I have found a very good glue is bostik quick-setting PVA glue. All the advantages of normal PVA and it will set whilst you sit holding the bits together. Takes a bit longer to fully go off mind. Also comes in a nice tooth-paste tube with a fine nozzle as an added bonus. It s expensive in comparison to normal PVA though. Our local DIY store - you know the one: Rip-Offs R Us - sells it for about £5 - £6 for a small tube. A tube is more than enough for most of my models though, and this allows me to avoid CA as much as possible, given that CA is the devil's own spittle and always goes and breaks when you least want it to; either that or I am a c**p builder? Hmmm, on reflection, that might be it.
