      I am currently rebuilding a very old Stuart No1 engine. Among a host of other problems, the ports are badly cut, and there is a blowhole next to one edge of the exhaust port. I intend to insert a newt port face, made from cast iron, into a close fitting rectangle, milled into the existing portface of the cast iron cylinder. The new face will be slightly pround of the old face, and proportioned so that the slide valve over-runs it. I intend to seal/retain the new portface with “Araldite”. Will this be suitable, or would one of the “Loctite” preparations be better? If so, which grade please?

          I’ve seen it done on a 4″ traction engine with Araldite, go for a slower setting one not the 5min rapid.

            I can thoroughly recommend ‘JB Weld’ for applications such as this.
            It is a two part epoxy based product with good heat resistance compared with araldite.
            There are two versions – the longer curing time has better heat resistance.
             
            I used it to repair similar faults on a Stuart Twin Victoria cylinder to great success. It ran for many years albeit on saturated steam without failure or degrading but possibly more substantiating was on home produced glow engine  silencers where it withstood the heat from the exhaust gases.
             
            Heres a couple of pics of it being used to bond the steam chest to a 1/3 larger Waller Table Engine cylinder currently resurected!
             
            Hope this of help

              This will take you to an album with pictures of a CI face being made and then glued in, give me a while and I’ll find the builders description of the process.

                Thanks for the feedback. I can now proceed with confidence. I knew someone would know.
