  2. I'm about to start another thread about a new type of oil they are selling from one of these Chinese websites. Its much more oily than normal oil, contains much more friction reduction technology, and will remove sludge, and resurface the bores. Its groundbreaking stuff

    It uses nanotechnology to attach itself to the cylinder walls and creates a surface with tiny domes that self-repair. The fluid that the nano particles are suspended in is basically water for cooling purposes.... so it wouldnt be oil, so we can discuss it..

  4. Re: voltage/current-

    Volts dictate how far into your body the amps go, amps dictate how much damage they do when they get there. Or Volts are analagous to how far you can throw a ball, amps are how heavy the ball is.

    50A is relatively safe at certain tiny voltages as it won't really move, just like 1000 volts is relatively safe with no current behind it- take those electric shock pens and handshake thingies ;-)

    although I definitely wouldn't advise anyone to go poking around stuff without having done the maths/seen someone you don't really like do it first.

    I have held onto 240 volts AC too many times, 600v DC once ( touched a valve anode, pressed transmit then dropped the microphone on a Pye Vanguard VHF radiotelephone as I was zapped so the inverter shut down..)
    If your hands are dry and you arent sweating over it and you dont have any cuts then mains is unpleasant.
    Its 20mA to 200mA thats dangerous through you, the upper limit is because you start burning rather than being zapped...
    And AC is slightly safer than DC as you can let go a bit easier.
    12 volts cant deliver enough current through you to be dangerous , but it can melt a spanner and burn you if you short it out, or start a fire.

    I have also set fire to a waste paper bin when I lit a piece of paper using the spark from a car ignition coil.

    Anyway dont risk it with the mains.
    And use fuses to protect wiring on lower voltages.
