For those that "haunt" the flea markets and auctions, Jim Moffit's corn shelter book is a worthwhile investment. When I looked thru it I was amazed at the variety of shellers that were made. Without the book I would never have known what some of them were.
I would hate to think that I could be reaching over a $500 corn sheller to get at a $5 wrench, thus the rational behind buying the book.
And for what it's worth, I think it is very well done. Lot's of good photographs.
