While on vacation at my cabin I was practicing some survival skills. I made a Firebow (Bow & Drill), figure 4 deadfall trap, and a simple shelter. I took some pictures and thought I would share them here for anyone interested in learning about them.
Some of the pictures did not come out very good so this pictorial may be lacking, feel free to ask any questions if you find this interesting and need more info.

There are five parts needed to make a firebow:
1) A stick for the bow
2) A string for the bow
3) A stick for the drill
4) A bearing block to hold the drill
5) A baseboard
There are other ways of doing this and some woods work better than others. By trying different types you will find what works best. Also you may find that a longer/shorter bow or drill may work better for you
Here is the way I do it.
1) Making the Bow.
I have used both dead and live limbs, either will work. If you use live limbs they will keep an arch shape as they dry if left strung and you will need to tighten the string over time.
When picking out a stick for a bow I look for one with a slight arch shape to it.
If I use a live limb I strip the bark, You do not need to if you don't want to.
If you find one with a "fork" in one end leave the fork on. This will give you a place to tie the string on that side. If there is no Y's (or "forks") I make a notch to hold the string. To make the notch I use the saw on my Swiss Army Knive (SAK) and saw straight into the stick. Next I use a blade and carve in toward the cut on an angle down to the bottom of the cut.
These pictures are from two different bows I made.
Here is another example.
After I make my notches I attach the string. I use Para Cord (550 cord) but anything could be used. A braided string or cord is better because it grips the drill better but I will show you a way to get a better "grip" on the drill later.
I tie a loop on one end and slip it into the notch. Sometimes I make a loop on the other end too, or else I just tie it on. You want the string tight but not real tight.
3) The Drill
You want to use a dry dead stick for the drill. You will sharpen each end to a rounded point. I use my knife and put four flat spots in the middle of the drill where the string "rides" so the string grips the drill better.
4) The bearing block
A bearing block is something you hold in your hand to allow the drill to spin freely. It can be anything, a shot glass, a stone with a hole or depression, ect. A 'Y' from an antler makes a good bearing block.
I did not get a pic of the bearing block I used. I used a shot glass. I wrapped it with duct tape incase it broke in my hand.
5) The Baseboard
The baseboard needs to be a fairly flat dry dead piece of wood.
I used an old piece of floor board that was laying in the firewood pile.
I use the awl on my SAK to bore a small hole close to the edge, then I use my blade to make the hole a little bigger.
Once I have a hole I put the drill in and spin it a little bit.
Once I have the hole burnished and the drill is "seated" and spinning nice I use the saw on my SAK and cut a small V shaped notch in from the edge.
Once all that is done you are ready to gather stuff to make a tinder bundle (A tinder bundle is a birds nest of tinder).
You put the notch in your base board over top of the tinder bundle and spin the drill. The friction from the drill spinning in the baseboard makes a fine brown powder that creates an ember that will light the tinder.
I did not make a fire this time just all the parts to the bow & drill but you may be able to see the smoke comeing from the drill.
Thanks for reading, I hope you like it.
