ziplex Posted February 8, 2011 Report Share Posted February 8, 2011 I need to cut two old copper water pipes potruding from a wall with limited access, can't really get a hacksaw in there......i've dug out the angle grinder but I can only find a stone cutting wheel, will this do the job or am I likely to knock my teeth clean out All the gear............no idea!

mossy835 Posted February 8, 2011 Report Share Posted February 8, 2011 i would get the right one for the job. Quote Link to comment Share on other sites More sharing options...
Ian750 Posted February 8, 2011 Report Share Posted February 8, 2011 Mate I really wouldn't do this, copper is very soft and your stone disc will snag on it something awful, even if you get as far as bludgeoning your way through it you'll have shards of bloody hot copper flying all over the place. Even metal cutting discs drag on copper so a stone disc......... Quote Link to comment Share on other sites More sharing options...
guss109 Posted February 8, 2011 Report Share Posted February 8, 2011 A stone disk should be fine as they are used for cutting lintels ect as they have steel rebar in them. But remember your specs and make sure the guard is on Quote Link to comment Share on other sites More sharing options...
RC45 Posted February 8, 2011 Report Share Posted February 8, 2011 You can get discs for aluminium, might be better suited to copper. Quote Link to comment Share on other sites More sharing options...
paulf Posted February 8, 2011 Report Share Posted February 8, 2011 Just take the hacksaw blade out the frame and use it holding it in a glove, almost certainly easier than using a grinder. Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted February 8, 2011 Report Share Posted February 8, 2011 a stone disc will work on metal too, copper pipe wouldn't be a problem. Quote Link to comment Share on other sites More sharing options...
Spaniel Posted February 8, 2011 Report Share Posted February 8, 2011 Not to panic PWs, if i hear a Bang tomorrow, i know he got his water and gas pipes mixed up I would try to get in there with the hacksaw as mentioned just using the blade etc, good luck Quote Link to comment Share on other sites More sharing options...
ziplex Posted February 8, 2011 Author Report Share Posted February 8, 2011 It's really hard to use a hacksaw or just a blade as the pipes are coming from a side wall and need to be cut back in a little as I need to plaster over after they're out.....looks like the old pipes that were used for a back boiler many moons ago. I can get the right disc if needed tomorrow but i'm impatient to get the very last job done on the fire place opening......just not keen to knock any fillings or eyes out Quote Link to comment Share on other sites More sharing options...
Spaniel Posted February 8, 2011 Report Share Posted February 8, 2011 Duncan what about a pipe cutter would there be enough room to get one in there, not that i have ever managed to get on with them myself Quote Link to comment Share on other sites More sharing options...
Dorsey Posted February 8, 2011 Report Share Posted February 8, 2011 How much of the stubs are sticking out? if they're dead and your walls are good and you're plastering anyway - just beat them flat/in with a hammer Failing that a nice little slicing disc for a couple of quid is ideal for this kind of thing.

About 12" so need trimming back first....... ......Ian a pipe cutter would be a bit of a squeeze Edited February 8, 2011 by ziplex Quote Link to comment Share on other sites More sharing options...
Chris Bb Posted February 8, 2011 Report Share Posted February 8, 2011 Sharp cold chisel & large hammer. Any copper still sticking out, hammer it in. Sorted! Quote Link to comment Share on other sites More sharing options...

wingnut Posted February 8, 2011 Report Share Posted February 8, 2011 I train people all over the country to use hand held and pedestal grinders, the info you need is set out below, i hope it helps, You require a silicone carbide disc to cut copper,stone and non ferrous soft metals, Aluminium oxide discs are used to cut / grind hard metals such as steel Silicon carbide is brittle but much harder than Aluminium oxide and is used on materials with low tensile strengths such as cast iron, non-ferrous metals and non-metallic materials (STONE) Prior to use check out the expiry date on the wheel. IF THE DATE ON THE DISC (METAL REINFORCING IN THE CENTRE) IS MORE THAN 2 YEARS OLD,REPLACE THE DISC. DO NOT USE AN OUT OF DATE DISC THE DISC AS IT GREATLY INCREASES THE LIKELIHODD OF THE DISC DISINTEGRATING AND CAUSING SERIOUS / FATAL INJURIES. The disc should have pictures and a description of what you can use it for, but also it will have have a series of letters and numbers on it which should read similar to this ( british standard identification marks) C 36 T BF C = SILICONE CARBIDE 36 = GRIT SIZE T = MEDIUM TO HARD DISC BF = SYNTHETIC RESINOID MATERIAL,REINFORCED WITH FIBRE GLASS Don't forget to use appropriate ppe, Grade 1 impact resistant goggles, suitable respiratory protection, and ear defenders, gloves.

agusta Posted February 8, 2011 Report Share Posted February 8, 2011 Use a pipe cutter, one of these will do it: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260733933012 Then as suggested, hit it with an FBH Quote Link to comment Share on other sites More sharing options...
jacksdad Posted February 8, 2011 Report Share Posted February 8, 2011 I use a 9 inch grinder, but have taken the safety guard off to get more access, discs got chipped rolling round the van but I just 'trim' it down against a wall....... If you cannot get at the pipes why don't you leave them where they are? Quote Link to comment Share on other sites More sharing options...
ziplex Posted February 9, 2011 Author Report Share Posted February 9, 2011 Just to clarify......these pipes were stuck out of the side of an opened up fireplace by about 10-12", both coming out from the left hand side but very close to the back wall hence difficult to get a hacksaw or blade on them. I wanted to cut them back rather than hammer the **** out of them as I didn't want to damage the bricks anymore that were surrounding the pipes! The little 4" wheel cut through them at an angle no problem, just bent the longer end of the cut pipes over and all is well Quote Link to comment Share on other sites More sharing options...
