Gingery Lathe In the spring of I ordered the Gingery series of books on how to build a metalworking shop from scratch. I started with a 5 gallon steel bucket lined with firebrick mortar for a foundry. Fine sand from the bottom of a Virginia trout stream mixed with bentonite clay for a binder was my molding sand. Scrap aluminum was used for melting stock. My woodshop was already fairly well equipped and I had the experience of building a wood lathe behind me, so I felt that I was up for the challenge of building some metalworking equipment.
To me, this was one of the great learning experiences of a lifetime. It is a fascinating experience to build a precision machine tool from scratch. It is also quite laborious. In addition to lifting, flipping and ramming up sand molds, tending the charcoal foundry, pouring deg aluminum and hacksawing, you have many hours of filing and scraping to look forward to.
I spent about 24 hours just scraping the bed flat. You will very quickly understand and appreciate why precision machinery costs what it does, and you may wonder why it does not cost more.
In my opinion, the real incentive for starting down the Gingery road, should be for the education and experience. When you have a machine or two under your belt, you should be able to design and build nearly any machine or mechanism that does not require more than a quart of metal in a single part See the IsoBevel Grinder.
You will also understand how to design patterns and have some ability to predict where you will need risers when making a new part.
In any case, I finished my Gingery lathe, about 9 months after I started working on it in the evenings and weekends. It works as advertised and turns on the faceplate and centers quite nicely. It would be nice to have an array of chucks to reduce set-up time. I have turned many steel and aluminum parts on the lathe; however, I have not successfully turned brass. Brass usually sets the machine to chattering.
The aluminum lathe components do not have the mass or rigidity of a commercially made lathe. If you are interested expanding your horizons and in the education and experience, build it.
