A rotating window mounted directly to one side of a stationary, viewing window or panel without the need to cut a hole in the stationary window. The rotating window faces toward the working or weather-exposed area and slings off any water or other debris that contacts the rotating window to maintain clear visibility through the stationary window. The rotating window further comprises a means for drawing air through the area in between the rotating window and the viewing window so that moisture does not collect on and fog up either window.

A modular clamping system for fixturing workpieces with respect to a numerically controlled drilling and boring machine or the like includes a pair of soft jaw blocks which may be variably spaced with respect to one another in fixed positions to hold the workpiece therebetween. A vice assembly preferably holds the soft jaw blocks in a fixed position during use by way of several vertical and horizontal alignment mechanisms. Cavities to hold the workpieces in place are machined in the soft jaw blocks by the NC machine prior to each job to accurately reference the workpiece with respect to the NC machine.
