Abstract

Experiments were conducted to develop a cutter joint between duraluminum tub and steel cutter to make a replacement of the cutter possible under field conditions. A threaded bushing provides a simple, positive, and reliable connection but usually requires a special wrench for removal. A soldered joint using aluminum solder produces greater strength and can easily be replaced by heat application. Soldering of couplings is recommended. Two models of a wrench designed to increase leverage and eliminate the probability of the pin being forced out of the hole were tested and found satisfactory. Their overall length is 8.5 in. and will not slip off the joint when in use. Information on aluminum solder and source of supply are included.
