Drilling 3 x 115mm eucalyptus posts in one go with the 450mm rebar drill bit.
We need this drill bit to form the holes that we are going to use to thread another piece of rebar through to lock the posts together.
Basically the drill bit is made from a piece of rebar heated in the fire, hammered and twisted whilst hot.
Then sharpened on the angle grinder into a drilling machine
There is some use and ‘mild’ abuse along the way of the drilling process (you can see more of that in the video)
Checking his progress though the king post and into the floor support beam
