The first thing you need to bend acrylic is an acrylic bender. You can buy one for 200 dollars or you can build one. I suggest building one since it is a lot cheaper. I built mine using a heating element strapped to a board. All of which I purchased at a local supplier.

The element sits between two boards that are attached to a main board with a gap between. The element sits about 1/4" down from the top surface of these boards. This way you can heat the plastic without melting it too the element. I covered the boards in tin foil to help protect them from the heat and also to reflect the heat more toward the acrylic.

Here are links to Two different kinds of Plastic Benders. Here is a fancy one that will work better but cost too much. This Heat Strip is the one I used. It comes with all the directions you would need to build the wooden base.

what I am bending here is a MB stand for my Martini Mod. I used an old MB tray from another computer and I want it back to use. I also wanted to clean up the wires in the Martini. It has been suggested that they were a mess and I have to agree.

Here I have selected a 1/8" thick piece of acrylic. I made sure it was cut to the length of my MB and extra wide for the folding I would be doing. I gave it 3" on each side. I then took off the paper protection and drew on the acrylic where I was first going to bend with a wax pencil. I wanted to bend at a right angle so I also got a section of aluminum angle from the shop to use as my angle. You should also drill any holes you want to have at this time. It will be very difficult to do so after the piece has been bent. I did not do this and had to actually do this same project twice.

below you see me put the piece on the bender. To get a straight bend you want to line up your wax line to the center of the element. Within a few minutes the acrylic should get soft and bendable. You then want to take it off and set it immediatly into your mold or position you want it to set in. It takes only a few minutes for it to cool and become hard again. If you don't get it where you want it quickly you are basically stuck with it that way.

you basically see me going through the same steps for all the bends I until I end up with the finished project. I suggest first starting with simple bends until you get used to it. Eventually you can bend as complex shape as your imagination limits you to.

Just in case you were wondering "what the heck is he making?" I included some shots of it with the MB attached. The piece you see here is actually a second piece. I forgot to drill the holes first, as I mentioned before, so I had to make It all over again. This is really no big deal since a peice of acrylic cost around $2.00 and practice makes perfect. I attached it using regular screws and plastic washers for stand-offs to lift the MB up from the acrylic

before and after: I kinda liked it more before but we will live with it for a while and see.
I needed the MB tray anyways for a new project.
