Product Descriptions

Coil springs are usually attached to webbing using a clinch it tool or button twine. When the springs have been properly spaced and attached they must be tied. It is important to tie the springs in a way that they can act as a unit when complete. Jute twine is the most popular choice for securing the springs. There are two common ties that are used to fasten the springs to the frame and to each other.

Design of springs is important

Care needs to be taken when designing a spring for a particular application. As you don’t want it to be too hard to compress, as conversely, you wouldn’t want it to be too forgiving. Typically, the number of coils and or the wire diameter determines the strength of the spring in practical terms, but too many coils will hamper the function of it, and not allow ‘even’ compression. Too few coils and the spring will be in danger of completely collapsing and not returning to its original position on return.
