To make a powerful puller, you will need a piece of pipe, an iron plate and a pair of pieces of reinforcement or round timber. By welding, all parts are connected into a useful tool. Due to the size and slot in the lower part, the puller is suitable for shafts of different diameters, which makes it universal.
A similar device can be purchased at the store, but it is much more interesting to do it yourself. The advantage of this tool will be its cost and reliability.
