CR especial base pole and mounting structure

Bryan has finished constructing the mounting pole, turbine housing and base plate for the attachment of the turbine blades which are similar to CR especial V2.0 beta (more to follow when he finishes constructing the half-sized blade assembly v2.0 beta is 3′ tall, v2.1 will be 5′ tall and v2.2 will be 10′ tall).

Below are some pictures of the finished turbine housing / baseplate assembly.  Incredibly the trend to building with PVC continues … only 1 part is not readily available in the Home Depot plumbing section.

The center shaft mount and connection to the turbine is simply 2 4″ toilet flanges mounted back to back.  The housing for the turbine is 4″ PVC, with a 2″-4″ converter for keeping rain/moisture out of the turbine housing.  Finally the base pole is 1″ steel pipe attached to a 1″ threaded flange, attached to another 4″ PVC toilet flange which attaches to the 4″ PVC turbine housing.

A little creativity and several trips to Home Depot is all it takes :-)
