I guess I could have (should have) expected comments such as those above. I just wish the tone of the dissent wouldnít exhibit so much vitriol. Been guilty of that myself and I think it just stifles debate.
IMHO we all filter knowledge to fit our understanding of things. Exposure to many ideas and even prejudicesí are the ingredients that form our own unique understanding of almost any subject. One of the things I came to understand after more years of college than I want to admit, is that even experts on almost any subject often have huge differences of opinion with their colleagues. The subject matter progresses anyway.
To dismiss the rest of this book because of differences about terminology I think is shortsighted. Having not yet seen Tim Bartonís collection of books, I would never have been exposed to the Magee wire edging machine. Cool looking device. Also a quite large die created for a Pullmax to shape a fender. Interesting.
Best view of Elkold shrinking heads I have seen. Makes more sense now. Body hammers with one head removed for close quarters should be pretty obvious , but it never occurred to me until seen.
Anyway, this book may not be particularly informative to many of you highly accomplished folks, but it canít hurt to keep an open mind, and take a look.

Ain't a big deal ByronR. Over the years Kerry and I have pushed each others buttons. It causes us to think, other than that it's harmless. I'll have grape. Cheers.

Vitriol? What vitriol?

You wanna see vitriol, go to one of the hot rod forums.

Since we're a sheet metal shaping environment, and this book is about sheet metal, I think you're drawing too fine a line.

Do you agree there is a significant difference between a Yoder, Pettengil, etc, and a Pullmax, Anoka, Trumph, etc? My only point is that their IS a significant difference and lumping them all together and calling them power hammers is misstatement and a disservice to his readers.

Reciprocating Machine ; making a dish, the machine is press stretching
no way to overstretch you can
hit some places more then other
if the shape is there it wont do
harn to hit again

power hammers ; making a dish , you can do press stretching with same
shape tools as the other but it will
always have the stretching you get
with hitting hammer and dolly

if you setup a pullmax for making a dish you can do so that a feeler gauge of your choosen sheet thickness would fit between the dies
eliminating stretch from hitting and only stretch by pressing

this is same reason Reciprocating Machine is more quiet
