As I have no workshop yet, and not sure if I will have. I decided to go old school with some materials I brought over.
Its amazing what you can do with files, rasps, and some wet and dry. I did use a cordless drill for the bolsters (which are stainless and where a nightmare) and the holes for the pin (which are silver..). I took the bolsters down to 4000 grit and then used some toothpaste to get a polish (told you it was old school).
I recon this took five times longer than if I had a grinder and some power tools so its not something I will make a habit of, however, it was very satifying in the end..
