O2 bung brazing/welding?

[Shannen Durphey]

I've been successful drilling a hole in the pipe/header large enough
for the sensor portion of the O2 sensor, and welding an 18mm spark
plug anti-fouler around the hole.  The anti-fouler needs to be cut
short enough so the sensor protrudes into the exhaust stream.  If you
find a source for more "professional" bungs, please post it.
