Thank you Tao! All the kudos should go to Stacore Bogdan - he is the main responsible guy here. The surface texture indeed turned out very interesting. In this particular rack it will disappear though as the rack is carbon steel and must be painted. However if there is an interest, it can be made from stainless steel, keeping all the textures. Another interesting aspect is the action of damping mechanism in the legs. Although made out of 1" thick steel plates, the horizontal shelves still ring. But when joined with the legs, using our special mounting system, they get damped out nicely.
FYI here is a bit on the damping system. We wanted to try something nobody tried before: A no compromise Constrained Layer Damping (CLD) technique for ultimate damping of the rack legs and as a result the whole structure. The CLD is implemented through a leg-in-a-leg construction: Each vertical section is made of an outer shell and an inner leg, joined by a selected viscoelastic material in a specialized industrial process. Both structures are smartly decoupled, giving a high floor vibration rejection ratio apart from the high inner damping. The outer and inner legs are made out of 5mm thick extruded steel for added mass, rigidity, and stability. The inner chamber can be additionally owner-filled with sand, lead shots or gravel for added mass. All the construction must assembled and aligned to tight tolerances to maintain a perfect rack geometry with outstanding rigidity. The leg structure requires lengthy and complicated manufacture process: CNC pre-processing, precision welding, viscoelastic filling, and CNC post-processing.

Very interesting approach, Jarek. Mass + viscoelastics. Nice cutaway model showing construction; I wish more manufacturers of racks would show details like this. Does the viscoelastic material have a lifespan or need refresh?
Performance wise, the rack and the platforms are making a compelling proposition. Jarek and Bogdan can accommodate all the bespoke requests. To me, it is a no brainer. No other high end rack maker could offer me what Stacore has put on the table.
Well, I'm as sold today on Stacore as I was on day one. Can't comment on the rack concept, but the platform really has helped my tt outperform.
New rack under construction for an US customer. Double width, triple tier
