i need to cut up few large pieces of sheet PVC, 1.5mm thick.

Too thin for a saw, too thick for scissors. wha’ts going to get through it?

stanley knife?
tin-snips?

steel rule and stanley blade, assuming you’re doing straight lines.

How in neat does it need to be? You won’t get through it in one pass with a Stanley and it will be easy to slip off line even with a steel edge. Tin snips will cut it but might be a pain on a big sheet.

I’d go with a jigsaw and a fine blade possibly on a bit of sacrificial timber to support it.

I would have said use a fine toothed saw with something solid against the edge

Vey fine bladed pull saw will do it.

Stanley, first pass score it, second pass quite gentle cut on score line that now acts an extra cutting guide then final cut. Use sharp new Stanley with retractable blade and set it right in so you don’t slip and slash your leg….

Thanks. I’ll try with a stanley knife. I’ve got a bit of spare for a couple of failed attempts…

Slight hijack sorry, best way to cut 6mm polycarbonate sheet is…..?
Might need to trim some offcuts for some windows in the mancave.

6MM poly I cut with a jigsaw when fitting new panels in bus shelters

Cheers which blade do I use, cant remember which ones I got with the saw?

I used a wood saw blade make sure it is newish and do it fairly slowly or it melts the plastic .I found this out on site with a knackered blade luckily the cut edge gets hidden !

Sharp Stanley blade and it should snap very easily.
I regularly cut sheet aluminium the same way.
Edit:- Not for 6mm tho, jigsaw or circular depending finish required.

I cut a cat flap in a sheet of 8mm with a jigsaw and it re-sealed behind the blade as the blade friction melted it. Took several attempts to actually make a cut which stayed cut!

Angle grinder an option?

Granny-ring,where are you based?

For PC an angle grinder is not a good option. It’ll melt and give a poor finish. You really want it to work the material a little so the bits come off in reasonable sized chips. Slower moving blade (like a jigsaw) will be better and try and move along the material fairly quickly.

I recently used a bosch multi tool and a straight edge to cut some upvc, worked well and pretty neat finish

best way to cut 6mm polycarbonate sheet is

That’s another aspect of the same project.

Jigsaw, with a fine blade, fairly fast with pendulumn set to “1”, whatever that means.
Worked a treat.

Not got around to the PVC yet..

Will give it a go later in the week cheers. I’m in Kent sargey.

Whoa!!! stanleys are good but can slip no mattet how careful you are. The lads who fit wall cladding at our place (altro white rock) is similar thickness they use cordless shears theyre fast neat and very accurate. Electric scisors if you will can be hired cheaply or borrowed if you know any tradesmen. ive tried stanleys and yes they do work but id fancy my fingers being intact at the end of the job.
