The Scraper's cutting edge is formed by one step on the grinder. The grinding action forms the hook.
Alan Batty recommended 70° with the under side ground back at 40° (a relief grind). (I and many others recommend you re-grind the tool to be a negative rake scraper.)
Marty Kiminsky noted that 70-80° is generally recommended for this tool. (He did not note a personal preference though.) See also, "Woodturning" magazine, issue # 352.
Some recommend the use of a belt sander (i.e., one which is bolted to the bench, not a hand-held one). I've used that and the Tormek with the Tormek SVD-110 Tool Rest. Both work, but the Tormek grinds away less metal, so that is what I prefer.
