Thank you so much for the prompt reply, so I suppose you tailor made the middle column with the some bearing and bolts, it’s a shame that I don’t have access to a work shop for any tools other than my bare hands
So I think I will continue with the vslot method but bringing the external rod on top of the base plate of the head, creating a angled rail system
As for the rotating mechanism I think I will buy some ready made rotating disc for furniture with bearing integrated then mount a vslot plate on top with the rail system
I’m sorry if I’m not articulating very clearly as I don’t really have too much of an idea too
Was hopping that your middle column is an easier option but it seems like it is being my ability
Thank you so much for your response after all these years much appreciated
