Greg makes a good point. Getting nice clean bubble free joins in acrylic is not for the faint of heart. One trick is to glue them with extra material proud of the joint then flush route to get a clean edge. You then flame polish the cut edge (you'll need a hydrogen/oxygen torch for a good clean polish) but only after letting the joint fix for some time. When done right they look great, but it seems bubbles can appear after some time. Dichloromethane is a good solvent to bond the acrylic together, but use in a well ventilated area....
