Re-drilling the steam Inlet port 4
17-Jan-2006
After the Valve Chest Liner is pressed in, the steam
inlet port must be drilled through the liner (alternativily, I could
have put a larger hole in the liner, and tried to line in up during the
pressing, but I choose this route). Prior to drilling, I decided to
increase the hole/pipe size. Then I tapped the hole with a 3/8 pipe
tape.
