Hey All,

My name is Hal and I finally decided to take up SFG. I bought Mel's book and I am using his tips wherever I can. I recently went to Lowe's and purchased some lumber to build a 4' x 2' x 6" box for an SFG. I have posted some pictures below. I have some questions about waterproofing and stability.
The floor of the box is sureply pine I believe. I was wondering if it is appropriate to have that as a floor with no wateproofing mechanism in place. Will the wood floor take on water damage and lose strength and stability? If so, what have you guys done to ensure this does not happen.
I was also wondering about stability. The box is ultimately going to hold 4 cubic feet of Mel's mix. I plan on placing the box on top of some sort of folding table on my back porch. I was wondering if you guys think this is adequate for stability. If not, what do you suggest?
