Wolfinger’s Regulator Savvy is still readily available; and I believe that @rsingler is using that text for his seminars.
From an earlier thread on the merits of each author's book:
"Wolfinger, while fabulously knowledgeable, is far more abstract in his approach and, unabashedly, plugs his company's service equipment, Peter Built Co (see "A Word About Bias" on page 105) to the open exclusion of most everyone else, with little to no discussion of particular name brand regulators, if I recall correctly; but his thorough coverage of applied physical theory and engineering is valuable -- and the illustrations on principles are quite clear."
Discussions of case geometry fault are all well and good; but I always favored Harlow’s far more grassroots approach, on cobbling together your own tools from dowels -- and even building you own IP gauge, from local hardware store stock, which far more closely mirrored my budget, at that time . . .
