    I don't think you want to cut plexi on a table saw.. But, yeah, if you end up doing that you can't use a normal blade.. you will shatter the plexi (or at least I think)..

    Your best bet is to scar the plexi with a scarring tool and break it that way (at least that's the way I think you do it, haven't done it in a LOOOOONG while)..

    I've never changed my blade in my table saw...I either use a rip blade or a finishing blade...

    It really smells though...I personally hate the smell...its gross...

    i have cut plexi glass with a table saw and it worked very well...cut it like butter.... but if you are doing straight lines you put a metal ruler on the glass where you want the cut and run a sharp rasor blade along it a couple of times and then break it....that works.

    Will that work for 3/4 in plexi?

    its scoring...not scaring ! anyways you could score and break that, but it would be hard.....table saw will work fine, they make acrilic blades for circular saws that they sell at home depot, i have a radial arm saw that i was able to mount the 7.25" cirular saw blade on....if you cant mount it on the table saw, put it in a circular and set a jig....the blades work really well.

    If anyone is interested in bending it its very simple, i havent used anything bigger than 1/4" though. WE have some bare wires under a peice of leather type stuff(not really leather) and it bends it realy fast with some coaxing.

    That works up to 5mm or so...

    Now, tell me how you'd snap off 3/4" plexi?

    I tried using dremmel, jigsaw, etc... all of'em messes it up... what I did was cut it with a jig, then sand the plexi slowly with a fine sandpaper... Oh, and when cutting, make sure you use lubricating grease specifically for jig cutting...that'd help a tad...

    Bending Plexi... if it's a small cylindrical plexi, shouldn't have much problems with a tub of hot water... but with thick plexi, never tried... I remember seeing somewhere that they had to make special vaccumn contraptions just to get the bends in the plexi...

    update me should you find out how~

    If you have lots of blades marks from the blade of the jigsaw/bandsaw, next time try a fine file to remove them first, then take the sandpaper(180-220 grit) and it will polish things right up.

    Is it hard to cut with a table saw?
    It cuts like nothing.
