I just got a great email from Harmony Castings showing some images of the first pour of the crankcase top casting.
This is the first sample and is now being x-rayed to check for porosity. Once it passes muster for that it will be sent to me.
I’ll scan the part using a Romer Arm to make sure the exterior surfaces are within the tolerance range of the CAD model.
If the exterior surfaces are all within spec the next step will be to cut off both deck surfaces to check coolant passages for any signs of core shifting. Unfortunately, this will make the part unusable for anything but a machining test part.
I should get the part next week and start the process. The crankcase lower will be poured sometime next week and then i get to repeat the process.
