When I was renovating mine, that part of the chassis was full of water on both sides. LR don't put drain holes in that bit. So I drilled a 20mm hole on each side before painting it.
What's the deal with an aluminium body and steel chassis ? They need to be insulated, or specially welded ? Am, I asking you that, or informing you that ?
You get a phenomenon called galvanic corrosion. Whilst aluminium on its own is fine, when the two dissimilar metals of mild steel and aluminium are together, electrons flow between the two making the aluminium go powdery and grey. The solutions are: 1. Electrically insulate the body from the chassis but this is actually quite hard to do. 2. Just live with it 🙂. It's not a sudden think, it takes years to happen. And by the time it's noticeable you'll probably need a new chassis anyway!
@@BlakesDen Sure, I heard they use a special weld to keep the factory manufactured Land Rovers rust free. Yes, I heard about that phenomenon. I am a Bachelor of Science, with an honours degree. I thought that, one of the most interesting parts of the course was related to that concept. It was explained to us very well, by Dr Roy Lowry using the acronym. Oil Rig. And, that visual picture, of an oil rig. The good Dr. Explained the importance of using metals, of consistent consistency. But, my understanding was slightly different and, it was also related. Well. I don't want to give too much of my knowledge away for free. But, what I heard was they use a special weld, to attach the body to the chassis. What you, are talking about, seems to make more sense. Electrical insulation! Sure. I am a former Railroad worker, actually and, some of the Railway fixings are insulated. Probably, it's a popular misunderstanding, that the insulation. Was, to main. Well again. I am saying too much ! You did not hear, anything about a special weld then, some dad like figure chucked that one at me, in the style of a Daddy doing 80 mph on a motorway, answering questions from his kids !
@@BlakesDen Ah sure. That's interesting. Well, it's just something a colleague suggested to me. As, we learned about, the electrochemical series at University, perhaps, I puzzled over Land Rovers. On work experience, someone was giving me a lift to work experience in a Land Rover. I also, rode in one during an army adventure weekend away, with The Jobcentre. So, I wonder if you might satisfy my curiosity about, whether or not, a Land Rover body is insulated from the chassis, perhaps when they roll out of the factory? The bolts should really be insulated, I imagine. Actually, looking at many vehicles, it's a bit sad to see, how stupidly engineered they are. Yet, a full car build, of any quality is an impressive feat really. I remember hearing The British Army actually use old Land Rovers, bought 2nd hand from farms. I am interested in these engineering videos on TH-cam and my Uncle was a successful Mechanical Engineer at a West Midlands University in England.
Welding is coming along nicely!
Thanks! Its all down to the Rtech MIG rather than down to my skills
@@BlakesDen wouldn't say that mate, looked an awkward job!
I have the same welder, they are great bits of kit.
They sure are. My welding has definitely improved since I bought it.
@@BlakesDen mine too. It looks neat nowadays.

Not a bad idea. When I fit the near rear cross member I must remember to do something similar

I've never heard of a special weld. The body is bolted to the chassis not welded. You can't really weld dissimilar metals.

Thumbs up mate.
Thanks!
Love it!
Thanks, I love it too 😃
