self feeding scrapers?
I had an experience last night for which I can not come up with a reasonable explanation. While using a LH bowl scraper to clean up the bottom of a fiddleback redgum bowl it got blunt, rather than sharpen it I swapped to my round nose scraper instead as the amount I needed to do was small. The sharp roundnose scraper self feeded and gave a poor finish, repeating it with the now sharp bowl scraper did not. The scrapers are the same width, sharpened on the same stone, 1mm difference in thickness (thinner being the bowl one), speed was about 1000rpm and the radius is similar, just the portion rounded differs between the two. Anybody else had this experience?

Hmm, nice little puzzle.
Tool contact point the same height both times?
Only guess is that the quality of the steel was different and you had a bigger burr on the round nose scraper.
Len Smith of the Woodsmith once told me to take the burr off scrapers when using either really hard or really soft woods.Cheers, Ern

Yeah, well the other thing is 'fiddleback' ie. unevenly grained timber. So it might be the wood rather than the tool.
