Cogs

Cogs on a wall .. these are just not any old cogs but the wooden masters or patterns as they are referred to in casting or foundry work . Yes what you see are all made from wood , the first in the process of making the same in metal is to make one in wood , a pattern , a male , then a female is constructed as a mould , to pour the molten metal into to create the finished product , a metal cog for a machine in industry .

This is the traditional way , now a days these items are Printed , built up with minuscule layers of wax in the CAD process . Computer Aided Design .. the creation process , changes in time .
