In short...I need to build a exterior wooden support structure that can hold a sand filled box 3'tall x 4' wide x 13" deep...weighing roughly 1400lbs.
The support structure needs to be at least 1 foot wider & longer and stand approximately 3 feet tall. Making the entire combined height 6 feet tall. I'm not sure what dimensions wood to use to support that weight nor how to design it.
This supporting structure will be sitting on the ground. I want it to be "temporary". As I do not want a permanent concrete pad for ground support. I do realize the problem with that idea. If there is a way to get around making a permanent base, that would be ideal.
I thought about using railroad ties and as a ground level base to help with elemental degradation, but have no easy way to cut something that thick.
Any ideas will be so much appreciated!
