Ply blocks were inserted outside the
center hinge parts and after drilling the locations small screws were
installed to lock the removable parts in place. The screws are
installed on the top and the bottom.
The fin front support was drilled for a
sheet metal screw.
With the fin and elevator assembled to the
fuselage, a hole was drilled through all associated parts and a length of
6-32 all-thread was installed in the fin. The upper nut is glued to
the all thread and the fin.

the filler blocks of balsa that center the fin support between the upper
longerons
The motor mount will be removable on this
Boxcar 108. The mount parts were assembled to the firewall using a
rubber band and clamps to hold it together while the 30 minute epoxy
cured. Then it was removed from the firewall and 1/4
inch basswood milled into corner stock was glued into the
vertical corners. Material mast be removed from the bottom
plate of the mount to clear the landing gear.
