gluing acrylic?

If you use Super Glue the first time you put any pressure on the joint it will probably break. Use Weld On #3 or #4. This will give you a secure joint and will not fracture.
The #4 is a bit slower and will give you time to work where as the #3 sets up pretty quick.
Use the pin method to set your joints and you should be fine.
