We bought a second stirplate on ebay. Our homemade one did not perform as well as we had hoped. A bit of tuning and adjustments would make it work but the effort was too great and the loss of yeast would be too much if it threw the bar in the middle of the night.
We sanded the pretty ragged body a bunch and then hit it with a good shot of Rustolium. The paint is the double coat version. This, allegedly, puts two coats on each time. It just sagged. While not super pretty, the new coat of paint will keep it from getting more corroded and keep the brewery clean. Plus it is orange. Orange rocks.
