Richard, I'd suggest that you didn't get the piano in proper condition, before = attempting to regulate. In other words, the tails of the hammers need to = be slightly surfaced, w/60 grit, accross the tails. And the backcheck = leather needs to be "surfaced", just as you would hammers. I use 100grit = for that job. It may well be that the tails are not shaped correctly. If this is the = case then some wire bending is in order to get the tail to interact = correctly with the backcheck. Not a biggee, but time consuming and a = royal pain, IMO. As for the Chickering Wippen springs...Yes they are a Royal Pain In The = A**! There are tools that will make the job a bit easier, but it is = still one of the most difficult actions to deal with, in this respect. = My sympathy goes out to you.
