    keep the liver completely filled with alcohol residue. This will block the liver so new chemicals can't enter.
    I see you have met my Doctor, Dr. Feelgood....
    On a serious note that actually is true for methanol poisoning, ethanol is the antidote for methanol poisoning, it blocks the methanol from entering the liver.
    Hence why a responsible biodiesel brewer such as myself must imbibe in a brew or two before getting to work on a batch...
    Cheers,

    YUP. I always thought it was 1,1,1 also. Trichloroethane is not the nasty stuff, trichloroethyleneis. But often gets a bad rap cause folks confuse the two.

    http://en.wikipedia.org/wiki/1,1,1-Trichloroethane

    http://en.wikipedia.org/wiki/Trichloroethylene

    Trichloroethane is one of the best solvents out there for when you want something very clean. Vapor cabinets are an example.

    Trichloroethane was banned from production due to its ozone depleting qualities not due to heath issues.

    Rapid Tap, made by Relton stopped using 1,1,1 in the early 90's. http://www.relton.com/relton_story.html

    Just so happens Relton makes one of my favorite aluminum cutting fluids, "A-9". The one in the green container.

    I dont use rapid tap anymore. I use Tap Magic and add my own "magic". I have 30 gallons of 1,1,1. I spice up the Tap Magic with it and lemme tell you!! It works great.



    I dont pour it on the ground, dont vaporize more than I need and dont let it touch my skin. Oh, and stay outta the fumes just like any other poison.

    Dont get me wrong. Its still a poison, but so is gasoline. Thats why I dont drink it

    More info on 1,1,1. http://www.toxipedia.org/display/tox...chloroethylene

    One of my favorites for tough stainless steel is Castrol Moly-Dee. Bought a gallon of that. Smelly but once you try it with a really tough metal you will wonder why you weren't using it all along.. JR

    It probably was 1,1,1 trichloroethane anyway. It used to be in all the cutting fluids but was banned by the Feds years ago. I used to work in a plant that made it. Millwrights working on a compressor or pump always had a bucket full of it on site for degreasing and general cleaning. It is one of the best degreasers ever made and worked super in a vapor degreaser. Whatever made it a good cutting fluid was kind of a mystery. The machinists all used it straight for hand tapping.

    Old hat, to prevent trichloroethylene, or other harmful chemicals, from getting into your liver you have to keep the liver completely filled with alcohol residue. This will block the liver so new chemicals can't enter.
    I think you've found the answer

    I have to make a living too often drownd in collant doing horizontal work.
    I work dry when ever and where ever I can.
    So......
    Same here for sulfur based for spot-oiling. I also like pastes and solids, Anchor Lube comes to mind.
    And the blue stuff, comes in soap-bars or paste. ? AcuLube ?

    I only use it for very special jobs. I use the Ridgid cutting oil on all other drilling, cutting and threading jobs.

    I think many remember how well it used to work when it has the bad stuff in it... and the word of mouth never dies. I agree about today's stuff - no better than many other products, but I like the smell!

    I bought Rapid Tap to see what so many people rave about. Not impressed.

    I find Ridgid cutting oil works better. It does stink, but not a problem unless I have to wash up and comb my hair and deal with polite society.

    For small taps and dies, castor oil works better than either. And just recently, I found that using neat's foot oil results in the lowest threading torque of all.

    Okay, so riddle me this. Will the remaining brown finish prevent or cause rust. I dont like the brown finish but it does wipe off, so its not that big of a deal. I however dont want to find that it eventually rusts parts or tooling. If so ill switch to something else.

    I havent been using it that long but noticed that my drill chuck and lathe handles turned brown and I couldn't figure out why.

    I use it often. It won't cause rust. Probably won't prevent it any more then a light oil will.

    Yes, but it hasn't been in Rapid Tap for a decade or more, maybe 2.
