Would like to know how to grind a 1/2" spindle detail gouge for efficient back hollowing. I've had success deepening an end grain box or cup with my 3/8" spindle gouge with a slightly rounded tip, but after the first couple passes widening the hollowed interior I can't get more shavings - something in the grind must be blocking the cutting edge. Earlier discussion here told me my early problems were due to not keeping the gouge firmly against the side of the opening (along with the tool rest) but I'm still not getting quite the results I'd like. I have no problem with having to use scrapers to remove ridges and refine the curve - that tradeoff is easy given the speed and ease with which a shallow to mid-deepish hollow can be formed.
I'm not familiar with the nomenclature for grinds, but I've been grinding at 30 degrees, pushing the gouge forward as I roll onto the flutes (as shown in Mike Darlow videos) with only a very slight convex curve on the sides of the cutting edge. Thanks in advance for your help.
