Hi Steve, the link you've posted to the jig, is just that, it is ONLY the jig for creating a fingernail profile. You would also need their 4 piece set, which comprises two bases (they lock the V-arms in position) a table (can be set at an angle, suitable for basic 'straight grinds') and one V-arm. Their method for creating a 'standard' grind on a gouge is to place the end of the handle in the V and the arm is adjusted to appropriate length for the cutting edge to rest on the grinding wheel at your chosen angle. The fingernail jig (as per your link) is used in combination with the V-arm, to set the angle at the tip of the tool but also the angle of the side wings. One problem with the original Wolverine system and with Robert Sorby's Tormek fingernail jigs are they are limited in the diameter of the gouge they can hold. There is a newer version of the Wolverine so that may have been addressed. If it helps the Trugrind can cope with gouges up to 1" in diameter. And it can cope with all the basic tools, even skew chisels, with ease. Unfortunately you are a bit far from us for a visit, but you would be most welcome if you did fancy a trip to one of our 'hands on' evenings.
One last thing I will say is don't be fooled by these things being called jigs; they aren't, they are guides. If you keep the same part of the cutting edge against the grinding wheel it will keep on grinding, leaving a lovely flat on your cutting edge. All they do is maintain the angle. It is up to the user to move the tool correctly to achieve the grind you want.
As has already been said, your best bet is to spend some time with other turners who can show you the techniques of shaping and sharpening your tools.
Hope that helps,
