Hi Richard, Good checking is when the hammer tail will rub the backchecks on a large part of the tail with a nice scratchy noise if the hammer is in drop and pushed down, and IS NOT rubbing the backchecks when rising and being restricted (shank flexed slightly) with a finger. I test also the angle, with a tool, and the relative move between tail and backchecks (visually) to verify the angle correctness. The noise of the checking is a good indication for sure. I know no other method to avoid the undue rubbing of the tail before the stroke. Which other method do you envisage ? Isaac > Which one would that be...? I know of at least three. And all three of them could be improved upon and quite probably IMHO the chalk idea could be just one such improvement... In any case it makes for a good out of the piano test without having to get all kinds of fancy equipment to measure things. Worth a try before being simply dismissed without further ado if you ask me. >>>>>
