| MM:
I don't like the wrench idea without a little more info. More specifically, I'd reccomend a 6-pt socket at a minimum. 12 pt wrenches have a tendency to round off the heads, so use a 6 pt wrench.
Preventing the blade from spinning can sometimes be done my holding the blade. Occasionally you'll have to wedge a piece of wood between the blade and the housing.
Otherwise, mm suggestions are spot on. |
