501-25-45 Body Repairs - General Information 501-25-45 DESCRIPTION AND OPERATION Des Description FULSW ion 1 Center of dent 2 Spoon During hollow leveling, the dent is removed from the inside a using suitable panel beating tool and applying knocking or pressing movements. High spots around the edge of the dent area are flattened with blows from the aluminum or wooden headed hammer. The usual tools are for instance hammers of various designs, dollies, levering irons and various spoon irons. The correct choice of tool is made depending on the shape of the dent and the access which is possible. Dent removal using hammer and dolly Panel beating can only be performed using a hammer and dolly if access can be gained from the rear side. TO BE UPDATED LATER Des Description FULSW ion 1 Aluminum hammer 2 Box file The purpose of the dolly in this case is to transfer the force of the impacts from the hammer to the steel panel which is in between. As this is done, the deformed body panel is smoothed (dressed) and the tension fields in the body panel are removed. The favored tool for this repair process is the aluminum hammer and as opposite support the universal hand dolly. To rectify minor panel damage, the box file should be used as opposite support. Because of its serrated surface, the box file prevents normal stretching of the body panel which would otherwise occur. Heat-induced material shrinking Material shrinking, also called settling in, can be performed in a variety of ways depending on the extent of the damage and the access to the repair area. These repair processes differ depending on the type of heating and subsequent working of the heated surface. They sub-divide into two basic processes: ‡ Heating using a carbon electrode. ‡ Heating using the oxy-acetylene torch. In the carbon electrode process the working is done exclusively by warming. In this case the access to the repair position is only from the outside. TO BE UPDATED LATER Des Description FULSW ion 1 Carbon electrode
