THE PART
A part machined to hold pressure while turning.
The centre joint passes oil between an upper structure that rotates and an undercarriage that does not. Its sealing lands are ground to microns — the tolerance is visible as a difference in surface, not as a mark.
THE TRANSFORMATION
Ports are drained, flushed and closed with turned bronze plugs. The body is set flat on a blackened ring and the smoked plate rests directly on the outer sealing land.
We take the part from a documented source and assess its condition.
We remove grease, loose corrosion and everything that does not belong to the future object.
We reinforce the structure, smooth the contact zones and design a stable base.
We keep the authentic patina, seal the steel and fit the glass.
We number the piece and issue the certificate of transformation.

DELIVERY & INSTALLATION
Because of the mass, quotation covers dedicated transport, carry-in and — depending on the model — on-site glass installation. Cost depends on location and access conditions.
