Shizuoka AN-S need help tramming head

Hi all, I bought a Shizuoka AN -S about a year ago, converted to smoothstepper/gecko controls and finally got it operational somewhat. I have successfully been able to run a few programs and seemed ok, but I noticed when I used a fly cutter one side of the cut is way off, cuts deeper than the other as it turns, so I checked the tramming of the head/spindle and its definitely off a degree or so, problem is I cant seem to figure out how to rotate the head, I loosened up the 1 but on the right side of the round vertical base which appeared to be what locks the angular movement but it doesnt budge at all, I tried looking in manual but it's just parts and drawings, has no mention of adjustments etc. Anyone have an AN-S that has been able to tram it? Any help is appreciated as it's really a nice machine just cant see the point of putting more time into it if it's going to be way off.


Thank you.

Is this the machine we are talking about?

There has got to be more than one bolt holding the head in tram. Try loosening this plate on both sides with the dowel pin removed.

Mine is the cnc version but yes the head looks the same to me.

I know this thread is old, but I am in the same boat with my Shizuoka AN-S mill I need to Tram it but cannot figure out how. I have one nut and bolt on the right side of the head, unlike my Bridgeport that has the adjustment nut, my Shizuoka AN-S mill does not have anything resembling an adjustment nut. Has anyone figured it out yet?

Please take some pictures of the machine. far away and the head stock. where it bolts on both sides.
