Step 11: Make a Base for the Coils
The most important thing is to try to get the coils to be as close to the magnets without collisions. If you can position the coils on the base so they sit just 1 mm below the spinning magnets (watch out for wobble) then you're in good shape. Also, try to make the base as stable as possible. At higher RPMs, the turbine can really start to rattle a bit, so keeping things together in those conditions is crucial.
