Impact hammer

    I used an old impact tuning hammer for the first time yesterday on two spinet pianos (see pic). I'm borrowing it from a friend who needs it back soon. I was pleasantly surprised. Although it took a little longer than using my normal extension hammer, it wasn't by that much which makes me think the learning curve may not be as daunting as I thought it might be. My back also felt considerably better afterwards.  

    I'm looking into the Reyburn Cyber Hammers, particularly the 200 series.  For those who have experience with it, will it be a significantly different experience from what I used? If so, how? Even though $325 is not a terribly large expense in the grand scheme, it's not one that I want to purchase and then not use. I checked eBay to find a used one, but everybody must like them. 😂

     Thank you!

    Mr. Foster,

    for what it's worth, what you have is a standard, John Ford extension hammer handle that someone has put an impact hammer, head and shank in after removing the end weight. You have to admire the ingenuity, but it's not going to work on anything that doesn't have very loose tuning pins. I bought one of the original Frances Mehaffey impact hammers back in 1983 and was very useful in some cases. Back in 2010. I got a Reyburn impact hammer when a young friend bought one and didn’t like it. I bought it from him because it was too much money for him to write off. It is so much better than what I was used to that I haven’t used the Mehaffey hammer since. If saving your back and shoulders is an issue, I would strongly recommend investing in one.

    Hi Tim,

    Any of the Reyburn CyberHammers will be a huge step up from the old style impact hammers. My first CyberHammer was used (probably close to 20 years old) and lasted five years before it completely gave out. Then I upgraded to the current 700 series. What a difference, even between the two! 

    To me it's always been worth the investment. The learning curve is not too bad for most people. The cost of one is significantly less than any medical treatment for your back or shoulders. You only get one body. Do whatever you can now to protect and preserve it so in 30 years you're still able to do what you want to do.

    I migrated to an impact hammer hoping to avoid shoulder surgery. I had been a right-handed tuner up to that point.

    My first intervention was to switch to the left hand when I tuned the high treble in grands. It saved time and gave my shoulder a little break. 


    Yes, yes to impact hammers. I took the left-hand tuning further when I got a Reyburn impact hammer. I taught myself tuning with the impact hammer left-handed. I had not been taught tuning uprights left-handed with a traditional tuning hammer. But tuning uprights left-handed makes sense because the string feeds onto the tuning pin from the opposite side. So the leverage is better, tuning left handed. You can use your body weight to push down on the tuning hammer. Others argue that the pin flexion is less and therefore the tuning is more stable. 


    My personal experience with upright impact hammers is that it takes me less physical energy. Except for very tight pins, it saves me time. But most of all, my tunings are more accurate and stable. I don't lose time over worry, whether the pin turned or was just twisted!

    Hi Tim

    I very curious about the impact lever in your picture. It appears to be an impact mechanism that plugs into an extension lever handle. Is this what we're looking at?
    If so, do you know who made this and when? I assume that it belongs to another tech.

    Thanks

    Craig,

    I thought the same thing. I would bet it's an early Mehaffey unit.  Or , on second look a Ford unit. The handle resembles what Ford used to put out.

    I 100% agree with Maria, It is a very easy transition to switch to left handed tuning with the impact (assuming you are normally right handed). The amount of energy spent with the impact is so much less, resulting in a painless tuning. It's a natural flick of the wrist with little shoulder or back exertion. I am in my 46th year of tuning, picking up the impact less than 10 years ago. Tunings on uprights are extremely stable, and on pitch raises, your risk of breaking strings will be almost non existent. The Rayburn is top quality and my go to hammer,  however, I carry the Schaff impact hammer in my vehicle as well for tight tuning pins or the frightful pianos that have not seen a piano tuner for many decades. The impacts are my most valuable tools that I own. They are a great addition to my carbon fiber ball hammer (yes, I use all three hammers, depending upon the situation). In short, when it comes to tuning, I don't believe in the old saying "no pain, no gain".

    I have been hesitant to get an impact hammer (as I think I have mentioned before) due to being concerned that their use shortens the life of the pin block. A smooth stress on wood fibers being less likely to cause a rupture than a sharp impact. My view. Any validity, in your opinion? If you remember how they used to package purchases at a bakery (box and thin cotton string), you know what I am referring to.


    Also, good on doing ambidextrous tuning. Right-handed for grands, and left-handed for uprights -- again, less stress on the pin block and also gives a stable tuning with an accompanying proper approach to settling the pin. If you put your mind to it, left-handed tuning (for a right-handed person like me) becomes natural.

    Norm,
    I think the results are quite the opposite in extending pinblick life. The impact hammer keeps the user from flagpoling the pin and often the desired pitch can be achieved in one swift motion rather than multiple smaller moves. 


    Tim- the tuning tuning lever does not appear to be an impact lever at all but a regular lever that can be extended. Very different animal. An impact hammer is weighted at the top of the lever, the hand is placed at the bottom by the tip, and the impact of the weight is "thrown" as the hand jerks the handle. Much easier to do than explain. 


    A demo is at the reyburn tools.com website.

    Hi all,

    The tuning hammer has no markings that I can see.  The brass portion tightens against the head that can screw off. It is not an extension hammer for sure (my regular hammer is the extension type). It receives a standard tip and belongs to an RPT friend who has been helping me. He suggested I give it a try after watching me tune and after observing my "style," very helpfully suggested that an impact might suit me well for uprights.

    Jeannie, it's definitely an impact hammer (see photo), but it doesn't look like most of the ones I've seen.

    One of the things I noticed right away is that I could much more easily switch hands.  I tune both grands and uprights with my right hand but I found that I could switch fairly easily, especially in the bass which made things much more comfortable.

    Ah, I can see now that someone took the old style mechanism and adapted it for a regular extension lever. Is the end of the hammer weighted?

    It's not weighted. The really tight pins were a little difficult to move.

    So, here’s the difference between what you’ve got and a true impact hammer. Without the weight to throw the lever you’ll be working way too hard at your wrist. The mechanism in the CyberHammer is an improved design over what you’re using. Be careful not to cause injury.

    Hello All;
    I was doing an average of 25 tunings a week a couple of years ago and needed to have surgery on my right shoulder. I am VERY right handed and had tried a stint with ambidexterity a few years before with an impact hammer using my left hand. it worked out very well. After the surgery on my right shoulder I used my left arm and the impact wrench to do precise tunings. The only caveat is that I had to be very careful when I got to the sides of the piano so as not to mark them by the top of the wrench striking the finish.
