Suppose you want to cur tin sheets lengthwise, an angle grinder cutting blade is too costly, especially if you have over 100 sheets to rip into halves.
So you use a stainless steel braided wire, the braids act like dull knives, place it under the sheet and with a handle you pull the stainless steel cable upwards, cutting the iron sheet.
@off_grid_living It took me a bit to understand the mechanism and interpret the photo, but this is a homemade rope saw, I'd say. Very cool! Your skin was quite hard to distinguish from the rusty metal, it just blends very well with the background, so at first I only saw a sheet of metal with groks on it. Even the groks I first confused for some knife blades. ;-) How thick is this sheet metal? These guys make for some rather nice looking raised beds.
Yes homemade rope saw made from stainless steel wire and cost me nothing. In total I have cut lengthwise over a hundred sheets of roofing iron, without a cost to myself.
@off_grid_living Very nice. How long does it take roughly to rip one sheet in two?
