I had been thinking about Jamil's wort cooling technique and about surface area for the last week. I love the temps he gets and the time he's getting them, but I don't want to buy a pump (even though I really really want one) and I don't want to clean the pump. So I've been thinking about other ways to increase the entire worts contact with the cold coils with out me leaning over the pot for 30 minutes stirring.

How about an electric motor sitting on top of a lid, with a hole drilled through? Under the lid, a pair of stirrers (a pair of spatulas or something of the sort) could have the wort in a constant whirl around and against the coils. I don't have much experience with small motors, but I'd think that a small fan would do the job.

Does anyone have any suggestions for where I could find a small motor? and the type that would be right for this job? I've looked at some from companies like emerson, but I really don't know much about them.

Wort-O-Matic: Carl's Electric HLT

Says he used a "Molon motor from Herbach."

Chuck up a paint stirrer in an electric drill. Mount the drill above your kettle with the stirrer hanging down into the wort. Rig the switch to "stir" at slow to medium speed.

In response to carl's wort o matic, 500 bux?!?! Yikes. I'm thinking a 30 dollar fan hooked up to a... paint stirrer, not a bad idea. I wonder if I can find one in stainless steel.

side note, if the search function on this site had the same capabilities of the "similar threads" box here at the bottom of the page, it'd probably be easier to find what your looking for. I feel like I find 3 threads with information I'm looking for, AFTER I post, every time.

Find an old electric ice cream machine.

I made my HLT stirrer out of a 150rpm AC continuous duty gear motor from McMaster Carr. It was $50. The price of my stainless prop,... no comment.

I got one at the thrift store for $2.50 I think. My first plans were for a mash stirrer, may be use on the HLT though to get consistent temps without recirculation. You may want a larger paddle with the ice cream motor than you would with a drill due to speed.

The price is (supposed to be) for the entire HLT and includes everything from a PID controller to an extension cord, but oddly enough doesn't include the price of the motor or prop.

Here is my ultra-cheap solution to more effective stirring. It isn't continuous, but it evens out my temps VERY quickly. This will become a manually operated steam wand along with my 16 qt. pressure canner. Working on some fittings and high-temp hose. May not be helpful, but it was incredibly cheap, just dow rods inside a pvc pipe, and copper plates shaped on a belt sander.

Cheers! Hope I didn't ghetto up this thread too much

By the time you get this made I would bet you will be right in the same price range as a march pump. The march can be used for a bunch of things during brewday and will make your life much easier. Cleaning is as easy as running your cleaning water with PBW or Oxy through it for a couple minutes. Easy as pie.
