Hand tool for cutting exhaust pipe
i want to have a go at making lobster bends in exhaust pipe, not for any practical use but purely because it looks interesting! But I need a method of
cutting angled cuts in the exhaust pipe.
I've been looking at things like a hand mitre saw from the likes of Toolstation etc, but apart from them not accommodating 3 inch pipe they
don't get good reviews. I also don't want a powered saw because it's a bit much of an outlay for an 'experiment'.
I tried to set up a jig with spare metal, but while I managed to get one cut done the jig ended up losing it's face so I doubt it'll keep
the blade in line for more than one or two more cuts.
Can anyone suggest how I can do it?

If you want a more permanent jig, you may want to sleeve four bolts with stainless steel tubing so the hacksaw "rides" the rollers without
cutting.
With a little wits, you may be able to make it adjustable in case you want to do different angles.
Like this, but the Pins roll...

I used the web site linked to print out templates.
https://www.blocklayer.com/pipe-miter.aspx
Wraped the template round the tube, marked with a permanent marker, and cut it with a hacksaw.
(Stainless is pretty hard on the hacksaw blade)
Worked pretty well on my exhaust. There are also templates for t joints etc which i used for my roll hoop.

Could you elaborate as how you used it to assemble your exhaust?
Thanks in advance.

I needed a small bend to get everything to line up.
You can see it between the end of the manifold and the v-band joint.
It needed to be quite short as I bought fairly long silencers and was quite tight for space.

+1 for the paper templates thing! I made a 4" bend for my air intake from the side of a washing machine by cutting out the segments drawn using
a paper template and then bending it into hoops before welding together and my chimney for my Pug V6 was hewn from stainless tube using paper
templates. Thus:
 
Chimney lobster
 
Chimney lobster flappy disc
 
Chimney lobster shiny

Well, it works...
I just need to find a bit more time to weld it up. It took me a couple of hours to make the jig, and a couple of minutes to cut the sections.
They're not particular aggressive bends for now, I just wanted to see if the process made sense to me.
