Crimson Core Steam Engine Mk1

Two perpetual Level 4 Steam Engines that produce over 120,000 SU together.
They are powered by lava extracted from the Crimson Tree by the Sappers in Create:Rubberworks. When the reservoir fills with lava (40 buckets), the Threshold Switch shuts down the Sappers to conserve SU, turning them back on when there are 8 buckets remaining.
It has a 64rpm rotational power output on the front, and two 96rpm outputs on the sides.

How to turn it on:

I advise against rotating the Schematic. First, put water in the reservoirs following the order of progression of the pickaxes in the reference images (wood, stone, and iron). Then remove and replace all the Sappers. Then just put a bucket in the depot and some pieces of coal in the Portable Engine. If you want to speed up the process, just put some buckets of lava in the reservoir or directly in the Blaze Burners.
