Frank, try your tap in your drill chuck. Lose the tap matic. Drill your hole on size for .050 thick Ti. or less and one size over for thicker than .050. The On size drill is .070. Make sure you're using Morse 2 flute 2-56 taps. Imported parishable tooling WILL give you fits. If I'm building a framelock with .100 Ti, I will come in from the other side with a .086 drill and go half way through the liner leaving me roughly .040-.050 of material for threads.
