Indigenous Substitutes for "Lignum Vitae" for Making Stern Bearings for Fishing Boats

Abstract

Difficulties are very often encountered in selecting proper
material for making stern bearings for fishing boats. Conventional
materials such as white metal, bronze etc. wear out too fast also
causing considerable wear to the propeller shaft. Lignumvitae, a
natural wood commonly used for this purpose, is not available on a
commercial scale in our country. Results of trials carried out to
find out suitable substitutes for lignum-vitae from among indigenous
timbers are presented in this paper.
