Ok, so i have this idea but im REALLY high and dont have the mechanical aptitude to pull this off, lifted or not. If somebody can put this together and get it up here, it might be cool. On the other hand, if this already exists, i sure didnt know about it.

So I was on ebay looking at different tumblers, and im under the assumption that they are expensive to make and I was right, but i personally think you're paying for a name. They dont look all that intracate!

Im guessing that this thing is auto cranked so it just swings around and around and allows air to travel thru? i dont really understand the mechanics. somebody with a tumbler plz explain what they do and HOW!

Anyway, im thinking a poster tube, you know, the one with the white caps at either side with a few holes poked thru? the bones of the structre? im not trying this or anything, hell im not even finished bloom cycle im in like week 2! anyway, i just thought this might be an easy and inexpensive way to create something for the good of all humarijuananity! lol
