My magnets are too weak and want to order some new/better ones -- any recommendations?
I have a homemade stirplate that I use a 1 inch bar on as well as a 3/4 inch bar.
My magnet came from a harddrive.
Also when getting your stir bars make sure they call have the band in the middle for rotation. Some do not.

It gives the bar something to rotate on reducing friction and allowing better vortexing. plus it makes less noise. Also helps if you have a weak magnet.
@MSUConrad, I was curious about that, I just finished my stir-plate build and after testing with water and some black pepper I almost dumped my stir bar down the drain and was curous what to do if it ends up in the fermenter... Thanks for the tip
It's a good idea to have an extra magnet around to attach to your flask and hold your stir bar when decanting and pouring your starter into your batch. Unfortunately, if you lose your stir bar in your fermentor, I would just suggest leaving it there until your transfer your beer. To me the risk of reaching in to get it isn't worth it, though I guess you could try to fish it out with a sanitized spoon. Since your stir bar should be sanitized, I wouldn't be worried about leaving it in the fermentor, just make sure you remember to get it out later so you don't dump it down the drain (made that mistake)...
LandoLincoln said:I bought some of those. The stir bar kept getting thrown. I took a razor blade and removed the band. No more thrown bars.
I just used the other magnet from the hard drive as a stir bar. Shoved it into a piece of vinyl tubing and then cut and sealed the ends of the tubing with pliers and a lighter. Works great.
No but I use this one:Has anyone ever used on of these cross shaped stirring bars? Seems like they would generate the most turbulence.

I tested my homemade "zero cost" stir plate with a hard drive magnet in a mason jar... awesome vortex. I think I'm going to try that since I haven't spent any additional funds on this.
Thank you, so o.k. to put it in Lehmans terms then just flip them till they are on the side that has a stronger "attraction" for lack of better words? Did you use just one of them??? Many thanks
