Hacksaw

grabcad

This tool is a unique "Hacksaw" featuring a rigid metal frame made from flat steel and a wooden handle. The frame comprises a steel band with dimensions of 10mm in width and 5mm in thickness, which is later bent, partially machined, and anodized. A hexagon nut threaded into the grip facilitates tensioning of the saw blade when connected to a threaded tensioning bolt by rotating the handle clockwise. The wooden grip has a bushing pressed onto its cylindrical surface or the six flat surfaces of the hexagon nut. Metric threads (M8 x 1.25) are modeled with theoretical values, without clearance. In the main assembly, the metal saw frame and blade are shown in an untensioned state. The maximum tensioning stroke is approximately 4.8mm as per the 3D model. Unfortunately, the saw blade lacks offset teeth due to modeling limitations in PTC Creo Parametric 2.0; any assistance in modeling them would be appreciated. The model can be accessed in formats such as STEP (.stp), native files (.prt) and (.asm) in a zipped folder for PTC Creo Parametric 2.0 users.
