Set Overhang on arm w/adjustable tracking angle


I am setting up a Clearaudio Satisfy 9" straight tonearm that is infinitely adjustable for tracking angle. I have set up the 222mm pivot-to-spindle distance. Now I need to set the overhang to 14mm. Since I have to twist the cartridge to set the tracking angle (which is unknown), how do I set the overhang? Both the overhang and the Lofgren alignment require twisting the cartridge. In other words, I don't think I can set the overhang unless the Lofgren alignment is achieved, but I can't set the Lofgren alignment until the overhang is measured. In addition, I have to measure the overhang after the cartridge is twisted. Is this a case where I just have to adjust both alignment and overhang until I measure 14mm overhang and the correct Lofgren alignment?

Doug, if the screw holding the cartridge mounting plate is directly above the stylus, would rotating the cartridge change the overhang? I follow your post and it makes sense to me in every case except the one I mention.

It seems to me that if the cartridge is being rotated along a zenith axis which corresponds precisely with where the stylus tip meets the LP, overhang becomes determined only by the position of the arm pivot point.

I find cartridge zenith alignment to be one of the key advantages of the Mint LP protractor. It is very easy to align the cantilever with the tangent lines at the null points.
