Well I'm half way there, I have a tin shed in Australia
What size were the plates you scraped to make the master Rick?
Hello Darren,
Luckily it was more of a training exercise rather than a proper job, From memory they were about 3"x 4" which is still quite a bit of work, but in soft grey cast iron it's not too bad, an interesting point is that I did the course at the Steelworks Technical Training centre and they exclusively used scrapers made from old files.
One of the steps when scraping from a filed surface rather than a machined surface is to start filing the high spots using the "Belly" of the file and locating the high spots with a standard surface and prussian blue, much the same as you do when scraping.
Best Regards
Rick
