Outdoor recreation is always more fun with a dune buggy. This type of vehicle has an open chassis and wide tires that make it suitable for sandy terrain. It is usually found on beaches and desserts where its geometry allows excellent navigation. People can avail of ready-made models or have their own designs built into reality. Custom dune buggies can be made in different ways but the objectives are largely the same. The primary goal is to boost the power-to-weight ratio as much as possible. Safety features and conveniences can be added as well. Some buggies are designed to tackle a mixture of terrain and not just soft sand.
In this approach, everything starts with an existing car which is then modified to the customer's wishes. Lots of early buggies were made from the legendary Volkswagen Beetle and the result was affectionately called The Bug. This is precisely why this sort of vehicle is now called a buggy. The Beetle is ideal for a number of reasons including the rear engine positioning which shifts the weight towards the back. This improves traction for rear-driven wheels. Air cooling and the lack of a radiator make modifications simple. Possible points of failure are eliminated. Beetles are also low-cost options with easy to access spare parts. The modified shell can be made using a press brake machine. The metals and materials of these shells can differ depending on your desired design. Heavier metals tend to be stronger but reduce speed, so it can be a challenge to find the right weight to strength ratio.
Building from Scratch
In this method, a new vehicle frame is constructed entirely from scratch. Steel tubing is used for this purpose. It is bent into form and welded to achieve the exact specifications required. By opting for this method, fabricators are able to achieve a high degree of freedom throughout the process. Every single part can be changed if desired. For instance, the suspension may be improved for greater riding comfort and a roll cage can be included for safety purposes. This type is often called a sandrail buggy due to the rail framing. They typically have their engine behind the driver's seat. The can be as small or as large as the customer needs.
A Hybrid Approach
Sometimes it is best to mix the two extreme approaches to build a buggy more efficiently. By using an existing vehicle as base, much of the preliminary work can be avoided and the project can be completed much earlier than usual. At the same time, certain important modification can be added in as needed. Fabricators often use damaged vehicles for this purpose. These may be units that have been worn out by age, abuse or accidents. There will always be salvageable parts even in the most heavily damaged cars. Also, they are plenty of owners who discard theirs even for minor bumps and bruises.
Choosing a Fabricator
Find a fabricator who specialises in this type of vehicle construction. Ask for samples of their previous projects. Pay their shop a visit if you can to see the items for yourself. See if they have a complete line equipment such as a press brake machine or if they outsource jobs to others.
