What an idea! In my travels I worked for a failed dot.com and when we closed we raffled off the kitchen supplies and I won the Starbucks french press. I might have a starter vessel and didn't know it!!

Do you think you stir bar issues are due the french press vessel or fan speed

I'm thinking the stir bar is my problem but I'm not sure. I tried different fans, many power supplies and many magnets. It works most of the time with deep vortex but I have to play with it a bit. It's not consistent.

I bit the bullet and ordered a 1" stir bar from midwest to test. The french press vessel seems to work fine. Bottom is nice and flat. It might even be pyrex so I can boil and chill without transfer but I don't want to risk it if I'm wrong.

I'm wondering if the flasks have slightly concave bottoms so the stir bar auto-balances and spins better due to less friction ....

Hopefully not a stupid question but do you really need to glue the hard drive magnet to the steel washer? My magnet feels firmly attached to the steel washer on it's own. Will influence from the stir bar be strong enough to move the magnet from it's location on the fan?

Thanks so much to Tony for posting this. With parts and instructions even an all thumbs guy like me can build this (and I did Wooo Hooo!!)

My solution to all the different problems I have encountered, flasks shapes, sizes, etc.

The four magnets have a pull force of 5 lb each.


2" stirbar in action.




Cheers,

Claudius, what are the +/- orientation of the magnets?

++--?

Claudius's is similar to mine. I use 4 magnets across in a line, --++. I have had the most success with this orientation. It greatly reduces the tenancy of the plate to throw the stir bar at high speeds.

Very nice!! I'm going to start going through this thread to post different magnet setups people have used that have been successful in my original post.

I actually turned my fan all the way up and managed to throw the magnet right off the washer before I had glued it...

NN SS pole

Info:
My fan is a 120mm, 24 VDC.
The 24 V fan I picked has more torque than the 12 V version.
Magnetic shielding (washer) is a good idea for most fans.
My selected fan has metal plates below the plastic covers, no washer required.
