I've already asked what sharpening angle turners use for scrapers.
Mine are probably 75-80 degrees and work superbly on the base of bowls. But when I try the Richard Raffan method of scraping the last mill or so of the side out of small bowls and lidded boxes, I run into trouble.
With the tool rest set so that the tool is just under centre, the bottom side of the scrapers contacts the wood. I can only bring the cutting edge into contact with the wood if I turn the tool on its side and sheer scrape.
I think I need either relieve the bottom edge substantially, or re-sharped with say a 60 degree bevel so the top edge can cut.
Or am I missing something?
I'd prefer not to touch the tools, as they work so well on end-grain redgum - as Ern would agree I'm sure.
Solutions please.
