[SEL] Hercules or Economy J mixer

[Glenn A Karch]

Curt,

I don't know for sure why Hercules cast the mixer around the pipe nipple.
Very early mixers had the threads cut directly onto the J mixer casting.  I
suppose there was a problem with breakage.  If you manage to unscrew or chip
out the nipple from the mixer, you will find that the threads were somewhat
melted together.  You can't screw a new nipple in because of the
distortion..  The only way to put a new nipple in is to grind the threads
down some untill it can be forced in along with JB weld.  It takes a little
trial and error preparation before you finally line it up and drive it home.
The hole isn't deep enough to use a pipe tap to clean up the threads unless
the tap is shortened accordingly and then it may still be tricky.
