    What type of epoxy or bonding agent does everyone use to bond 2 pieces of acrylic together and where do you get it?

    Weld-On. It comes in various numbers representing how thick it is (i.e. either the consistency of water or the consistency of molasses). I have some that I'll let you use, but I'm not really in your area. You may want to ping B-Rad, but I think he orders most of his stuff off the Internet. Any local place that sells acrylic sheets should have it available.

    B-Rad is the person to ask. I will give it a shot since he taught me what I know and I have done some of my own work.

    Get Weld On 4 and 16. get some syringes and needles from Farm and Fleet 18 gague will work down to 14.

    Now first use the 4, its really thin. Do not put the pieces too close together, you will get a dryt bond. leave a slight gap, paper then. The weld on will fill this gap. Do not mess up because once bonded its on there for good.

    Then use weld on 16, its thicker, but this is just a back up incase you missed any spots with 4

    We sure are.  Just picked up the acrylic so now we need to figure out how to put it together.

    Not to get off topic but that may be a great time to do it.  There may be others who would be interested in learning how to do it also.

    OK, I'm here, How much work are you needing to do? Are you just gluing two pieces together or are you trying to build a box?

    We are trying to build a box.  It would be 36 X 6 X 8. 
    What does everyone use to cut their pieces?  Have read of people using table saws, routers, etc, what gives the best results?

    You can use either, but if you are going to use a table saw get a blade with the most teeth you can find. You have to cut the pieces pretty fast compared to wood. It is real easy to heat the acrylic up to where you will have small cracks just from cutting it.

    To cut pieces with a router, a router table is almost a must unless you are skilled with a router. The slightest 1/16 of an inch off will be dramatically noticeable when dry fitting the pieces together.

    Same with sanding the edges, be careful not to create too much heat. With sanding it is hard to keep the edged flat and square and not to produce a slight rounded edge when the sand paper gives in the the pressure putting down on it.

    I have checked my settings and indeed it was set to friends. the thing about that is i didnt do that, and these people were able to send me messages prior to the update. That said, everyone may want to check their settings as well.
