Hot Dip Application ---
Heat between 2 and 8 bars of SheathCoat ™
in a container that will allow the waxes to reach a temperature between 225-250
degrees f. and allow complete immersion
of the sheath. Bend a sturdy coat hanger so that it will fit snugly
into the sheath. It must be able to hold the weight of the sheath and
the waxes that temporarily fill the sheath during dipping. Dip the sheath
slowly into the hot liquid. Dip approximately 10-20 seconds. If you begin
to see yellow bubbles, pour out excess liquid from the sheath and remove
immediately. Be careful, the liquid is hot and can burn. Insert the knife
..(pre-wrapped in tin foil to protect the knife).. into your sheath and
use a smooth blunt instrument to press the hot leather to the shape of the
knife in the handle area. This assumes you are preparing a pouch sheath.
Otherwise, this step is not necessary. Place the sheath in the icebox and
allow it to cool completely. BE CAREFUL...Hot waxes can and will
burn if they come in contact with eyes or skin. Remove the
sheath and knife from the icebox when the sheath has completely
cooled. The knife may be removed at this point and the sheath will
retain the handle shape so that you will always have a glove fit for your
trusted blade.
A word about soak
temperature and soak time. I find
that the range of 225 to 250 degrees f. and soak time of 10 to 20
seconds are the optimal ranges of use. A temperature of 225
degrees f. allows a soak time of 20 sec. and 250 degrees f. allows
soak time of 10 sec. These are the rules of thumb that I
use. Over the years, I have tried temperatures up to
300 degrees f. However, temperatures in this range tend
to cook the leather even with short soak time. You know you
are cooking the leather when you see yellow bubbles coming from the
sheath. Temperatures much below 200 degrees f. and the waxes
and oils do not soak well into the leather. You know this is
the case when you remove the sheath from the hot dip and the excess
waxes and oils just cake up on the surface and do not soak into the
leather. You have two choices at this point. The first
is to raise the temperature of your dip solution and then resoak the
sheath. The second is to put the sheath in the microwave for
10 seconds on high. This will allow the sheath to soak up as
much of the excess as it needs.
WARNING... do not use the microwave method if the
sheath has any metal as part of the construction (like rivets or
snaps). The metal will damage the microwave oven. Snaps and rivets
must be added after the SheathCoat TM treatment. If you use
the suggested ranges of temperature and soak time, you achieve the
best results.
NOTE: It is a good idea to prepare small pieces of leather ( 1" by
2" strips with hole for dipping rod) to test different temperature and time
combinations until you are satisfied with the combination that works for
you.
Single sheath Wrap Application ---
Wrap the sheath completely and tightly with the gauze
wrap impregnated with SheathCoat ™. Place in the microwave oven for 30
seconds. Generally this will be enough time to complete the
operation. After the wrap cools enough
to handle, unwrap the sheath and insert the knife and follow the
instructions in the hot dip method above for forming the sheath to the
knife handle. ...WARNING... do not use
this method if the sheath has any metal as part of the construction (like
rivets or snaps). The metal will damage the microwave ovenSnaps and rivets must be added after the Sheath
Coat ™ treatment.
Tips and
Tricks ---
- Completely prepare the sheath prior to dip or
wrap. This includes sewing and edge preparation.
- Tooling leather in the 10oz to 12oz range
responds best to molding and retaining handle shape and accepting the
brown patina.
- The results from dipping or wrapping a sheath
that already has a surface finish are inconclusive as to final color
and wax and oil penetration.
- The completed sheath may be buffed to a soft
rich glow with soft rag or lambs wool buff.
- The completed sheath responds well to edge
polishing with deer antler or other hard smooth object. We prefer the
deer antler.
- A sheath done with the hot dip process (and still hot) may be
inserted into the microwave oven for 10 seconds on high. This should
only be done once and insures that SheathCoat ™ has reached every
pore of the leather.
