Just finished up getting these cases prepped for a VMC 177.
This is what it takes to get to this level:
*Degrease the cases
*Media blast
*rough cut the transfers in the case
*TIG weld the cases where i have broken through and also the gasket surface.
*Set the cases up on a mill and mill the surface true.
*Finish working on the ports shape to match the transfers in the cylinder.
*Run the cases in a Graymills parts washer
*Chase all threads
*Run again in a Graymills parts washer
*Clean cases with ZEP brake wash to remove solvent.
