| dc.description | The study was conducted in two phases. Phase I documented the timber species and timber management practices in furniture workshops while phase II studied selected physical and mechanical properties of the timber species. A checklist was used to document the common timber species, their grades, moisture contents (MC) and related management practices. Using ASTM: 2003 standard wood testing procedures, Basic Density (BD), machining properties,Nail Holding Capacity (NHC) and Cleavage Resistance (CR) were assessed. Albizia coriaria,Markhamia lutea and Chrysophyllum albidum were the commonest species while Khaya spp,Melicia excelsa and Olea spp were among the scarce species in the furniture workshops. Sixty nine percent of the furniture workshops lacked timber stores, whereas only 3% had the right timber stacks. Majority (95%) of the carpenters in the furniture workshops did not season timber and hence the moisture content of the timber ranged from 31 to 35%. Majority carpenters (49%) exposed their finished products to the open weather conditions, hence prone to deterioration. The commonest waste was planer shavings that were not utilised effectively. Most carpenters (97%) did not follow the formal guidelines to grade timber visually. However, on assessment, the commonest visual grade was the third grade hence affecting the quality of products they made. The BD of A. coriaria, M. lutea and C. albidum at 13% moisture content were 764, 684 and 712 kgm-3 respectively. C. albidum, M. lutea and A. coriaria had excellent(90-100%), good (70-89%) and poor (30-49%) machining properties respectively at 14% MC. The CR of A. coriaria, M. lutea and C. albidum at 13% MC were 50, 57 and 49 Nmm-1 respectively. M. lutea had the highest NHC followed by A. coriaria and C. albidum. Tangential NHC was highest and Axial NHC lowest for all the three species. M. lutea and C. albidum are fit for use as decorative furniture members while A. coriaria is fit for structural strength in making furniture. The small scale furniture workshops should formalise their operations by getting registered so as to improve their efficiency and ease monitoring by concerned authorities. Further research on physical, working and strength properties of the documented species should behttp://dspace3.mak.ac.ug/xmlui/handle/20.500.12282/171/submit/8414141d5e4a383c23517347291d23137653104a.continue undertaken to improve their utilisation. | |
