    On Amazon they call them square recess drivers. Lots of offerings, nice Klein set. Jon, what size do you use for actions? ------------------------------ Steven Rosenthal Honolulu HI 808-521-7129 ------------------------------

    A square drive tip is imperative to have. I purchased a 6" shaft w/ hex drive for a drill. I cut off the hex portion and angled the end to fit my combo handle. I ground the tip to produce a 'ball-end' to accommodate angular drive. Square drive beats Phillips ...

    Here's a set I haven't got installed yet.  Would anybody like to corroborate my measurements?  This is one of the two types of sets.  Maybe somebody can post dimensions for the other. Bracket thickness is 11.4 mm along the perimeter.  I can just force ...

    I use a tapered drill set to drill any new holes needed for the new brackets. I believe the back feet on the new brackets are on the rear and are also higher so it requires longer screws. I have had to chisel out some of the key frame to position the ...

    RE: Jack alignment

    Posted in: Pianotech

    I think what I have done is set the jack so it doesn't jam the stop felt when the action is at maximum dip and the knuckle doesn't hit the jack as it comes into check. Say ,420 dip. The jack should sit nicely in the window between the knuckle and the ...

    There are so many variables in ordering from Ronsen. You pick the weight of the cut and therefore the density.  The 16lb cut will start with a 12 1/2 gr hammer depending on which molding you choose. If you custom prep the hammers, Ronsen is the choice. ...

    Since brackets are scarce, duplicating the two good ones is the option to have some on hand when the pickin's are slim. I'd buy a set to have on hand. I wonder if pocket hole screw-downs is viable. Or just a wedge cut out of the front and back edges ...

    Jon, Wouldn't that require that you would actually have good brackets from which to make copies? Then you would already have a good set to install, hence no need to find one. That's kind of a moot point. -- Dave Conte, RPT, CCT Dave Conte ...

    Wooden replacements can be used until the factory ones arrive.  I would treat the exposed ply's with epoxy or CA to reinforce and then coat all surfaces with shellac. A handy upgrade might be to install a capstan on the bracket in front of the repetition ...

    Thank you Karl. I do understand that this piano was manufactured before Yamaha was using Wurzen felt for their CF series.  When I refer above to the hammers Yamaha was supplying "at that time", I was referring to the time of the comments in 2002 from ...

    Replace the end brackets first with the center brackets still screwed down. This will keep the rails' location. Then replace the center brackets with the end ones fastened down.  I'd pay two to three times the manufacturers price for wooden ones to not ...

    I just wanted to say, I replaced a set recently, and it became a big nightmare because the new brackets were a very tight fit on the frame. Consequently, after shoehorning the stack on the frame and screwing it down, I noticed the hammer rail had a slight ...

  • Posted in: Pianotech

    There are two distinct sets/types  of brackets so you need to match the brackets to what is in the piano with the expanding bracket issue. You also may have to drill holes in different locations on the action frame and do a little chisel work to set the ...

  • Posted in: Pianotech

    Yes, I suppose they could be cut from sheet metal. They would require machining afterward, I suppose, but I assume the castings did, too. I've never tried 3-D printing, but if the design were digitized, they would be available into the distant future. ...

    Or jump ship altogether. You could do this using brackets from a discarded old cheap stencil grand, or buy  a frame from WNG or Renner.  That involves other costs, obviously.  I generally save old frames when I design a WNG action. ------------------------------ ...

    RE: leveling keys

    Posted in: Pianotech

    That means that you altered the level by adjusting the angle of the pin. A minor bend can affect the lever angle by changing the position of the rear and center of the key resting points..  When doing so, I'd be more concerned about the fronts being in-line ...

    RE: leveling keys

    A crowned key level does not preserve the dip. The dip is set the same across the keyboard after leveling. So if the level drops in the center, the dip becomes shallow unless the front rail punching have proportionally compressed. I think Steinway set ...

    Hmmmm. I may have this wrong but I don't think Wurzen felt existed in 1986. My understanding was that the company started after the fall of the Berlin wall in1989. In 1991 Klaus and Jack Brand Re-privatized the Weikert felt plant in Wurzen which had been ...
