I selected a nice straight log of birch for this project that was free from knots and cleaned up the bark to keep the work from becoming dirty. I then selected a nice sized bit, the one shown is an unusual type as the blade sweeps back on itself.
This has a little scratch pin on it which marks the wood. I then used this mark to make a grove using a Frosts carving knife, and the Ben Orford crook knife which is a knife with a bent blade that is wonderful for shaping the insides of bowls.
The next job was to select a section of sycamore and split it down with an axe and wooden mallet until I had created a thin board. I then marked it with the shape of the inside and outside of the timber.
It was then a case of carefully cutting the board down until it resembled a thin oyster shape thinner on the edge so it would fit into the grove I had made. It was then a case of gently tapping the base into the end of the Birch tube until it slotted into the grove.
