In the complicated world of Job Training it is quite refreshing to see that "New and Improved" is not always Best. I was first introduced to the Jack Benfield EMT bender and his Benfield Conduit Bending Manual in 1979 when I first joined the IBEW, and I found the tool and the Manual to both be Superior.
Why? Because they are simple to use!!
Presently, I train Electrician Apprentices on a daily basis,
and I find so many of the other manuals unreasonably complicated in their approach to EMT bending methods, especially for Apprentices who have been in the Trade a short time. When I see
an Apprentice failing to grasp the modern (and complicated) approach, I rely on the Benfield Manual and Jack's easy and amusing approach to developing skill in the Electricians Trade.
Todays Journeyman Level Electrician can also benefit from having a copy of this book. Highly Recomended!
