The increase use of wood for furniture design of various forms has called the need for an effective means of cutting wood of various types into required dimensions. An improved wood sawing machine was developed using locally available materials in this research. A detail material selection process was done to ensure that the proper materials were used for the production of the machine. Basically, two major areas of improvement were; introduction of guard system to the upper part of the blade that protrudes towards the end and hopper tray for the lower part. The performance evaluation of the developed machine was carried out with wood of various dimensions and types. The result revealed that the machine cut a hard wood of 50.8 mm thickness in 141.5 seconds and soft wood of 50.8 mm thickness in 128.5 seconds. The developed machine is safe to use, reduces the stress of cutting wood manually and has no environmental effect as a result of wood dust exposure. The estimated cost of production of the machine was ninety- thousand naira (#90,000) only which was approximately ($300).
