Free Technical Kart Drawings (FIA)

CIA LogoThe CIA (Commission Internationale de Karting) is the specialised Karting commission of the FIA, the governing body of world Motor Sport. The CIA oversees Karting safety in conjunction with the FIA and with a Research Group exclusively dedicated to Karting.

The CIA publish Technical Regulations for Karting, which includes detailed Drawings and specifications. In their most recent publication (2007), detailed drawings showing measurements and designs for Kart chassis are included.

CIA Sample Kart Chassis Technical Drawing

The drawing above shows actual sizes (metric also!!) of Karts and provide an excellent guide to building a Kart complete to regulation!! Many people, including myself develop free kart plans, and overlook the wealth of information and diagrams offered by Karting Authorities such as the CIA.

Plans for a Wooden Push Cart with Steering Wheel

Do you want an easier wooden go-cart to make? Want a more fun and friendly cart to drive, with a Steering wheel? People have emailed in asking these questions, so I dug out an old set of cart plans and revamped them. Below is an image of the wooden cart you can build. The plans for this are all finished and available now.

A sample page of the plans can be seen below. To download and obtain all 10 detailed Drawings, head to the kartbuilding.net website.

Book Review: Build Your Own Off-Road Buggy for as Little as £100

Overview

I recently bought the book “Build Your Own Off-Road Buggy for as Little as £100” for £8 including postage and shipping from amazon. Overall it was an enjoyable read. I had hoped for more in-depth discussion and details on certain aspects of the kart. The book provided details on building one particular design but didn’t explain why or how to a lot of the details and measurements chosen. That could well be a good thing for a person making their first kart (or buggy as its called). For you folk working in dollars, 100 UK Pounds = 155 Dollars. After reading the book, and looking at the parts the author used (e.g. the wheels and bearings etc.), it would be a tight stretch to get the whole kart built for £100 or $155.

Audience

The book is geared towards adults helping them build a kart (buggy). The person building the kart would want a good level of DIY skills. It is also expected that a person obtain a welder either by buying a new or second-hand welder, or hiring one. It was difficult following the text and images in some places, trying to fully understand what is been described and I found myself reading paragraphs three and four times.

Relevance

The book was highly relevant to a person confident with DIY skills in building an engine powered go-kart. While it did not explain the “why” of certain angles and details, it provided enough dimensions, that if all followed correctly would work.
I did feel that some of the areas were sparse and outside the scope of home workshop capability. One example of this is where a “differential flange” from a ford car was used and modified to act as a hub for mounting the rear wheels. Another flange was then used for the sprocket carrier and brake disc carrier. While this in fact is a very innovative idea and one which I had not considered, modifying one of these differential flanges would require a metalwork lathe and a lot of work. (Of course the option of buying new or old hubs from a go-kart is suggested).


The book which has 90 pages has just enough information and diagrams to build the standard kart. It is clear that the author has made a few of the karts themselves. The author also got a friend to try following the book and building the same kart.
I do think a simpler design could have been chosen. The kart chassis has 3 members requiring a pipe bender. I also think the pedal design is poor. Using 5mm flat steel bent into an L shape would in my opinion be insufficient and would bend easily (as the pivot is just a hole in the 5mm steel bar). I prefer using 20mm pipe for the pedals.

Chapters

  1. Skills required
  2. Tools, equipment and workshop safety
  3. Sourcing what you need
  4. Making the frame
  5. Front axle and steering
  6. The engine and gearbox
  7. Drivetrain and brake
  8. Controls and starting devices
  9. Finishing and final build
  10. Using your Buggy

Good Points

  • Information on different places to source parts, materials and engineering services were outlined.
  • Information on kart safety, safety when building the kart, best places to drive the kart is provided.
  • Loads of information on welding, different types of welding and background information on Gas Welding is detailed.

Poor Points

  • No explanation of certain areas (such as camber, castor and ackermann angles) of building the part is outlined.
  • No set of complete plans, but rather all details were spread out throughout the book.
  • To build the kart as shown, you would need a pipe bender and metalwork lathe (to machine the hubs and sprocket carrier)
  • While “alternative solutions” were provided for example track rod ends, no measurements or details of these were given.

Conclusion

I have previously purchased complete sets of plans for off-road karts and buggies. While I found this book enjoyable, easy to read and informative, I think it didn’t explain enough of the details. I would have also liked to see 15 pages with complete drawings of all components together. I like to be able to print the 15-20 pages showing the complete set of plans showing all the dimensions together. However for £8 it is certainly cheap and well worth a read and will help you make your first go-kart with a motorbike engine.

Plans for a Lawnmower Powered Go-Kart – Finished

The plans for the wooden go-kart powered by a lawnmower engine are finally finished. Below is a collage showing thumbnail images of the 21 drawings in the set of comprehensive plans for this go-kart. Full parts lists (shopping lists) and Tools required for this kart have all been documented. There still is no costing / overall price for each part done yet, but when it is it will be included. Head on over to the main kartbuilding website to see the completed set of plans.

Plans for a Wooden Go-Kart powered by a Lawnmower Engine

I’ve been meaning to update the Basic Wooden Kart plans to include provision for using a Lawnmower Engine to drive the Go-Kart. Quite a lot of people have being asking for the various details for this Wooden Go-Kart, and instead of doing bits and pieces, I decided to model the entire Go-Kart. Key aspects of this kart include:

  • Lawnmower Engine used to power the go-kart.
  • A Clutch system to allow the engine to idle.
  • Using brakes of a bicycle.

I’ve just finished all the 3D Modelling of the kart, and will be doing the Plans and 2D Drawings very soon. Meanwhile below is a taster of what the Lawnmower Engine powered Go-Kart looks like. I did have old plans for this wooden kart, however they were very old, and done in 2D CAD.

If you want to view the Kart in all it’s 3D glory (including details on the throttle and clutch system), click to download the 3DVia Viewer Package of the Wooden Kart (3 MB).

 

 

Stay tuned to www.kartbuilding.net where I will be publishing the complete set of plans for this engine powered kart. I will also be making some videos showing the assembly of the kart, the key components and the operation of the kart. Following the tips and feedback of many people who contacted me at , I will be making a complete Bill of Materials / Shopping List of part and components, so that anyone will be able to build this kart. If you have any requests on what is included in the 2D printable plans, drop me an email.

SolidWorks CAD Drawing of a Tony Kart Chassis

ABout Tony Kart

Tony Kart produces high quality racing kart chassis. A catalogue of their kart chassis can be found on their website. A particular chassis model, a Tony Kart Extreme ’97, was modelled using SolidWorks, and is available for download. Below is an overview of the chassis, in isometric and in a plan view.

Overview of Chassis in SolidWorks

This chassis is modelled perfectly in SolidWorks, with each member as an individual part and fully in-context. With the complete assembly and part files, it would be very easy to create 2d drawings of the chassis. The chassis is full size, so no scaling would have to be carried out.
Perhaps in the future the author will complete a fully dimensioned chassis using SolidWorks. Please contact the author if you have any queries etc. regarding this.

Download SolidWorks Files

The SolidWorks assembly file can be downloaded from its original location here, along with some other CAD drawings also. A backup local copy of the SolidWorks chassis is also available.

eDrawings Download of the Chassis

In case you don’t have a copy of SolidWorks to open and measure the components, the eDrawings viewer can be used to open the chassis, measure each component, and create a section view through the chassis. The chassis opened in eDrawings can be seen below:

Note: the eDrawings download of the chassis contains a self executable viewer application.

Conclusion

Hopefully the detailed professional chassis design will give you ideas on how to design and create your own chassis. An idea of the size of the chassis design can also be obtained using the eDrawing. Best of Luck!
