Cutting up old galvanised water tanks
I need to remove two old water tanks from the loft. One redundant one up there was bad enough, but now we have a new plastic replacement so there's two of them up there doing nothing. They won't fit through the loft hatch. What is the best way to cut them up? I don't fancy doing it with a hack saw! I have a 9" grinder with some thin metal cutting disks. I also have a cheap jigsaw and some metal blades (I think). I'm guessing the grinder is easiest and fastest. How safe is it to cut up the tanks with an electric grinder in the loft space (sparks)? Is it viable to cut it up with a jigsaw? Any advice very much appreciated. Thanks. |

I'd be inclined to have both available, start with sabre saw but use angle grinder to separate parts. |

A jigsaw would just about hack it, but I would go with the angle grinder. To contain any sparks hang old curtains or bed sheets which have been damped around the area. Get someone to watch for possible signs of fire, you can't do both and have an extinguisher to hand ready. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

If you do you can store small items in it and protect them from damage easier |

Thanks. I don't know how I missed that. I liked the suggested fire precautions: Wouldn't using anything electric create quite a lot of heat and shards of hot metal? Not if you keep it full of water while cutting it up. g |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Newshound" saying something like: The consensus was sabre saw first, angle grinder second. I'd be inclined to have both available, start with sabre saw but use angle grinder to separate parts. It'd need to be some sort of **** to use an angle grinder on steel, in a dry dusty loft space. |

I couldn't believe that was suggested the first time around and now it's been wheeled out for another airing. Many plumbers can't get insurance cover for soldering in lofts because the incidents of whole- house conflagration are innumerable. I wouldn't be seen dead using an angle grinder on a tank in a loft, so to speak. A cheapo Black and Decker jigsaw and a packet of blades reduced mine to manageable segments; cut into 4 parts I seem to recall. The rivetted construction looks like armour plate but they are less formidable than they look. |

Now that I've got a hatch big enough to take a tank, I want to leave mine in - being plastic, it's a good 'box'. -- Peter. You don't understand Newton's Third Law of Motion?

It's not a Herculean effort to cut mild steel water tanks, especially if attention is paid to putting a line of oil along the cut. Might well get away with 1 cut along the centreline. Quite likely. |

Bolt cutters are diagonal nippers, not bypass shears, so they're a bit rubbish for long cuts in sheet. If it's the usual thin steel sheet and a pair of Wiss snips, then rather you than me. In that case I tend to favour a hacksaw for the angle frame, then an axe (4-6lb, not a hand axe) downwards through the sheet. |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Andy Champ saying something like: I have actually seen the remains of a large water tank that had been cut up by a gas axe. You can tell by the melted metal trails. This was in the loft of a Lutyens mansion - removing the cut up pieces was obviously a step too far - and the mansion is still there. So what? Just because some stupid arse got away with it is no reason to in any way recommend it. |

It's true you don't want to breath welding fume from galvanised material, I'd have said the problem is much less with grinding, especially wearing a reasonable (or even a basic) dust mask. Fire is another hazard. Sometimes you have no choice *but* to cut them up in restricted spaces. |

Sure, but you are much better off using an air powered cutter with a scissor action than an angle grinder for that. Hire one. |

Brian Usually only the edge reinforcements are thick A decent hacksaw and then shears or a nibbler on the panels. It might even fold up if the egde is cut in the right places. |

Quick and easy to use. No sparks. Your old galvanised tanks were made from sheet on angle iron. So you are going to hacksaw (twice) through something like 20 mm angle, 4 mm thick, to give the nibbler access to the sheet. Or you stick a mask on and bang through it all with an angle grinder. I'm not sure I would want to use a 9 inch grinder with thin disks, though, but I would be happy with a small one. A decent jigsaw would do it as well, as would an Evolution circular saw with the "all materials" blade. One of these wouldn't be much more expensive than a hiring a nibbler, unless you actually live next door to a hire shop. http://www.ebay.co.uk/itm/Evolution-...AOSwTuJYtZq 7 One of my lads was recently cutting up sheeting from a shipping container using a fairly good jigsaw. It wasn't fast (or accurate). I'd told him several times to use the Evolution, but he didn't believe me. I had to demonstrate, eventually. |
