Making a duck call jig

[JScott]

I made a little progress over the weekend.  This jig requires a 0.625" through hole.  I drilled a pilot hole 1/2" with a twist drill and then followed that with a 0.625" end mill.  It worked well but I had to peck "drill" the last portion of the hole because the end mill flutes filled with chips.

   

This is how it looks with the hole chamfered.
