What is the difference between the X-shaped base and H-shaped base?
The X-shaped base has 4 legs made of cast aluminium. See Picture 32-1. Although the gross weight is not heavy, but the material cost is higher. It is mandatory for stringing machine factory to design and create the mold in order to cast the legs. The H-shaped base utilizes 3 iron pipes welded together which forms the base. See Picture 32-2. Since a mold is not required, it is cheaper to produce a H-shaped base than an X-shaped base. The gross weight of the H-shaped base is heavier and may increase the shipping cost. The X-shaped base is far more attractive than the H-shaped base.
