Get a diamond tyle cutting disc they are cheap at bunnings after you use one you wont want to try any thing else they are good for all type of plastic pipe to
I have one set up all the time wouldent be without it

I would agree with F&F, those diamond cutting blades are great for plastic of all types especially PVC pipes. I personally used a metal cutting blade in a 4 inch grinder for the metal frame which would have been better with 9 inch, and then a resipro or saber saw for the plastic, hard to control but very quick and easy.

You can get an almost worn out diamond blade [ideal] at a garage sale for 2 bucks

I just used a timber power saw, cut hole in each corner with holesaw draw lines, set the power saw for about 20mm cut. Hold tip of saw on plastic, lower slowly and away you go. Clean up any rough edges by running the edge of a file along them.

+1 for the 100mm angle grinder. Cuts easily and doesn't leave plastic bits if you use a metal blade.

Yep... angle grinder and a used diamond blade for me as well....

+1 go the cirq saw

I ended up using the metal cutting blade in the angle grinder for cutting through the cage and the plastic cutting blade for the angle grinder for the liner. They worked well, I was showered in sparks and then in plastic snow.
Should have taken off my wooly jumper before I started though!

I was in a pinch and used a gas chain saw. butter.

I used a good old wood saw...

A diamond blade

6kW Blue light laser, not even a hint of sharp edges when done.

5" angle grinder with a miller blade. Also covered in snow. Would not recommend to people without lots of experience, think circular saw blade spinning at 12500 rpm, without the guard that covers it automatically.
