Here's a newbee question: I'm need to put an air coupler into my backplate on the oscillator engine. The plans say to tap the hole 6-32 0.250 deep. I start tapping in and the point on the tap dead ends before I've started cutting full threads at the entrance (there is a smaller hole beyond, but the tap dead-ends there). Then the whole thing strips out. Do I grind of the tip on a 2nd tap and continue?
Thanks.
Thanks.
