Ok, thats pretty big. Just a curious question how much does a piece like this cost?
The cost of the materials is not that much, the real cost comes from time and effort I guess.
The MDF base about $5 AUS
The Polystyrene about $40 AUS
Balsa and hard wood used so far about $30 AUS
Foam Core about $10 AUS
Glue about $10 AUS
then there will be flock and basing materials including PVA about $25 AUS
Other bits and Pieces, chain for Drawbridge, Plaster for walls etc about $10 AUS
So about $130 AUS in Materials (and that's probably a High Estimate)
Add in time and effort and the price tag raises to around the $400 AUS mark.
