I thought a fire hydrant might be a fun object to model.
The first part of this kind of modeling is research. Although I've seen a million
hydrants in my lifetime, the ones from around Boston are the ones I remember best.
It's interesting how many variations there are, and how many pictures you can find.
Specs: This particular hydrant type is made from cast iron, and the threads are bronze.
It is a dry barrel pressurized hydrant where the valve is deep below ground
and there's no water in the body to prevent freezing in the winter.
Three threaded connectors, one 4" and two 2.5" that are 5" and 3 1/16"
outside diameter respectively. The 4" is 4 threads per inch, and the 2.5 is 8 tpi.
Some early cities had wooden water pipes carved out of logs buried next to streets
and when a fire broke out the would have to dig one up and bust it open with an axe
to get at the water. Later they pre-drilled holes in the logs and corked them up so
they wouldn't have to repair them every time there was a fire. Thus leading to the
term some still use for a hydrant today the "Fire Plug".
