Larry; First, Shopsmith has some great resources for all sorts of information, including sharpening, on their website. Check out this link: https://www.shopsmith.com/woodshoptips/tips/070102/index.htm Hopefully some of your questions will be answered there.
As far as what I do for turning tools, well as I mentioned, I do use the SS guide for many of the lathe tools. It works for the scrapers, the roughing gouge, the parting tool and the skew. I use 150 grit on the sanding disk and the tools work fine right off the jig, except for the scrapers. For them, once the angle is touched up, I use a burnishing jig from Veritas for establishing the burr. After that, the scrapers cut fast and clean.
To create the "fingernail" profile on your spindle gouges, the easiest way is to follow Chris' advice and get a Wolverine jig and a grinder to match it. If you would like to try your hand on an alternative method, one which will require climbing a little bit of a learning curve, you might try the method shown in Keith Rowley's book "Woodturning-A Foundation Course." This is a great book, by the way, and has helped me quite a bit. In it, Rowley describes a simple table he attaches to a bench grinder and a method of grinding that will result in a mild fingernail profile. For bowl gouges I use the "good, general profile" that Rowley shows on page 91of the 2009 edition of his book. It is fairly easy to grind this using the shopsmith grinding wheel with the wooden table.
Hope this is helpful.
