It's been quite a while since I used the "screw adjustable" type of Renner wippen, but I also had a similar experience. With the same weight of hammer and shank as well as knuckle size and placement, the spring was strong enough to lift (as his nose grows...) the entire action. :----O> Thanks, Glen for making the tool to fix this...or did I miss something in the weight/friction thang and it wasn't too strong in the first place??
