Upright vise and method of repairing a liquid paint displacement pump

An upright vise, comprising:

• a. a rigid hollow cylindrical column having an interior diameter, defining an interior space, and having an upper opening, and a lower opening;
• b. a rigid and flat first reinforcement piece with a central circular opening further defined by two diametrically opposed interior flats, the central circular opening being smaller than the lower opening of the cylindrical column, the reinforcement piece mounted beneath and centered about the lower opening of the cylindrical column, thereby creating an annular lip facing the interior space of the cylindrical column, and a flange extending away from the cylindrical column, the flange further comprising a first plurality of fastener openings evenly spaced around the central circular opening;
• c. an upper centering ring comprising an upper, wider, hollow cylinder having an interior diameter and defining an interior space, centrally mounted to a lower, narrower hollow cylinder of an equal interior diameter;
• d. a rigid platform having:
• i. a first circular opening and a plurality of fastener opening evenly spaced therearound and aligned with the first plurality of fastener openings;
• ii. a second circular opening reinforced with a second reinforcement piece and further defined by a central octagonal cutout larger than the second circular opening, and a second group of fastener openings evenly spaced around the octagonal cutout;
• iii. a third circular opening smaller than both the first circular opening and the second circular opening and a third group of fastener openings spaced therearound;
• and
• e. fasteners to fasten the flange to the platform.
