    I believe the 444a has a much stronger smell but it may be the other way round. ------------------------------ David C. Brown RPT Garland TX tunermandb88.com ------------------------------

    RE: Key bushing glue?

    Posted in: Pianotech

    I've used Elmer's School Glue for years without any problems. It's water soluble and will adhere to the residue of the old heat activated glue you find on a lot of mid 20th century keyboards. I remove the old bushings with cheap vodka with a little wallpaper ...

    I typically split the hammers off with diagonal cutting pliars, but I have extracted hammers that I needed to save using a punch. I made an anvil out of a wood block in a vise with a hammer shank sized hole (oversized) and used a punch made from an appropriately ...

    I would check the key bed, especially any shims or wedges that attach the keybed to the plate.  Also, it has been demonstrated that because upright pianos have four wheels, an uneven floor can stress the structure of the piano and even affect the tuning.  ...

    RE: D hammer removal

    Posted in: CAUT

    A heat gun is efficient and fast. Heat the joint from the top and bottom.  Keep the heat gun moving. Don't burn the shanks. A regular pair of extractor pliers is all you need. You can often do one full section at a time, certainly half, it doesn't matter ...

    RE: Key bushing glue?

    Posted in: Pianotech

    Cold hide glue for decades now. It's basically hide glue with urea. It's the right consistency. It holds fine for bushings. The trick is learning how much is too much or too little. That doesn't change with the type of glue you use. If you get squeeze ...

    Hi Dave,  I second Kevin's suggestion -- using a heat gun on 1-4 hammers at a time, then plucking them off with an hammer extractor plier. At least on the Hamburg grands, that method works well and it is very fast. I haven't timed myself, but 10-15 ...

    Hot hide for me. 47 years and counting. I do add a little urea for retardation. Just enough to make my Bushmaster process efficient. I have to remind myself to dump the glue afterward so I don't "forget" that it is retarded (i.e. altered). Made that mistake ...

    I don't do that.  I found that paint on the damper heads sometimes started to come up so I gave up soaking.  I just put them in a bench vice upside down and remove the old felt with a sharp chisel.  Comes off easily along with the glue.  While the damper ...

    I use an eye dropper to drip vinegar on the felts. It's all natural and way safer than wallpaper remover, and won't damage the paint. It’s considerably cheaper too. It takes about 15 minutes to do, then let it sit for about half an hour or so. When you ...
