Tell us about yourself:“I'm a computer programmer by day and a metal fabricator by night. I enjoy working with my hands building things and maintaining my vehicles.”
One look and there’s no doubt that David put a heck of a lot of thought in the design of his dune buggy project. If he’s not at our Ottawa location looking for a tool or piece of equipment, he’s in his shop building or restoring something!
Thanks, David, for sharing your dune buggy with us! See David’s dune buggy in action: http://www.youtube.com/watch?v=P-hNLF_naXY
What is it? A single passenger off-road vehicle with 4 wheel independent suspension, 250cc engine, forward high/low & reverse, front & rear disk brakes, a 1,500 lb winch, and a 3-point safety belt.
What is the main power source for your project? (e.g. electric motor, gas engine etc.) I used a 1982 Yamaha SR250 single cylinder gas engine.
What components are used to perform the work for your project? (e.g. hydraulic cylinder(s), hydraulic motor(s), sprockets, pulleys etc.) Rack & pinion steering. Push pull cable for shifting the transmission. Hydraulic master/slave cylinder for clutch actuation. Hydraulic brakes.
What design/build challenges were overcome? The rear drivetrain was challenging because of the tight fit with the U-Joint, suspension arm pivots, axle bearings, and gear-box. I used 3D software to model the components in order to check clearances before I started to build.
If you had to build it again, what would you do differently? Put in a bigger engine!
