Been working on my stir plate for a while and it is now completed. I do have to do some tweeking with fan heights and need some silicon orings for the ends of my stir bars. Picture on ebay showed smooth stir bars and the ones I got are hexagonal or octagonal and there is a ring in the center. The wobble is irritating but I do get a small dimple in my 4000ml flask and a bit bigger dimple in my 2000ml's. I would like a longer vortex but I get as long as things are moving it should work out just fine. Hope you all like it. I looks really cool with all the lights off and all of them on in the stir plate.
