Fork Mount Components - Top-Bottom Flanges and RA Axis Shaft

Top and Bottom Flanges - Right Ascension Axis Shaft (Click for enlarged view)
Here we have the right ascension axis plus the top and bottom flanges that will be incorporated into the Fork Mount Head. The shaft (which is made from T-6061 aluminum) will slide into the large 2 1/4" I.D. Hanger Bearings of the lower Right Ascension Axis Support Housing. One of the above pictured flanges will be concealed inside of the RA Axis Box on the top section, while the other will be externally mounted to the bottom section of the RA Axis Box. The flanges are comprised of two components, one is the flange itself, and the other is one half of a 3 1/2" pipe  threaded on both ends and cut in half.
