De-bond acrylic?

[jimmyleg]

is it possible to un-fuse or de-bond acrylic? I want to take the integrated wet/dry out of a tank to add volume, also have a sump I want to move a bulkhead

It's a chemical weld, can't see anyway of de-bonding a joint.

A saw. Those joints are stronger than the acrylic. I did a test and bonded two pieces of acrylic together at a 90 degree angle and let it fully dry. I tried to break them apart and broke the acrylic about 3" away from the joint!
