[CAUT] Down Weight Too High With New Hammers

[Brent Fischer]

Jon,  thanks for taking time out of your day to replay with picture, too.The WNG tutorial is excellent and they supply a nicely designedpress for the front rail. Yes, the bushings are press fit and hopefullystay in place, dab of CA glue perhaps on the sides while pressing.Haven't found any docs on their site on the bal. pin install. Thereis a .46 difference in the diameters so I don't know if they expectone to use the same system. Time to call. Unlike some, they arevery attentive
 to customer needs and I think know in a tough economywith new products they are like Harley Davidson trying to sell theKnucklehead in the depression years. One thing I would like to see before the dean asks me why I am putting black parts in theconcert grand is some real data on amplitude increase on Steinwaysusing Steinway hammers. Another  issue is how does this stiffness  relate to an artist? I once installed Yamaha front rail punchings on an artist's grand and took them out the same day because of the felt's hardness difference, so before I dive in with the state's money I would really like to hear some more testimony on the stiffness "feeling". thanks again JonBrent

... assume
you used the WNG 4mm capstan drill bit / question for you / angled jig
set up? planning on installing Kluge keyframe set on a B and will
replace front and bal. pins with WNG /any experience with this
retrofit / I've done a few new frame sets but no WNG  keypins
yet,


A #21 or 22 bit is sufficient. Here's a photo of my capstan and
back check drilling jig for my ShopSmith. The keys are indexed off the
back.
I have not had the opportunity to retrofit WGN key pins but am a
little leery of the need to shim them. Be careful when hammering,
as
David Stanwood pointed out a while ago, you can chip off the
material.


Regards,
