Rudders...E-Glass, S-Glass, Kevlar, Carbon Fibre
Rudders: Spade rudders can be
fabricated using stainless, E-glass, S-Glass, Kevlar, Carbon Fiber
rudder posts supplied from another manufacture or built right
here at Gable Enterprises.
Transom hung rudders are usually, but not always, built from unidirectional
S-glass and Carbon. The cutout that you see on the front side
of the rudder, where it meets the stern, tends to put much higher
stresses right at waterline. Transom hung rudders commonly break
at this point. Using unidirectional ( 1 direction ) fiberglass allows
us to customize the load path which reduces weight/thickness of
the rudder. Since spade rudders are usually more balanced with loads
generating towards the shaft, we wrap the shaft and the blade of
the rudder with Biaxial ( 2 directional ) fiberglass. Custom fairing
using designed templates is then completed and finished out with
an Interlux V127/128 or Awlgrip 545 white Epoxy primer wetsanded
to 600 grit. In the case of wet sailed boats we generally recommend
your favorite go-fast bottom
paint wetsanded to 600 grit as a finish coat.
Rudder Posts...E-Glass, S-Glass, Kevlar, Carbon Fibre -
Gable Enterprises has built
Carbon, Carbon/Kevlar, Stainless, E-Glass, and S-Glass rudder posts.
We can build/Estimate from your plans or Design and build in house,
whatever your need.
Bagging - Gable Enterprises currently
has 3 vacuum bagging pumps that are currently used for various purposes.
Their primary purpose is for the vacuum bagging of laminates. We
use them for repairs of one design sailboats to keep the weight
gain to an absolute minimum. Ask your current repair facility if
they use vacuum bag techniques for their repairs. Vacuum bagging
gives you a lighter laminate in the repair because it removes the
extra resin with use of a bleeder. It also gives you better bonding
as it actually compacts the laminate in a tighter atmosphere of
glass which helps complete air removal that is common in most hand
lay-ups or repairs.
- Gable Enterprises has been recently completing repairs with Resin Infusion. This process allows us to
introduce the resin into a preformed vacuum bag at a precise locations and introduction times. This produces a controlled repair
that is usually advantagious for those large frp repairs in those hard to get to areas like the bilge turn or keel grid areas.
Assist - Vacuum pumps
are also useful in the removal of water from cored boats. A common
occurrence with cored hull/deck damage is water traveling into the
core after a collision as your on the way back to the dock, or just
finishing the race. In this case we generally drill suction holes
approximately every 6-8" in a grid pattern, remove the intruding
water, then affect repairs to the area. Ask your current repair
facility if they do this with their repairs. In a recent case, a
one design race boat came to us for repairs. We noticed that there
were two prior repairs on the starboard side of the boat. After
putting a Sovereign moisture meter on these repairs to measure moisture
content, the meter immediately maxed out. This meant that there
was total saturation under the repair, so the repair facility had
completed all their repairs while the core underneath was soaking
wet. Don't settle for second rate work while paying a premium. Come
to Gable Enterprises to get your race boat repairs completed the
right way... Don't
settle for less!
Fabricated Parts - This
is a fun one. Gable Enterprises
has built some creative projects ranging from
skateboards with vacuum bagged carbon and Kevlar, to spoilers and
air flow ducting on custom Porsche' play cars. Testing has also
been done on Unidirectional custom Carbon chain plates....we haven't
quite worked this one out yet, but never less it created the opportunity
for further development. Click on the image of the Porsche to see
