Default 5000ML (5L) stir plate build

Finally got around to making a proper stir plate for my 5000ML flask. I could not find any cheap versions for a large flask.I had some issues with using a 2 inch stir bar so I went down to 1 inch and it works fine. The wood is a soft wood that I had hanging around the shop. I hollowed out the back for the computer fan. The wood is 1/4 thick over the magnet. The fan is held off the wood by 1/4 spacers. Rubber feet allow for air circulation. Standard rocker swithc for on and off and a rheostat for speed control.

testing to make sure it works before solder.


final product.
If I had to do it over I would make a removable power cord.

looks great! I love the idea of carving out spaces in the wood...mine's just in a little plastic radioshack project box

Thanks, that's the benefit of having a CNC router.

I have a question, I guess it may be more general than this specific build, but I think this is a valid place to ask it.

How does the fan cause the stir bar to move? Are there magnets on the fan blades? Or does the stir bar rotate based on the magnetic field created by the rotating motor?

Also, what issues did you have with a 2'' bar?

Magnets are generally mounted to the hub of the fan. There's a pretty great guide located here

As for the 2" stirbar issues...my only guess is that the magnets weren't perfectly mounted and caused too much vibration and continually threw the bar away. I've only ever used a 1" bar on mine so this is definitely pure speculation....

I superglued a metal washer to the fan. Then I put an old hard drive magnet on the washer ( it sticks by magnetism or you can superglue that as well). The stirbar is a teflon coated magnet. When the fan is turned on the stir bar turns. I can control the spped with the rheostat. The two inch bar kept getting spun off the magnet. I guess the magnet was not strong enough to hold the 2 inch one.
