Graham Phantom damping fluid level.

I always prove alignment with my own protrator (designed on my CAD system) and I am actually very impressed with the outcome of alignment using the Graham jig. As a machinist, I am a stickler for ultimate accuracy, hence all the questions I ask regarding fluid level.

If there is a downside to the Graham arm design, I would say the azimuth alignment/adjustment could be improved upon. I find it extremely difficult to install the armwand and repeat azimuth with any degree of accuracy. Bob obviously designed in the ability to adjust azimuth by moving the magnet up or down but I find it perplexing that the armwand has several degrees of play where it locates on the actual pins where the wand meets the base. If it was my design I would have implicated 2 pins to register the wand postively with the base for exact alignment to make swapping wands a "walk in the park" As it is now, I dread removing the armwand.

Hmm,Frank I don't see/feel that particular wand problem.My jig has more play in it than my friend's,who lives 40 minutes away.I'm willing to bet that I am almost spot on,but want to be sure,hence the WAlly.
Best.

It's definitely a good idea to verify alignment with a good protractor but you mentioned that your armboard was drilled 0.100" out of spec. so how will you fix that?....if that is indeed the case.

Yes,I am calling SOTA tomorrow(I have a new Cosmos),just to confirm.I am not too worried as I am tracing quite cleanly.
The armboard,as I can see,is going to be extremely difficult to drill "spot on"(my friend has a very similar situation with VPI,as of now),since the little peg(yes, I always check everything)must be absolutely perfectly aligned.
The way I view it......there is no adjustability in the Phantom's standard base/mount(unlike the SME mount,which can move,and is not such a bad idea).So with the screws drilled for the Phantom arm mount, which fits into the armboard,AND the holes drilled into the armboard,which screws into the table sub assembly,the amount of slight "play"(in the holes,and alignment)will always allow for a slight "off" position.I am about "maybe" 1/10 inch off,but I have compensated for this with the positioning of the cartridge,in the arm wand.What can I say!!!I don't want to drive myself crazier than I am,already!!!!
Of course I will recheck everything very carefully.
The bottom line is that in my first listening session,I am very close to being in the ball park.This,without playing around with the fluid,which definitely can aid,in voicing the arm.
What I did,this week,in anticipation of setting up my arm,was to go to two of my friends' homes(both have absolutely superb set-ups)and play my ref LP's!Then,I set up my new Phantom,and go from there.
As of now,with the Wally on the way,for re-checking,I hope to be in good shape.-:)

Frank sm,

Yep, my Phantom arm wand needs locate guide pins also. That was one of the first things I noticed . If the pin to plug centers were offset a bit, might have had a tighter fit! I hold the base and twist the arm wand clock wise,taking out the
2 degrees of slop till tight. It's real close every time. Sam
