Patrick, this is the infamous Herrburger Brooks D-Type Spring & Loop action, discussed fairly extensively on the list just a few weeks ago. They NEVER feel like a proper repetition action, no matter what you do, because they simply aren't. If it feels sluggish just because centres are stiff, you could use Protek CLP, or whatever technique you use for tight centres. And a quick basic regulation. But it simply isn't worth trying more. The action did not feel like a proper repetition action even when it was brand new. Further, these cut-down actions were cheaper, therefore generally fitted to budget-end pianos, made down to a price and of indifferent quality. If your customer wants a fine piano, the solution is to buy one. The Dagmar wasn't one even when new. Best regards, David Boyce. > Hello, especially to our friends across the pond.
