Ball park figures: oak is 3.5 to 4 lbs. per board foot, making your lid
no more than 20lbs. That should be close enough to determine the needs
of your safety device.
I guess if you really wanted to split hairs, though, it would depend on
the width and depth of the top. I'm not sure exactly what safety devices
you are using, but if they are mounted on the hinge side, the load they
must support will increase as the front-to-rear depth of the top
Since you chose to quote my response, Woodman1, I feel compelled to
defend my honor! LOL!
I totally agree with you that this isn't rocket science....and that's
why I gave a very simple answer first. I merely included the second part
because I felt certain that some of the more technically-minded here
would be quick to point out that more than just the weight of the top
figures into the equation.
