I have 3rd edition. It is at chapter 3.8 Hi there, ASF, My copy (ISBN 085242 715 8) has 'Sections', not 'Chapters'. Section 3 runs from page 52 to page 56 and is entitled 'Standard Tapers and Collets'. It finishes with details of Clarkson end-mill screwed shanks (well, where else would you put that info?!). That Section does not have the Myford mandrel nose drawing we're discussing in this thread. I'm confused! Best regards, Swarf, Mostly! |
