Now I had a base for the tunnel frame, I could make a start on the rest of the rails for this side. The bottom rail was trial fitted before having it's closing piece fitted to the rear end. This will close the tube off and also give any diff cradle something to bolt to.
With that in place, the next section along could be made up and welded in place.
The top rail was next. I was in two minds over if I should make this rail from round or square tube. Round would give a nicer edge/curve to the top panel, but square is easier. I also have square tube, and the only round I have is expensive CDS, which I will be using for the wishbones. So square won out in the end.
That's it for now, as that took a while to get right although the top rail is fully welded in the cabin. I can't rush this bit, as once the rails are in, cutting them out will be quite a task. The next steps are the two remaining vertical tubes, and then the cross braces.
