Cast a water pump impeller with phenolic resin sand

[Xijian Su]

I am going to make a water pump for my engine.
The pattern was made with Acrylic and wood.

Since the part is so small, I decided to use the phenolic resin to bond the sand.

Sand core making.

Ready for casting.

Phenolic resin sand preparing
2130 resin & hardener.
Fine sand.
I mixed the sand with the mixture of resin and hardener (10:0.8). 30-40g of the resin to 1000g sand.

The used sand can not be reused.
