Hi Norm! Welcome to the forums! Nah, you shouldn't have to buy anything but the materials you are going to use to build it if you go that route. Then again I'm not too sure on your set up or what you want to do.
There are three or four things that can be used to glue Perspex or Plexiglass , chemical Methyl methacrylate . First is of course the makers recommended glue often a two part glue or a single part that is cured with U.V. light . Very strong Acetic acid called glacial acetic acid will also dissolve and glue Perspex . The easiest and most practical for home use is Chloroform if you can obtain it . Either soak one edge of the joint for a short time or add a little chloroform to a close fitting joint using a small glass not plastic dropper . Chloroform is not inflammable but should be used only in a well ventilated area . It is also one of the substances that with frequent use could become addictive , and of course can cause drowsiness . The bond if done with care can very strong .Ed C. said:Does anyone knowns of a source for acrylic glue? I need to glue 3 together for a safety dust featcher over the saw blade. Thanks
