So I thought I'd take some of the floor up.
It seems the original floor had completely rotten away over the years and had been replaced (very poorly) in a very piecemeal fashion.
The upshot of this was that almost none of the floor was extending underneath the shell any more.
Therefore, major rear-end-separation.
I managed to get the old gray/black tank out, but I had to cut it out of the belly pan. All the bolts had rusted around the old sewage connection and there was no way to remove it nicely.
The sub-floor insulation was a total mess.
It looks like there was layers of it sandwiched in between the frame and the floor. This had gotten damp and caused the frame to rust.
Upon examination, sizeable slices of rusted steel have come off the frame. I would expect the members to be rusted inside as well as out. While I was hoping for a shell-on restoration, this is looking to be increasingly impossible.
I am even thinking that the frame may need to be completely scrapped and duplicated.
This is very daunting. I have no idea how much such a thing would be to fabricate in this country, but I'm imagining in the region of £5k.
So whether to get myself along to some welding and fabricating courses, teach myself enough to take a crack at it, with some assistance from a professional welder?
This guy makes it sound and look easy, but I know it's a major undertaking.
Regardless, I have another problem in my way:
Given what needs doing, the workshop space I have is no longer going to be big enough.
SO I need to look around for another space to put this in to work. And that's going to COST. Probably in the region of £6k-8k per annum.
If I get a big enough space I can do a full frame off resto.
What do people think about the likelihood of me being able to put together a new frame with no previous experience in metal work?
That's all for now.
I'll keep you posted about what happens next.
