The cardboard option got me thinking, as it'll take me a while to make anything worthwhile as a cold smoker I'd look at the low cost options.
Like the idea of macs "disposable" double skin (thus weightbearing) cardboard unit.
Anyone comment / tried getting hold of the thick walled cardboard veg boxes to jerry-rig & play with before moving onward & upward?
The card veg boxes are typically pretty durable & hard to crush, making them potentially very stable when combined with a few racks clamped between them, whether upright or stacked, having cut our some of the base to allow smoke movement, or to accomodate a rack per box if stacked normally.
Just thinking this might be an option for a stack, possibly using some commonly thrown away material (& some gaffer tape) & fashion an outer wall & smoke barrier out of other waste material.
thinking cubs / scouts etc to demonstrate simplicity / a project, use a series of kitchen roll tubes or similar to create angled air intakes & the smoke out chimney?
Any downsides I've missed prior to suggesting this for my local pack to try some cheese & other stuff? ..was thinking a pack night to assemble, a pack night of light & smoke with them all trying their piece on the 3rd week, or at a weekend camp as a build, smoke & eat project.
camp seems a good idea as they are usually hungry enough to devour each other regardless!
