This is the first expansion pack for Age of Steam:  Workshop Expansion

It adds the following blocks:

• Mechanical Sieve to process sand, gravel, dust and find valuable resources
• Manual Spinning Wheel to make strings from wool
• Millstone (=crusher) to process wheat or crush ores
• Woodmill to cut wood into planks
• (maybe in future): Mixer to mix a liquid with solids, for example to create slime

all machines will have a config where you can add / remove recipes as you like.
