Engineering is a chain: powders and parts you make early go into the gadgets you make later. This road follows that chain, so most parts you craft for points get used again a few steps on.
Mining is the natural partner: stone for the powders, bars for everything else.
Good to know
Mining is the natural partner. Make your own parts: bolts, tubes, blasting powder, casings and triggers.

Orange always gives a point, yellow usually does, green only now and then. The counts include spares for the yellow and green crafts.

Make 32 to go from 1 to 30. It is orange until 20 and yellow after that. Most yellow crafts still give a point; the count has a few spares for the ones that do not. You know the recipe from the start.
