Kevin,

    	Natural gas will be suitable for most of your needs with the
    possible exception of casting and even that if you get a high
    pressure line or compressor. When you set up your system make sure
    to have a check valve placed on the natural gas line between the
    torch and the gas supply so that any blockage in the torch nozzle
    will not allow oxygen to enter the natural gas line because the
    oxygen will more often the not be at a higher pressure than the gas
    line and can force its way back down the line if the torch tip
    becomes blocked for any reason, that can cause a fire or worse. 

    	 For safety reasons you normally want the gas and oxygen pressure
    to be the same so that this can't happen but with natural gas you
    will have a low pressure line and most oxy regulators can not be set
    to operate reliably at as low a pressure as the gas line. --
