Thumb Hole and Shaping

I removed the 10mm from the other side of the stock/butt.
Drilled out the thumb hole and started a rough shaping of the stock. Haven't done too much tonight, as I'm too knackered after work today.
Once the butt has a basic shape, I have to fit the trigger mechanism.
I know more wood will have to be removed around the thumb hole.
As the design of my trigger, requires me to use my thumb for the safety catch.

The colour difference on top of the stock in the next picture is due to me giving it a quick rub with 400 grit paper. It really brings out the grain.
