>The only Wegman I have seen was an upright. It has no pinblock, per se. There is a chunk of wood where the pinblock should be. It is a structural member of the back, but it is not functionally a pinblock. The tuning pins do not penetrate it and are not imbedded in it. The tuning pin look like a traditional tuning pin with the threaded part of its length cut off. The pins are held in place by friction with the plate itself. The plate holes, to engage the pins, are an inverted teardrop shape. The tension of the string pulls the pin into the narrower part of this teardrop hole. When a string breaks, the pin just pops out of the plate hole. In the absence of tension on the string, there is nothing to hold the pin in place. There is no pinblock to be replaced. The big problem is the stringing process. Where a single length of string doubles around a single hitch pin, the two tuning pins have to be turned simultaneously until there is enough tension on both segments to produce enough friction between the pins and the teardrop holes that the pins don't just fall out. Maybe the grands are different, or maybe they evolved differently over time, but this is an example of the one Wegman in my personal experience. Frank Emerson< Thanks, Frank. I've worked on the uprights, and you're description is exactly what I've seen. My daughter, in fact, has one that I refinished for her, and it actually has a pretty stable tuning. What I would like to know is if their grands are the same deal. Anyone know? Chuck -------------- next part -------------- An HTML attachment was scrubbed...
