Hi Andy, sorry for the belated reply. It was my understanding that the article on casting methoding would not be published. It was submitted 5 years ago and was part of a series that included pattern design (these were published). From a technical point of view, as a stand-alone article, I’m not sure it reads very well, and you may run into trouble following it out of context. For example designing the moulds for copper parts require additional steps and my home made inoculant to prevent inclusions.
I have subsequently written a complete book on casting for the home enthusiast, everything from 3D printed patterns (and how to design these patterns for negative draft extraction), to building a furnace and explaining the different refractories (and the most suitable for backyard use), shifting metal chemistry and even a new alloy for cylinders etc. The calculators are part of that package, are novel, the maths is ridiculous, took many years to develop and test and to be fair should not have been placed on a public platform.
For reasons I would not like to discuss on a public forum, I no longer contribute to ME and am no longer a subscriber, so unfortunately I have not seen the printed article. I make it a point to help anyone that takes the time to read my articles and give my ideas a bash; I also have endless fun sparring with the armchair engineers (always done in good humour and never hurtful!), but this time I’m tapping out…
