The Ringworld/Sphereworld plan:
1. Build Space yard base I over star.
2. Space yard base builds Space Yard Base II.
3. Space Yard base I starts on starbase with generator comp.
4. Space Yard base II builds more space yard bases, and new space yard bases build new space yard bases, until you have the number of space yard bases equal to the number of plate and cables needed.
5. All space yard bases except Space Yard base I start building starbases with cable or plating components.
If your time it correctly the generator comp is built at the same time as the cable and plating bases without having to put any on hold. At the most you can put the Space Yard I on hold for a few turns if the others need to catch up or on emergency if it falls behind.
Once the ringworld is done you can scrap the space yards, or put them to work building defenses on teh planet.
This is how Drake taught us all to do it during the Twingalaxies tourney years ago.
