Barb, If "front heavy" means heel moved towards the jack, the result is a lower WW. Heel moved towards the flange will be a higher WW. I put a heel on a rep at an extreme position towards the flange and balanced it on the scale. I could get as high as a 20 gram WW and then the rep would not stay on the jig (which might be your original question). The heel position was so extreme at that point, that one might question whether this design will function well this far out of the box.

I will give your suggestions a try. So, in the great scheme of things, is there something I should know about front heavy wippens?

You can then turn the jig around for two different angles. Make sure you have soaked the jig felt in lacquer to stiffen it and create a bit more friction. You can also slightly rough up the bottom of the angled flange that sits on the roller or put a bit of spray adhesive on it temporarily.

Be joyful that I'm not going to tell the story of all the testing I've done on this action. Anyway, besides replacing the flanges (obviously), I'm having to move the heel backwards (toward the flange). When the wips were in their original state, the WW was 17. Now with the heels moved and the little/angled Knabe flanges on, I can't get the wip to balance so I can get a reading. Do I just hold it lightly against the "tower?" or tie it with thread or use a rubber band or just ignore it? This wippen set up is the best (of the many) I've tried--feels good, less friction. I'm just curious about the numbers. Thanks, Barbara Richmond, RPT near Peoria, Illinois -------------- next part -------------- An HTML attachment was scrubbed...
