Get yourself some Diamond stones, Dia Sharp or Titman. 125 grit, 1000, and 10000. It takes no time at all, with no risk of overheating. All my chisels and plane blades have been sharpened this way, but my gouges get finished with a strop.
There’s no need for a guide. They take forever to set up and are a waste of space. You’ll get a feel for it in no time.
Oh, and pre war Addis chisels and gouges keep their edge for a long while. Nothing modern even comes close, except maybe very top quality japanese stuff, but they are ten times the price.
