Main problems are: 1) Wippen rail needs to be relieved to clear bottome of wippen, otherwise the rail holds the wippen up off of the capstain. 2) The Wippen has a cast-in boss for assist springs, which interferes with the hammer tail. We'll have to cut off the spring boss. They suggested coving out the hammer a little more, but we'd rather have reliable checking. 3) Let-off button adjustment will be nearly bottomed out - we'll need to replace with longer buttons. 4) Drop screws will be turned down so low they'll be buried - we'll have to install thicker cushion on the rep lever. As to the suggestion to check the action spread, can't increase it because of the spring boss - hammer tail interference, and can't decrease it or the jack tender will be off the edge of the let-off button. I'll try to find the photos. We've test regulated samples of black WNG, new Renner, and the original WNG parts <br>
in all possible combinations, and the black WNG wippens cause problems in any combination, while the original WNG wippens work best and the Renner wippens are acceptable. <br>
