Thread: Question on welding cast iron.

You must do it!

Your vitals have already been removed and kept in a safe place so there can't be too much more pain.

All I can offer is moral support

My question is, how successful would welding cast iron for this application be ?, bearing in mind that helical gear end thrust will try to separate the welded joint.

If I read this correctly you want to weld a nissan t-case housing to the nose of a sals?

No way you can sort out a bolted joint between the two instead?

Bush65 (John) would be the best person to answer this stuff. However he is currently incommunicado (like you, now living on a remote bush block - only without internet).

I believe dullbird has his mobile number, so if you ask her nicely, I am sure John would be happy to advise.

Not quite Ben. I already machined, welded a bolt flange to, and refaced a Salisbury pinion nose about 20 years ago. I also fabricated a bolt on drop box casing to use Ford Bronco t/case sprockets and chains, but some tea leaf knocked that bit off along with several tons of vehicles and good bits a couple of years back. I still have the modified Salisbury diff though and want to bolt a sectioned,narrowed Nissan t/case to it. My old rearmost drop box, made from series t/case gears to bolt to the Rover diff, which was also knocked off is too short between shaft centres to clear the hypoid offset of the Sals, hence the thought of using the Nissan case which has larger gears.
One Iota. My vitals wouldn't be safe at all if my wife finds out what I have in mind.

We'll take it for granted that she can read your mind.

However if they are kept in her handbag it will take her a while to find them so you have a bit of time.

You've seen inside my wifes handbag then? Or are all woman the same? I reckon I could survive for a month with the contents.

Sorry for the non technical hijack

All women can read their men's minds and their handbags are equally chaotic and full.

Just as well there's enough in them to survive for a month - 'cos if you fell in it would take that long to find your way out

No problems welding cast iron. Has to be clean though. As in not soaked in oil. Has to be warmed up before welding to avoid heat shock and cracking. Need to buy cast iron welding rods, not sure you can get them in small quantity`s though. I`m guessing you won`t be needing a lot. You can also braze cast iron with good results.
