  • Most techs swear by hot hide glue... There is a Titebond molding and trim glue which has gotten good reviews.

    My extractor had a "pip" to center the head on the shank that was too wide and expanded the shank and split the head. I filed it down and now it works great. Sometimes the glue will need a little soaking with water or vinegar to soften for extracting without damage.

  • I am about to purchase a hammer extractor for this job, to rehang the hammers. Is the glue weak enough that the extracting process doesn't damage the hammer or shank? What glue is best for re-hanging the hammers?

  • Your videos are extremely helpful.  Thank you for posting them.

  • I am a pro tuner and technician from East Europe,watching your videos with interest,there are some differences in procedures,but the principle is same as here.I have great respect for your skills.Thank you for sharing your knowledge.

  • There's one more thing, but you've probably done the work by now, and that is bending the hammer shank under heat. You will be surprised how effective that technique can be while also saving a lot of time especially on the concert scene. With care and attention you can even use a screwdriver to heat up the shank.

  • Where did you learn all this stuff? I'm starting to repair and tune pianos (in Argentina), but here if you ask somebody to teach you, forget it, you'd get nothing. they won't share information, and there isn't a school to learn this. I don't get it, there is so much work for all of us.Thanks for sharing this
