Hey,
Am currently wondering how Henry Maudsley made his first screw cutting lathe - ie how did people manage to start cutting accurate threads by hand so that Maudsley could use them to make his first screw cutting lathe. This would have been 1790's.
I get the impression from TMBR books (yes managed to buy them reasonable price at last - plough books ebay australia) that people chalked a spiral on a bar and then cut it manually.
Will continue to google.
Was wondering if anybody could recommend some other good books regarding how Maudsley did it with the resources available at the time and how we became progressively more accurate from hand cut threads to machine cut threads.
From what I've read so far we have Maudsleys screw cutting lathes started in late 1790s then we have Whitworth popping up in the mid 1800's with a device that measured lengths with an accuracy of plus/minus a few millionths of an inch - am interested in what happened in between.
So any good books to get me from just before Maudsley to just after Whitworth ?
Have tried Foundations of Mechanical Accuracy and although fascinating it doesnt quite cover what I was looking for.
I found this ............ "Henry Maudslay & the Pioneers of the Machine Age" and theres a copy in Victorian State library if anyone else is interested.
So ....... could anybody recommend any other books or web pages that would cover this period ?
