Here
is the bottom side of the top section of the RA Axis box. The flange
will be concealed as mentioned earlier to allow for slightly shorter
fork tines/ arms, and for esthetics. The flange is mounted to the 23"
inch by
7 1/4" inch plywood piece by means of 3/8" inch machine bolts, standard
washers, and lock washers. Please note, before the top is attached, the
T-6061 aluminum right ascension axis shaft tube (1/4' inch wall
thickness)
must be inserted and mounted to the flange in conjunction
with the 1/16" thick shims made from these
galvanized plates. One hole is drilled through the flange and the shaft. The hole
in the flange is then reamed to allow a 1/4x20 threaded machine bolt to pass
through it. The slightly smaller hole in the shaft is then tapped for
the 1/4x20 threaded machine bolt to screw into it. This will prevent the shaft
from slipping up and down through the flange. Approximately 30 degrees
from the first hole, another un-reamed hole will be drilled into the
flange, but not through the shaft. It was tapped for another 1/4x20
threaded machine bolt, or hex-head lock screw so as to screw through the flange
and push against the shaft to stabilize it.
