Abstract

This article describes reshaping the two holes of a slider guide to minimize binding of any sliding member moving along two parallel shafts. Each hole is reshaped in one direction only. One hole will maintain horizontal reference, while the other maintains vertical reference for the slider. This method allows accurate, low-friction sliding without ball bearings. The problem of binding occurs when guide rods are not properly aligned. Even when guide rods and slider conditions are ideal, binding can occur when slider thickness allows tipping relative to the guide rods and the leading and trailing edges of a slider hole act together to seize the guide rod (Fig. 2). Fig. 1 shows the slider member 10 positioned on the guide rods 16. These guide rods must be substantially parallel to help prevent binding.
