A masterpiece! Are those MBL components in the background?

After some years buying, changing stuffs...I felt tired because some audio gears I like is really much over my budget and also some expensive ones I got did not deliver the right sound I expect. I started looking around at DIY forum and studied how people DIY. A lot of useful information found and people hard works inspired me very much then I decided to start to do my own.

First think came in mind was platter bearing. How to design and make a bearing that can bear a heavy load ( I decided to make very heavy turntable to mitigate the vibration factor which I think very much impact to sound quality) and spin freely by minimizing the side friction?. I see some people did the inverted bearing type and I did.

When I firstly completed the bearing, I found that the axe was not spinning well because of high friction to bearing housing despite of use of oil bath. I inserted a layer of thin brass bushing and it worked very well.

Very, very nice indeed!!!
A little more detailed description would be nice , though....
Base and platter solid ? Looks like some kind of adjustment on the feet?
Etc.Etc.

Thank you. Appreciate much if other viewers of this topic take some times to share the idea and comments.

Platter is made by stainless steel SS304, machined to surface roughness 1, at my machining shop. Platter thickness is 70mm. I could not find that thick plate around at that time so I decided to weld 02 of 36mm plates together. It's really high craftsmanship of my welder when no one can realize that is two welded plates but just like a single one. Trust me, you can not see any lamination between two plates with normal eyes.

Nothing much to say with platter, all works were done by CNC lathe. Platter itself is 25kg weight. Hard to carry, so I have to drill two threaded holes along side in order to insert the lifter.

Is there a resonance in the platter? I like the toys...

In my knowledge, resonance exits in every materials...I have no tool to measure it but I tried to keep it as much pure as possible.
