METALWORK 10Pocket Saw Project

INTRODUCTION

Students will design and build a folding pocket saw

Project is intended to develop a number of skill sets

Design process will allow students to create a customized saw blade intended for anything from camping to fine woodworking

Learning Outcomes

• Steel folding and shaping techniques

• Practical and aesthetic design

• Material Science (high carbon spring steel vs. mild steel etc).

• Heat treatment techniques

• Riveting Techniques.

• Saw blade design and tooth set.

MARKING RUBRIC

Conformity to IRP

• Background knowledge and creative/critical thinking skills.

• characteristics of metals, strength, ease of use, application

• Relating understanding of metalwork to personal, economic, and societal considerations

• Potential uses such as a drywall hole saw, buck knife, mini-hack saw.

• Economical use of materials, recycling scrap metal from places like old leaf springs.
