    Milling the Trunnion Ring

When you make everything from one piece of 4150 alloy steel, you end up doing a lot more machining. This is one of those areas that are left after lathe turning and trunnion milling. This area between the trunnions is brought down to .0025 inch over the adjacent, turned areas. The original had a raised surface of .015 inch in this same area. Files are used to finish this area on our re-creation, just as they were in the West Point Foundry during the Civil War.
