sorry, didn't take any photos while machining, i'm really bad when it comes to documenting stuff like that....if it wasn't for my wife i don't think we would even have any photos of our kids...

everything was done on a bridgeport including all the turning. no rotab, all the contouring was done with plunge cuts using "arc" function of DRO for coordinates. then just a bit of sanding with 400 grit and a polish with fiberglass insulation and WD-40. lightening holes were first drilled undersize and then bored with an endmill ground to cut a flat bottom with a slight radius at the corner.

magnet will just go straight in the hub. behind the hub there is a ring that's mounted on a bearing. hall sensor will be mounted there and connected to carb for ignition advance. this will also allow some adjustability for timing. hub has a keyway so timing won't be upset if i tear the engine down.

blog has more photos of the parts. quote my first post to see where it is, same username as here...
