Update

So, between having to machine the hold down block as well as needing to make the wedge locking arm for the brand new tool post purchased through a leading machine tool distributor; I have been able to make two more castings of the tail light. I worked out all the major issues and the last one I poured looks great. Now that the lathe is all set I'm going to make the backs and license plate brackets. I figure I will make them AXLE MOUNT so they can be sold as a bolt on kit without needing to make your own brackets. I'm always open to suggetions....
