I read a thread on here ages ago about using a SS mesh strainer with the middle pushed up as a cold smoking device.
Yesterday, I finally picked one up from the supermarket (for the heady price of £2.75!), pushed the middle up, loaded it with some pretty coarse hickory shards / dust and lit it using a tealight.
It worked fantastically! The Mrs. said that the cheddar I smoked was some of the best she had ever had :)
So, to the original poster; Thank You!
