In this video you'll learn how to make a halving joint.
The halving joint will allow to fit two round logs of wood together securely. They can then be fastened in place with a lashing or dowel - learn these techniques in the following videos in this series!

In this video, we're going to learn how to make a halving joint
This technique allows you to join together two logs. You will then be able to make structures such as a raised tent-cot, a bench, and many other wooden constructions.
Caution, this job requires
to make a halving joint, you'll also need
a bow saw
a wood chisel
you'll also need
two wooden logs
Making a halving joint can be done in 4 steps which will outline for you
Step 1: Mark your reference points
Place one of your logs on top of the other at the angle you wish to join them at
Use your saw to mark the reference points for where the upper log will sit on the lower log
Put the log without markings to one side
Step 2: Sawing the log
Saw one third, or upto half way, into the log on your reference points
Don't saw too deep into the log so as not to weaken it
Make sure the cut is straight, sawing parallel to the floor and perpendicular to the log's surface
Step 3: Hollow out the wood
Position the log so that the references points where you have sawed are facing upwards
Place your foot on the log to secure it in place
Take the chisel, making sure that the bevelled edge is facing towards you
To hollow out the wood, dig out small notches with the chisel
Then hit the chisel a little harder with the help of your mallet, pushing it back and forth to carve out bigger notches
Continue hollowing the marked area until the entire area is flat
Once the first log has been hollowed out, place it onto the second log
And repeat the steps on this log, mark references, saw, then hollow out.
You can also turn the log onto its side to hollow it out vertically with the chisel
You will end up with the two hollowed out areas which can fit together
Step 4: Assembly
Use the mallet to hit the two logs so that they fit together well
If they do not, this means that your measurements were incorrect
Go back and re-measure your reference points and saw and hollow out the part which is preventing them from joining properly
To strengthen the joint, you could even include a dowel

You could alternatively tie a square lashing over the halving joint
