Mending cast iron?

I'm in the doghouse. Like a clumsy twat, I knocked over a cast iron leg (from a victorian cinema seat) that broke off the top part.

I've googled and there don't seem to be any non-industrial ways to mend it. Anyone know of any super-uber-glue type stuff that might work.

It's not weight-bearing so I doubt it needs to be perfect, but I don't think normal glue is going to do the trick.

Thanks

ask Brucy to do it for you.

try that 'chemical metal' stuff you can get in B&Q etc...might hold it for a bit

Two part expoxy or JB weld should do it if it's not load bearing.

cant you just weld it?

To add some strength, hold in place and drill through at whatever angle goes through both parts.

Choose a drill size such that you can then lighty hammer a pin (spoke) through both items.

If possible place more than one pin, file off ends to finish

yes but it's a fine art.
my old man welded up some marine engine head and block castings that cracked. it involved some very expensive cast iron rods, a pair of bellows, a BBQ, 5 bags of charcoal, a fire blanket, 2 welding aprons, 2 pairs of gloves and a couple of buckets of water. basically he got the block hot as fuck in the big BBQ which was near red hot due to the bellows, gas welded the cracks whilst my mum kept him doused with water then threw the fire blanket over it and a bit more charcoal and left it to cool for a day.

a block for a 6cyl marine diesel is very expensive so it was worth doing. basically the problem is when the metal cools it will crack hence welding it with the whole block hot and letting it cool slowly. if you use the wrong rods and weld cold it will crack.

Ta - will try the chemical metal stuff with a strengthening pin, before breaking open the BBQ.

Fred Dibnah would know but sadly, he is dead.

fred dibnah whould make you a new one from a peice of old steam engine. after building a steam engine to drive the bellows and mining his own coal to heat it with.

And some 9 months later you were born.

Chemical metal = brittle (relatively) great for filling, less good for bonding duties.

I would go with a two part epoxy, Loctite is a good one (B2013 structural adhesive).

Cheers Tynan - will have a go & report back.

the chemical metal is 2 part epoxy based

Two other methods. Not as good as Mr Smiths Dad clearly but a lot easier to do.

crazy brazing, my fav.

I know a method, its the same method they use to join train tracks. Got an metalwork text book somewhere, details in the morning.

Thermite? there will be nothing left of the work piece:) aluminium oxide, iron filings and a strip o mags.

word, thermite fusion will leave you with nothing of the pot and most likely a fuck off hole in your floor

dibnah was the man. complete arsehole to his wife's and left nothing for his kids but ask him about one of his engines and he'd talk to you for hours. hell ask him about anything mechanical and he'd talk to you for hours.
to the outside world a real nice guy shame about his family life really.

he kept them in shoes and warm winter jackets what more could a wife and kids ask !
