Well guys a company has been throwing these shakers away every couple of months. Usually I see anywhere from 2 to a dozen sent to the scrap yard. So I get to thinking they are motor driven, speed controlled and include a timer so lets take one apart and see if we can make a stirrer. Wala bingo within a few minutes I find that it's going to be easy to strip the shaker down just leaving the spinning motor head to glue a magnet onto. I have 2 so far so I plan on donating a couple to my local brew place since they taught me how to brew. Check these baby's out!
Here's a link to the pics and video!
Now don't go PMing me yet. When I get the others that were going to be thrown out home I will spread them out in my area first for those that can pick them up. There are plenty of these shakers from different manufacturers on Ebay but you would have to jump on the low priced ones. The reason these are thrown out is because the rubber gasket fails and the shaker gets a little erratic. Since we only want to spin a magnet oh baby we will now have one smooth machine. My bet is they could also be used in wine making to mix in the sulfates or whatever. I see no reason why you couldn't set a 5 gallon carboy on there and mix away.
