I agree with all of the above.
Some years ago I bought a lathe which came with an 8 inch slow speed grinder and a white and gray wheel, along with the Wolverine grinding jigs. I put another white wheel on in place of the gray wheel and have a flat tool rest on that side for the skew and scrapers, other side for bowl gouges.
Later I bought a used Tormek 7 with a bunch of jigs, rests, etc. for close to what I paid for the lathe, grinder Wolverine jigs, Oneway chuck, and bench.
The Tormek is wonderful for bench chisels, scissors, knives, etc., puts a razor sharp edge on everything. Same can be achieved with a piece of 400 grit paper on a granite sink cutout, or the lathe bed for about $700 less.
Knowing what I know now, the hot set up would be a generic slow speed grinder with two white Aluminum Oxide wheels and the Tormek bar and bowl gouge jig, and a flat rest for scraper and skew. Later, even much later, replace the Alox with CBN.
I would hone the skew with a piece of 400 grit on the lathe bed to get that razor sharp edge - which will be gone in a minute. Hone the inside of the bowl and spindle gouges with a piece of rolled up 220 - 320 sandpaper for the finish cuts. When hogging out the inside of a bowl a little tearout does not matter, go grinder to bowl.
If the object is to make turnings, there is little time for elaborate sharpening rituals. I walk in shed, turn on grinder 12 inches from the tail end of the lathe, sharpen, turn, sharpen, turn, etc. finish bowl, turn off lathe, turn off grinder, leave shed.
So much timber, so little time.
