Picture of Cutting PVC In A Tight Spot
I used a vise and a couple of 2x4's to simulate a hard to reach pipe. As a plumber I encounter this a lot. They do make a cable saw for this but, they don't last. I'll show you a way you can cut it easier than a cable saw.

Step 1: Get Nylon String

The string on the left is nylon . It's very common string. The string on the right is not nylon it's cotton and will not work.

Nice. I was expecting some over complicated solution and had the rebuke fully loaded. You proved me wrong! :) Now... off you go and find me a solution to cutting cast iron pipe in the same situation. ;)
You just do the same thing, but with DuPont carbon nanotube superstring. It's easy to get if you have a time machine; ordinary hardware-store stuff in 2215. Oh yeah, if you DO try this with nanotube string, you have to wear Wells Lamont Titanium Fiber gloves, get those in the same place. As I said, ordinary hardware store stuff in 2215, but beware, 200 years of inflation will give you sticker shock!
LOL!Just reinstalled the app on Android and seen all my messages... this is the one that made me chuckle the most! Sorry for the ridiculous delay... proof, if its needed, that I never did find that time machine! :)

Ha ha! It DID work a bit like a time machine, I had totally forgotten this comment :-)

That was crazy! Had no idea it would work.

Wow, I had no idea.
And I have been cutting things for 60 years.
Thanks for the education.

I do everything with a iPhone or iPad. Haven't had luck posting YouTube videos to instructables with those. However, yes 20 seconds on 1-1/2" pipe. Longer with larger pipe. If the pipe is wet it might take slightly longer (cools the friction). I'll tell you this as a plumber I do this all the time.
Is it only in 20 seconds?

I first tried this with neon string used on job sites as pull strings / marking string.
It didn't work with masons cotton string.
Kite string is nylon string which I referred to as waxed. It's nylon :)

No the package won't say waxed. You are correct. It is nylon string. Cotton string doesn't work because it has too much friction and won't glide. If you force it; it will just break. Nylon string slightly melts and takes on some of the pipe; and so it builds friction and heat and melts the pipe while maintaining its strength.

It does work with ABS too :)

I'm guessing you would want to use cotton string (waxed) as cotton resists melting etc due to the heat generated.

Great Tip. Thanks for sharing. Question: It looks like the string on the left is nylon and the string on the right is cotton. Is the term waxed string printed on the item packaging?
Another great tip, thanks!
