I had built a stir plate many moons ago, design based of internet searches and HBT.
This little diddy worked wonders and never had to worry.
However this past weekend i made my starter and fired the old girl up, it spun, but kept throwing my stir bar off the magnet, hours i tried to get it to work but alas, no go.
Any thoughts on what could have happened?
Computer Fan; 110 volts with speed controller
Rare earth magnet
2L earlymyer flask
1 inch stir bar. I also tried with different sized bars. 1/4 inch to 2 inch with every size in between.
Nothing has changed in the set up.
Thanks
Dan
