I've done a few of these by simply filing & tapering the hammers and arcing the tails. About a gram/hammer is removed, plus repinning reduces friction. This overall effect lowers the touchweight. Addressing the FW targets BW. The two I have on file did not have assist springs. There was no capstan relocating but it brought the actions into comfortable playing ranges. Estimated charge $750 to $1200. Regards, Jon Page
