drawn on the plan. The 1/8" ply bottom should be installed with
the four towhook hole marks DOWN so you can tell where to drill
the towhook holes after the fuse is assembled. NOTICE: two
slots for former F6 are formed when the two pieces come
together. Make sure the bottoms are aligned with the plan and
both pieces are pushed firmly against the work surface to even up
the bottoms. If the joint is a nice tight fit, apply thin CA to the
joint. If the joint is a little loose, take the bottoms apart, apply
med. or thick CA and reassemble them.
D 2. Trial fit all of the 1/8" Die-Cut Ply Formers (SPT1F08
& SPT1F17) except F1 in the respective notches in the fuse
bottom and trim them if needed to make them fit properly. The
formers may be a tight fit in the slots but push them all the way
down against the fuse bottom, this is to keep them lined up so the
fuse will end up straight. Use a drop of med. or thick CA to "tack"
glue the formers in place. The notches in the fuse sides will align
the formers correctly.
BB2. Sand the plate if needed to make it fit. Apply med. or thick
CA to the bottom of the plate and press it in place. Do not allow
the fuse sides to become glued to the bottom yet!
D 5. Spread the fuse sides out and apply med. or thick CA to
formers F5, F6, BB1, BB2 and the bottom edge of the fuse sides
between them and reassemble everything. Check to make sure
the sides are pressed firmly against the formers and the bottom is
fully seated against the fuse sides, and allow the glue to cure. Use
rubber bands and/or masking tape to hold things while the glue
cures.
D 6. Pull the rear of the fuse sides together and make sure the
sides are pressed f i r m l y against former F7 and the bottom is fully
seated against the fuse sides. A couple of C2 clamps can be used
to hold the tail of the fuse together and rubber bands or masking
tape will help elsewhere. Apply CA along the back edge of the
rear fuse doubler, along the bottom sheeting joints and around
former F6. Take your time applying the CA and be sure to get the
bottom and the sides pressed together nicely. Med. or thick CA
can then be added to these joints to add strength.
D 3. Align the fuse sides with the fuse bottom and position the
formers so they will key into the fuse side notches. Remove the
assembly from the work surface and use rubber bands to hold it
all together.
D 4. Check the fit of the 1/16" x 2-1/8" x 3-7/32" Ply Tow-
hook Plate (SPRTW05) in its slot between formers BB1 and
D 7. Pull the front fuse sides together and trial f i t the 1/8" Die-
Cut Ply Former F1 (SPT1F08) in place with the punch mark
toward the rear of the fuse. Apply med. or thick CA to the bottom
of the fuse sides and the formers, install F1 and pull the fuse sides
together. A few rubber bands and tape can be used to help hold
the assembly while the glue cures.
