Carving hollows in wood is a more time consuming process than planing it flat.
However, it gives you another way to improve your skill in wielding an adze.
Hand adze or foot adze?
The size of adze you need depends on the size of the piece of wood you’ll be working on.
If you’re working on a long pole to make a gutter or a log to make a dug out canoe, you may need a foot adze.
If you’re working on a smaller piece of wood to make a bowl then you’ll need a hand adze.
If you’re working on a medium-sized piece, such as a chair seat, you could use either size of adze. Go for whichever one you feel most comfortable with.
Example: carving a bowl
For this type of carving, your adze will need a lipped blade.
Step 1 – Mark out guidelines
Mark the area that you want to hollow out in pencil if you need a guide.
Step 2 – Begin carving
You’re now ready to start carving – be patient and keep things relatively shallow to begin with.
Step 3 – Mark sides
Once you are satisfied that you’ve hollowed out enough wood, draw lines on the back of your bowl to show where the area you have just hollowed starts and stops. This will help you to accurately shape the outside of the bowl.
Step 4 – Shape sides
You can now use your adze to shape the outsides of the bowl.
Carving and hollowing other things
The same process for hollowing out bowls can be used for gutters, seats and canoes, and sculpting with wood.
Totem pole carvers have a history of using adzes to leave marks all over carved poles, which gives the totem an authentic finish .
Adzes and burning out canoes
The hollowing process for gutters and canoes can be sped up by burning them out using hot coals.
Water is used to wet the sides of the wood so that it doesn’t burn away as quickly.
The burning process builds up a layer of charcoal, which is both waterproof and insect repellant.
In this case, the adze is not only used to start the hollowing process but also as a scoop to remove ash from the inside of the hollow.
