Using the Graham B-44 factory alignment jigs to position the arm for the spindle pivot distance and then to mount the cartridge.
The end result , I found them to be of ease of use, well thought out and a very accurate design.
Once the Feikert protractor arrived, I checked my set up against the Graham factory jigs and my ability of using them.
First up , the Feikert read a pivot to spindle distance of 216.5 mm for the Graham Phantom arm.
Next step I was able to land the stylus on the first point of reference with little problem. It was bang on the mark.
The third step which took a little longer, was to position the stylus in a grid to check to see if the cantilever is parallel with the lines on the grid, which it was. Oh yes, the Feikert disk is reflective.
For us older guys, this is where a photographers lope and mag light came in handy.
Thinking about it as I type this, did I need to buy protractor? I also have the MintLp arc tractor on its way too.
Using an arc protractor made specific for my arm and table is going to be interesting.
Its a learning experience for me, its fun and in the end I will have complete piece of mind knowing the geometry of my arm and cartridge are exactly to spec.
Good Listening
