Hi List, I've a small grand that I'm regulating (mine) and I'm struggling with checking. Just finished regulation, and everything works well except checking. Checking is nice and even throughout from a medium blow on up at 15mm. I've double checked things like: repetition spring tension - definitely not too strong; escapement - jack is clearing knuckle sufficiently; backcheck height and angle seem right. I guess my thoughts now lean towards, maybe backchecks are too low? I can get checking on a soft blow by decreasing the checking height from 15mm to about 8 or 9, but I just don't like it that close. Thoughts? and Thanks. William R. Monroe Madison, WI Assoc.
