I came across this web site just playing around. Looks like a Polish web site, so there's some serious sausage making on these pages. Find your way to the photos of permanent type smokers in there. You'll find some pretty good ideas for building your own if your so inclined. Heck it's worth taking a look just for the pics of some of the smoked products they're cranking out! Enjoy, JB
