PROCEDURE:

Place the given irregular shaped metallic piece between the jaws of Bench Vice .By the help of given file make all the four sides perfectly smooth and at 90 degree to each other. Use Try square for this purpose. Rub/Clean the top and bottom side of the metallic piece using the same. Now rub the wet chalk on one of the flattened side of the metallic piece. By using Scriber mark the lines on the metallic piece so that cutting may become easier. Use punches to mark spots on the lines to simplify our task. Then make holes at the center of plate using a drill machine. Then perform internal and external threading. External threading on the given

cylindrical job and internal threading in the drilled holes. Then the cylindrical job was fit up in hole of metal plate.
