I have three questions really.
1) what is a good grind to undercut the inside lip/edge of a bowl so one can 'grab' it better? I've been using a 40/40 grind mostly and I can't get under the rim right, even if I remove the heel.
2) when would one use a conventional scraper over a negative rake scraper? Maybe I'm too novice to understand but it seems the nrs makes the other obsolete. Is it safe to re-grind my scrapers to nrs or bad move?
3) can I use my skew as a nrs? If not, can you explain the difference/reason?
Thanks everyone, I'm alone on this journey so your help, a couple of classes I've purchased and yt is all I have.
Edit: I have a tormek and a slow speed grinder available to me, both with cbn wheels. If that makes a difference.
