JMW 12.5 ZYX Cosmos azimuth setting

I have been exploring setting azimuth on my JMW 12.5 with a Fluke DMM, Cardas test LP and the (great) MF DVD.

I'm sure I'm doing everything right but have found I need to adjust the JMW azimuth ring to a surprising degree. If you can imagine that the two 'side screws' on the ring, which when in the neutral position, are at quarter to three (on the clock), my set-up has to shift to twenty to two.

I've double checked the TT level, made sure everything' tight and the cartridge alignment is accurate. And i've got the azimuth set within 3% so I'm pretty happy about that, but feel a bit uncomfortable seeing such necessary twist of the ring!

Has anybody had a similar experience with the ring setting?

Thanks

Peter

I use the Tracking Force weight at the back for adjusting azimuth.
since the bore on the weight is off center, When
the weight is rotated to one side, the weight will
be shifted more to that side & cause the Arm to tilt
accordingly.

It's a bit tricky because you can easily slide the weight
off of your VTA adjustment. just recheck VTA as You go
to get both Azimuth & VTA dialed in.

IMO I dont believe the outriggers (when rotated) really do
much to change azimuth. when you rotate It, both of the
"Knobs" move at the same time so it is always balanced.
think about it.
