Thanks, In a way I'm glad that I won't have to dabble in the realms of servos yet...
Gene, I do usually have to measure the hole as it is most often the screw which is missing - or broken in the hole. I can usually get a pretty close measurement by screwing a wooden cocktail stick or skewer into the hole and measuring it as soon as it is unscrewed or by using Plastimorph (Jett Sett) - neither is exact as the wood usually expands a fraction when it comes free of the hole while the Plastimorph contracts slightly as it cools but I have always got 'good enough' measurements so far.. I usually measure them with a travelling microscope over several threads. Oh, and you can add at least a hundred years onto the age of the screws - not 75 years but 150 - 250 years and some of the screws probably haven't been moved in all that time until their heads have corroded off... fortunately, most are blued steel screws in brass plates and so they will 'disappear' in an Alum solution after a few days. -- Best wishes, Ian ____________ Ian W.
