11. To attach the handle (N) to the front brace, first place a
washer (O) onto each of the two 32mm hex-head bolts
(P). Then insert the bolts through the holes in the front
panel (from the inside surface) and into the threaded
holes in the handle. Tighten the bolts with a crescent
wrench.
12. In the hole near the top of the left side panel (C) insert
the shortest (17mm) of the three black plastic bushings
(Q). In the hole near the top of the right side panel (C)
insert the middle-sized (25mm or 29mm) of the three
black plastic bushings (R). The latter bushing (R) is
longer than the width of the side panel by 1/4" or so –
that's by design.

13. To install the eyepiece rack (S), find the two pilot holes on
the left side panel, and screw one of the ½" wood screws
into each hole until the screw heads are about 1/8" from
the panel's surface. Then "keyhole" the eyepiece rack
onto the wood screws and tighten the screws to secure
the rack in place (Figure 7).
