FYI : I'm in negotiation of cooperations which means for the moment, that this part might be also available in USA. and other countries as well.
Will inform later about.
That's a somehow mechanical prozess, you can see the very fine marks on the polished surfaces.
The part comes from a casting process and needs a lot of work on the surface.
I first thought the do rotating polish grinding using some plastic stones etc. but they told me they have machine for it. I always like to see pictures from productions and asking continiously, but often they simple forget it or don't have time for it.
Udpate : Little delay, mirror polishing takes a while. Now Chinese New Year 1st February is comming and will delay some weeks (must be a crazy party, they are already in preparing mode!!).
Anyway : it's on it's way and I'm very excited to see the real results in my hands.
