I’ve been slightly obsessed for a long time now with finding a Whitby cannonball nodule good enough to put the hours of prep work into. I have given up while trying to split many, I have split a lot of empty ones, I have chipped a load while trying to split them. I do have a nice eliganticeras nodule that could potentially polish up but the shape just doesn’t lend itself. I found this at the weekend at Runswick Bay and while it would have been nice to have a split nodule with the positive and negative, I could see the potential in this. The actual ammonite is just a crushed up pyritey mess, but there’s a lovely shiny impression lurking below. So far I have uncovered around half of the impression on top and polished up a very small patch on the side, but it’s slow going. I’m trying to avoid using any power tools for the polishing (because dust) and have a decent selection of wet and dry paper (down to 600 grit). I was wondering if anyone with experience of these cannonballs could tell me how fine you need to go with the wet and dry to get a really nice shine, or if there’s something beyond that I should use?
