I built my own Turntable and here are the results

I have a gentle criticism: I think it would be better to have a solid link between the tonearm pod and the main bearing of the tt, via the chassis, for many reasons. But the fit and finish are indeed beautiful. Congrats.
Queg, Practical reason: the slightest alteration in the position of the outboard pod with respect to the main body of the turntable will completely screw up tonearm geometry. Theoretical reason; there is something to be said for having the tonearm and turntable in the same closed system, i.e., coupled with respect to outside mechanical and acoustical forces. I tend to favor that school of thought, I don't know a good argument for the opposite approach, but this is not the only time I've seen it (e.g., the Kuzma top-line product cum air bearing tonearm), so there must be one. Not for me though.
First of all, I could probably never make anything this nice. Liguy deserves all credit for his craftsmanship. I am only remarking about a design element that is in fact seen also in the commercial marketplace, apparently with Redpoint turntables and also for sure in the largest most expensive Kuzma turntable, where the airbearing tonearm sits on its own discrete and very massive pod. Possibly Simon Yorke turntables are also built like the one shown, but I can never see quite whether the tonearm pod is coupled to the main chassis in photos of Simon Yorke products. For the reasons I cited above, I don't agree with the de-coupled approach. I am not saying it's "wrong".
Hiho, You wrote, "I would love to be proven wrong because I think having separate armpod is quite convenient in adjusting overhang and maneuvering purpose."

But what about when you quite accidentally brush the arm pod and you then need to stop everything whilst you get out the protractor and relive the unpleasant experience of re-aligning the tonearm? And I mean from go, because you may have altered the pivot to spindle distance by a mm, which others tell us can be critical. Pain in the butt. And this is quite apart from any theoretical considerations that favor coupling the tonearm base to the main chassis, if not the bearing per se.
Not even a cup of tea served on a 2-inch platter? (Sorry. Could not resist.) If the tonearm is on a cantilever, it had better be very sturdy well supported one. But a solid wood or slate or other plinth wherein the tt chassis also resides is a good place for a tonearm to sit.
