Well, I got some old steel bar (free)2" x 3" that that I cut into 2' lengths and I am going to make up a steel box and stack the bars in the box. I weighed one bar and I have a total weight of 400 lbs. Do you think that will be enough weight or sohould I be shooting for a 1000lb like the barrels. I wish I had seen the barrel before I started to cut up the steel bar, the barrel looks great.
