  • how do i trim sheets of acrylic?

    Posted by Iain Gordon on August 1, 2005 at 4:49 pm

    First of all, NEVER,NEVER do a job for a 3rd party without checking all the measurements yourself…..

    Now the problem….I have to trim down 2 sheets of acrylic by 200mm (lightbox front)

    1. Can it be done with a variable speed jigsaw?
    2. If so, does anyone know what sort of blade i should use.

    By rights i should just make another one and charge him again, but i’m trying to build a worthwhile relationship.

    Mant thanks

    Yes Iain, it can, a blade is available for perspex. I bought a set of various blades from B&Q Just make sure the material is on a firm surface, If you have 2 pieces to cut use one as the guide for the other.

    Use a fine toothed blade. If it overheats and fuses the perspex, put a bit of 3in1 oil or washing up liquid along your cut line.

    I would suggest to use a hand router to cut through you will get a cleaner cut edge andyou can also use a jig to help you keep straight.

    cheers

    any blade will cut it, but if you use the one designed for the material, you should not need lubrication,
    A hand router will do the job, but makes loads more dust. You can cut a perfectly straight line with a hand held jigsaw, just like a router, if you use a jig or straight edge to guide it.

    yes Iain, but see above, if its a straight cut, I would go for the jigsaw,

    Peter,
    Jigsaw it is….. going up and down with a bit of lubrication sounds good to me 😀

    Sorry, just thinking aloud there

    or, if you have a steady hand, and consider yourself a craftsman, you can actually cut it with a crosscut woodsaw. it want get you any more brownie points, but will give you a great feeling of achievement

    Cut the acrylic a treat. Used Blg G’s tip for the lubrication

    I did it with and without washing up liquid to see what the difference was and was amazed at how the acrylic fuses together without

    Glad it worked Ok matey.

    Generally speaking the ‘proper’ Perspex made by ICI doesn’t need lubricating, but some of the cheaper brands do. Especially if they are extruded acrylic.

    Hi Iain, i use a bosch jig-saw and find that the best blades are T101A0.

    I use a circular saw bench with a fine TCT blade.
    I nearly fell foul of my own bad measuring with 2 sheets of acrylic, luckly I desided at the last minute not to have the supplier pre cut the sheets for me. When I measured the job again I found I’d measured wrong the first time 😕 That would have been upsetting.

    Measure once cut twice, Doe, I mean measure twice cut once.
