06/03/2026 Hand or Simple Turning by John Jacob Holtzapffel - Chapter 7 |
The five volume compendium "Turning and Mechanical Manipulation" by Charles and John Holzapffel started with Volume 1 in 1846 and ended with Volume Five in 1884. A planned sixth volume was never completed. The series is a treasure trove of hand tool technology. Volume Four, on Plain Turning, and Volume Five on Ornamental turning are the bibles of their field.
Unfortunately the Holtzapffels, both father and son, may have been great tool makers but they were crappy writers of how-to books. In the time between their era and ours, "how to" instructional books have become more engaging and and much more than just a recital of facts. And of course, the act of writing a book - whether in the 19th century or today - doesn't of itself confer an engaging writing style. As a matter of fact, most Victorian books I have plowed through are pretty turgid. I can claim the honor of having read all six volumes of "The Morning Chronicle Survey of Labour and the Poor" a a groundbreaking 1849–1850 newspaper investigation into the living and working conditions of the British working class mostly written by the crusading Morning Chronicle journalist Henry Mayhew. I found the section on Billingsgate Fish Market to be particularly evocative and engaging - nearly two hundred years later, you can still smell the fish. Later in that section Mayhew notes that the description of the fish market section was contributed by his colleague at the Morning Chronicle: Charles Dickens.
But back to Holzapffel. I realized that in order for me to understand treadle lathes, I would need to plow though Holzapffel's description of using a treadle lathe - possibly the only instruction on using a treadle lathe specifically with hints on treadle speed, how to stand, and other treadle specific info - however turgid I found his prose.
I found it tough going. Too much of my time was spent getting lost in the text (in a bad way). And then I had a brainwave: what would happen if I took the important bits of the text and fed it into the AI chatbot Claude? I asked Claude to take the text and turn it into modern English. And it did - and wow, what a massive improvement. So here ya go. I don't have the time to do the entire book - you can if you want to; it's pretty easy - but here is what I hope is the first section of something useful. The PDF is also posted on the Gramercy Tools Treadle Lathe product page.
One important point. I look at this modernized version as a inexpensive translation. One wonderful feature of the modern internet is that Google and many services will do an instant language translation for you. The translations are rarely perfect and may miss the nuance and discernment that a real translator can provide. However, it's hard to imagine how a niche project like modernizing inaccessible language in a classic woodturning text could ever be economically viable, so having a starting point is great.
A note on the text: As I wrote in a previous blog, "softwood" in this time period included all the furniture woods, including oak. "Hardwood" referred to like Ivory, Rosewood, Ebony, and Boxwood. Meanwhile, a lot of modern forms such as roughing gouges hadn't been invented or named yet and so are not mentioned in the tools section.
Here is the link to the modern version of chapter seven.
and here is a link to the entire volume four in all its glory.
PS We used to stock reprints of all five volumes of Holzapffel but slowly they have gone out of print. We do have a single copy available of Volume Two which covers construction, action, and application of cutting tools and the machines derived from hand tools.
