Best way to "glue" cast iron

[meoldbangar]

I have a thin bracket 3/16in thick made of cast iron of an engraving machine
(Taylor Hobson CB ) that I accidently broke. Tried a few epoxy's without success
Any member heard of JB Weld (used to epoxy weld exhausts) or similar
Help most appreciated

I use JB Weld in many of my modelling endeavours (model aircraft before any of you get any 'funny' ideas!) - while strong, it's still a metal-loaded epoxy resin and will soften with any substantial heat. If the broken bit hasn't got to take much load or heat, then it's certainly worth a try.

 

[meoldbangar]

There is no heat and its just to tension a belt
I actually drilled and fitted a pin in the joint to take out any stress

Thanks again GordonTarling

I used it to mend a broken mounting lug on my son's windscreen wiper linkage. It's still holding nearly two years later.

Brazing is an option....

Cast welding is another.

Why not ask Taylor Hobson if they can supply a new part?

I have a set at work where are you situated if not to far i can drop it off.

Oh, no they didn't.

They still make metrology testing devices now.

Belzona make ******* hard glue - but its still basically an epoxy. It aint cheap though!

Its an engraver
See my first post

Taylor Hobson (Optics) are still in Business
Their engraver was developed to manufacture their optical moulds I believe

Taylor Hobson (Engravers) were bought out by Pantograph Services in Leeds
But they don't manufacture any more
They will refurbish my CB for a lot of money :0)

I am in south Manchester, a bit far, thanks for the offer

I agree the fuel cost would be a bit hard to justify!

I've used JB for years including sealing a spark plug where the thread had virtually stripped - very impressive stuff
