Will I need to buy textbooks?

In a word, "No".  We provide each student with a shop copy of Barnett's Manual, 5th Edition, Volumes 1 - 4, and a shop copy of Dr. Arnie Baker's "Bit Fit", both for use during the course.  We also have a full reference library including Sutherland's Handbook, manufacturer technical documentation, and distributor catalogues available for students' use during the course.
