1-9. Tie a loop in one end of one of the 23" (580 mm)

shock cords, securing the tail with masking tape. Tie the

opposite end of the shock cord using a sliding knot, slide

over the front (not hardened) end of the motor mount tube

and tighten.

1-10. Apply wood glue to the inside hole of the forward

centering ring (ring C) on the latch assembly, pass the

shock cord through the center hole and align it with the

notch while pressing the motor mount tube into place until

it bottoms out. Check that it is visually square to the latch

assembly. If this part isn't built square, the removable

mount will be difficult to install in the rocket. Once it is

straight, pull on the shock cord to tighten the loop against

the alignment frames.

1-11. Apply wood glue to the joint between the forward

centering ring and the motor mount tube then form a fillet

by shaping it with the tip of a finger. Also apply a fillet to

the shock cord all around the motor mount tube.

1-12. Make a ring of wood glue at the marked point 5/8"

(16mm) from the end of the tube. Slide the aft center-

ing ring assembly (ring D) with the base of the L facing

inward into place at the mark, aligning the hole with the

line drawn on the motor mount tube. Once the ring is in

place, apply a fillet to both sides of the ring. Let the glue

dry entirely.

1-13. Insert the all-thread rod into the mount through the

hole in the aft centering ring. The rod should extend

3/4" (18mm) beyond the end of the motor tube. Using a

thickened epoxy (such as Fix-It Epoxy) glue the rod into

place. Let the epoxy harden entirely before attempting

to install the mount in a rocket. Adjust the fit of the latch

as described below on page 10 ("Adjusting Mounts for

Correct Fit")

2-1. (Optional) Harden 1/4" (6 mm) of the end of the

motor mount tubes by saturating the inside with thin CyA

glue. This makes them less prone to damage. These will

be the aft end of the tubes.

2-2. Place one of the tubes against a door frame or sec-

tion of aluminum angle and mark the tube lengthwise.

Place marks at 1/8" (3 mm) from the forward end and 5/8"

(16 mm) from the aft (hardened) end. Mark the other two

tubes similarly.
