Wood working properties is very important in order to select wood for particular use. The study
was conducted to assess the working properties of five wood (main stem portion) species- lambu, aijun,
jhau, palmyra palm and acacia hybrid. The working properties were carried out in two different methods,
namely : machining and handtools. The effects of machining properties, such as- sawing, planing, shaping,
boring, mortising and turning were tested on these five wood species along with handtools test. The sawing
qualities of these wood were determined by manual feeding of logs to the saw blade. The evaluation of each
operation was based on frequency of occurrence of defect free samples. Finishing properties were evaluated
with the application of two different types of polishing materials, viz.: shellac and carpa as well. Each
sample was visually observed and classified based on five quality grades. The results indicated that acacia
excellent working performance in all properties. All rated excellent shaping result in handtools operation except palmyra palm. Palmyra palm yielded very poor results in shaping, boring, mortising and turning tests.
