I was trying to make armor out of plexiglass but it cracked when I cut it. So now I have a sheet of plexiglass unused is there anything I could do with it?:cry
I've used some sort of oily stuff before to do this, through some fishing bobs. Or whatever those big red and white floating ball-things are called. I have no idea what kind of oily stuff, though, sorry. Using water, I was told, would cause rust problems or something. The oil got all over, but it wiped up, and it did keep the plastic I was drilling through from melting.

well a buddy of mine built a subwoofer box for his car outta plexi and when he was doin his cutting (jigsaw) he made me stand there and spray water with a turkey baster on the blade.
I felt REALLY dumb doin it but there was NO melting and not one crack at all.
Same principle as cutoff saws and brick/concrete.
Hope this helps.
