Grinder size vs. amount of hollow grinding
I am new to turning, and just setting myself up. I need to get a bench grinder for sharpening my turning tools. I am looking at a 6″ model. Is there any reason I should go with an 8″? The larger diameter wheel wouold give slightly less curve as the bevel gets hollow ground. Does this matter one way or another?
Thanks,
Alex

6" or 8"
Personally, I prefer the 8"er. The 6" will do for spindle turning because the spindle diameters are generally smaller. But if you get into bowls where the diameters are much larger you will appreciate the larger sweet spot on the gouges. One turners opinion.
Sweet spot... please explain.
Thanks
The sweet spot is where the tool cuts its best while riding the bevel. You will know it when your there by the nice shavings and ease of the cut.
I'm still trying to figure this out - bigger wheel means less of a hollow grind, which means more bevel left over at the business end?
spelling
So that's where I've been going wrong. I've been pushing harder on the handle, thinking it was the sweat spot. ;-)
preference
I just don't care for c vs. ( I can get more support on the bevel with less hollow grind. After grinding gouges they go straight to the wood, no honeing for me.
Got it.
Unfortunately, I get more support on my wallet with the 6", so that is where I will go anyway!
Thanks for the input.
Grinder speed
I'm talking 1725 rpm slower speed, not the 3450 high speed ;-)
I am aware of the need for low speed. Don't wanna heat things up.
Thanks,
