Oh my goodness, I just realized that there is a bigger, better version of Tim Mcreight's book, "The Complete Metalsmith"...
my paper back spiral version only has 192 pages...and Alec refers to and earring findings section on page 251!
I must procure this professional edition which has 312 pages!
Complete Metalsmith: Professional Edition Spiral-bound – February 1, 2005
by Tim McCreight (Author)
Spiral-bound: 312 pages
The Complete Metalsmith became a classic soon after it was first published in 1982. A second edition (blue cover) raised the bar by adding 50 more pages and using a larger format. To mark the millenium, McCreight revised it again, this time doubling the number of pages, adding color and using an innovative concealed spiral binding. This information-packed technique source book is on every professional metalworker's must-have list. With over 2500 drawings, the Complete Metalsmith provide a wealth of information on materials, tools, shaping, surfaces, joining, color, finishing, casting, stonesetting, chains, findings and mechanisms. Also included is one of the largest collections of charts and tables for metalsmiths. You’ll wonder how you got along without it!
