Drawing and machining a curved slot

[Barrie123]

Good afternoon.
I am making a clock to sit in a 400mm long x 40 mm thick a 50mm wide base
The clock is 400mm in diameter.
I wish to have it sit in the base by 12mm,
How do I draw the slot for the clock to sit in to follow the 400mm curve and then machine the curved slot, as per my drawing.

One potential quickly drafted and toolpathed solution is presented here (recalculate the toolpath as it is not calculated for a smaller file size).

You could also do this with a moulding toolpath.
