Entirely correct, well done
Reiterating my original notes were:
- Step 1 unlock cog w/catholic key 1
- Step 2 slot Buddhist Wheel on
- Step 3 fit cross into wheel
- Step 4 using ropes and giant crescent add weight to wheel, allowing cog to turn
- Step 5 use key 2 to open the door!
...right, now I have to come up with another puzzle
