[CAUT] Bösendorfer question

[Alan Eder]

Hi Roger,


Thanks for the input on key bushing with leather.  Nap towards the pin, eh?  Not what I would have guessed (but I have zero experience bushing keys with leather at the moment, so what do I know?).  Do you use hot animal hide glue?  Any special considerations (vs. bushing w/ cloth)? 

If mymemory serves me correctly I use 1.1mm.
... which would be about .043".  I suppose the appropriate thickness of leather depends, as with cloth, on the difference between the size of the mortise and the size of the key pins (less whatever needs to be figured in for the glue line--and I imagine that leather will be less absorbent of glue than cloth, particularly if the glue is applied to the tanned side of the leather).


Have you found leather to last substantially longer than cloth?  And as it starts to wear, is there a way to resuscitate it (like there is with cloth)?


Many thanks,


Alan Eder

Hi Alan,
             Get your leather from Jurgen at Piano Forte he sells it in severalthicknesses, 0.1mm increments. I use it with the nap towards the pins,dusted with micro fine Teflon powder. No squeaky leather.  If mymemory serves me correctly I use 1.1mm.

Regards Roger

Stan,

I have worked on many Bosendorfers and the keypin diameters were.135". In fact I am doing one now, and it too has .135" on bothrails. I will be rebushing with leather. The keys are made by HerrbergerBrooks (UK) but this size seems to be common with Europeanpianos.

Hello all,


Have just received a set of Bösendorfer keys from a colleague forrebushing and am worried that the keypin diameters may not have beenmeasured accurately.  Is anyone able to share these specs?


Best regards from the sun-baked Canadian prairie!
