I have this guy who wants me to build some rather large, simple frames for some old signs from a now defunct race track. I will be buying a 4X8 sheet of 1/4" plexiglass and I will naturally need to cut it into the sizes I need. I was thinking of using a very fine tooth saber saw blade. I think I have done that in the past with relative luck, but I thought I would check with the pool of experts on UJ for some handy information. I'm assuming that the plexiglass will come with a protective plastic film on both sides, and I will tape the cut lines to further help in producing a nice cut, but is there anything else I might do to mitigate any fracturing along the cut line or is there any better advice? Would appreciate it guys. Thanks
