Abstract
A fracturing tool for connecting rods has a first and second body prepared from material with a grain direction, each body having a semi-cylindrical protuberance with an axis substantially parallel with the grain of the material. The two protuberances together define a substantially cylindrical mandrel which can be placed within the large bore of a connecting rod which is to be cracked. The bodies are mounted so that one of them is slidable toward and away from the other in a direction perpendicular to the axis of the mandrel. The method of making the tool includes mounting the bodies on a rotary table having an axis of rotation coaxial with that of the mandrel. The rotary table rotates while a grinding wheel finish grinds the mandrel surface.
