woodworking, Making a cheap cold smoker Part 1

My old cold smoker finally gave up the ghost so I'm building a new one out of some old stuff that I gathered up in different places for that purpose. Have a hot smoker but not fussy about the way that it stores or tastes after frozen in freezer a little while. Part 2 will be delayed as I had a bit of an accident which put me out of commission for a while.
