Cutting my soil pipe. Can anybody help?

[slowmotion]

Recipricating saw is what I would use. Something like this but with the correct blade for the job.

I should say that I do not need many excuses to add to my tool collection.

Failing that I would go as far as I could with a multi tool and finish by hand, I would have a large circlip wrapped around the pipe as a guide whilst cutting.

I can't justify yet more tool acquisition. My habit is already out of control. A recipricating saw does look rather handy though.

Something like this would do the job I'm sure. I have one and providing you let the tool do the job and don't force the issue it can cut very accurately in confined spaces.
There is a tendency for the blade to 'drift' a bit but the way to deal with that is to mark exactly where you want the cut and again, let the tool work at it's own speed.

Edit: Mrs Colly was just nosing and asked:'How would the blade get to the back of the pipe?'

Not a daft question but the solution is to cut out a section of the pipe to enable the tool to get to the far side. You're going to lose 400mm plus so there's plenty of room.

@slowmotion if you are near Warwick you can borrow my recip saw. They are very useful and not hugely expensive.

Angle grinder 4 1/2 " you will only be able to get so far ... then finish it off with a good hand saw .

I'm veering towards this. A full-on assault using a diamond-tipped steel blade in the angle grinder, probably guard-less, followed by some rough stuff with a hand saw, padsaw, of hacksaw blade. I 'll try and cut about 10mm short of the final line. Then stick a 36 grit abrasive disc in the grinder and finish up to the line. Then chamfer, grease, and...


....bish bash bosh!

That's a very kind offer. I'm down in London unfortunately.

If you don't want to buy one you could always hire one. Or, like I did with a cement mixer. Buy one from Gumtree or somesuch and when you have finished with it.............................flog it on Gumtree or somesuch. I even made a fiver on the deal.

Scene from Only Fools and Horses ?

I have had to un-plumb the bottle trap from the bathroom basin many times. Every time I have poured the water from the trap back in the basin to dispose of it.

Cut it with the grinder as far as you can. Then cut out a 200 mm coupon out of the pipe you will be scrapping. remark the line on the inside of the pipe and finish cutting from the inside as it were.

I have done that, despite have 10 minutes before been laughing at being told the same story. Was then handed the bowl of dirty water, then completely forgot.

I like that. The good thing is that I have 460mm of pipe to butcher to get the job done and to get access. I suppose it's rather like a lumberjack cutting a wedge in the trunk to get to work with a chainsaw. I'm not quite sure what the stuff coming out from the inside of the soil pipe will be like but there is a shower in the room below and I can always wear a pair of sunglasses for protection.

If you're using a disc cutter you want something better than sunglasses as eye protection, even if it is a pvc pipe that you're cutting.

Good point, but I'm not subject to PPE legislation on this one. Some people hereabouts don't wear helmets and ride very fast down hills.

This is exactly the tool I have got and it is amazing. You don't know what job you will use it for when buying it, but once you own one you will find all sorts of jobs that it is brilliant for and will then wonder how on earth you ever got by without one.

I've also got a 9" disc cutter which I hate using because it is so dangerous to use but it is the only tool for some jobs. Cutting that waste pipe is not one of them...

You don't get a second chance with the eyes though. Plus you've what's inside the pipe to consider.
