I’m gonna be trying my luck at a gravity-fed irrigation system this year for the garden. This requires a large, elevated water barrel. At ~50 gallons that’s gonna tip the scale at over 400lbs when fully-loaded.
Would a 3/4’’ sheet of plywood roughly 12’’ x 30’’ framed into 2×3s with 1/2’’ dadoes have any trouble supporting this load?
My thoughts are no, but I’ll most likely also put in a middle support for the stand this thing is going to be on. The stand will also be built to reinforce the bottom edge of the frame since this is where the weight will be transferred from the plywood. I’m more worried about sag in the middle and the rabbeted corners (they will be screwed). Here’s a quick Shetchup model of the base:
And the whole barrel (no platform; this will raise it up 36”):
It’s gonna be painted then lined with a couple sheets of 3mil plastic. Thanks.
