The piano has an immense amount of lead in the keys and I can't get any kind of decent touch weight - very low upweight.  I figure I should remove the leads and start from scratch. I carefully matched the Renner style wippens and the knuckle placement on the shanks.  The new wippen heels are about 3/16" smaller than the original therefore I've had to raise the capstans which I've polished and applied Prolube. </blockquote> I would plug the holes after determining the amount of lead needed. You just may place a lead back in a hole. Another method would be to first determine the required FW and then place the key front on a scale and tare it out. Then place leads of the same size over the old leads to see which ones to pop out. This would be less work. Another concern would be to have the capstan/cushion contact point intersect the line drawn from the bottom of the br hole to the wip center while the key is half way down. So you may need to adjust the height of the heel. I take it you will be using spring assist wippens. In that case the BW needs to be set higher with the springs off and fine tune the BW with the springs. Contact Dave Stanwood. Regards, Jon Page</html>
