we have a close-up shot of the lower external right ascension axis
flange with the shaft installed. As seen in the photo, their are two holes
drilled into the flange, whereas one has been reamed out to allow a
1/4x20 thread machine bolt to pass through it to reach the drilled and tapped
hole in the wall of the right ascension axis. The other hole was drilled
through the side of the flange and tapped to allow a 1/4x20 thread hex
head lock screw, or machine bolt to push against the shaft. The same
procedures were used on the top internally mounted flange. To center the
shaft inside the flanges, 1/16" inch
shims were utilized. Also note the
numerous wood screws used to assemble this bad boy. It is no doubt tight
rock solid. |
