This mod adds three windmills:

• Windmill - Makes concrete and flour
• Sawmill - Makes planks
• Masonry Mill - Makes bricks and slabs

Mitty and I did some testing. We tried various containers and configurations. Crate racks won't work. BSB's won't work. Other containers won't work.

1. Expand a BCU so it has a main container.
2. Expand at least two rafts. Put them in the BCU main container. You'll want 61+ cast.
3. Put the BCU in the windmill.
4. To mass craft concrete add stone shard to one raft and clay to the other, 100 each. Creates 100 concrete at a time.

I assume the other windmills work the same way.

More as I know it.
