Cement for welding acrylic can be easily made for next to nothing out of scraps. The bonding is fast and very strong.

All you need are acrylic scraps, and acetone.

The acrylic is broken up into tiny pieces that fit into the syringe.

Acetone is added and the acrylic will dissolve. The mixture will turn into a very thick goop. The air bubble in the above picture took about a minute to go from the bottom of the syringe to the top.

Place a little dab on the acrylic you wish to join. It sets very fast and doesn't run. You can extend the setting time by diluting the mixture with more acetone.

The cement dissolves the acrylic, welding the two pieces together. The acrylic suspended in the mixture hardens when the acetone evaporates leaving a nice fillet.

Even edge joins like this are very tough. I couldn't break these apart without tools. These samples (and ready to use cement) are on the soldering bench shelf above the monitor -- check them out!
