With that done I turned to the grip cap as that will demarcate the wrist size for the shaping of the butt stock. With a piece of buff horn trimmed to shape (1 3/4x1 1/4) for a slim grip
a rebate was filed round the edge
and then it was radiused over the top
after which a sand to clean off the file marks.
The holes were drilled for the 2 little brass dowles and it was epoxied into place.
