This method is very similar to bending bars using hands. A hickey bar is a metal bar with 3 fingers or studs. It is also called a 3 pin bar bender.
These studs are there to hold the rebar in position. The bar is around 34 inches long and weighs around 4 pounds. It uses the principle of increasing the torque to bend the reinforcement bar. People prefer it because of its small size and portability.
The handle of the hickey bar is designed as such to give considerable pressure to bend the rebar. Its use is such that one bar is not enough to bend the bar, you always need two of these.
If one of the studs breaks, you can always fix it using a torch and a grinder. You can always shorten the length of the bar using a hacksaw.
The process starts with placing the rebar straight on the ground.
Hold it using one of the hickey bars. Hold it in such a way that the rebar passes through two of the studs. Remember to use two hickey bars to bend the rebar. Now use the second hickey bar and again hold the bar using it.
The distance between the two holdings is where the bar will bend. So, the shorter the distance, the more accurate will be the point of the bend. Now, apply force to the second hickey bar. This will create torque and will make bending the bar very easy.
Angle control is very important. It would be helpful if a second person could use a measuring square to check the angle of bend during the process.
While it has its advantages, it also has some limitations.
- You cannot use it for Grade 60 and above.
- The maximum diameter of the bar also depends upon the distance between the studs.
- Usually, it cannot bend bars of more than 5/8 inches.
