Between the window and the side doors is a narrow strip of wall available to house a small console. It is the future location of the battery monitor and a reading light.
With a narrow piece of wood, the length of the console, placed against the inside wall, the curve of the wall is transferred to the wood. Back in the workshop the form is cut and adjusted to get a perfect fit.
In the meantime, some wood is planed to a 1/2” thickness and the form is temporarily attached to it. With a straight-edge bit, the form is exactly copied to the wood. This and another copy are the two sides of the console.
