  • Cut 25mm steel - no sparks.

    I have a job to cut some 25mm steel plate, but I can't make any sparks. Current method is to use a reciprocating saw (which doesn't really fullfil the 'no sparks' rule but comes the closest) and a lot of effort - not to mention blades. Hand/portable tools only so waterjetting is out. Portable cold-cut saw not allowed either.

    Got about 60 metres of it to cut. Any ideas folks?

    Port-a-band sounds like it fits the bill!

      Hydraulic nibbler? Although I am not sure I have ever seen one that can handle 25mm.

        Forgot to say - I only have access to one side

          How many years to you have to get it done?

          Is there a restriction on sparking because of what's on the other side, or because of what's on your side? Perhaps you could make a partial cut with some tool/blade that makes sparks and goes much faster, then finish the cut with a non-sparking method.

          Can you use flood coolant to kill the sparks?

          What in the world is it you're cutting up? An old ship's hull or storage tank?

            Yeah, this is starting to sound like some sort of riddle.

            Unless you're trying to steal a bridge, and can't afford to make any sparks that might be seen by the police, I'd just pass on this job; too many restrictions, already.

              It's a large diameter flue in a facility which has a site-wide prohibition on spark-producing-methods. Haven't been there yet but as I understand it they have a good amount of ethanol being piped about the place.

                A pox on you if you're going to do anything that facilitates the production of ethanol that'll be added to gasoline.

                  Use a hydraulic or pneumatic powered magnetic drill and chain drill it.

                      Diamond wire sawing is my trade

                        One of the evolution saws ought to cut it. They run slow and they, for the most part, dont make sparks.

                          I do believe they have tried one of those. I'll find out tomorrow why they aren't using that, perhaps the 25mm is too much for it?

                            I bet it goes through blades pretty fast. Bet its pretty slow too.

                              Another vote for chain drilling.
                              I just need one more tool,just one!
