Thanks chaps, yes, a beadblaster would have been wonderful, as the rust was 100% cover over the steel, but underneath it was surprisingly not really pitted at all. The brown paint is an antirust coating. I don't really expect all the paint to stay on, but most of the forge does not get that hot!. The little torch set up is also an Alcosa product, bought at the same auction all those years ago. It is an alcosa brazing hearth which I also rebuilt. It runs on propane or butane, and compressed air from the green pump underneath. The circular top tray is firebrick lined, and rotates like a turntable. I will probably use it most for heat treat and preheating. I built the canopy so that I could connect it to my fume flue. I could do another slideshow on this if anyone is interested. I have thousands of stills, but did all this work before I had a GoPro, so no video, apart from a very grainy demo of a hot wire cutter I made., shot on the stills camera!
