Legs, Legs, Legs! (Betty Grable, Eat Your Heart Out!)
Once again, welcome to the Techies Corner. In the last few articles we have talked about platforms, the types of platforms, special platforms and how to brace them. This month we will look at legs, legs of many types and how to make them and what their pros and cons are.
Legs fall into two major types, those that support by friction pressure and/or the shear strength of fasteners, called the standard leg, and those that support by direct, in-line compression, called compression legs. I am sure that there will be several types of legs that I will miss or forget. Please contact me directly and I will make space for those and include them in next months article.The basic difference between the two types of legs is manner in which they support their loads. A friction/shear leg relies on the tightness of the fasteners, the sideways friction generated between the leg and the platform and the sheer strength of the chosen fastener. The compression leg relies on the direct in line compression of the leg material.
