Dear Skapegoat, You're probably going to have difficulty scaling up to 5 gallons using magnetic stir bars. The largest bars I have used are only 6.3 cm(2.5 inches). They can stir a liter or 2 reasonable well but 10 times that volume I have my doubts if it will mix well enough. You would have

I have been working along the same exact line of thinking. Tom is probably right about stiring 5 gal of oil with a bar magnet. However where a magnetic stirrer really shines is in mixing methoxide. Stirring bars work great so long as they are confined to the area of the rotating magnetic

Thanks. I was going to attempt to make my own. Regular stir plates cost more than I am willing to spend. I'm thinking now it will just be easier to make a stirrer from a drill and perhaps if I scale up later I'll try to make a stir plate for mixing up methoxide.Juan Boveda [EMAIL PROTECTED]

I was thinking of attaching a permanent magnet to an the rotating part of an old juicer. I still want to try it just to see if I can make it work, but I think I will try something a bit more straightforward first...Joe Street [EMAIL PROTECTED] wrote: I have been working along the same exact line
