THere's been a few threads recently related to tools. Everything from what tools foar a new turner, to what brand is good, to where the flute is located withing the shaft diameter.
So, for all of you tool junkies, which I think is mostly all of you. let's try to answer some questions.
If you're turning a very basic open form small bowl, let's say 6"-8" diameter x 2" high. this is a common size for many turners especially beginners. (those of you who start with a 20" log may want to sit this one out) what tools do you use during the process?

Pictured below is a bowl turned many years ago for it's simplicity and as a reference.

For myself, I would probably use a 1/2 bowl gouge (3/8" flute) for the majority of the work, roughing & shaping. I don't really care about the flute shape, all the tree main shapes will work just fine. I use the wing of the gouge on the outside in a shearing cut as ma final pass to prepare for sanding. I usually use a parting tool to define the foot and on occasion a scraper to clean off the nib in the center of the base (outside) and give a flat bottom.
So, what type of tools would you use to make a bowl like this?

Well, being an odd duck (Oregon Duck at that...) I start with a Big Ugly tool (1 inch wide scraper) for all of the shaping and roughing. I will take a 1/2 inch or 5/8 inch gouge with a 45/45 grind for finish cuts on the outside, then follow that with a shear scrape for finish cut. On the inside, pretty much the same process, scraper for roughing cuts, a pass with a bowl gouge, 45/45 for down the side, then 70 degree bevel BOB tool with a ) shaped nose profile. I shear scrape the transition and walls for final pass, and it varies for going across the bottom. Some times the gouge is fine. Some times a shear scrape for a rounded bowl bottom, or a NRS for a more flat bottomed plate or bowl. I don't use the NRS on the walls. I use scrapers with a burnished burr for all shear scraping.

I might use a scraper to clean off the tool marks as a final cut, as well as a bowl gouge like you describe to get to that point.
I also use a smaller bowl gouge for the light cuts needed to finish off the bottom.

As likely the least experience turner to talk on this so far, I'll nonetheless jump in.

I have a Thompson 1/2" U shape bowl gouge and a Oneway 1/2" parabolic shape bowl gouge that I swap back and forth as they dull. Both are ground to about 60 degrees +/-. I'd use both of them to turn your bowl, Ed, likely using a 1/2" "bottom of the bowl" gouge to finish up the inside bottom. I have a Hunter #5 that I may call into action, too. For the outside, I'd use the same two bowl gouges for everything.
