Dear Paul and Gasification Colleagues, Normally I would not suggest something if it couldn't be made to work, and a double levered guillotine is widely used in steel working workshops for cutting heavy angles and flats. The only problem with these straight type cutting blades is that they don't open up enough to cut wood. Having been asked for a plan or sketch design for such a guillotine, I have posted a concept drawing onto the Fluidyne Archive - www.fluidynenz.250x.com to illustrate the principles. With all the engineering expertise within this group, it would be useful to work out the optimum pivot positions to obtain the maximum cutting force. I'm sure this would assist Paul with his Mozambeque project, and may assist others to resolve fuel preparation problems. Please don't send me the information, but post it to the list for comment and share the knowledge.
