These pictures show the front half of the crankcase mated with the bearing carrier. The inset shot shows the back side of the front case before machining it's inside. The shaft (4130 steel) in the lower right is an experiment with my toolpost grinder I made. The rough section of the shaft is an area that was turned with an indexible carbide tool. The turned finish is a bit rough. The grinder did an excellent job however and offered fine control of material removal and a fine finish.
This picture shows a master rod blank taking shape, Finished link rods, front of front case and the bearing carrier.
Here's a continuation of the first Bearing carrier page efforts. The back side of the carrier is rough milled then a slot is made so that turning a taper on the lathe will be easier. Finally the front side of the carrier hs it's front bore made. This was a simple part to make. The tolerances were held to provide a slight interference fit for the bearing cups and a close fit for the front seal.
The last picture is of the front case being face milled by a six inch face mill. The front case has not yet been machined awaiting my drawing up a plan of action for it and it's mating parts. This plan of action awaits the arrival and verification of other parts.
