If so then a hammer made with a good felt but is not stiff enough or to springy for the tone desired then a 5-1 lacquer acetone solution ,or whatever, will stiffen the felt & improve its rebound rate. On the other hand, it might be possible that on a hammer with a >bad felt quality with excessive inner friction may be stabilized to a better >level by lacquering. >> May I submit that the Inner friction of felt has always been a fairly esoteric & small consideration to the discussion of hammers even though it is a know factor & frankly to me personally not very useful.
