G'day All,
I come across yesterday "The Artificial Clock-Maker" by W.D.M.A. from 1696, as a free PDF. You've got to get used to the 'f' style symbol being used for the 's' in the middle of a word, but should be an interesting read.

The artificial clock-maker : a treatise of watch and clock-work, wherein the art of calculating numbers for most sorts of movements is explained to the capacity of the unlearned : also the history of clock-work, both ancient and modern, with other useful matters never before published : Derham, W. (William), 1657-1735 : Free Download, Borrow, and Streaming : Internet Archive
One thing I've already come across is the author's choice, when calculating fusee (spelt 'Fufy') turns etc, of a watch beating 20,196bph! I wasn't aware of watches beating this fast in the 1600's (heard comments of 14,000bph being considered ok).
Been having a bit of fun with the GIMP graphics program, cleaning up a few pages. I'm getting faster as I get the hang of what has the best effect on the image. See below, especially the bottom of the first page (and it's cleaned up partner) for the above reference of BPH.
Oh, and one curious thing; they print the first word of the next page under the text of the previous, thereby, I suppose, to enable you to read more smoothly, especially out loud.
Hope you all are keeping well and safe.
All the best.
Cheers
Duncan
