Hi Mate,
Just an extra to wat Heavy mentioned,but if you visit the local hardware store, buy a tube(comes with a pointed nozzle) of construction glue.For a few extra $'s you can get yourself a gun that you insert the tube in.
Construction glue is great for bonding ceramics but also can be used to glue decorative wooden edges to your diorama's etc.The benefit of having a gun is you can control the amount of glue you wish to use by squeezing lightly or harder on the trigger.The construction glue is also alot stronger than white glue.Anyways,good luck with the build!!
Cheers,Shay
