The Groove-LOK is
the latest in fin
attachment technology.
It epoxies over a 38mm
motor tube and makes
attaching fins much more
efficient. Made of
high-strength extruded
aluminum, it holds the
fins in perfect
alignment. It's a fin
alignment guide built
into the rocket.
Let's face it, attaching
perfectly aligned fins
the old fashioned way is
a bear. You have to aim
and drip epoxy down into
an impossibly small
space while keeping the
fins straight and
aligned, making sure the
epoxy and cloth are
making contact, while
keeping the epoxy drips
out of the motortube.
off the airframe and
away from your shoes.
Fun, huh?
The Groove-LOK
adds incredible strength
to your fincan area,
with very little weight
gain. It interlocks all
fin canister components,
and transfers loads.
Much stronger than a
standard layup.
Using
diagram 1 below, compare
the dimensions of the
"A" "B" and "C" linear
measurements for picking
your fins. The shaded
area to the left of the
fin in the diagram is
the through-the-wall fin
tab.
Specify fin tab width,
or indicate airframe
size and motor tube, and
we'll determine the tab
dimensions. When
ordering online, use the
comments area on the
checkout page to specify
fin tab information.
TECH NOTE:
G-10 can be cut using a
jig saw with a
fine-tooth metal blade.
Sand edges smooth by
hand or, better yet,
with a bench disk sander
or similar tool.
Careful, G-10 is very
dense material and can
destroy cutting bits /
blades. G-10 can cut
you!
Always wear hand and
eye protection as well as a breathing respirator.
