Whether you need to work out some aggression or you just want to keep your boxing or martial-arts skills sharp, a punching bag is an essential tool for meeting your training needs. Although most bags are suspended by a chain from the ceiling, sometimes suspension is not an option. Fortunately, building a stand for your punching bag is a fairly simple process.
Screw four of the 4-foot pipe lengths into the five-way splitter, then put a cap on each free end. This is the base of the stand.
Insert the 8-foot pipe in the fifth slot on the five-way splitter. Put the three-way splitter on the other end of the 8-foot pipe.
Place the remaining 4-foot pipe sections in the other ends of the three-way splitter, then cap the free ends of the pipes.
Weld the two iron rings about 6 inches from the far ends of each of the two top pipes. These will serve as the hook points for the bag and the counterweight.
Use the chain from the bag to secure the punching bag to one of the upper arms, from the welded ring. Secure your counterweight to the other side.
