62. Use 5 min epoxy to attach a hardwood block to each hole loca-
tion inside the fuselage. These will act as the screw backup when
you attach the cowl. The reason you do this now is because after the
firewall box is in place, you wont have access to this area - so make
sure they are glued in place well!
63. When the epoxy has cured but it still a little rubbery, remove the
tape from the outside of the holes and use a 5/64" bit to drill each hole
through the block.
64. Re-fit the engine box in the fuselage and attach the cowl with the
provided #2 x 3/8" button head screws and plastic washers.
65. Attach the spinner backplate and prop to the engine and slide
the engine in place so it is centered on the cowl opening and 1/8"
from the front of the cowl.
66. Use medium CA to tack the back of the engine box in place.
67. Remove the spinner, prop and cowl and use the hardwood tri-
stock and 5 min epoxy to secure the firewall in place. Place the tri-
stock as shown. Note: you can also sand the front of the firewall
where the tri-stock fits for better adhesion of the epoxy.
If you installed the cowl correctly, the firewall will automatically be
aligned with the fuselage very close to the proper incidence. If you
prefer, you can double check by using a square and make small
adjustments as necessary.
