    Ripping only works across the sheet. For cutting lengthwise see my post above.

    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.

    I use the scoring method for along the length cuts with a bend and flex etc, but for cross cuts I do the first couple of inches with an old cleaver (just a wack at the right place) and then the rip method described above. The only difference is the I stand on a bit of wood that is lined up with the cleaver cut, across the width, and then grab and rip.
    Only works before you put it up on the roof.....yeas I know, but I actually tried it up on a roof!!....smirk!

    we rip it down the length of the sheet by laying the sheet over a piece of wire. One end of the wire is tied off at ground level to a star picket (driven into the ground), the other end of the wire is hitched to a bit of stick.
    Line the sheet up over the wire, and pull the wire up and back. Its pretty neat when you get the right 'speed' happening.
    Can be used for cutting across the corrugations as well, if you want.
    When I first saw it I thought the bloke telling me was being a smartar$e... till I saw it.
    Cheers,

    Thumbs up

    G'day Mic-D,

    Great struff. I'll file that one away and give FIL a run for his money, if ever the chance arises to use it, and knock the socks off him.

    (being one up on him is a great thing )
    I make things, I just take a long time.

    I have ripped cor sheet by using good fencing wire. Nail the wire to a board and lay in a straight line under the sheet, with a nick cut into the sheet, then standing on the sheet, pull the wire and it cuts like a cheese slicer.

    Ive seen this done with piano wire with a clip on one end and a wooden stick handle on the other ,cut a small nick at each end of the sheet with snips ,place the clip over one nick with the wire in the nick, lay the sheet over the wire and line the wire on the other nick ,using the handle end pull up and back while standing on the sheet .Cuts like a hot knife thru butter.

    Default lengthwise 'ripping'

    My father in law (now long since retired builder) cuts corro by scoring the sheet with the heel of his hand saw (that is, the last tooth nearest the handle), and then folding it - an old brickies trick I think.

    Similar to what I do ,I use a long piece of angle iron as a straight edge and score the sheet with an old power hacksaw blade sharpened to a hook on one corner ,two or three runs then bend the sheet backwards ,and it snaps like fresh carrot.Works length ways ok on corrugated ,cutting a cross the sheet I use Wiess snips .
    I cut all my sheet metal like this up to 1.6mm as I don't have a guillotine at home .
