when I make mine up I take a piece of oak drill a hole thru it about the same size as the case. Then cut this in half and use it to hold the case in a vice. this holds the case for me, and keeps it straight while you drill it. tapping is easy as its brass
Most bits have too much rake for soft materials. If reprofiled with less rake, they work just fine. Great ideas on this thread though.A sharp bit in brass/ copper is not a good idea it will dig in and feeds itself fast.
Break the cutting edge SLIGHTLY with a stone.
