Monday March 5th, 2007. | 1TG - Design & Build of the One Tonne Guerilla

The current project status is that what I would describe as the major mechanical design is completed. That is I now know:

Where the engine & gearbox are going to be located.
Where the driver and passenger will be housed.
Where the wheels are going to be located.
Where the suspension mounting points and dampers are going to be located.
Where the steering rack will be located.

And most importantly of all how to tie all of this together with a structure that is as stiff as possible and has sufficient strength and is not excessively heavy.

In short I’m at the point where I feel confident enough in the design to go start making it.

The little list above took over a year of thought to resolve to this point, what I’ve now got is a design for the chassis frame that weighs ~125Kg for the steel tube framework including the roll frame and has a stiffness in excess of 15Kn Per degree which I think is sufficient.

So the next thing to be done is to get on with fabricating the frame.

I have a number of tubes that require bending as part of the design, not having the equipment to do this I’m now in the process of tracking down a company who’ll do this for a fair price.
