Question Mark I am almost done with my own processor and I used copper fittings to connect the hose to the plastic barrels. Is that going to be a problem?

We just built a processor this weekend similar to Dale Scroggin's 'touchless' (out of a water heater tank) but haven't used it yet (actually it was supposed to have it's test run yesterday but we're on a generator at the site- and the generator had a plugged fuel filter due to bad petrodiesel a while back! so we had no power to heat with yesterday. talk about frustration). We built this system in a class I'm teaching and it was a good opportunity to teach all kinds of basic skills stuff- and very quick to assemble. The processor we built took about 1 1/2 hours to construct, and about three trips to stores (including harbor Freight) to buy everything. I have a salvaged vacuum pump but we didn't install that yet mostly as I"m having trouble finding appropriate fittings to build the condensor (like dale's condensor). For a good writeup of the type of condensor that dale seems to be using, see the recent Home Power magazine article on homemade counterflow heat exchangers (might be in current issue). that heat exchanger is copper- so technically not suitable for rrunning biodiesel through (copper catalises breakdown of biodiesel in the long term), but fine for methanol recovery. Like all my small processors, we're using HDPE carboys to mix methoxide in- using 'methoxide the easy way' system from journeytoforever. The carboys have an extra set of threads in the lid that allows a hose barb to be screwed in, which lets them be plumbed in line with the pump which allows a very good mix if you meter in the methoxide slowly (there's gravity feed involved, so they are set up on a shelf above the pump level). (this info is all based on other designs I'm already using, not just the newest one we just built) I'll keep you posted if I learn anything new from this project. Please note that Dale quickly gave up on trying to wash in the same tank as he processed in- for good reasons. Use a separate wash tank. Mine are made out of barrels. mark --- In biofuel@yahoogroups.com, "rodneyhadley" <[EMAIL PROTECTED]> wrote: > I am a Science teacher in Kansas City.
