More Isn't Always Better

I thought steel casters would look cool since all the hardware was galvanized metal. I started with three, but could tell the barrel was going to easily tip. To solve the problem I added three more for a total of six. This design also eventually failed because the barrel was at risk of tipping when the heavy lid was open. The final solution was to construct extended legs with 2x4's to position the casters far enough out from the barrel's base to prevent tipping.
