The welded steel will warp over time without heat treatment, and the carriage does not fit very well on the bed, which you can see in the wear pattern on the bed guides near the end of the video. The cost to benefit ratio is a bit low on this project, and in the end itвЂ™s not a very good lathe. It would really be a good idea to build an insulated box, build a large fire under the lathe and anneal it before making the spindle and tailstock bores. David GingeryвЂ™s book for more details).ДЄ welded build like this is going to move around like mad as it ages. Then use the same setup to bore the tailstock bore. That guarantees they will be coaxial and parallel to the ways. Then feed the rotating boring bar into the work to bore the holes. ItвЂ™s just very slow and requires lots of measuring and adjusting to make precise parts.ДЄ much better way to bore the headstock for this design is to mount the front and rear bearing plates, mount a temporary boring bar on the cross slide and carefully align it parallel to the ways. That said, a good machinist can do quality work on a completely worn out lathe. With the workpiece rotating the drill *always* follows the axis of rotation. The wobble of the drill bit when drilling using the tailstock is indicative of considerable misalignment between the spindle and tailstock axes. I suspect that itвЂ™s not all that precise a machine. Nor was the alignment of the front and rear ways. However, I was disappointed that the alignment of the spindle and tailstock with the ways did not appear to have been done with any degree of precision. Clearly a lot of thought went into the design. This is the most impressive DIY lathe build IвЂ™ve seen. Prismatic ways wear straight down so the wear doesnвЂ™t affect the straightness. (I mean part of this is bias as my lathes are flat bed and itвЂ™s worked really well.)

Plus it has the huge advantage that regrinding the bed is trivial, with a single setup on a grinder that can handle top, front, and back way edges (where the gibs bear.) Also vastly easier to scrape true if youвЂ™re That Kind Of Person.

This vastly simplifies fabrication, especially if you decide to use a piece of precision ground flatstock as the bed ways on which the carriage runs.ДЄfter very significant use you can wear the front edge, which means you have to tighten the carriage gibs (and since itвЂ™ll be uneven wear itвЂ™ll mean youвЂ™d have to readjust the gibs for operation outside of the worn area.) But if you use a chunk of steel 20mm thick, thatвЂ™s more wear area than prismatic ways have, so it should outlast them. A lot of lathes were built with flat ways, using the front edge of the flat ways as the reference for the carriage. IвЂ™m curious about the recurring insistence on prismatic ways. Posted in Tool Hacks Tagged fabrication, lathe, Machine tool, machining, steel, welding Post navigation One thing weвЂ™d love to see on this lathe is the electronic lead screw that developed for his off-the-shelf lathe. It honestly looks like something you could buy from a catalog, and has most of the features of commercial machines. The completed lathe, powered by a treadmill motor in a way that would no doubt endorse, comes in at a beefy 450 kg. The angle grinder plays a prominent role in the build, as do simple tools like a hand drill, files, and a welder - and yes, the unfinished lathe itself, which was used to bore out the bearing blocks for the headstock. The base and bed of the machine are welded from scrap steel I-beams, and the ways are made from angle iron that has been ground flat with a clever jig to hold an angle grinder. Where most homebrew lathes tend to be the bench top variety and feature cast aluminum parts, went with steel for his build, and a lot of it. But two things make вЂ™s build stand out: how few specialized tools were needed to build it, and the sheer size and bulk of the finished product. WeвЂ™re used to seeing homebrew lathes, of course, and weвЂ™ve featured more than a few of them before. While we wonвЂ™t argue the primacy of the lathe in the machine shop, this scratch-built, heavy-duty lathe gives the lie to the latter argument - almost. ItвЂ™s common wisdom that the lathe is the essential machine tool, and the only one that can make copies of itself.
