it looks like 17 years of standing and a little too much elbow grease (and carelessness ) has resulted in this approx 1" hole in the rear plate
of my axle - any suggestions as to how to best fix it? the steel around the immediate area sounds very thin
cut it off completely and weld on a stainless steel dog bowl
well its probably a good thing that you foud it now and not when all the oil drained out.
I would keep going with the derusting and see whether you really do need a new pressed steel cover
is that a genuine recommendation? because it does almost sound plausible 
I've got an Atlas axle with a similar problem but the cover is bolt on. Ikea is a good source of stainless bowls in a variety of sizes 
Gas weld or Braze/Silver Solder a patch on
Welding mild steel to (most) stainless steels isn't an option.
What about a tupaware bowl if you cant weld stainless to it?
Im sure iv seen on here you can buy new back plates to weld on.
standard mig wire will weld stainless - the only problem is the weld isn't stainless therefore will rust. I've done it with argoshield (co2 / argon mix). No idea how strong it is yet, but the welds i've done aren't structural.

Does the main axle housing ever rot through on the English axles, or is it just the diff cover which is exceptionaly thin?

Syd is correct, the hub shaft spindle nut on Tutamkamun's ceremonial chariots were welded using these materials.

Pray tell, Just WHERE do you get your misinformation??
People have welded/brazed steel and stainless steel together for generations. Geez, I can even go down to my local welding supply shop and get special arc rods and tig rods for the very same purpose.
Cheers,
SYd.
Ahhh--Now I know. Even I can 'cut and paste' from an internet blurb.
It must all be true. After all, you read it on the internet! It's a shame you don't understand it.
You still don't say why 'stainless' and other steels cannot be welded to each other, as is common practice in many industries,
including shipping, as you should well know.
That's why the special rods are available for purchase at my local welding supply shop. Would you like me to send you some, just so you can
practice and learn something new and real life applicable?
Cheers,
Syd.

Well, your wording came direct from a book, as I suspected.
Your lack of a sensible, laymans explanation as to why two differing steels should not be welded, still shows a lack of understanding of what is
written in the book. Tell me why 'stainless steel' is called so, and the reasons for it, in terms not out of a book. If you can.
I'll say again, people weld 'stainless steel' and ordinary steel to each other every day, with welding filler rods made specifically
for the purpose.
Cheers,
Syd.
30 years ago I saw some materials welded by friction welding at the Welding Institute near Cambridge . Ferrous metals joined to non ferrous simply by applying speed and pressure. The point I'm trying to make is that although perhaps not ideal, dissimilar metals can be welded.
What is it about English axles and mettalurgy arguments Mr Trident?
As with our discussion a while back (regarding whether or not to tack weld bearing retaining collars on English halfshafts), I think again you're
failing to acknowledge the differences between lab theory best practice and real world proven application.
If it was a rollcage mount or suspension pickup being discussed here then maybe the solution wouldn't be suitable but in this case all the mod
needs to do is hold oil in the diff so its hardly likely to be unduly stressed or be catastrophic even if it does eventually crack!

Would it not be easier to get a new plate jobby or another axle tube?

could i a complete non expert (*) comment.
You can weld dis-similar metals together but the weld will have weaknesses in them. Only someone who knows what they are doing will understand the
weaknesses and the effects of the weaknesses.
Muppets like myself happily weld two bits together and hope the effect doesn't bite us! (in my case my exhaust mount break).
(*) ok, brag moment, i did once pass a welding city and guilds, but that taught me how to hold a welder and not a lot more!

He's my tuppence worth.....
I agree entirely with Britishtrident. What he's saying has dragged me back to my 'Materials' lectures and what he's saying is,
unsuprisingly, correct.
However, if we are still talking about welding a dog bowl to the axle, the chances are the dog bowl isn't, by definition, stainless. If it is,
it's probably of such poor quality, that finding a filler rod to match it would prove fruitless.
All these factors (and my professional training) wouldn't stop me from trying to weld a dog bowl to the axle. If the dog bowl would'nt weld
or get a good seal, then I'd try a small tea-tray. If that didn't work, I'd cut a circle of steel from the side of the fridge and weld
that it. If that didn't work............
The point I'm struggling to make is that, even if it's not 'good practise' to do something a certain way, it doesn't always
mean it's not possible!
And if welding fails, crack open the Araldite. Then the fibreglass..........

Well, Mr.Trident, I've never sent a u2u to you, as far as I recall. I have one forum persona, and I have the necessary intestinal fortitude to
stand by my statements.
From everything that you, and one or two others have said, cast iron cannot be welded either, nor joined to other metals.
As a last resort, there's not many metals that can't be joined by brazing. Which in some places is also called gas welding.
Alongside my car work, I also get involved in shipping and yachts. I see Ni-Cr steels being welded to mild steel far too often to question it, on
ships as well as yachts. Yesterday I was involved in brazing bronze and monel together. I suppose that can't be done either.
People are always trying to tell others what can't be done. Wake up, and start working out what can be done, and how to do it.
Where's Mr. Allanson when his welding experience and knowledge are needed?
Go into your local welding shop and learn something new.
Cheers,
Syd.
When you start calling people names, then the argument is lost, on your part anyway.

Syd,
It seems that for most of my early career I have been doing it wrong - the crucibles at Hincley Point must now be reinspected as they must be falling
apart, several ships in the merchant navy must have sunk by now, an oil rig in the same boat!
If a pressure vessel was made of stainless and mild, with an EN8 interlace and welded up with a hobby gasless MIG then I would agree iot would cause
problems.
What I suggested was a 6oz dog bowl being welded to a ms pressed axle case. The only stresses on this item would be its own weight and the lateral
weight of the pint of oil within - lets keep things in perspective!!
The whole thread has lapsed into a 'who knows most but has done least' competition, lets keep it practical, or rename the site
'Spaceshuttlebuilders.co.uk'
