--- Quote from: tomrux on January 22, 2015, 02:21:17 AM ---"Methanol is also a significant ingredient in napalm" Ahhhh no in aint. "napalm" is a contraction of Naptha and palm acid. 2 thickeners added to petroleum to produce napalm. I don't know that Methanol would be energetic enough to be effective in this use. --- End quote --- Methanol was also used to "thin" napalm for certain "deforestation activities" in Vietnam. Although I did not know it at the time, I worked on the dispense nozzles for that program. The program was "covered" under a USDA contract that, supposedly, was to aid in lighting "controlled back-fires" for fighting wildfires. I later saw the equipment loaded on C2 aircraft... |

Cool stuff guys. That's why I love it here. :D That makes things cheaper as I have a sheet of alloy so just need some bar to make the neck from :) |

A friend of mine used to fly F1C model aeroplanes, which use methanol and oil, about 80 to 90% methanol and the rest castor oil. At one point he was using machined al. alloy tanks, probably 6061 T6 or one of the 2000 series. After a few flights he noticed a black sludge coming out of the tank when cleaning the models. He switched to Delrin.......... cheers Bill |

He explained that anodised aluminium is very fine with nitro methane, but plain is a bad call. He mentioned sludge too. Pekka |

Might make up a small test tank and fill with the mix and see what happens then |
