Awesome, I've joined the group! Are you sure you want to use old-style diffs? I think new ones would save space, adding more room for wider suspension while keeping the wheelbase the same.

[Ape Fight]

Great.

The chassis uses some older parts, as it's not an unlimited parts build.

The suspension is not one of the modules required in this first version of the project - the platform is a completed module.

Just joined,do you want to take some detailed pictures of the "platform" for me to transfer to cad?

Quick question: Is it possible to not have bump steer when using 6.5L suspension arms? I have tried everything and could not avoid it.

It is not possible, because the steering links are 6L . It is only possible with the newer 6L suspension arms.

[Junpei]

Aargh, I can't believe I bought 6.5L instead of 6L.. Now I have 8 of them, all they're good for is live axles...

Hey. Yes, that would be awesome. I can't take new photos until next week, but I will do so as soon as I can and upload them to Flickr. It's quite simple apart from the gearbox maybe.

[Alasdair Ryan]

Should the gear box not be a separate part so that people can change the transmission?

Should the gear box not be a separate part so that people can change the transmission?

I've built the gearbox already, because it's (I think) the most accommodating gearbox design yet, it's completely flat and thus allows for a wide range of interior options. It is though, easily removable, so another gearbox could be added if a designer chose to build this car themselves.

As I'm building a the complete car, using the crowdsourced components built by other builders for bodywork and interior, I wanted my own gearbox in it. However, if anyone wanted to recreate the chassis without my design they could insert their own gearbox, or engine, or bodywork....

This is a great idea! I would love to get involved in any aspect of it, please contact me at ben.hunt.62@gmail.com

Welcome to Eurobricks, Ben! Thanks for joining the project, too.

Try angling the steering tie rods upwards and not parallel to the arms. Just watch Nicjasno's video on toe in, toe out, and bump steer.

Welcome Ben! To get involved please join either the MOCpages or Flickr groups linked in the post above

I tried that, but that just shortens the steering link to about 5.5L limits the suspension travel and creates more bump steer. Plus, non-parallel steering links cause all kinds of problems. I don't think there's any way to align the links with the odd-length arms.

The component requirements are up. As an example, the Bodywork:

Our Crowdsourced Supercar requires several components to be engineered in order to complete it. These can be designed by any individual or team on either MOCpages or Flickr. Each component has a number of design requirements; Essential, Desirable and Nice-to-Haves. The design that best meets these will be selected and added to the Supercar.

Component No.3: Bodywork (the big one!)

Essential Requirements:

- Dimensions of the platform followed:

https://www.flickr.c...07/11160347656/

- A GT/Sports/2+2 design

- Allowance for a minimum of one stud/brick of suspension travel

- Allowance for 'swing' of front wheels turning, 2 studs either side of the front wheel).

Desirable Requirements:

- Allowance for more than one stud/brick of suspension travel

- Retention of existing platform perimeter (the black bricks at the edge of the platform and the front and rear)

- Capacity for a 2+2 interior

- Sufficient front overhang for a PF Medium motor to be placed ahead of the steering rack.

- Minimal distance between the wheel arches and the outer edges of the tyres

- Low or nil usage of rare or expensive parts

- Low weight

Nice-to-Haves:

- Ability to add additional cooling to the engine may depending upon the chosen engine

- Ability to include a variety of door and apatite designs (e.g gull-wing, scissor or suicide doors, as part of component 6)

For further information please see the platform dimensions here:

Notes:

- You are in competition with any other designers or teams also building this component. Only one design will be selected for use in the Supercar, unless a collaboration is deemed to yield the best results. In this case two designers or teams may be requested to work together.

- In order for your design to be considered it must meet all of the Essential Requirements. The more Desirable Requirements and Nice-to-Haves that you meet the higher your score will be, and the greater your chance of success.

- The winning designer or Team will be credited in the final version of the first ever Crowdsourced Car.

- Please note it is highly unlikely that your design will be perfect at the first attempt. Just like the engineering process of a real car please expect the need to refine your design, and for possible changes to the requirements should other components have unforeseen effects on this one.

- Drawings and test prototypes are recommended and can be uploaded to the Flickr group here:

http://www.flickr.co...ps/2401897@N24/

- In the event of a tie on points between two or more designs, the other Crowdsourcing members not involved in this component may state their preferred choice and why.

Good luck!

Joined the group, great idea, but I won't do any bodywork at all

I thought the body work would be the one people would want to build but it seems everyone's nervous of it!

[Mikuri]

Is there a way we can have instructions? Would be way easier ~

Only if someone wants to make them! I can take more photos of the chassis now if someone does possess instruction-making skills

[Mikuri]

That would be awesome ;o; Or even more pictures to try to recreate it.

[kevman]

Aargh, I can't believe I bought 6.5L instead of 6L.. Now I have 8 of them, all they're good for is live axles...

I made the same silly mistake. They weren't cheap either....ARGH!

[Ape Fight]

I've been a bit lazy and so I've not taken the chassis apart for photos, but there are a few more pictures on Flickr now, which (I think) are all that would be needed if you wanted to recreate the chassis yourself - as it's a very simply constructed design.
