Making you own glue is a wonderful experience but do not expect to find a
"super glue here". They worked with what they had, which includes (plus a
modern cheat):
While the traditional hide glues and sinew/hide lashings had a weakness to
moisture, they found a cure in pitch. While it took me several years of
trial and error to discover their secrets (no Internet back then) I offer
you the secrets in as long as it takes you to read. Have fun!
Hide Glue
Making your own hide glue is a waste of time as it takes many hours, is a
messy/stinky process and you can buy pre-made stuff now for way cheaper
than you can make it for. Still stubborn enough to try it, well read on.
It first
starts with saving your hide and sinew scraps - no leather will not work.
To save time,
cut them into small pieces and place into a pot. When you have enough, add
water and make a soup. Place over a burner and bring it just below boiling
and stir occasionally. You may need to add more water as it burns off as
steam - you do not want it to burn.
You can tell
when the hide is breaking down as it will foam into a goo. Once it does
completely pour it through a strainer or collect it through other methods.
It is ready
to use. What you do not use will dry and can be used later by reheating.
It is not
water soluble and will wreck with high humidity, water or blood. Indians
solved this problem by further soaking the lashings/glue in bees wax or
pitch (sap).
Pine Pitch
Measurements (Does not have to
be exact but close)
Pine Pitch is
not a glue and will not work as such. It is simply a filler used to fill
excess spaces made when hafting items. It also works as a sealer for
sinew, hide and hide glue to prevent them from giving loose when wet.
With that
said, it is an important part in traditional haftings and is a pleasure to
work with in every part.
The most
enjoyable part is collecting the sap (pitch). You can get the sap from
Spruce or Pine trees (only trees that I have tried) which both work
equally. You want to get the almost white, fresh, sap from open wounds on
the tree. I use to feel guilty for slicing a tree and coming back later so
I went to campgrounds where it seems many people do not share my concern
and have buried their hatchet in many trees.
If you do not
have a campground in your area but trees that you can cut, put a couple of
diagonal cuts in a tree. Sap will run similar to water so where you think
that it will run, place a small can/cup under the area to catch the sap
as it comes out.
Otherwise,
just use a dull knife to scrape the sap into a bucket of some sort. Be as
careful as you can not to include bark and other items that will just add
time later. Also the old amber and dried sap will not work as good as it
is brittle.
Once you have
half a coffee can or 1/4'' of an ice cream pale that will be enough for a
while, but it is always better to error on the side of more.
Now go
through your collection and pick any non-sap items out.
Put a small
amount in a tuna fish can (or pot) and heat slowly - do not bring to a
boil - and stir. It will take a while to melt. When it is liquid pour
through a metal strainer into another pot. This will separate any bark or
other items. Each time measure the amount of pitch going in.
Once done
with that, take some animal fat such as bacon grease, animal fat or Crisco
(available at any food store). Measure it to 1/4 (fat) to 4 (pitch) and add
it to the pot with the pitch. Too much will ruin it so it is better to start small and
add as you need it. Some sites say to add one part and others say to add
none? I have found 0 can be brittle and 1 part is wax that does not
work. There are many other factors, I am sure, but less is better.
Now for the
boring process. Take charcoal (smaller the better) and grind it down to
dust. I use a flat piece of hard wood to place the charcoal on and a flat
rock. It is very important to grind it down to dust as any chunks will be
a weak spot in the glue. I then dump the dust onto a piece of paper and
funnel it into the measuring can.
The dust will
mess with your lungs so a mask is recommended. A fan will just blow it
everywhere.
When you have
1 part of ash to 4 parts of pitch, add this to the pot.
Now heat the
pot, but not to a boil, and stir constantly until it is a well mixed soup.
If it does boil, don't worry too much as I have boiled mine for 40 minutes
to get rid of excess fat with little problems but it does seem to work slightly better without
being brought to that temperature.
Now the
Indians use to then pour it into several holes in the sand to let dry. I
do something differently that I suspect that they may have done as well.
Take some broken twigs/sticks (size don't matter but I use 5/16'') and dip
into the pot and remove. Let it dry to test. If it:
-
dries hard but not brittle: you
have the perfect mix.
-
dries hard and brittle: you need
more fat. Add more fat, stir and try again.
-
dries but is waxy: you have too
much fat. Add more ash and pitch and try again or boil for 30 minutes and
try again.
Once
satisfied dip more sticks repeatedly. Each time the removed stick will
harden and can be dipped in repeatedly until it has a thick round ball of
pine pitch on it. This part though does require the pot to be in cooling
mode (turned off). If it is too hot it will just melt the stuff on the
stick and you will be going nowhere fast.
Once you are
satisfied with the pine pitch ball the stick can be placed aside and left
to dry. Repeat that process until all of the pine pitch is gone.
Now you have
pine pitch sticks that can be stored for years and used as you need them.
How to use them
When I use
them on areas that have big holes I need filled like tomahawks I use a
lighter to light the pitch stick on fire - it will catch fire very easily
which is why the Indians also made pitch torches. Once the pitch stick is
on fire I hold it down to let the hot pitch drip into the areas needed to
be filled.
For knifes,
another method is to take a lighter and heat the pitch for about 20
seconds. Then lick your finger to prevent them from burning and mould it onto
the area. Then use the lighter to finish it. Some practice will be
required in this area.
It is a
science though depending upon your area and humidity. For example, too
much char can make it brittle while not enough can make it remain sticky.
Just like fat, too much can make it remain like fresh chewed bubble gum.
If this
happens to you, as it has to me many times, then you can just re-heat and
add more pitch and charcoal testing constantly till you get it right.
Warning:
Pitch will catch fire very quickly and any drips on skin will burn
instantly.
Knox Gelatine
This is the method most "Traditionalist" use now-a-days as it is the
cheapest, quickest and most authentic method.
Take one package (1 tbsp) of Knox gelatine, which is available at any
supermarket. It depends on the amount of glue that you need, but lets say
a lot. Add the package of 15 ml (or 1 tbsp) to 50 ml. of hot water in a
coffee cup and stir. Microwave for 1 minute or until it starts to bubble
over. When it does, take it out and stir quickly.
You know have 5+ minutes to apply the glue before it starts to gel.
Otherwise keep it on a burner at medium heat. You will have to scrape off
the top dried part though. It is
that simple.
You can do two things here. Either use a paint brush to dip into the glue
and wipe it onto the area to be hafted and lashings afterwards or dip the
hide/sinew into the glue and wring out before lashing it to the area. If
you do the latter method just make sure that the glue is not too hot or it
will cook the sinew.
