Having a nice afternoon in the workshop today
With the edges cleaned up, the hatch opening can be drawn easily, using the Marking Gauge with a soft pencil….Viz

The hole was cut out using the new Dremel Trio with special cutting out drill, that thinks it`s a saw!…..Something I`ve always wanted to try!
Followed by the plane and then the rotary sander for the curves

Pity the saw dust fell down the holes in the Breadhook and into the soft varnish below?
Should make a good seal though?
OK, Red Leader?
