How do you bend timber into a quarter circle?

[#1]

Bending timber beading into a quarter circle or other shapes can be achieved through the right technique. Timbers such as Tasmanian Oak are a suitable choice for this process.

Begin by preparing a container large enough to accommodate the length of the timber and place solid blocks inside to raise the timber midway in the container. Fill the container with boiling water up to just below the level of the blocks and place the timber on them so it is suspended above the water. Seal the container to trap the steam, creating a makeshift steam box that will soften the wood fibres.

Allow the timber to steam for approximately 10-15 minutes. This will make the wood more pliable and easier to bend. Using appropriate personal protective equipment (PPE) such as a long-sleeved shirt, pants, enclosed footwear, rubber gloves, and safety glasses, carefully remove the steamed timber from the container. Immediately place the timber onto a pre-constructed buck or form that matches the desired  shape. 

Gently encourage the timber to take on this shape, securing it in place on the form. Allow the timber to dry completely while fixed in this position. You may need to repeat the steaming and bending process several times until the desired shape is achieved. - MitchellMc
