Show EASY MATTER TO FIX BROKEN CAR Missouri Driver Strikes Stump and Tears Off Drain Plug From Crank Case. SUCCESSFUL REPAIR IS MADE Plaster of Paris Mold Used to Caet Babbitt Cover Which Was Bolted in Place and Oil Is Prevented From Leaking. While touring over some rough country I struck a stump, as Illustrated Illus-trated In the upper left-hand sketch, which tore the drain plug and Its seat from the base of the crank case. A Jagged and apparently irreparable hole was left. After being towed home, I succeeded in making the repair Indicated Indi-cated in the sketches. A shoe-polish box was filled with plaster of paris nnd pushed up against the case, as shown. When the plaster of paris had set it was removed. This gave me a perfect form of the hole. The surface of the plaster form was then oiled, a paper mold made around It, and filled with soft plaster. When this plaster had set, the two forms tf-?J "et w Molds of Plaster of Pans and Paper Were Used to Cast a Babbitt Cover Which Was Bolted In Place Where the Crank.Case Plug Had Been Torn Out. were separated and the last-made one was used as bottom for a mold to pour molten babbitt Into as Illustrated. A suitable bolt and crossbar, as shown, were first placed In the mold. The finished product was a perfectly shaped cover, which, by means of the bolt and crossbar, was fastened securely se-curely over the hole. Shellac was applied ap-plied to the surfaces to form a packing. pack-ing. The repair was thoroughly successful suc-cessful and In the several months that it hns been In use It has not let a drop of oil escape. The plug is readily read-ily removable for draining the motor.
