There are two types of Lucite, one is 10x Stronger then Glass and comes with a plastic covering, the other is 100x Stronger then glass, and comes with a brown paper covering, if possible go with the Lucite Tuf (brown covering) if you cant afford it, then the regular stuff will work, but keep in mind if using 1/8 Inch, do not pick it up with one hand, this creates uneven pressure in two close points, and can crack the Lucite... With that said, any uneven ressure on an edge can crack it... Though ive never had this problem with the one that has the brown covering...
Lucite Tuf is the same as Lexan, may not be the exact same recipe, but drills, cuts, behaves the same. This is not true with the regular Lucite, though still good, extra precautions should be taken as it is weaker.
