Power Mechanics

I am not currently teaching Power Mechanics.

This course is intended as an introduction to engines and their application. Students will study the components and operation of both two and four stroke engines, and will disassemble, reassemble and start both engines. Students have in past rebuilt their own lawnmower, snowmobile and chainsaw engines.

A second unit in this course is the design, construction and competition of a CO2 Dragster.

The course is divided into (but is not limited to) the following topics (time permitting):

  • Shop Orientation
  • Engine Systems
  • Fuel Systems
  • Ignition Systems
  • Lubrication Systems
  • Cooling Systems
  • Engine Performance
  • Troubleshooting, Service and Maintenance
  • Engine Service
  • Engine Applications
  • CO2 Dragsters
  • Aerodynamics
  • Brainstorming
  • Sketching
  • Working (Orthographic) Drawings
  • Cutting
  • Shaping
  • Sanding
  • Painting

CO2 Dragsters


  • Practical Shop Work – 50%
  • Theory Assignments and Quizzes – 50%

The Practical Shop Work Mark is based on productivity, work habits, safety and cleanup while working on assigned projects, or assigned labs. The student will fill out a Technical Activity Report of work completed at the end of each period which will be assessed a mark out of 5, per day. A variety of labs will be assigned.

All students are expected to treat others with respect.

Absences do not excuse assignments.

This is an Educational Facility not a Repair Facility, and as such, no “outside work” or “for money” work is to be done. Mr. Wellwood will not “do the work” for you, be it using the tools, using the service manuals, or troubleshooting. YOU are the motivational force behind your success in this course. You give me your commitment, I will give you my help.
