Bal-tec™ Home Around The Corner
Around the corner is a rather unique kinematic component that allows for wide-angle positioning of the portable platform. Using these kinematic devices the platform can literally go to any angle from less than horizontal to more than vertical.
These components are available in a micro grain stainless steel that has a minimum hardness of 58 HRC or in tungsten carbide, which is the stiffest, hardest commercially available material. Tungsten carbide has a Young's modulus of elasticity of 98,000,000 P.S.I. and a hardness of 91 HRA.
An optional design for this component is to thread the pinhole, but it is usually very awkward to machine the intricate details to bring a cap screw through the platform at a 45 degree angle. In addition, Electrical Discharge Machining ( EDM ) the thread in these hard materials adds a considerable cost to such components.
