I've been racking my brain and trying everything I can possibly think of but my homemade stir plate won't work with my $7 2-inch stir bar. I took a nail and a coffee stirrer and made a home-made stir bar and it works (not perfectly but it will get the job done).
I did it the same way everyone else does - pc power supply, fan, rheostat and a hard drive magnet, all in a cigar box.
I'm thinking if I buy a 1 inch stir bar it will work because the homemade stir bar is 1 inch but anything longer than the magnet itself doesn't seem to work
Anyone else had this same problem? Any suggestions? I've tried ceramic magnets but they didn't work, I've tried a variety of home made stir bars and some work, some don't. I want this thing to work with my store-bought stir bar although I think the coffee stirrer stir bar will be okay because it's completely sealed and the coffee stirrer is made to go in a hot beverage so I don't see how a little bit of star san or starter wort is going to hurt it.
I'm at a loss, any suggestions would be greatly appreciated.
