Cutting galvanised steel tube

Wonder if there's a metal cutting disc that would fit? The speed isn't a million miles away from an angle grinder - certainly no faster. -- *It's o.k. to laugh during sexŒ.Œ.just don't point!

The message from John Rumm contains these words: Though my current 330mm chopsaw blade has gone through 20 slices of 50 x 3 square box, dozens of bits of 50x5 flat and 50x50x3 and x5 angle and is still not fully through. Is that an abrasive or a diamond disc? Abrasive. That's pretty good going for an abrasive. What brand of disc is it? -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

The wood cutter on this Taiwan effort was 210mm the nearest metal cutter I could find was 180mm at Machinemart,but it done the job and I can now cut steel pipe perfect and at right angles also. :-) -- Sir Benjamin Middlethwaite |

Cutting galvanised steel tube - steel cutting wheels

The Natural Philosopher wrote: Yes. It transforms a cheap angle grinder into a useful tool. The blades don't last for ever but they do last for a very long time. More usefully they don't wear down smaller like abrasive cut-off discs, Eventually they do.. To be fair they probably can't quite! ;-) abrasives are abrasive all the way to the hub, diamond discs usually only have a cutting edge that is at most 1cm deep and once that is worn away you are black to a plain steel disc. Precisely. |

It's lying unused under the workbench. It was simply too small for most of the wood cutting I do, but would be fine for most metal stuff. -- *Cover me. I'm changing lanes.

Otherwise (if this is going to be a habit) then the 150ish quid bandsaws (Sealey, Clarke et al) are dead handy and not too expensive. More use than a power hacksaw, certainly (I use both, and the Rapidor hacksaw only ever gets used for 2" thick unobtainium) Don't get a reciprocating saw. They cut OK, but clamping is a pain. So the results are poor, the noise is horrendous and the vibration will shake your fillings out. |

I am outside the UK this week, so that one's out. Also, the nearest one is quite some way away. Could order the Axminster one, though.

More use than a power hacksaw, certainly (I use both, and the Rapidor hacksaw only ever gets used for 2" thick unobtainium) It isn't going to be a regular thing. I don't do that much metalwork, although do do some work with plastics for jig making. I can see that the metal-cutting bandsaw is flexible which would be appealing. However, it's physically quite large, I guess, and I am not sure that I could justify its floor space in the workshop. Thought though. Don't get a reciprocating saw. They cut OK, but clamping is a pain. So the results are poor, the noise is horrendous and the vibration will shake your fillings out. Shouldn't be problems there. I don't have any amalgam ones :-) The renting a tubing cutter and pipe vice idea quite appeals, assuming it will cut through the material OK. |

Is this angle grinder territory? If so, can anybody suggest a suitable cutting wheel? Otherwise, is a more substantial saw like a cutoff saw required? I've read through this thread looking for someone to answer the question, that if you cut galvanising how to you re-seal it ? If the assembly is to be made of coated steel then there it must be required to be used in a situation where the galvanising is complete - cut it and rusting will occur. I want to build a conservatory of galvanised 2" box section steel as there is a headroom problem using anything else and if I buy it in and cut it how do I then protect the exposed ends, drill holes, etc. Rob |

The message .com
from "robgraham" contains these words: I want to build a conservatory of galvanised 2" box section steel as there is a headroom problem using anything else and if I buy it in and cut it how do I then protect the exposed ends, drill holes, etc. Buy plain, put it together (the frame, not the whole thing!) then take it apart, send it to the galvanisers, then put it all back together again. -- Skipweasel Pay no attention to that man behind the curtain. |

The message
from "Cicero" contains these words: 'Galvafroid' paint - roughly 'cold galvaniser'. Great stuff provided it hasn't sat in stock for a year or two. I had a dozen tins once which the boss told me to stir. The zinc powder had settled into the bottom and was thoroughly stuck. Took /ages/. -- Skipweasel Pay no attention to that man behind the curtain. |
