Chassis Plans The chassis plans on this site are based on the original Locost design presented in Ron Champion's book. The plans are not complete, but they should provide you with a very good (and very accurate) starting point. You still need a transmission tunnel and certain triangulating members that are not shown. Be sure to refer to the book for these structurally critical pieces. I've excluded them from the drawings because each builder tends to customize the transmission tunnel to meet their needs (cut-to-fit). The missing triangulating members were simply too difficult to model with the computer.
Book Chassis - Plans, BOM/Cut list, IGES model. A more detailed and more accurate version of the design presented in Ron Champion's book, 'Build Your Own Sports Car For As Little As £250 - And Race It!' There is also an Excel spreadsheet containing a bill of materials for the book chassis. The chassis plans on this site are based on the original Locost design presented in Ron Champion's book. Champion's book, 'Build Your Own Sports Car. I was off by 4.5 inches!!!

I only ask that you refer to this website () as a favor in kind. Notes regarding Unit of Measure: The CAD models were developed using standard measures based on 1' and 3/4' rectangular tubing. The drawings show secondary dimensions based on an automatic conversion from standard to metric. Binary code converter. As such, each measurement that depends on the width of the tubing as a point of reference will be off by at least.4mm (25mm vs. This small difference is compounded during the assembly process when working with computer software.
In the real world however, the overall effect of this discrepancy is negligible given the accuracy of most shop tools (or lack thereof). Download Hints 1) You may need to install Adobe Acrobat Reader to view the drawing files. 2) PC users: You can save the files to your computer with a right-mouse click on the link and then choose 'Save Target As.' Download the Drawings There are three drawing packages to choose from. All of them are based on the original Locost design, including the front end design to accomodate a standard nosecone and the suspension design found in 'The Book.' I do not have any plans for the Locost suspension since the book provides a lot of detail and your donor parts may differ greatly.
