how much pressure is exerted on the board when fully strung? I seem to remember reading somewhere that at 1 1/2 degrees downbearing each string would be exerting about 3-4 pounds of downward pressure, which would yield between 700 and 1,000 pounds total. Along these lines, I was once part of a quartet of adults (with an average weight of around 200 pounds) recruited to stand on a bridge for the purpose of setting downbearing under simulated load.

I think I have an idea, but certainly this is more than my ample 250 pounds. Jim -------------- next part -------------- An HTML attachment was scrubbed...
