I am Ken and I will have one of a kind! I'm contemplating drilling and tapping the bottom of the elevation screw and fitting a thick washer to prevent it from lifting out of the nut. It looks to me like the damage to the last nut was caused by the knee being raised up too high. The PO told me that he did a lot of drilling with the spindle parallel to the table.
