but what a 
    clean rich sound.
    
    Goes to show that buying a good piano now means you will have a good 
    piano for a couple generations.  Customer didn't know what she 
    had.  Her parents had bought it for her (long ago) for three hundred 
    pesos when there were three pesos to the dollar.  I could assure her 
    it was worth much more.
    
    A week before I was called to try to retrieve a no-name upright a few 
    decades younger.  About 1/4 of the strings snapped.  Action was 
    floppy and the bottom was broken, not supporting the pedals.  Quality 
    really is cheaper if you consider the instrument's useful lifetime.

    Oh , It's magic Alan &  only the select few have the magic becket dust...... 
    Nahhh . It's all  technique.  Trix does this routinely as well & it's  
    beautiful.

    I use a very simple little wooden shop-made jig, the design of which, if my memory is correct, I got from Jon Page some years ago. Simple and works great. Use a decent hardwood - I chose a piece of black cherry cut from the frame of my college waterbed. As you can see in the picture below, you simply position the wire in the jig (jig holds wire fairly snug), pull the jig back to align it with the tuning pin hole (left side of jig), and then cut the wire flush with the right side of the jig. My jig is exactly three inches long. 
    
    I cut a length of wire for two strings, put a bend in the middle, place the bend over the hitch pin, place a small clamp on the hitch pin to hold the string there, run the wire straight over the bridge, place the wire in the jig, pull the wire snug with my fingers, position jig and cut.
    
    
    
    
    Below is a close-up of the jig side pictured above.
    
    
    
    
    Below is a picture of the other side. The little diagram on the right side is an alignment guide - align the rear edge of the jig with the middle of the tuning pin hole for the treble and at the rear edge for bass (thinner wire needs to be shorter than thicker wire for the same becket position). As you move from treble to bass, you simply keep positioning the jig a little further toward the rear of the tuning pin hole. In practice, you really need to experiment with a few wires to get your technique down. Much depends on how tight you make your bend at the hitch pin, if you feed the wire through the bridge pins, and how tightly you pull the string. The key is to be consistent. If you can be consistent with each wire, this jig will help you get picture-perfect becket positioning.
    
    
    
    Note to David Love: 
    Notice that I countersunk the edges of my tuning pin holes as you suggested. I did the countersinking after my initial 1/4" hole drilling. After enlarging the hole on the final drill pass with a 0.265" bit, much of the countersink was consumed, but some remained - a nice little amount IMHO. (The first picture above has only seen the first 1/4" drilling pass.) At first I thought it looked really crappy, but once you get the pins in there with strings on, you really would need to be told the holes were countersunk to see it. Thanks for the tip.

    It's a pin height gage too.

    The Beauty of the Open-Faced PinblockOn this piano I am keeping the bottoms of my coils about 4 mm off the pinblock (one good coil thickness/height). Rather than measuring to the top of the pin, I place a small rectangular piece of maple 4 mm thick at the base of the coil. Then as I pound the pin in with my air hammer, I simply stop when the snugged coil bottom just touches the wood gauge. Seems to work quite well and addresses the question of how to measure pin height when using an air hammer.

    Yes, aren't they, though. From an older Bosendorfer we did some time back --

    This is my latest little attempt to get those beckets lined up.  The  curved 
    tube was the first attempt but the larger wire would catch in the  tube so I 
    made another one with steeper angle and straight tube and it  works well.
    I made the second one in haste hand turning the delrin  dowel against a belt 
    sander before inserting copper tube of course so its a  little imperfect but 
    one could make a nice one with a  lathe.  The scary part is I'm not sure if the 
    police would like the  looks of it, so it stays in the shop.

    Nice tool but it looks a little cumbersome to use.  The two following 
    links have photos of
    gages which secure the wire in place. Also notice the indexing 
    markings for tool placement,
    wire in the treble needs to have the tool index from the center of 
    the hole where as you
    get lower in the scale the indexing migrates towards the rear of the 
    hole.  This maintains
    the becket alignment through the scale.  Also simpler to make.
