When the design of this chassis is complete, full plans will be published. However, I started this design with a chassis bought on Fleabay. Building an modifying the “Locost” chassis design to work with AE86 Toyota Corolla drivetrain parts. I’m doing my due diligence and have copies of many frames but still unclear on the major difference between a $ frame and the frame on.

I have included some notes with the photos where appropriate. There are three drawing packages to choose from.
Scratchbuilt 1/10 scale Locost chassis
You can download a Caterham frame example from the Google Sketchup site. I haven’t detailed the build process in this section as the many photos on this site describe how it developed. Tue Jan 06, 3: Rear wheel drive Escorts are olcost hard to find due to their becoming a classic car in their own right, continued use in Rallying and increased interest from collectors.
The remainder is to be built from 1.
I’ve excluded them from the drawings because chqssis builder tends to customize the transmission tunnel to meet their needs cut-to-fit. I ignored the problems on the rear side, and continued with the transmission tunnel, built from 2. Paying respect to Mr.
In Australiakit cars must pass structural testing for certification for road use. If they are designed badly, they will have a low torsional stiffness, which will make for less than desirable road holding. Next were the skins, and I started with those at the bottom of the passenger compartment. The scale was chosen for convenience: As an example, a Lotus Seven has a torsional stiffness of around 1, Nm per degree.
There are some vendors manufacturing nosecones that are taller than the book design to provide even more height for the engine. Haynes and Tanner’s books, have good pictures of the Locost.
Chassis rigidity – FEA25 pages. Front lkcost is usually double wishbone with coil spring struts.
To get a taste of classic tubular chassis design, I decided to build a Locost chassis in plastic, using the Ron Champion book. Martin Aveyard balsa frame for a car of his own design, and the finished balsa frame.
The rear of the Locost is of course “inspired by” the Lotus 7. I used an old tin that had thickened and needed thinning, and a fresh tin that was really thin.
Page 1 of 2. I wanted to preserve some of the floppiness of the sheet metal, hence this thin gauge. Most car chassis are ‘space frames’ which are usually two truss sides connected with a collection of of transverse tubes. I find the British sense of humor so enjoyable – but what do they think of yanks?

I later enlarged the holes in all brackets, to make them look more realistic. Tue Jan 06, Ever since doing a design exercise involving a truss-frame aircraft fuselage, I have a deep interest in frame structures. I’m especially fascinated with three-dimensional truss structures for car chassis design, which so far I haven’t found a real example of.
You still need to finish the transmission tunnel, add the supension brackets, transmission mounts, motor mounts, clean it, paint it, and put on the aluminium An evening of work finished the chassis. Therefore the buffing did not go easy, and especially on the delicate 0.
Scratchbuilt 1/10 scale Locost chassis
For readers with Ron Champion’s book: Catherham Vs Locost Posted: It definitely has the right effect, but it’s also very vulnerable, and I had to install repair patches in locst few locations after breaking the skins.
The subject car differs most significantly from the original in that it has an independent rear suspension. A Locost is a home-built car. I cut away the paneling below the prop shaft, whereas the book doesn’t. Tue Jan 06, 1: The increased height goes through the horizontal portion of the chassis forward of the dashboard to balance the over all design and accommodate taller engines.
Learning much more than the books provided. A standard book nosecone leaves a 5″ gap along the bottom of this super-sized chassis, but the width is spot-on. For modern high-performance cars, 30, Nm per degree is the target. Various projects have analyzed the strength of the Locost Chassis under Finite Element Analysis for interest’s sake.
And they behaved very different, the latter drying very, very fast at summer temperatures. Probably missed this someplace in the forum’s but tried.
It is assumed that donor parts and personal choice will dictate the final llocost of the transmission tunnel and suspension. I bought the edition, which is slightly revised.
Locost Builder Jim McSorley revised the Ron Champion design in order to accommodate wider engines, rear axles, and seats. The Caterham is one of the very few clubman frames that has a creditable FEA analysis performed on it, which resulted locosg a design that has three different size tubes and 5 different gages.
Thats probably the biggest part of your due dilligence It seems the dimensions of the rear section are not correct. Next the ‘sheet metal’ of the transmission tunnel, the rear uprights, the footwell front, the sides of the car, the top of the footwell, and the nose bottom panel were added, in that order. Does anyone have pictures of the Caterham’s for a side by side comparison?
I know that some later Caterhams have an aluminum honeycomb floor.
