Whoa I've been missing a lot of comments here, glad you guys like my stuff!

@InterstellarKev , that's really a cool ship with careful details, and nice gravity ring as well! Mine is more complicated because I want to integrate the contra-rotating rings that cancel out angular momentum, instead of having to rely on SAS. But that's just my personal wish, in game it's actually fine to just turn on SAS and let magic reaction wheels do the job - just like @Cereal Killer says.

I get (near) zero torque by experimenting. Simply cheat the whole thing into space, deactivate SAS, start rotating the main ring, and adjust the rotation speed of the counterbalancing rings until there's no rotation to be observed. Final values for this craft: main ring vs counterbalancing rings = 10 vs 295.

@JimmyBlether, you don't really need to. Reaction wheels are so strong in this game that the command pod alone can almost deal with the torque generated by the centrifuge. The counter-rotating wheels are really cool and this design looks great, but it's basically just for aesthetics.

My own design simply uses two of the larger reaction wheels either end of the centrifuge - then let SAS do its thing. Note: SAS isn't actually that good at dealing with torque over time, its much more efficient to use MJ aircraft autopilot and set roll-hold to 0 degrees :)

My Centrifuge isn't a complete circle either unfortunately - but that's because I build the entire thing in orbit using modules that fit in "realistic" fairing sizes. I suppose you could build a complete ring like this if you used the robotic joints (send up straight then form a circle with hinges) - but my computer struggles with part counts beyond 30 lol.

Still, this is a super nice design!

How did you ensure there was net zero torque?

There's a easier method Juggernoob. I recommend trying my method used in my design https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2245297985 using 1 (EP-37 engine plate) as the base then attach 1, (T-37 Structural Tube) using the Medium Variant. Place 1 (EM-64 HEAVY ROTOR) and attach to the EP-37 (engine plate) from inside, towards the back. then position another (EP-37 engine plate) to encase it all together in front of the (T-37 Structural Tube) This will make your mono gravity ring. From there build your ring. 4 part setup before the ring. Download my file and take it apart you can see i designed it to be separated easy for enhancing the build and easy application. Let me know what you think?

That's also tricky, I use symmetry + offset to form the ring, then remove 3 structural tubes from symmetry, and finally build the 3 "arms" separately.
