  • 1.  Changing the tuning TIP on an impact wrench

    Posted 11-21-2019 17:58
    Hi, I posted this to the wrong group earlier.

    How do I change the tuning tip on an impact tuning hammer?

    Howard Piano sells the hammer and an item called a 'impact tuning tip remover'.

    I have both the wrench and the tip remover.

    The remover tool looks like an Allen wrench of sorts and it looks like what you are supposed to do is put one end inside the tuning tip and 'wrench' the tuning tip off (of the impact wrench).

    But it does not budge when I try that.

    What is the secret?

    Hi Hank,

    I'd recommend contacting Nate Reyburn at Reyburntools.com. He'll be able to walk you though how to disassemble one if need be. 

    So... why do you feel you have to remove the tip?

    Personally, I don't think you need to change tips, unless the one that's on there is all torn up on the inside. Impact lever tips do not need to go all the way down on the pin like the traditional style lever tips do. This is because there's no need to flagpole the pin. They only need to go down enough to grasp the pin enough to bump it around. A number 2 tip accomplishes this on 99% of uprights I've seen.

    Put the tip wrench on the floor. Stand on the tip wrench and turn the tuning lever. 

    You'll want to do this on a carpeted floor (or shop floor) or it will leave marks.

    If that's a CyberHammer impact tuning hammer with a Balance Drive (sounds like it might be? Any of our CyberHammers from the last several years would fall into this category), it has a 1/8" hex/allen drive on the back. That lets you remove the entire EXTENSION assembly in one piece quickly.

    Removing the TUNING TIP on ANY CyberHammer is exactly the same as on any other normal tuning lever. You need a tuning tip wrench. If you don't have one, they're available from Pianotek, Schaff, etc. Standard tool for piano tuners that you eventually need to have if you're a pro tuner. Procedure is simply righty-tighty, lefty-loosey. Place over knee or on ground, use leverage, unscrew.

    To install a new tuning tip (again, this is universal for tuning levers), just screw it on and snug it up. You don't need much torque. What you can get from tip wrench and your hands without exerting yourself in any way is MORE than enough. The tip actually tightens down during use. I've goofed up test driving prototype CyberHammers that I forgot to tighten the tip onto at all, and was able to get through tunings just with that effect.

    I now carry multiple tip wrenches and backup tools :P

    Hope that helps.
