I built my own Turntable and here are the results

Galibier tables don't have detached armboards. In my conversations with Thom I believe that even the Redpoint armpods are bolted to the plinth.

Hiho, Lewm,
very much agreed to say it again.
In fact some designers speak about 'closing the loop' (of resonance) and I guess just what Hiho mentioned.

What I meant is that Red Point and Galibier are different from each other. Red Point uses a separate armpod and Galibier uses a cantilevered armboard attached to the base. I did not mean both brands are different from the DIY turntable. Sorry for the confusion.

Personally I prefer the Galibier approach.

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".

Simon Yorke turntables do not use separate armpods. It uses a cantilevered armboard attached to the base. The armboard is, I believe, marine grade plywood said to be the best sound for SY tables according to their designer after extensive experimenting. He could've easily machine a separate armpod with fancy alloy material but opted to have tighter coupling between tonearm and bearing. I subscribe to such approach because my friends and I had similar experience and none had good sound when the arm is decoupled from the table base. I would love to be proven wrong because I think having separate armpod is quite convenient in adjusting overhang and maneuvering purpose. The Merill turntable takes such approach to the extreme by machining the armboard and bearing mount as one single piece so, obviously, swapping tonearm is not as easy and armboard/bearing mount need to be custom made for each individual arm. Again, just my own experience...
