Pete,
Something a lot of people don't know about Oregon (and I didn't know until I moved here 2 yrs ago) is that it is heavily populated with Scandinavians. That means sauerkraut and lots of it is made here. I've watched the demos three times now but haven't made it myself yet. Here are some links to information from Oregon State University Master Food Preservers.
