halcro, the vta is adjusted using the micrometer ath the top of the post, there is a thumbscrew on the side that you would loosen first, adjust the height and then retighten the screw to lock everything solid. the micrometer has a long rod attached to it that extends to the bottom of the pod. this enables the 1" shaft to be raised and lowered as required.
lewm, i use the 3 thumbscrews at the bottom to adjust for azimuth. it doesn't matter how the armboardor pod ultimately seats, level or not, the azimuth is measured at the stylus using a fozgometer.
