  • Once you have filed the parting line, you then need to grab the flyheel inbetween the spokes, preferably with a six jaw chuck , since this needs to run as true as possible to look correct and be as balanced as possible when the engine is running. It will also allow you to machine most of the flywheel without rechucking it and makes it easy to machine the opposite side.

The first thing you need to do is go around the inside of the rim between the spokes and file the flash off the parting line of the sand casting.
