Jigsaw blades for perspex

[#1]

It's been a while since I have done any DIY but my daughter needs to replace the perspex glass in one of the internal doors and needs to cut the perspex sheet to size.

Should a special blade be used? If so can anyone offer some recommendations?

Thanks.

I've used these people to supply and cut plastic to size: http://www.theplasticpeople.co.uk/product/cut-to-size-clear-polycarbonate

Bosch do a Multi purpose blade but you need a Fine teeth for best results

Cheers. It's a Bosch jigsaw so now I know what is needed a trip to Homebase or B&Q should find what I want.

From experience any fine toothed blade should do, just make sure the perspex is well supported and and held down on either side of the cut, do not go too hard at it, as any jamming, jarring or jerking of the blade could cause a crack, (of the damage type not the wise).

I have also used a hand grinder but you must go steady with that, as the cutting disc can melt rather than cut through the perspex.

Rather than a jigsaw, if you are not sure (and those blades can be expensive) and assuming it's a straight cut and not a lot of it (two sides as the most?) - consider using a decent handsaw.

I did some last year for the greenhouse with no problems and getting a nice straight cut whereas my jigsaw even with the right blade tended to drift off... and even melt the perspex! A lot depends on the thickness of the material of course.

Good luck
