Something similar with Chuck Ranum's setup - see how he mixes methoxide (about two-thirds down the page): http://journeytoforever.org/biodiesel_processor4.html Chuck Ranum's biodiesel processor Best Keith > Tom > > ----- Original Message ----- > >From: <mailto:[EMAIL PROTECTED]>Derick Giorchino >To: <mailto:Biofuel@sustainablelists.org>Biofuel@sustainablelists.org >Sent: Sunday, October 02, 2005 11:06 PM >Subject: Re: [Biofuel] disolving lye > >Hi there > > I have found a good way to mix the methoxide.
