I saw a jig for bench regulating once at Vintage Pianos (I think they were called) in the north Seattle area that one of the Fandrich boys put together. It was set up if I remember so that you could pretty faithfully re-create the key bed and get really good bench regulating results. Maybe Del can say something about this, or even perhaps provide us with a picture of said. ??

I set my boards to string height and roughed in blow distance and jack position( 1/4" out). Started through letoff and the sharp dip was about right but the whites, the dip was so shallow the hammer rise was shy of letoff by 1/2". I know you can't set dip out of the piano and realized I should have measured the dip because now I'm wondering if the tech that wound all the adjustments out, messed with the dip so as not to break the jack off against the stop. In this case, the drop screws came up 3 turns and the let off buttons 5 turns. So now I'm thinking I should have shimmed the balance rail up to get enough dip so I could set let off. My aching back tells me I'm doing way too much work in the piano. It would be so nice to duplicate the bedding, so the amount of refinement in the piano was minimized. Dale Erwin said I could take sample dip reading of every C and shim the rails to duplicate the dip.Does anybody have any other methods? Would it be better to take the sample dip readings at the notes next to the bedding bolts.Your thoughts please.Keith R</blockquote> -- Richard Brekne RPT, N.P.T.F.
