How to cut corrugated PVCu roofing sheets

Obviously watch your fingers! But you need to keep the sheet nicely held down to stop it jumping around.
Cut was made using a basic multi-tool. The round blades fit nicely into the grooves.
Doing it this way should avoid any cracks from occurring.
You can also use a more discrete marker pen - it didn't matter here as it would be hidden from view.

You can measure the correct length and mark it on both sides of the panel, then line a straight edge with both sides then mark it across. Will save you time marking each crown.

This is what I would have done, but then he did it this way to make a longer video.

[@hockeydad6211]

Measure 8x cut once.

[@rayrainer985]

I decided to get an oscillating tool for this purpose which does work
nicely but the problem is that it is hard to control to get a perfect
straight line. I found that using one of those thin circular saw blades
like the Diablo 5-1/2 in. x 50-Tooth Aluminum Cutting Circular Saw Blade
(I have a 5 1/2 inch) circular saw) and put the blade on backwards, so
that the tooth is not cutting directly into the corrugated plastic like you normally do for cutting wood which
tears it up. By having the tooth the other way, it cuts a nice clean
straight line, actually cleaner than the oscillating tool. I also tried a much thicker blade like this KwikTool USA BB5510 C7 Bad Blade that claims it can be used on anything but I found it too thick for thin corrugated plastic. On fiberglass, it might be ok but still use it backwards.

You can also turn the blade on a circular saw around and it will do the same thing.

[@astronomyshed]

Easier if you put a piece of the sheet above and below the one you are cutting, just off your cutting line, it gives you a guide line but also makes the whole thing more rigid.

[@NeonWatermelonJoy]

Sounds like good advice! Indeed would save you needing to mark the cutting line which will look better.

[@psychedelikchameleon]

Thanks for the video and the tips!

[@gondwanalon]

FYI: masonry blade in a circular saw works great in cutting teftex. Even angular cuts

[@archiemcberry7102]

I used the paneling blade reversed and it was perfect. A little sandpaper and ready to install.

[@markfowler9352]

Is he paid by the hour?!

[@colourcascade7600]

Was thinking the same 😂🤦‍♂️

[@AndrewHelgeCox]

Did you try any other cutting tools like a circular saw or a hand saw?

[@darralpphillips]

Mate
Mark either side of the sheet and use the level to draw the line.

[@wilwordsworth]

I just tried a normal hand saw and it shattered like I had hit it with a hammer. Not small cracks either, 3 inches lengthwise.

[@jettrink7510]

Do we have to watch each measurement ?

[@powaqqatsi8]

Just fast forward.

[@android01978]

Yes

[@doctormarazanvose4373]

measure twice cut once - or in his case measure multiple times until confidence reaches acceptable levels

[@franciscogago8156]

Muito obrigado. Deus está connosco. Agradecimentos.

[@masifkhan.]

i donot have this saw. and seems expensive to buy fora small project with one sheet. Can i use normal hand wood saw? or i have jigsaw machine.

[@NeonWatermelonJoy]

Wood saw would just keep making it crack.
A hacksaw might do the job, but won't look great.
Jigsaw might work - but not sure?

[@JohnR-vb3jo]

i used a metal thin cutting blade on a battery grinder otherwise same method worked a treat

[@jamesclarke9149]

Why not put one mark on one side another mark on the other line the marks up and draw a line through

[@martyncivil45]

lol....my thoughts exactly!

[@euclidespardo9987]

What kind of Blade was that ?

[@johanderuiter9842]

So the uploader is using a multi-tool with a blade, as it seems he didn't point this out anywhere. An plain angle grinder will also work.

[@psychedelikchameleon]

He says this in the notes on the video

[@makerofchippings2948]

Is that a Fein type tool and blade or a angle grinder type thing
You can tell I am a novice, but at 71 will have a go

[@NeonWatermelonJoy]

Thanks for checking.
It’s a multi-tool with basic fine toothed cutting blade.
A grinder would be too powerful a tool for this task.

[@customboatscreensolutions5893]

Long process m8. Just mark either end

[@xavierurbina7174]

easier.with a shock line

[@onelove9101]

Metal scissors?

[@NeonWatermelonJoy]

Nah, tried that previously. Just ends up cracking off in random directions.

[@gameoveractw]

We know how to measure!

[@michaelrpbuckley8982]

Chainsaw is best 🤣

[@martinrushent3397]

What blade is that please

[@NeonWatermelonJoy]

Any should do as long as the teeth aren't too big. But you can get ones marked plastic/metal/wood if you want to be sure you're using the best for the job.

[@thomasjeffersoncry]

Measure 16 times cut once...lol Ever hear of a straight edge or square?

[@kerryman9589]

This how bored I am watching him take for ages to cut a piece of plastic marking out .I be quicker marking out croke park

[@dougjones4987]

Wrong
