Strength, balance, flexibility, and technique are the four most important aspects that a bull rider needs to work on. You need to keep these traits in mind when designing training equipment for bull riding.
Bucking barrel is one of the most pieces of equipment required by a bull rider. The suspended piece of equipment helps you cling to the bull as well as protecting your friends from getting hurt as well. Get a shovel and dig 4 holes in the ground about 7 feet apart. The depth of the holes should be around the 3 foot mark. You may use a gasoline powered auger or an electric digger for this step.
Put water in all holes and allow it ample time to seep into the ground. Prepare concrete according to the given formula on the cement bags and add water to the mixture slowly while at the same time mixing it up with shovel. You do not need to make the mixture too watery as concrete will soak moisture (if needed) from the earth.
You may add small rocks in the mixture to add strength. The concrete should pop out no more than 12 inches out of the ground. Mark a post about 8 inches from the ground and use a drill machine to create screw holes in the concrete pillar.
You should use industry grade high quality screws in the above created holes. Attach eye hooks to the screws and install lock tight to the screws for additional safety.
Cut rope into 6 feet long pieces and pass it through the eye hooks in the concrete pillars to form a rectangle. You should tie a clamp at the end points of the rope for additional stability.
