I said check out his book, not follow his patterns. There are some great ideas in this build, but also some things Gingery did better - and since Gingery explained why he did a lot of things like he did you will likely in turn be able to adapt the good ideas to this build. The way Gingery does the head stock is much better than this cast in place option for example. Combine the two and you will get better results.
BTW, if you are serious about building a lathe I’d recommend epoxy-granite not concrete or castings. Something more to research before building (or maybe just stop someplace and build - your choice)
