Good morning, Members may be interested in the following classic books available as free downloads from Internet Archive (www.archive.org):

In the left-hand box where the different formats are shown, click on "All Files HTTP" and then chose the pdf. If you just click on the PDF (Google.com) it takes you to Google and this is a waste of time Holtzapffel, C. (1881) Turning and mechanical manipulation. Intended as a work of general reference and practical instruction on the lathe, and the various mechanical pursuits followed by amateurs. Volume IV: The principles and practice of hand or simple turning. Holtzapffel & Co., London. http://www.archive.org/details/turningmechanica04holtuoft (71MB) As far as I could find, Volume V is not available on Internet Archive. Pity. All volumes have been reprinted by The Early American Industries Association, but I don't know if they are still in print. I guess a check on Amazon would show that. Also available is: Holtzapffel, C. (1847) Turning and mechanical manipulation. Holtzapffel & Co., London. 2nd edition This seems to be an early version of Volume I above. http://ia331420.us.archive.org/1/items/turningandmecha01holtgoog/turningandmecha01holtgoog.pdf (17MB) See above re downloading Google scanned versions Ibbetson, J. H. (1833) A brief account of Ibbetson's geometric chuck, manufactured by Holtzapffel & Co. with a selection of specimens illustrative of some of its powers. John Holt Ibbetson, London. http://www.archive.org/details/briefaccountofib00ibbeiala Have fun! Now if I could finish looking at these things, and writing papers, I could actually get to my lathe and turn good metal into swarf. BTW: Googling "sundial" in domain "archive.org" gave 2970 hits with many titles of interest. Looking at just those on Internet Archive with "Sundials" as subject gave 29 hits (http://www.archive.org/search.php?query=subject%3A%22Sundials%22). I don't have time at the moment to go through these. Perhaps someone on the list could do so, and tell us all of the goodies that can be found here??? Familiar authors are Biot (multiple volumes), Henslow, Gatty, and even NASA. Searching Internet Archive for "Sundial" gave 115 hits, with a lot of extraneous titles. I don't have time at the moment to go through these. Perhaps someone on the list could do so, and tell us all of the goodies that can be found here??? Cheers, John John Pickard john.pick...@bigpond.com
