3rd attempt at pulley mold came out okish

These latches are great for holding the mold closed.
 
Drag done, 

Blowing out the sand from the holes for the locating pins.

Sifting sand on for a smoother first layer.

Ramming the sand, with a home cast sand rammer

First attempt

All went pair shaped when I tried to remove the patterns.

The simple shape was fine.

Changed to some other sand, not as fine, but higher green strength.

Not too bad

Core in place.

But the sand was too dry.

Mixed in a little more water and tried again.
