With
the I-Beams installed inside of the RA Axis Box, we are now ready
to install its top section. But, before this can be done, the right
ascension axis must be attached to the flange of the top section. To accomplish this, holes
will be drilled into the side of both the flange and one through the right ascension
axis shaft. One of the holes will be tapped in the flange to accept
one 1/4"-20 thread machine bolt, which will push against the shaft, while the
other hole will be reamed larger in the flange to accommodate the second
1/4"-20 thread machine bolt to pass through to the threaded hole in the shaft. A
1/16" inch shim will be
inserted between the Right Ascension Axis shaft and the inside wall of the flange to
center the shaft effectively.
