CA glue never sets while joining heavy, alignment- critical parts. To make the glue set, just misalign the pieces and get glue to ooze under your finger. Bang! The glue will fire off, cementing your finger to the misaligned parts! Or it just sets under your finger, leaving a CA fingerprint, while the pieces slide, then fall apart, causing more glue to flow outside the mating surfaces. Now the parts have CA glue all over the place, and the mating surfaces no longer fit due to a layer of partially cured glue. But the rest of the glue is still not set, so you have to wipe off the gunk, then chisel off the stuff that set. Rinse and repeat.
Sorry, just ranting about last night....
