Cutting Soil pipe accurately

[ToughButterCup]

My hands aren't what they used to be; so in cutting 110 soil pipe, I need to make some sort of jig to hold it.

I came up with this jig - and I'm hoping some of the nerd herd ( @Onoff's term not mine -but it's a good one) who have done this task a lot will put me right.

 

Two bits of 4 by 2 a little over 110 mm apart, fixed to a bit of 9 by 2. That in turn is screwed to the bench top (a scaffold board). It's a bit wider than 110 to allow me to grip the pipe so it doesn't turn.

My hands just won't / haven't got enough 'spread' or power to grip the pipe any more.

 

This is the jig 

 

The old dressing gown enables the pipe to be gripped a bit ...

 

But this is the wobbly result ....  maybe a different type of saw would help?

 

 

I suppose I could file the end smooth and square - I was very tempted to put the pipe through the crosscut saw: cowardice or caution --  not sure which stopped me.

Cordless angle grinder is the tool you want.

[Russell griffiths]

Use a fine tooth saw used for cutting laminate flooring, very sharp and fine, then use the pipe end bevelling tool to smooth end, look up my topic on it, or use a flap disc in an angle grinder.

Yes after nearly losing my thumb (don’t ask) I have a lot less grip. The jig is good, my only comment is make the 2x4 , 2x5 and cut a square slot in it (like a mitre block) to get a square cut and line it with rubber mat to grip the pipe.

[Russell griffiths]

If you cut an off cut of pipe neatly, then cut a slot in it you can use this as a template to mark a neat line all around it. 

 

Not it sure that makes sense, cut a piece of pipe 100mm long, then split it with a cut up its length so it is springy, you can then spread it and slide it over your other pipe and use it as a template, hope that makes sense. 

 

Or or else do as Declan said and use a 1mm disc in the grinder.

Buy a soil pipe wall bracket and clamp it on. Use that as a guide for your handsaw.

 

Or keep an offcut of pipe with a split and use that to draw around or as a guide for your multi tool.

 

Like I did on this pipe to cover the water meter:

 

 

Or use a mitre block (& Bacho saw). This is the £4.99 block from Screwfix:

 

 

Use 4 bits of 4"x2", cut dead square. 2 each side, set the saw blade width apart.

One of these cuts and bevels in one. I'm seen them a lot cheaper than this though.

Bugger me you can keep that. 

Shocking price.

@pocster will likely buy one.

A pipe chamfer tool is useful.

[PeterW]

Chop saw and a flap wheel on the grinder is what I use. Still got all my digits ...

[Ferdinand]

For a handsaw I have used one of these for cutting plastic, an Irwin fine tooth floorboard saw. £9.99 from Screwfix

[Onoff]

I tried making a pipe chamfer tool.

 

 

[Jeremy Harris]

A word of caution if cutting plastic pipe with a chop saw.  Don't try and cut freezing cold pipe this way.  I nearly lost an eye doing this - the pipe just shattered into loads of sharp fragments when the saw was part way through (yes, I should have been wearing eye protection...).

[Ferdinand]

I suppose you could use one of those hand cutting chains used by survivalists.

 

But that perhaps requires it to be held in place as firmly as a tree branch.

But bevel the end first please and use silicon spray.....

[Bitpipe]

Various ground workers I had all used petrol saws with a solid disc and did it by eye, used the flat side of the disc to do the champfer. 

 

Given the pipe slips inside the fitting and the seal is at the collar, I don't think you need to get it mm perfect.

A Bosch, anal, and lacking experience always falls back on - Das muss Millimeter perfekt sein  Junge !

 

For me, Tommy, ze vorrying is over. Jawohl !

If I had a lot of pipes to cut it would be a definite purchase!!!

Genau richtig.

[Gone West]

If you just want to save time cutting the bevel this is an option.

As @Russell griffiths use 100mm of pipe split for the straight line mark. 

110mm grinder spin pipe as cutting. Champher pipe with same grinder twisted on angle while rolling pipe.

Don't you mean a 115mm grinder?

 

(Devil's in the detail etc! ? )

 

Using a 1mm slitting disc on edge, as a grinding disc...not the best idea imo.
