Model Engineers Workshop magazine issue 234 (about three months ago) ran an article on making a fixed steady for a Warco 220. As luck has it the 220 has the same/very similar type of dovetail bed ways as the ML10 so should be easily adapted. I think you can buy back issues/articles from the Model Engineer website, or maybe at Newsstand.co.uk
Yes, waste of time looking for Myford stuff on Fleabay Oz. Very rarely much comes up except the occasional complete lathe. And when they do, prices are so high that you might as well buy from eBay UK and pay the postage costs. And ML10 stuff is even rarer in Oz than ML7 etc
