The new recess is used to hold the blank ready for drilling
A Maglite has a diameter just over 18mm, so a 15mm Forstner bit is just right for starting the hole.
The hole can be enlarged so that the Maglite is a good fit
It is checked from time to time to make sure it is not too tight or too loose
The final shape is a matter of taste, so long as the stand is heavy enough to hold the Maglite securely
The project is completed with a final polish
