Hi,
Just to start a debate on this :
How do you polish your molds to get a mirror finish?
Do you made it by hand?
Do you use a tool like a luster from NSK?
At our shop, we made it by hand with sanding paper from 320 grit to 2000 grit and to finish with a polishing paste called Polisol. We are thinking to buy a luster but don't know if it can do the job. This is why I'm here asking this. I would like to have some advice on what not to do with some material. I've ever heard that a paste with ammoniac is to be avoid in aluminium.
Also, I'm searching a place where I can have information on finish. I know they are grade like A-1, A-2, A-3 finish, but never see a chart that explain each finish with picture.
It would be great if we could make this thread THE PLACE to get information or links on this.
Thanx!
Edit: I've post this thread here as the polishing is a big part of making a mold.
