I've prepared, at least reasonably successfully, rectangular card scrapers and for my cabinet scraper. Now, I've got a set of curved scrapers (LV's set) coming and I'm looking for tips on setting up these curved edges. I think I'm okay for squaring and smoothing the edges, but I'm not so sure about turning a decent burr on these curved edges. I'm particularly concerned with the shorter radius section on the shmoo or goose neck scraper. Any help on handling the burnisher on these curved edges would be appreciated.
