Lathe Tool Sharpening

[Mugz]

This seems to be one of my biggest unknowns. I want to make an adjustable jig for my bench grinder that the handle of my tool rests in. Like I have seen in some on-line stores. I can't see spending $60+ on something I can make in the machine shop at work. Any advise is much appreciated. How do you sharpen your tools?

My biggest questions are blade angles. And how do you sharpen the different types of tools...ie: Gouges, parting tool, skew, etc.

Also, what type of grinding wheels should I have (grits?).

Being able to get an edge back consistantly, quickly and accurately is my goal, without having to keep grinding and grinding and grinding till I get the edge I want.
