cast iron soil pipe

[leslie50]

Need to cut back a cast iron soil pipe about 8 inchs, the pipe goes straight out the wall, was thinking of using a angle grinder with a metal blade, any other ideas .

Grinder'll do nicely, mate.

Thanks for your quick reply.

Grinder is the baby,tried using a junior hacksaw once ,not much good,just make sure the piece you are cutting off is well supported or all is clear below and wear goggles !!

............and ear plugs!

if you not limited to space then a normal hacksaw and good blade will cut it easy, couple of mins and bobs your uncle.

That reminds me, I'll have to treat my hacksaw to a new blade, I've got more teeth!

 

[mickie]

dont use a steel disc on the grinder

surely there is a fire risk if there is a wooden floor where sparks can go through, use a hacksaw with new blade and a 2lb hammer (dont know the metric as it will always be a 2lb hammer to me) cut the pipe till the full height of the blade is just through the pipe, then smack it with the hammer and off it will come, just mind your toes

Interesting to read people suggesting a hack saw for the task. Having fitted a lot of LCC cast in the sixties/early seventies. I think i would still be on the same job with the hack saw blades available to me.

for wood to set a light you'd have to contain the sparks in 1 spot for about an hr.. ive used grinders a lot restoring xr2 205gti ect..

obviously if you have a gas pipe open you may have problems you could try containing the sparks though

seriously you can cut a CI pipe quicker than you can change the blade in the saw if the wing nut is seized, you only cut through the pipe until the depth of the blade is through making a cut approx 40-50mm wide, then dunt the pipe with a heavy hammer, dont be shy skelping it and off it comes in one, the risk/danger is not hitting it hard enough to snap it, once shown i would rather cut it that way that carry chain cutters from the van up the stairs to do it

I used to use a chain cutter. Mega expensive and difficult to justify unless you do alot of cast work, but very effective.

I'd use the grinder, score it as much as possible, but make sure yiou have cut into the pipe, then put a bolster in it and give it a whack, I have dont this lots of times on big cast (24 inch, fire mains), it splits around the score line, nice clean break (just giving it a whack with a lump hammer can having it split all over the place)

Mind you the 24 inch cast is about a 1/4 inch thick, still be there with a hack saw

tut young boys today, soil CI is 3/16" thick, wait till tamz reads this he will be slagging you all as well

908 gram hammer doesn't have the same ring to it does it? and a 90.8% of a kg hammer sounds worse

Use a snap cutter/chain cutter and you won't get any sparks. They can be hired from tool hire places, just google it for a supplier in your area.

Hi. I have a ridged snap cutter £60-00 and it yours.

Absolute bargain, go for it mate!

What Kirk is saying here is right enough. You can cut cast with a hacksaw quicker than you could find a socket to plug a grinder in. Nobody had grinders when we were doing this stuff.

Just saw it until you get fed up sawing then skelp it with the mash hammer. It will break clean enough.
I was always a 4lb man myself

You can't do this if you are cutting into a pipe. You will need a chain cutter or a grinder or a lot of patience and big arms

 

[Blackcatgas]

Use the grinder, wear a loetard, choreograph a small dance routine to the backdrop of the flying sparks, hey presto your very own 1980s "Flash Dance" reproduction but at a fraction of the cost!.
Then post the video on here.
