Building a better Guinea and Feather

Step 14 Dowel extensions, handles, bolts

The dowel pin stops in the middle of the 2" support tubes. The dowel pin extensions and the 2" square dowel pin clamping blocks extend the dowel pin outside the support tubes and allow a long handle to be attached. The dowel pin extensions extend about 0.01" past the face of the clamping blocks. When the handles are screwed to the clamping block, the friction is enough to turn the whole apparatus.

Instead of flipping the apparatus upside down by hand, possibly breaking the brittle acrylic, people turn the handles quickly to rotate the apparatus.

The threaded hole on the handle lines up with the through hole in the sides of the support tubes. The locking bolt holds the whole apparatus in the upright and locked position during storage and transport.
