Hugh,
I started a thread a while ago, on here about what I'd been scrapping, since then, I've finished scraping the Clarkson, milled oil grouves in it, made way covers and nearly got it back together. I'm working towards making a video about it and the tools that I made to scrape it. Several projects on the go, including a low speed grinder. Casting not scrapping!
Cheers, Matthew.
