One of the boring sides of this detail. It is no simple polishing job as the valleys formed by the mill are very hard to smooth out.
It is a case of starting with a coarse abrasive and working down to 1200 grade and then I wrap a piece of denim cloth infused with metal polish for the final polish.
That is a reflection of my magnetic tool rack which looks like a row of vertical scratches.
It seems odd doing polishing at this stage but it is the sequence which I choose to do the work in which gives me the finish. When all the riveting and adjuster recessing are complete I can surface grind the inner parts so everything is sharp and pristine.
Somebody on a forum described my work as being clinical and having no soul, maybe he is right and it is dammed hard work to keep it up
