Overview Tip spacers perform the
same function as sidewalls - to protect the core from damage caused by moisture and impact.
The tip and tail are more susceptible to damage because core is only 2-3mm thick
in these areas. The use of spacers is optional, but we highly recommend
them for durability reasons.
ABS plastic and P-Tex are the most common materials used for
tip and tail spacers. Other choice of materials include fiberglass,
carbon fiber, Kevlar and other composites or plastics.
Making ABS Tipspacers
Step 1: Outline Tipspacer After the wood core has been profiled and
sanded down, take the ski template and trace the outline of the ski's perimeter on
the core using one of your templates.
Next, outline the areas that will be tip (and tail) spacers. The spacer can
be any shape and should have the same thickness as your tip and tails (2-3mm).
Step 2: Cut Tipspacer Use a jig saw to cut away the tip spacer areas
from the core and cut out the corresponding
shapes from the ABS material. Attach the tip spacers to the
tips and tails using small amounts of super glue. The super glues prevents the spacers from
shifting during the layup process.
In the picture above, notice that there is extra tip spacer material. There should be
enough to generously overlap the ski's edges. The excess material is trimmed during the finishing
step. Note that P-Tex
or any other type of plastic spacers are made in the same manner as described.
Making Fiberglass Tip Spacers Fiberglass (or any other type of
composite) tip spacers are attached during the actual ski layup process.
Step 1: Cut out Tipspacers First, cut away the tip spacer
area from the profiled core as described for making ABS tipspacers.
Next, cut out several pieces of fiberglass material in the shape of the tip
spacer. There should be a minimum of two layers of fiberglass for one tip
Step 2: Layup Tipspacers When the core is placed in the
mold during layup, place the fiberglass cut-outs at the tips and tail area.
The fiberglass spacers are created after the epoxy cures.
