Sure, that's why I had no negative opinion about it, other than the fact that it dries up fast and is therefor a little harder to carry around. > > 'some technician' - has observed that lacquers and other hardning > agents tend to coat the fibers of hammer felt making them brittle and > essentially destroying their resilent capabitlites.

All hardeners clot the wool fibers up to a degree. that's why they are called hardeners. I am against them on principle except for the outer extremities of the keyboard i.e. the highest notes and the lowest notes. > > As for collodium .... grin... you are wrong about its primary benifit > Andre !

If I want to get high, that makes it all the more attractive as well ... *((: >))) la-la-la-la-la.... > > Oh.... and Terry... yep.. some folks are out there hardening Yamaha > hammers.

And in the case of Quentins remark about hammer dope used on Yamaha's : He indeed means applying some hardener on hammers belonging to a CFIII-S, the concert grand which has ..... Wurzen felt. usually the lowest and highest Wurzen hammers could use some extra 'spritz', that's the price for less needling and easier needling. greets > > Cheers > RicB > > > > > Andre writes: > > /My "weapon of choice" is collodium (or collodion) because it is a > natural hardener, mixed with alcohol and ether. > > The ether smells badly for a short time, but the advantage of this is > that it is easy to apply (with a pipette), easy to take along (in a > small glass bottle) as a standard tool case item for the traveling > technician, it will stay the way it is (it does not harden out but > stays liquid), after 1 hour we get a result and after 1 day the > stuff has done its work completely/ > > > _______________________________________________ > pianotech list info: https://www.moypiano.com/resources/#archives > > friendly greetings from André Oorebeek www.concertpianoservice.nl "Where music is no harm can be"
