Cast Brass Machinist Hammer pattern and core box

thingiverse

These two parts can be printed in PLA and used as patterns to cast a brass or copper machinist hammer. The parts need to be mirrored to give four parts in total. The two halves of the core box are used to make a core from sand and sodium silicate or sand and epoxy resin. The hammer head halves fit together to make a split pattern for the sand mould. The core fits into the mould to create a void for the hammer handle. You will need to get a hammer handle to suit. I found mine here https://www.ebay.com.au/itm/261777725092
