Hay there,
I am building s stir plate using the onebeer web sight for gidance. I have it all wired and changed the power source from 5.6v to 12v. Now I can get it to stir but the magnet keeps spinning off when I turn up the speed slowly. Any ideas on how to fix this? The stir bar is 1” from B3 and the magnet is like the one at “onebeer.com” but with the base plate still attached. It tried to separate the magnet from the plate but it started to chip. So I just attached the entire thing. I do get a vortex but in my 2000 ml flask it is about a 1” depression.

HELP…..

Thanks
Tim

Now loking at the sight my vortex is like his in the far left pic, http://onebeer.net/homebrew/images/stirplate1.jpg
is this good? I see some stir plates that look more like a tornato!!!

Thanks
Tim

That's all the vortex you really need. I would suggest you go with a larger stir bar, either 1.5" or 2.0". I think you will have less problems with throwing the stir bar and will probably get a better vortex. This larger size will also help when you are trying to mix yeast sediment back into solution.

Bug's absolutely right...I asked Jamil the same question and he said that all you need is the beginings of a vortex to obtain all the benefits of a stirplate. Check out the newsletter, the question is featured in Jamil's ask Jamil section.

Are there any negative affects of having too great a vortex?

As I understand you move to Sedona, open a New Age store, go broke, come up with weird theories about UFOs, and spend alot of time hanging out at the Oak Creek Brewery bar.

Of course that last part ain't so bad. Trust me.

As a matter of fact, there are. At too high of speed, there is a shearing action that takes place, tearing apart the yeast cells. A nice breeze feels good. A 200 mile an hour wind will rip your face off. Yeasties like gentle breezes too.
