Thanks av8tor.The only thing is it has the straight crank shaft.I was thinking about doing it like the ryobi 31 and just use a set screw on the side where the keyway would go,and then put the magnet apposite to kind of balance it out a little,then just use the nut to hold it all on..But being anything that close to the center of the crank and light shouldnt cause any imblance that is noticible.
Or,would it be better to rethread the crank and then use a nut to hold down the hub in the center like a G62,and use 2 bolts to hold the hub on.
Also,how would somone make the square keyway in the hub.What tool do ya use.This engine used the bar stock keyway,1/4x2 inches.[or a little less maybe].
To put a keyway in crank..If you have a mill, use a keway cutter the correct width for key. More easy yet...use a vertical mill bit. You may want to grind the surface a tad, drill about the depth of key-way and then mill the slot. To put a keyway in a hub...you need a broach. Capt,n There may be other ways too!
