After removing valve and filling with water. I cut the top handle off it and cut out for the door.

I picked the door up last year, from a carboot paid a quid for it IIRC :)

How are you fixing the door Pikey, can you weld cast to the gas bottle:confused::confused::confused: (Serious question;)).

wasn't planning on welding. thou ya can weld cast if ya preheat it Apparently. gonna weld a "box" over the hole and either cold rivet or bolt the door surround into the box and seal with with fireseal.
 
Yeah 7018 rods, pre-heat the cast and cool down as slow as possible (in a sand box or something). I'm actually looking for old cast stuff like vices etc to practice my cast welding and it's fun to fix old stuff... oh yeah, this is a Land Rover forum!

Oh yeah it's advisable to peen it with a chipping hammer right after each weld to push the weld further in to the cast also.

Or weld a Mild steel frame round the hole in the gas bottle and drill and cold rivet the door surround into the new frame...

You should be able to with some 7018's from what I've read on welding site

Nickle rod is the way for steel to cast iron.

When do I use Lincoln Softweld® 99Ni, 55Ni and Ferroweld® electrodes?
Choosing electrodes for welding cast iron typically comes down to three things: cost, machine-ability, and whether the weld is single or multiple pass.

Softweld 99Ni (AWS class ENi-CI) is a nominally 99% Nickel electrode. Nickel is expensive, and so, therefore, is this premium electrode. The electrode will deposit welds that are machine-able, an important consideration when the casting is to be machined after welding. Repairs made with Softweld 99Ni are often single pass welds with high admixture. Even with high admixture, the weld deposit will remain machine-able. It works best on castings with low or medium phosphorous contents.

Softweld 55Ni (AWS class ENiFe-CI)is a nominally 55% Nickel electrode. The lower Nickel content makes this electrode more economical than Softweld 99Ni. Weld deposits are usually machine-able, but under conditions of high admixture, the welds can become hard and difficult to machine. It is often used for repairing castings with heavy or thick sections. As compared to Softweld 99Ni, welds made with 55 Ni are stronger and more ductile, and more tolerant of phosphorous in the casting. It also has a lower coefficient of expansion than 99Ni, resulting in fewer fusion line cracks.

Ferroweld (AWS class ESt) is a lower cost, steel electrode. The weld deposits are hard, and are not machine-able, but can be finished by grinding. This is the lowest cost electrode for welding cast iron, and the electrode has a very user-friendly arc. It can tolerate welding on castings that cannot be completely cleaned before welding. Ferroweld deposits will rust, just like cast iron. This may be important when repairing cast iron parts such as exhaust manifolds on antique cars.
 
This is a bit of a stupid question, how did you go about cutting the gas bottle and making sure it was fully discharged?


Edit: just re read your first post, ignore me

I haven't seen any wrong advice from anyone so far. Your good self included.

The fact is, cast iron, especially old cast iron is so unpredictable in its manufacture/structure, welding it can be a nightmare. Sometimes we follow all the proper procedures, use the "correct" rod etc etc and it still cracks.
