Haynes Roadster Bonnet

Way back when I started, the decision was made to make the chassis a 442. eg:

  • 4 inches longer
  • 4 inches wider
  • 2 inches taller

Having seen a couple sevenesque Kit Cars with higher bonnet lines the new plan is to make this a 440. – Well sort of.

I want the right side profile and I don’t want the nose to stick up in the air. See this blog.

Doing this will mean cutting up my chassis – again.

To try and explain my plans see these two side profiles:

Haynes Roadster Bonnet

In the bottom drawing I wanted to see if I could gain a smooth profile by lifting the nose cone slightly at the rear.

The bonnet was angled down towards the front by 25mm. I was unhappy with this, as there was still an obvious kink in the top line.

In the top drawing the nosecone has been left flat at a profile similar to the original seven. The bonnet was angled down towards the front by 60mm.

You can see that the top chassis rail now needs to be angled down towards the front. – at least it’ll add some extra triangulation.

Obviously, the Rover V8 plenum chamber for the EFi sticks through the bonnet. However, the top is not above the cowl. The plan is to use a bonnet scoop similar to a Westfield’s Seight. I don’t want a kit car where a hole has been cut around an protruding air filter. You wouldn’t see it of the latest Ford so why should I have it?

Kit Car Bonnet Height

The height of the bonnet was too high. So high, it would be hard to see over. Lowering the height of the bonnet was just an excuse to make the obligatory 'Brum Brum' noises. A replica Lotus 7 nosecone, sat on top of the chassis (McSorley 442 front end dimensions), simply sat ...

Plans and Drawings

When the design of this chassis is complete, full plans will be published. However, I started this design with a chassis bought on Fleabay. Complete ’Chassis Plans’ for the McSorley 442 can be downloaded in Acrobat format from : http://www.sevenesque.com/. − an excellent resource Courtesy of Jim McSorley Download Adobe ...

Kit Car Tube Chassis

This Haynes Roadster Kit Car Tube Chassis is a 44-0.2 4 inches wider 4 inches longer -0.2 inches less tall The gearbox tunnel hasn't quite ended up as I would have hoped. No doubt it will look better once the front section has been re-added. I think this exercise has proved to ...

Haynes Roadster - Rear Chassis

Now I have a flat table, progress on the chassis has been swift. In fact I surprise even myself. With only 4 hours work, Saturday and 7 hours Sunday the rear of the chassis has totally transformed. Armed with a bunch of tubes I'd cut and filed during the week, the chassis ...

Starting Again - Cutting It Up

It was decided that, although individual measurements often had small errors compared to the drawings, all these minor errors added up to huge errors. There were 27mm differences from one side of the chassis to the other and it had over 30mm of twist. Our goal was to have less ...

Chassis Type

Having quickly established that most pairs of measurements were different, the next task was to check all measurements against those published. In the process, establish exactly what type of chassis I´d purchased. The fact that measurements were different to those published would not be of major concern; as no ...

Chassis Collection

Having debated building a 'super seven' style car for decades, when a chassis came up on ebay with a reserve of only £0.99, temptation and curiosity took hold. The auction finished with only 3 bids at £56.55. Surely this was a bargain??!? A 550mile round trip would answer that. The unfortunate answer ...
