A holder is described for temporarily mounting a ski on a work surface for permitting the ski to be tuned or otherwise routinely maintained by filing the ski edges and bottoms and for coating the ski bottoms etc. Each holder has a threaded clamp for mounting it on a work table or other convenient surface and has a pivotally mounted vacuum ski engaging device at its top for removably engaging the ski. Two of these holders firmly position a ski on the work surface for the ski tuning operation.
