Hi Airmodel,
Yep it is, K1 currently undergoing a boiler rebuild, I think it's still happening as it started to have the tubes removed over a year ago, the info coming out of Wales is a little slow. I posted up some pictures of the castings some time back. They were cast by a guy in Queensland, & have been aging under my bench for far too many years!
So no I don't do my own castings would love to though, or at least live close enuff to somebody who I could help, read hinder, who has the knowledge & was willing to pass on the skills! 2500 Kms isn't quite close enuff!
What plates did you cast for your brother?
Cheers Kerrin
