WORKING QUALITIES OF SOME INDIAN TIMBERS - PART - X

Abstract

This paper is in continuation of earlier papers on systematic evaluation on working qualities of Indian timbers in which results of working qualities of seven more species namely Abies pindrow, Acacia tortilis, Leucaena leucocephala, Piciea smithiana, Paulownia species, Salix alba and Ulmus wallichiana have been reported after testing them under six major wood working operations - Planing, Sanding, Turning, Shaping, Boring and Mortizing. The working quality index based on quality of worked surface and ease of working for each species are reported along with the results of Tectona grandis for comparison. These results indicate that overall performance of Paulownia species and Ulmus wallichiana is better than Teak where as Acacia tortilis, Leucaena leucocephala and Piciea smithiana are comparable to Teak. These are easy to very easy to work with hand and machine tools.
