Hi Lou--
Yes, the possibility of a singing shockmount. It does look like
Graham's pipe extends closer to the capsules than it needs to.
Positioning the rubber bands on the ends of the pipe rather than on
the inside of the hoops might be a quick adjustment he can make.
Our goal in the design for the NT-4 that ending up using 3" PVC pipe
was to effectively suspend this heavy mic with as low of a profile as
possible (and that anyone could make with simple tools/materials).
The commercial mounts we tried were too short to prevent pivoting and
too stiff to isolate handing noise enough for our tastes. We are now
cutting away more of the pipe to reduce weight and lingering
suspicions like yours,..

nchPVC_ShockZep.html
But, even with our first design, I found that I was not able to
detect any change with the X-Y cardioid mic in our mount or out of it
in back to back recordings of room tone at full gain. Never tested it
with an omni though.
The NT-4's bulk and front-heavy weight distribution presents a
challenge to be sure. When the mic is lighter, like an NT1-A, you can
see how much easier it is to get further away from the capsules with
less remaining tube:

Better solutions always appreciated! Rob D.
