Graham Phantom Supreme?

with regard to the feikert query, the true centre should be measured at the pivot point, not the centre of the cap. They will only be the same when the arm is dead level. Bearing in mind that the pivot is a radius tip in a sapphire cup the actual pivot point will be slightly forward of centre in the cup going towards the cartridge

Thanks, Dover. I was wondering if the P2S measurement using the Feickert becomes relatively straightforward with the cap removed. Could you point the pointer on the Feickert at the interior cup with accuracy? Thanks to all for indulging my question - I don't have a Graham so I don't know the layout under the cap.

P2S distance with the Phantom II can be measured accurately with the cap removed and the Feikert pin lowered into the damping well.
This is recommended by both Bob Graham and Feikert.

This is good to know. Does the well have a detent at the bottom of it for the pin to rest itself centered in the well ? I have damping fluid in there at the momement and connot remember what the bottom of the well looks like. Thanks in advance.

I shared this procedure I used with Chris Feickert, Michael Fremer, and those attending the event about 5 years ago during one of Michael's seminars at RMAF.

Halcro's comment is correct.

The Feickert alignment tool can be used in this manner with the bearing cap removed. The pin on the Feickert tool will position itself center of the bearing cap prior to locking down the threaded pin lock on the tool. Once the pin is centered and locked, the threaded lock for the measuring bar can be tightened. While doing this the platter should remain locked down. Overhang can then be verified with the platter locked down and the bearing cap replaced.

That sounds messy. Unless starting with a dry well, the Feickert's pin will be dipping in the damping fluid - which is so sticky a fair bit of fluid will be removed.
You could fashion yourself a perspex location device for the feickert similar to the one used by the Uni-tractor. It uses concentric circles on the perspex plate to locate the tool over the centre point of the bearing. Maybe you could get one of those locating plates from 'dertonarm' - it looks like it might fit the feickert(?).
I personally use the MintLp arc protractor and think its a far easier and possibly more accurate solution.
