I went and did it !

How did you drill it out? Did you use a little electric drill or did you use a drill press? What size bit did you use? I need to do that to some of my pipes.

Tab, I used a cutting disk in a drenel to remove the end of the stinger. Then I used an 1/8 bit in the dremel
to open the stem up. The goal was to open it up without expanding the threaded part of the stinger. I had to
go slow and watch my angle, since I was free handing it. I used the 1/8 bit in the shank kind of like a loose
reamer to carve out the gunk and opening a little. The scariest part was when I was working on the button
end. I had to watch my approach as much as my angle since the button has only a hole not a slot. And that
was about 2/3's of the bit. I drilled to the bend from both sides trying insure an unrestricted air flow. Also
I used an 11/32 bit like a router bit to adjust the draft opening, it had a small lip due to the way it was
originally drilled. All I did there was open the draft trough a little, I did notice that the first smoke was
gurgle free. With Nightcap that may not mean much, but for that pipe it is also a first. Good luck, go slow,
and let me know how it goes.
