Just a couple of comments.
Re: drilling plastic. Bits designed for metal and wood tend to hog into acrylic plastic, thus causing it to crack. If you grind off the sharp leading edge on each lip of the drill (called dubbing off) perpendicular to the face (i.e., remove the acute angle of the cutting edge), the action will be to shave the plastic and not to hog in. Only a tiny amount needs to be ground. A flat face of 10 to 30 thousandths inch is usually adequate. Of course, the bit is for plastic only after that. BTW, it also works with brass, which also tends to hog in.
Re: cementing plastic. Chloroform works, but eventually leads to crazing of the plastic. Liquid adhesives available for the purpose have substances added to reduce crazing at the joint. Acrylic is easier to cement than polycarbonate.
