<HTML> <HEAD> <TITLE>Re: [CAUT] measuring wippen weight</TITLE> </HEAD> <BODY> Hey, Barbara, In my (limited) experience, most of the time the wippen heel is very close to being directly under the center of mass of the wippen.  In other words, if you measure WW in the prescribed manner vs. just putting the wippen on the scale, you will see very little difference in the scale reading.  It is possible that you just moved the heel from slightly in front of the CM to slightly behind it.  Try putting a wippen on the scale and just weighing it.  If it is a little over 17, chances are your new WW is just a little over the actual weight. My weighty opinion, Ken Z.

This wippen set up is the best (of the many) I've tried--feels good, less friction.  I'm just curious about the numbers.
