Hiy guys, thanks for warm welcome and positive responses.

Regarding the possible errors in scaling up, you do have to hope that the master pattern maker for the model got it right.

That said, we do have the benefit of technology. We actually approached this from two directions. The guy who did the Inventor work for me (I learnt to draw when we still used pencils, ink and razor blades) first tried to develop the body by overlaying computer generated splines and curves on a 3D model devleoped from scanned in 2D plan and side views. You quickly see that the body curves and blends follow natural lines. When this exercize was partially complete we measured the model, and than added in the plotted points. We were pleased to see that they fell almost exactly onto the developed predicted lines. So we combined these techniques to get it looking right. By now we had looked at hundreds or photo's of original T70's and even those seem to vary from car to car.

They also say that if it looks right, it is right, so I am hoping that it will work out well. I am not going to pretend that the panels I make will fit a real T70, but that is not the intention. When I started my project I did not have a particular body in mind, I just wanted to build a car. But you see some home built unique body cars that just don't look great, and I didn't want to do all this work (building a car) and not have it look good. So I decided to follow a car that is accepted as looking good to everyone.

So we will see what happens once the buck starts to come together. I have been help up by some domestic projects but these will be finished soon. I can't wait to get into clipping the parts together!

Cheers
