My back is recovering from a recent injury and while I was planning to do some work with plywood in the shop this weekend my wife convinced me that there'll still be plywood at the store later and maybe I shouldn't push things. From recent experience, 50 lb (as in a bag of rock salt) is a bit more than I should be handling just yet. I'm also pleasantly surprised that my back is not telling me I am stupid from moving my carboy of must yesterday with 20 lb honey and 4 gallons water.
This has me wondering just how much a 4' by 8' sheet of 3/4" plywood weighs - does anyone here know? I will keep in mind that my body may be feeling more than just the dead weight due to torques and what not as it gets positioned for cutting.
