    thanks guys! epoxy kinda bonds but it does not dissolve plaxiglass. JB-weld is good stuff but it's also epoxy based, and ill work on pvc and abs plastics as well as many other glues

    i spent all evening yest to drive around looking for right stuff and nothing. i think i will have to order it and wait till next weekend :/

    so far i found weld-on #4 works good from a guy in aquarium store, but weld-on products are not sold anywhere... also the best stuff is dichloroethane, it's a straight up chemical that melts plaxiglass when applied so it makes a weld bond and dries in minutes, but no luck with that either. wish i had chemist friends :P

    Poly-Glue works... it "melts" the plexi togeter, leaving only a slightly trace of unclear seethrough where the glue is.


    I have been working a bit with plexi. I always end up with screws to secure it. I realy dont trust the glue to work at any times. Specially if you have liquid in what ever you are building... (Like me, water cooling tanks and such). I allso go over the edges with either clear silicon, or black silicon... Then trimcut the silicon when it's dry.

    If you plan to use screw, get the stainless steel ones, for wood. Then drill a hole first, at SLOW rpm.

    this is the reason why i want to find dichloroethane, or something similar like weld-on #4. it does not bond plexi with as adhesive, it melts it then when u attach two pieces together u get a perfect bond. even when u try to break, the plexi glass brakes somewhere else and not at the joint

    it works like acetone when working with plastic scale models.

    ill post some pics when i finish the box, so far i have most of the stuff cut out and ready to be assembled

    What about the plastic cement used for model cars? It melts that plastic together, and might also work on plexi. You can get it at any hobby shop, and it's cheap to try, so no big loss if it doesn't work.

    All those "GLUES" are acetone based and will not disolve plexiglass. you will need Weld On #3 or #4.

    Found another supply for Weld On #3:

    I've never heard of Delvie's Plastics before but it sure looks like they have lots of goodies that a case maker might like.

    no one has mentioned this yet...and it's the most obvious and dumb question in the world...but...

    you have removed the plastic covering on the sheet of plexi right?


    as for bonding the two, I've had the best luck with plastic epoxy and roughing up the edges to be glued first. Doesn't come out perfectly clear, but has done the job.
