Plastic both the window and the window frame with the adhesive. Carefully position the
window in the opening and tape in place until the adhesive cures. Squeeze out any excess
adhesive, and wipe off excess and smooth a bead around the edge of the joint. before
adhesive cure .. Removing the second layer of duct tape will help make cleaning around
the bonding area easier.
ASSEMBLY door lock
The 4 place door latch, while much like the two place latch incorporates changes
to improve reliability and rigidity. The main difference between the two latch
configurations is that the rigid tubes replace the cable and spring system of place 2. This
results in a much stiffer system when the door is closed, and a direct indication is provided
to ensure that the lock has occurred.
A rectangular aluminum tube section is provided for the fabrication of this handle.
The pivot points for the pressure tubes are in line with the basic pivot axis, at about 1 and
1/4 of an inch on each side of the pivot (one inch. The displacement shown in previous
drawings is quite minimalist and one inch of a room will be compensated to provide more
travel and more reliable overlay on the lock). Drill and countersink face one on each side
of this center pivot for a #10 flat head, and drill and tap the other face for the #10 X 32
UNF thread.
The operating sticks are made of 3/8 OD aluminum tube with approx. 0.040 thk
wall. The handle ends of the tubes are drilled with a day of clearance. (about 0.190). Hole,
and a smaller amount of bending will be required for satisfactory lock function.
The locking ends of the tube should be tapped to a 5-16 UNF thread, and the two
locking bolts can actually be the screws with a
