I sent it in email to. Let me know if you need anything else.
Hello, here is a link to the processor plans from Murphy's Machines. They are $100 but are helpful.
Murphy's Machines - 63 Gallons BioDiesel Processor System Plans . I would not recommend using some of the materials in there however. Some of the pumps suggested could pose a hazard. If you do not want to purchase plans just model the drum design after our processor. It has been proven to be safe and reliable. I would also suggest using the pumps we use only because they actually have a biodiesel and methanol rating. Most other cheap pumps are only meant for water and will fail, I guarantee it. Please let me know if you need any more help. I would be glad to assist you. BioDiesel is a great hobby.
