[CAUT] strange rib damage

[David Love]

God no! Calculate it. 35000 lbs of tension, 1 degree of bearing average. Don't have the formula in my head but it comes in around 500 lbs.

All,

This talk about the bellyman has me wondering 2 things; have I ever inadvertently caused such damage, because I certainly am a large person and have carved many a bridge, and secondly, how much pressure is exerted on the board when fully strung? I think I have an idea, but certainly this is more than my ample 250 pounds.
