Hi Mark A ??? - what was wrong with "Girl Mark"? :-)

I've become sceptical (okay - even more sceptical) about shaking stuff up in bottles. I posted this recently about it, and also about test batches for acid-base - guess you missed it because you were in Iowa: http://archive.nnytech.net/index.php?view=24875&list=BIOFUEL This is the acid-base bit: >For acid-base two-stage mini-batch tests, by the way, we stand a >small stainless steel pot in a double-boiler on a hot plate and >agitate with a drill and paint-stirrer. No problem. It's not actually a double-boiler, it's for making spaghetti - the inner "pot" is full of holes like a collander. Pre-heat the oil in the "reactor" pot. Pre-heat water in the double boiler. Figure out the water level first - as much as possible but not enough for the reactor pot (plus oil etc) to float. The reactor pot has a quite tight-fitting lid with a hole for the stirrer. The reactor pot is kept in position with four small PET bottles filled with water wedged between it and the collander. Drill mounted on a stand. Easy to maintain the temp. Then just follow the directions: http://journeytoforever.org/biodiesel_aleksnew.html Best Keith >mark ------------------------ Yahoo!
